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 a result of their cognitive adaptations they become better able to understand the world.
Cognitive adaptations: children’s developing cognitive awareness of the world.
An organismic world view.
Adaptation: assimilation and accommodation
In order to adapt to the world two important processes are necessary:
Schemas: mental structures in the child’s thinking that provide representations and plans for enacting behaviors.
Assimilation and accommodation always occur together during infancy.
Throughout life the processes of assimilation and accommodation are always active as we constantly strive to adapt to the world we encounter.
These processes are functional invariants (processes that do not change during development). What do change are the cognitive structures (schemas) that allow the child to comprehend the world at progressively different levels of understanding.
Four stages of cognitive development
Children move through four broad stages of development, each of which is characterized by qualitatively different ways of thinking.
Sensorimotor stage (birth to 2 years)
The child changes from the helpless newborn to the thinking and knowing toddler. These changes take place as a result of the infant’s actions on the objects and people in its environments.
Thought is based primarily on perception and action. Internalized thinking is largely absent.
Preoperational stage (2 to 7 years)
Children can solve a number of practical, concrete problems and they can communicate well and represent information and ideas by means of symbols.
Children are unable to coordinate aspects of problems in order to solve them.
Children tend to be egocentric.
Children display animism in their thinking (they tend to attribute life and life-like qualities to inanimate objects, particularly those that move and are active).
What underlies children’s thinking during the preoperational stage is the lack of a logical framework.
Concrete operations stage (7 to 11 years)
Reasoning is more logical, systematic and rational in its application to concrete objects.
Centration: the focusing or centring of attention on one aspect of a situation to the exclusion of others.
Conservation tasks. Tasks that examine children’s ability to understand that physical attributes of objects do not vary when the object changes shape.
The formal operations stage (from about 11 years)
The individual acquires the capacity for abstract scientific thought. This includes the ability to theorize about impossible events and items.
Information processing: the view that cognitive processes are explained in terms of inputs and outputs and that the human mind is a system through which information flows.
An organism’s behavior cannot be understood without knowing the structure of the perceiver’s environment.
Constructivism: Perception fills in information that cannot be seen or heard directly.
Piaget’s theoretical view that infants are not born with knowledge about the world, but instead gradually construct knowledge and the ability to represent reality mentally.
Information processing theories focuses on the information available in the external environment, and the means by which the child receives and interprets this information.
Cognitive development in infancy
(According to the information processing approach) cognitive development proceeds in bottom up fashion, beginning with the ‘input’ or uptake of information by the child, and building complex systems of knowledge from simpler origins.
For young infants, sensory and perceptual skills are relatively immature, and this may impose limits on knowledge acquisition.
Cognitive development in childhood
In childhood, the task of building knowledge often comes down to determining which of the many ‘strategies’ are available to solve particular problems.
Children have incorporation of new strategies, identification of efficient strategies, more efficient execution of each strategy and more adaptive choices among strategies.
Children typically use multiple strategies at all points of assessment. Children hone their choices with experience and thus come to solve problems more quickly and accurately.
Connectionism and brain development
Information processing theory takes advantage of two new advances in cognitive science
Comparing information-processing approaches with Piaget’s approach
In common:
Different:
Vygotsky
One of the first to recognize the importance of knowledgeable adults in the child’s development.
The development of intellectual abilities is influenced by a didactic relationship with more advanced individuals.
Higher mental abilities are first encountered and used competently in social interactions, only later being internalized and possessed as individual thought processes.
Social interaction plays a fundamental role in cognitive development.
There is a gap between what the child knows and what they can be taught.
At a given stage of development the child has a certain level of understanding, a temporary maximum. A little beyond this point lies the zone of proximal development (ZPD). This is the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined though problem solving under adult guidance or in collaboration with more able peers.
Behaviorism and social learning theory
Early behaviorism
Law of effect: the likelihood of an action being repeated is increased if it leads to a pleasant outcome, and decreased if it leads to an unpleasant outcome.
Early behaviorists’ view of child development.
The infant is born with little more than the machinery of conditioning and infancy and childhood consists of constant warