Perception, knowledge and action in infancy
Cognitive development: the development of behaviors that relate to perception, attention, thinking, remembering and problem-solving.
Mental representation: an internal description of aspects of reality that persists in the absence of these aspects of reality.
Traditionally a key aspect of the distinction between perception and cognition.
But, its applicatoin to infancy has not been so productive as once seemed likely.
Right from birth, infants perceive the world in a sophisticated way, and in the early months they develop perceptual abilities that ‘fill in the gasp’ in perception so that invisible parts of objects are perceived, and that are temporarily hidden are treated as continuing in existence.
Early limitations in vision; are they really a problem?
Visual acuity: the ability to make fine discrimination between the elements in the visual array.
Newborns’ vision is significantly poorer than that of older individuals.
Visual acuity is probably around 1/30th the level of perfect adult acuity.
Young infants have poor control over focusing the eyes (visual accommodation).
These limitations are short lived, both acuity and accommodation improve rapidly during the first 6 months.
Although much of the detail of the visual world may be not available to young infants, these limitations should not affect perception of the larger scale structure of objects.
How can we investigate infant perception?
The visual preference method
Visual preference method to determine whether infants have preferences for certain stimuli. They are shown two objects side by side, and the amount of time they spend looking at each one is then compared.
Such looking time difference is defined as a visual preference. Such a preference implies discrimination, otherwise there would be no basis for preference.
The two stimuli are presented over a series of trials in which left-right associations are systematically varied.
Habituation techniques
If the infant looks for shorter periods over trials, this implies that progressively more of the stimulus has been committed to memory. This if infants habituate they must have form of visual memory.
To investigate visual discrimination.
Shape perception in newborns
Even newborns are capable of perceiving differences between simple shapes such as crosses, triangles, squares and circles.
The components of shape
Newborns can discriminate between different line orientations.
During habituation, young infants have a tendency to process on the basis of the simplest variable.
Even newborns perceive simple shapes as a whole and not just as a collection of parts.
Newborns perceive a three-dimensional world
Size constancy: understanding that an object remains the same size despite its retinal image size changing as its moves closer to or away from us.
Shape constancy: understanding that an object remains the same shape even though its retinal image shape changes when it its viewed from different angles.
Evidence for both shape and size constancy has been obtained with newborns.
Found out with habituation.
Infants respond to a change in true size but not to a change in retinal image size.
Retinal image size: the size of a visually perceived object on the retina of the eyes.
Perceptual development in the first six months
Perception of object unity
Object unity: understanding that an object is whole or complete even though part of it may be hidden.
Common motion is one principle infants use to perceive object unity.
But, newborns do not perceive object unity.
There is a picture of gradual emerge of object unity during early months.
Perception of object trajectories
For example. Whether, if an object moves behind and occlude, the infant fill in the invisible part of its trajectory.
6-month-old perceived traject continuity.
4-month-olds only did when the occluder was very narrow
They perceive trajectory continuity when either the time out of sight or the distance is short.
2-month-olds perceived the trajectory to be discontinuous even with the narrow occluder.
There are age related improvements.
Perception of subjective contours
Subjective contour: when only parts of an object are presented, the remaining contours are ‘filled in´ in order hat the complete shape can be perceived.
This ability develops shortly after birth.
Face perception
A form of face perception is present at birth.
Infants within a few minutes or hours after birth prefer face-like patterns.
Mechanisms responsible for this preference are in question:
Discriminating between faces
There is evidence for discrimination between the mother’s and a female stranger’s face by young infants and even newborns with only a few hours contact with their mother.
Preference of attractive faces
2-month-old infants and even newborns will look longer at a face rated attractive by adults than they will at faces rated less attractive.
This preference appears to be driven by the arrangement of internal face features since it is still found when external features are concealed.
Prototypical face: the most typical example of a face. Produced when many different faces are averaged.
Infants may possess an innate ‘face recognition system’ that triggers attention to faces and which is maximally stimulated by a prototypical face.
An alternative possibility is that the attractiveness preference within a few days of birth arises from experience of faces in the immediate postnatal environment. Some kind of facial averaging could provide a learned prototype that attracts more looking.
Perceptual narrowing and face processing specialization
Differences in face experience may explain evidence of growing specialization for faces of particular species, race, gender and age.
Very general abilities become more narrowly tuned as result of experience. This narrowing is likely the result of the extensive social and perceptual experience accumulated with own-race caregivers and other adult individuals within the first year of life.
Preference for female faces is nor present at birth, and is found by three months. This preference develops it only appears for same-race faces.
Interpretation:
Imitation
Newborns are capable of imitating facial and manual gestures.
Newborns have no experience of seeing themselves making the gestures, and the suggestion is that this early imitation is based on inter-modal matching between seeing a gesture and the sensation of producing the same gesture.
Imitation may have a very early role in language development. Newborns produce appropriate mouth movements in response to ‘m’ and ‘a’ sounds produced by adults. This occurs even when infants have their eyes closed.
There is an inter-sensory component to these abilities.
Voice perception
Even prior to birth the fetus picks up auditory information.
26 gestation onwards, fetal heart rate changes consistently in relation to auditory stimulation.
There is also responsiveness by 12 weeks gestation.
Newborns reveal the ability to discriminate between certain speech syllables.
Very young infants appear to discriminate speech distinctions that exist in other languages but not in their own, later narrowing their discriminative capacities to distinctions contained in their own language.
Voice and speech discrimination
Newborn infants show an attentional preference for their mother’s voice compared to that of a female stranger of similar age.
Speech sounds are available in the uterine environment and the unborn child learns about auditory information.
Fetuses and newborn infants are capable of encoding speech in sufficient detail to extract differences in rhythm and/or intonation between two passages.
Preference for infant-directed speech
Infants prefer to hear infant-directed speech over adult-directed speech.
Motherese: infant-directed speech, the speech that adults and children over 4 years old use when addressing an infant.
It not only attracts the infant’s attention, but presents clearer examples of speech from which the infant is more capable of learning relationships between words, and objects and actions.
Jean Piaget and the development of object permanence
Piaget’s view was that infants were not born with knowledge of the world, but instead gradually constructed knowledge and the ability to represent reality mentally (constructivism).
Object permanence: the ability to understand that even if an object is no longer visible, it continues to exist.
The ability to maintain a representation of object that are out of sight, leading to awareness of their permanence.
According to Piaget, prior to the age of 9 months, infants do not exhibit object permanence. And although this appears in simple form at 9 months, it does not develop fully until near the end of the second year of life.
Search onset and the A not B error
By 9 months the infant’s reaction to disappearance has changed. Now, if an object is hidden, the 9-month-old would search for it successfully.
This indicated the beginnings of the ability to represent the absent object.
A not B error: an object-searching error that is often made by 8-12 months olds. Infants making this error will look for an object where they have most often found it, rather than where they last saw it hidden.
Piaget took this as evidence that their representation of the hidden object was not yet fully objective, they repeated an old action to ‘recreate’ the object, as if their own actions defined its existence.
Infants have an awareness of object permanence and an advanced general understanding of the physical world.
The violation of expectation technique
Infants are shown an event and are then shown two new events, on of which is consistent with everyday reality (possible) and the other is inconsistent (impossible). Infants will typically look longer at the impossible event because it violates their expectancies.
Young infants reason about the number of objects in an event
Infants possess core knowledge of the world, on the basis of which they reason about the events that they see.
Infants reason about the number of objects involved in an event.
Young infants discriminate different numbers of items
Infants are capable of discriminating between arrays in terms of numerousity, though only in the case of small numbers.
Subitising: the ability to perceive directly the number of items without consciously counting them or using another form of calculation. This ability only applies to very small numbers.
Infants also appear to be able to discriminate between larger numbers, although in this case they appear to be using a distinct system for detecting approximate differences that only works when the ratio between smaller and larger number is large.
Young infants can count
Young infants have an understanding of addition and subtraction.
When infants saw incorrect numeral outcome, they produced brain activity that matched that obtained from adults when they encounter incorrect outcomes.
Search failure is not due to lack of motor skill
Infants only have problems with cases where one object conceals another.
This can be because they have difficulty perceiving or understanding the relationship between object and occluder.
Seeking an explanation of the A not B error
Response perseveration?
Response perseveration: Repeating a previously learned response usually when it is no longer appropriate.
Infants make errors even if they have only seen the object hidden and revealed at the A location, and have not been given the opportunity to reach for it.
Memory limitations?
It is possible that infants have more profound memory limitations than adults.
Infants rarely make errors if they were allowed to search immediately for the hidden object at B.
It can be that interference occurred between memory of the object at the first location and memory of it at the new location, such that information about its prior location often predominated over the more recent information about its new location.
Errors occurred even when the object was fully in view at the B location.
Place A as a container
One possibility is that though seeing an object hidden and finding it, infants quickly learn to treat place A as a container, and that it is this knowledge rather than knowledge about the specific object hidden that leads to search errors. And if we consider infant’s everyday experience, it is quite possible that their ideas about containers is to some extent magical.
When hiding took place without overt communication between investigator and infant errors were reduced on B trials.
It is possible that social information has a negative effect on search performance though misinterpretation of the communicator’s message.
Attention
A link has been found between success and continued attention to location B during the delay.
When attention is distracted during the delay perserative behavior increased.
Longer looks and a larger percentage of time spent looking during a focal attention task correlate positively on a looking version of the AB task.
There is a role for individual differences in the likelihood of search errors.
Infants frequently perseverate when they are fully attentive, so inattention is unlikely to be the sole cause of preservation.
Frontal cortex immaturity
The frontal cortex is involved in planning and guidance of action, executive functions.
Diamond claims that immaturity of frontal cortex in early infancy leads to deficits in infant’s ability to use certain types of information to guide action. Infants are unable to use their memory of the absent object to inhibit an old response that is now inappropriate.
There is relevance of the frontal cortex in the AB task. There is an association between successful B trials and greater frontal EEG activation.
Converting knowledge to action
When faced with the A not B task, infants are aware of the continued presence of the object, but are simply unable to use this information to guide action.
Initial success at finding the object at A is based on trial and error manipulation of the cover at which it disappeared rather than knowledge of the existence of the object. And they repeat this action whenever and wherever the object disappears, and even if the objects is placed in view at the B location.
Development of frontal cortex involves formation of links between object knowledge and action, leading to accurate search based on knowledge of the object’s position rather than trial and error.

The scope and Methods of Developmental psychology
Introduction
Developmental psychology: the discipline that attempts to describe and explain the changes that occur over time in the thought, behavior, reasoning and functioning of a person due biological, individual and environmental influences.
Maturation: aspects of development that are largely under genetic control, and hence largely uninfluenced by environmental factors.
Developmental psychologist study age-related changes in behavior and development.
Age itself causes nothing. So we need to look for the many factors that cause development to take place.
The assumptions and ideas we have about human nature will affect how we rear our own children and how we interpret the findings from studies of children.
‘Folk’ theories of development: ideas held about development that are not based upon scientific investigation.
Often reflect the issues that psychologists investigate, with aim of putting our understanding on a firmer, more scientific footing.
Defining development according to world views
The manner in which development is defined, and the areas of development that are of interest to individual researchers, will lead them to use different methods of studying development.
Two paradigms:
Organismic world view
The idea that people are inherently active and continually interacting with the environment, and therefore helping to shape their own development.
Emphasizes the interaction between maturation and experience that leads to the development of new internal, psychological structures for processing environmental input.
Each new stage in development represents an advance on the preceding stage and the individual does not regress to former stages.
Each new stage presents new characteristics not present in the previous stage.
Mechanistic world view
The idea that a person can be represented as being like a machine, which is inherently passive until stimulated by the environment.
Ultimately, human behavior is reducible to the operation of fundamental behavioral units that are acquired in a gradual, cumulative manner.
The frequency of behaviors can increase with age due to various learning processes and they can decrease with age when they no longer have any functional consequence, or lead to negative consequences.
Development is reflected by a more continuous growth function, rather than occurring in qualitatively different stages, and the child is passive rather than active in shaping its own development.
Behaviorists represent this world view.

Theories and issues in child development
Introduction
Theory of development: a scheme or system of ideas that is based on evidence and attempts to explain, describe and predict behavior and development.
Two types of theory:
Motor milestones: the basic motor skills acquired in infancy and early childhood, such as sitting unaided, standing, crawling and walking.
The development of motor skills has very important implications for other aspects of development.
The ability to act on the world affects all other aspects of development, and each accomplishment brings with it an increasing degree of independence.
Maturational theories
Motor development proceeded from the global to the specific in two directions.
Development is controlled by a maturational timetable linked particularly to the central nervous system and also to muscular development.
Dynamic systems theory
A theoretical approach applied to many areas of development which views the individual as interacting dynamically in a complex system in which all parts interact.
Not all infants go through the same motor developmental stages.
Infants’ acquisition of a new motor skill is much the same as that of adults learning a new motor skill. The beginnings are usually fumbling and poor. There is trial and error learning and great concentration, all gradually leading to the accomplished skillful activity, which then is usually used in the development of yet new motor skills.
All new motor development is the result of a dynamic and continual interaction of three factors:
Piaget’s theory of development
Developmental psychology before Piaget
Behaviorism and psychoanalysis.
The child is seen as the passive recipient of their upbringing. Development results from such things as the rewards and punishments.
Fundamental aspects of human development according to Piaget
Children are active agents in shaping their own development, they are not simply blank slates who passively and unthinkingly respond to whatever the environment offers them.
Children’s development and behavior is motivated largely intrinsically.
Children learn to adapt to their environments and as

The nature-nurture debate
Precocial and altricial species
Precocial species: they young are physically mobile and able from the moment of birth or hatching.
Altricial species: are helpless and do not have this capacity at birth.
Nativism and empiricism
Nativism: the view that many skills or abilities are ‘native’ or hard wired into the brain at birth, the result of genetic inheritance.
Empiricism: the view that humans are not born with built-in ‘core-knowledge’ or mental content and that all knowledge results form learning and experience.
Cognition: mental activity.
Mental age and intelligence quotient (IQ)
Chronological age (CA): a person’s actual age
Mental age (MA): an individual’s level of mental ability relative to others.
Intelligence quotient (IQ): a measure of a person’s level of intelligence compared to a population of individuals of approximately the same age.
Originally (MA/CA)*100
Intelligence tests
Four important notes about IQ:
What is intelligence, on ability or several?
To a large extent how intelligence is defined determiners how it is measured.
There are those who argue that a general intelligence ability underlies performance on all intelligence tests.
Others suggest that intelligence is made up of a number of specific abilities or subskills.
Still others have argued that performance on intelligence tests is unrelated to our ability to ‘live our lives intelligently’.
Intelligence test items
Many test divide intelligence into two broad abilities.
Verbal subscales
Similarities: the child is asked in what way things might be similar.
Comprehension: measures the child’s common sense and understanding.
Recall of digits
Performance subscales
Block design: This child is given a set of blocks with colored patterns on them, and asked to use them to make patterns that the tester knows.
Copying: the child is shown a drawing and asked to copy it on a sheet of paper. The drawings are initially simple and become progressively more complex geometric shapes.
Controversies and issues in intelligence
Heriability: a statistical measure that describes how much of the variation of a trait in a population is due to genetic differences in that population.

Prenatal development
Prenatal development: the development of human individuals before they are born.
Foetus: (by humans) the organism 12 weeks after conception until birth.
Embryo: the developing organism during the period when organs are forming. In human from first cell divisions until about 10 weeks.
Neonate: an infant less than a month old.
Postnatal development: the development of a human individual after he or she is born, particularly during early infancy.
Organogenesis: the process of organ formation in very early development. In humans this is from fist cell division until about 10 weeks.
Throughout life, normal development demands constant and complex interactions between genes, environment and the emerging organism.
The impact of prenatal experience occurs on multiple levels. From biochemical factors influencing gene expression, in the foetus’s neuronal circuitry to characteristics of the mother’s lifestyle affecting the foetal environment.
Exquisitely timed, complex interactions between the genes and environmental input affect acquisition of neuronal identity, guidance of axons to target, induction of connections between cells or synaptogenesis, and also programmed cell death or apoptosis.
Processes and sequencing of brain development
Ectoderm: the outermost of the three primary germ layers of an embryo. The central nervous system and skin, among other structures, develop from ectodrem.
The other two are endoderm and mesoderm.
During he embryonic period, the central nervous system brings as cells of ectoderm, one of three germ layers. The germ layers are the foundation for organ formation.
The endoderm thickens and becomes the neural plate by day 18 of gestation. By then it is already differentiated into cells that will become forebrain, midbrain and hindbrain.
The neural plate folds to become the neural tube, and by the end of the first month the embryonic body has the basic cranial-caudal (head to feed) organization.
Cells are born, and begin extensive migration to their eventual location where the will become their final forms.
Neurogenesis and migration continue right up to about the sixth month of pregnancy, and are followed by extensive changes in individual cells that program them for the myriad tasks awaiting the emerging brain.
Despite their ultimate high level of specialization, the 1010 nerve cells that will comprise the brain originate from one single

Emotional development and attachment relationships
Introduction
Emotional development underlies many other aspects of development, and has serious implications for how we conduct research with children.
Children’s emotional development can broadly be divided into three areas.
Expressing and recognizing emotional expressions
Are expressions of emotions innate?
Cross-cultural evidence
There is good evidence for the universality of human facial expressions of emotion.
Understanding of how emotions are conveyed through facial expressions is universal, but does not necessarily mean that understanding emotional expressions is innate.
Expressions of emotion in infancy
Infants from birth spontaneously display a wide repertoire of emotions though their facial expressions.
Basic emotions: happiness, interest, surprise, disgust, sadness, distress, anger, fear.
Complex emotions: pride, shyness, jealousy, guilt, shame, embarrassment.
Adults are skillful in accurately reading infants’ expressions.
However, adults are less accurate in discriminating infant’s negative facial expressions indicative of fear, anger, sadness or disgust. This appears not to be due to a lack of subtlety in young infants’ expression, but to the fact that the facial expressions arising from these different emotions are quite similar.
There is a biological basis for infant’s emotional facial expressions.
Multiple facial cues are used to signal emotion and the ability to convey and accurately interpret emotional expressions is impressively robust.
Infants indisputably display basic emotions very early in life. But there is considerable debate about when complex emotions emerge.
Infant discrimination of facial expressions
3-month-olds can distinguish between photographs of people smiling and frowning.
4- to 7-month-olds can distinguish between expressions of happiness and surprise.
Can young infants empathize with others’ emotions?
Very young infants may be emphasizing with the emotion they see portrayed.
But we cannot be sure.
Social referencing
Social referencing: infants and young children look at their caregiver for ‘advice’ when faced with an difficult or uncertain situation and seek social cures to guide their actions.
This provides and excellent way to assess infants’ understanding of other people’s emotional expressions.
Emotion understanding
Children begin to talk about emotions at a surprisingly young age, and parents readily give anecdotal accounts of their children using emotion words in the second year of life.
There are differences between emotional responses of infants and young children and those of older children and adults.
Emotional ambiguity: the realization that a person’s feelings may not be clear-cut or match your own emotional response.

Cognitive development
Epistemology: the study of the origins of knowledge and how we know what we know.
Two important findings of Piaget:
According to Piaget, everything that we know and understand is filtered through our current frame of reference. We construct new understandings of the world based on what we already know.
Constructivist.
Underlying structures and processes
Schemes
The basic unit of understanding is a scheme.
This is a cognitive structure that forms the basis of organizing actions and mental representations so that we can understand and act upon the environment.
This makes up our frames of reference through which we filter new information. Everything we know starts with the schemes we are born with.
Three of the basic schemes we are born with are reflexive actions that can be performed on objects: sucking, looking and grasping.
As children grow older they begin to use schemes based on internal mental representations rather than using schemes based on physical activity.
These schemes are operations.
Processes: organization and adaptation
Two innate processes to explain how children modify their schemes:
Through the processes of accommodation and assimilation we adjust to reality.
Piaget’s stages of cognitive development
Equilibration: in Piagetian theory, a state in which children’s schemes are in balance and undisturbed by conflict.
The processes of assimilation and accommodation comprise the equilibration process.
We are, by nature, constantly motivated to be able to fully assimilate and accommodate to objects and situations in our environment, to reach the state of cognitive equilibration.
At times, so many new levels of understanding converge that we reach a major reorganization in the structure of thinking.
These new levels of thinking are states. Qualitative shifts in a child’s way of thinking.
The ages at which they are achieved vary from one child to another. But, the order of progressing through stages is invariant.
Piaget believed his stages were universal:

The development of language
A communication system
Human language is primarily a communication system, a means for speakers of a language to communicate with one another.
This ability is not unique to the human species.
But non of the communication systems of other species have been found to possess all of he characteristics found in human communication.
Human language is a symbolic, rule-governed system that is both abstract and productive, characteristics that enable its speakers to produce and comprehend a wide range of utterances.
It evolved from multiple abilities.
A symbolic system
Words and parts of words represent meanings.
These symbols refer to things other than themselves. They are conventional because speakers of a language use the same word to express the same meanings. This makes communication possible.
Language symbols are arbitrary, there is no necessary relation between sound and meaning.
A rule-governed system
Each human language is constrained by a set of rules that reflects the regularities of the language.
The rule system is abstract, it goes beyond the simple association of individual words and instead involves the manipulation of abstract classes of words.
Articles precede nouns.
The abstract classes and rules enable a languages productivity.
Language is productive
A finite number of linguistic units and a finite number of rules are capable of yielding an infinite number of grammatical utterances.
Speakers may produce and comprehend novel utterances.
Language also makes it possible to discuss fantasies and hypothetical situations and events.
Turn-taking
Conversations take place when participants take turns responding to each other’s queries or statements.
Mother-infant interactions
Turn-taking behavior makes its first appearance in the earliest interaction between mothers and infants.
Nursing sometimes involves an early non-verbal type of turn-taking.
Touching and vocalizations are two modalities in which exchanges between mothers and their infants takes turns.
Proto-conversations: interactions between adults and infants in which the adults tend to vocalize when the infants are not vocalizing, or after the infant has finished vocalizing.
Between 8 and 12 months, infants begin to take a more active role in turn-taking.
The dyadic proto-conversations evolve into triadic interactions

Acquiring a theory of mind
Unlike other creatures, humans are able to marshal vast intellectual resources in an effort to connect with other people.
In non-humans, social behavior might have a great deal to do with instinct.
Early attunement to others’ minds
The ability to connect with other minds is present early in development.
Before long, the relationship is cemented when the baby shows a range of social responses.
Intuitive psychology: the awareness some people have regarding other’s desires, motives and beliefs, they appear able to anticipate others’ reactions and behavior.
Focusing on false beliefs: the unexpected transfer test
If we ask a participant to make judgments about another person’s true beliefs, they would respond correctly even in the absence of knowing anything about other minds.
Unexpected transfer test: a measure of theory of mind in which a child sees an object put in one place and it is later moved to another location without the child being aware of it. The theory-of-mind question is ‘where will the child look for the object when they want to find it?’
A reason for focusing on false beliefs is because it is important for children to be attuned to false as opposed to true beliefs.
Piaget characterized children below 7 years as egocentric.
But,
Wimmer found that from about 4 or 5 years, children set aside their own knowledge in making correct attributions of other people’s false beliefs.
Children negotiate a radical conceptual shift around the time of their fourth birthday, which equips them with a representational theory of mind that allows them to acknowledge false belief.
Children rapidly develop in their understanding of the mind at about 4 years of age.
The deceptive box test
According to Gopnik, understanding other minds by a process of simulation is implausible.
Being able to find out what someone else thinks by working out what you yourself would think in that situation depends

Reading and mathematics in developmental psychology
Introduction
Cultural tools: any tools that help us to calculate, produce models, make predictions and understand the word more fully.
One characteristic of cultural tools is that they can vary from culture to culture.
Orthography: a writing system. Orthography is used to describe any aspect of print, or, the spelling
Alphabetic script: a writing system in which written symbols (letters) correspond to spoken sounds. Individual phonemes represent the individual letters of an alphabetic script.
There are several different alphabetic scrips, and there are radical differences among orthographies that use exactly the same script.
Morpheme: a unit of meaning.
In some scripts, each character signals a morpheme.
Syllabary: the name given to a language that relies heavily on syllables for meaning.
Mora: a rhythmic unit in languages like Japanese that can be either a syllable or part of a syllable.
Syllable: the smallest unit of a word whose pronunciation forms a rhythmic break when spoken.
The difficulty of alphabetic scripts
Represents speech at the level of phonemes.
No language has many phonemes in it and thus one does not need many letters to represent them.
The problem
Phonemic awareness and learning to read
Children get better with phonemes as they grow older.
This has to do with instruction.
Experience of learning to read an alphabetic script does make people aware of phonemes. Children need this form of awareness to become successful readers.
Rhymes and rimes
Some research suggests that children’s awareness of other phonological units, beside phoneme, plays a part in learning to read.
Between the levels of the syllable and the phoneme lies a set of phonological units which is called intrasyllabic. These are usually smaller in size than the syllable and larger than the phoneme. (like onset and rime).
Onset: of a syllable is the consonant, cluster of consonants, or vowel at the beginning of a syllable.
Rime: the vowel sound of a syllable plus any consonants that follow.
Monosyllabic words rhyme because they have a rime in common. (cat and hat).
Most children are aware of rimes from an early age and often actively and spontaneously create, and play with,

Moral reasoning
Every discussion of the development of prosocial and antisocial behavior must cover the work of Piagent and Kohlberg.
Piaget
The first to study in a systematic way the moral judgments of children.
Piaget presented them with hypothetical moral dilemmas and then asked the children to make judgments.
From responses to dilemmas and to queries concerning the rules of games, Piaget concluded that younger children’s moral judgment was governed by unilateral respect for adult and adults’ rules, with little understanding of reciprocity or the intentions of others.
Young children children judge that the greater damage constitutes a larger moral violation, because the intentions will not be salient.
With age children develop a morality of cooperation and social exchange.
Children come to understand that intentions matter, that roles can be reversed, and that moral conflicts must be resolved through discussion and compromise with peers.
Age 10.
Kohlberg
Moral dilemmas to elicit moral reasoning.
Five stages of judgment
1. Heteronomous morality
2. Instrumental morality
3. Interpersonal normative morality
4. Social system morality
5. Human rights and social welfare morality
Age and stage
Kohlberg claimed that development across childhood and adolescence is characterized by sequential passage through the stages.
Stages 1 and 2 are most characteristic of children
Stage 3 emerging among adolescents.
Stage 4 increases in salience across adolescence
Stage 5 appears in adulthood

Cognitive development in adolescence
Perception
Perception is one of the cognitive abilities that develop earliest in life.
Children’s perception becomes increasingly flexible.
Ambiguous figures.
Increased flexibility of thought in adolescence allows alternations between the different perspecitves to be easily accomplished in ambiguous figures.
Adolescents can identify both components and wholes.
Selective attention
Development is evident in the adolescent’s superior ability to allocate attentional resources.
Selective attention.
the time it takes for the brain to either receive or output information.
It develops rapidly during childhood and continues to develop during the adolescent years so that older adolescents show faster speed of processing compared to younger adolescents.
This development is at least partially driven by the maturation of white matter in the brain.
By early adulthood memory can be quite remarkable.
There is a rapid development in face processing abilities during childhood and adolescence, with adult-level recognition reached by about 16 years of age.
Is there a qualitative change in face processing between childhood and adolescence?
Proposal
Encoding switch hypothesis: different information abut faces is represented in memory by children at different ages. Young children rely on information about individual features, whereas older children and adults use information bout the configuration of the features.
Face processing emphasizing features is referred to as featural processing.
Face processing emphasizing configuration is configural processing.
Children younger than 10 years of age make identifications largely on the basis of parahernalia items such as hat or glasses.
Younger children’s failure in recognizing the right person may be because they encoded non-essential information for determining identity.
Even face-processing abilities during adolescence are still developing considering their less than adult like levels in face recognition memory.
There is a drop in performance on face recognition tasks occuring at about 11 years of age.
This appears to be influenced by factors such as children’s level of familiarity with the type of face stimuli used and the difficulty of the recognition task.
Hormonal influence?

Educational implications
Pedagogy: an aspect of theory or practice related to learning.
Curriculum: the set of courses, and their content, offered at a school or university.
The effects of peer interaction
Piaget’s interest in interaction was predominantly in the importance of interaction with the physical rather than interpersonal environment.
In his earlier work, Piaget outlined a case for the importance of social interaction not only as a means to encourage learning, but also as a direct cause of development itself.
The primary intellectual deficit of the preoperational child, is the child’s inability to decentre or take account of alternative perspectives on the world to their own. However, this egocentrism could be overcome by peer interaction.
Through interaction with peers the child questions their own understanding, leading to a resolution of the conflict and a cognitive advantage.
Working in pairs can promote performance on Piagetian tasks
Peer facilitation effects: pairing of two children can have a positive impact on children’s later individual performance.
Bad performing children benefit from interaction.
Peer effects are persistent
The effects of paired interaction improve children’s performance are relatively long-lasting.
The changes in thinking promoted by sociocognitive conflict help children to benefit from subsequent learning experiences.
The positive and persistent effects of peer interaction extend beyond advances in cognitive development to advances in social development.
There is also concomitant development in social skills, communication, self-esteem, perspective-taking and social-emotional competence.
These positive effects on social skills are themselves a separate product of peer collaboration.
Peer effects in older children: Computer-based tasks
Much of the experimental work on the effects of peer interaction on children’s learning in middle school has centered on computer-based tasks.
7- 9 year olds benefit from interacting with other child when working on the Tower of Hanoi problem-solving task.
Peer interaction not only improved how quickly children arrived at the correct solution, but also positively affects the kind of strategies these children use.
Positive peer interaction effects are not restricted to very young children.
Constructing effective peer pairings
Positive effects of the efficacy of peer collaboration are not certain to arise.
Whilst a more developmentally advanced peer can likely benefit form collaboration in the form crystallizing and

Risk and resilience in development
Resilience: occurs when children experience positive outcomes despite experiencing significant risk.
The historical roots of resilience can be traced to research on individuals with psychopathology.
Many of the children with mental illness were doing well.
Risk factors includes:
Protective factor: anything that prevents or reduces vulnerability for the development of a disorder.
Vulnerability factors: those attributes of the individual that contribute to maladjustment under conditions of adversity.
Children’s exposure to risk varies according to age.
Children in the first few years of live are highly dependent on their families.
Adolescents have larger and more varied social communities and therefore may have access to supportive environments other than family. But they are more influenced by the loss and devastation involved with war and natural disasters.
Parental bereavement
One of the most immediately traumatizing events for children and adolescents is the death of a parent.
Parental bereavement represents a permanent loss and separation from a primary caregiver.
Can be aggraveted by additional stressors.
There is evidence that parental death typically has a smaller effect on children than the effect of parental divorce.
Parental separation/divorce and inter-parental conflict
Family dissolution from parental divorce increases children’s risk for psychological, behavioral, social and academic problems.
Children who grow up in single-parent homes are less successful on average.
These differences have been found to relate to a broad range of outcomes.
Risk is the greatest for children of divorced parents who experience:
Although the intensity diminishes over time, offspring of divorced and remarried families experience difficulties that extend into adolescence and young adulthood.
Children of divorced parents are more likely to have problems with family members, in intimate relations, in marriage, and in the workplace.
The divorce rate is higher and reports of general well-being and life satisfaction are

Social problems in schools
Social pressures in the classroom
One key factor is he process of social comparison whereby the child compares his or her performance with classmates.
Comparison is usually upward, with students who perform better than themselves but who seem similar to them on a rage of related and unrelated attributes.
Such comparison can raise the child’s level of academic performance but can also result in negative self-perceptions.
Self-worth protection: the tendency of some students to reduce their levels of effort so that any subsequent poor academic performance will be attributed to low motivation rather than a lack of ability.
Peer pressure to work, or not!
An important social factor in school concerns pressure to work, or not to work, hard in class and on homework.
There is a very different nature of peer pressure in Eastern and Western cultures.
In eastern cultures, striving is typically seen as praiseworthy.
Children in US and UK often discourage any overt display of academic engagement by their classmates. Academic success in itself is not necessarily problematic for acceptance. Effortless success is generally admired.
As high stakes testing in many countries increasingly lead teachers, parents and students focus upon success on a variety of externally regulated tests and examinations, it is not surprising that student stress levels on relation to academic performance can often be high.
Bullying is usually taken to be a subset of aggressive behavior, characterized by repetition and an imbalance of power.
The behavior is repetitive and the victim cannot defend him/herself easily, for one or more reasons.
Bullying is likely to have particular characteristics and particular outcomes.
The relative defenselessness of the victim implies an obligation on others to intervene.
How do we find out about bullying?
The main methods are:
Incidence figures for bullying
Incidence figures for bullying vary greatly depending on measurement criteria.
Broadly speaking, in Western industrialized countries, some 5 per cent of children might

Quantifying delay
Types of delay
Assessment of delay is not confined exclusively to norms for atypical development. Standardized assessment scales have been designed for use with specific exceptional populations.
The study of atypically developing children provides a profile of the main behaviors associated with a condition withing the context of development across the human lifespan.
This profile has the potential to generate a new knowledge base from which to design and deliver interventions.
Unfortunately, in the context of a relatively young field, there remains insufficient description of the atypical trajectories associated with particular disorders to warrant a sufficiently robust evidence base to inform the design and delivery of interventions fit-for-purpose.
Studying development that is considered atypical can inform us about development that is typical and vice versa.
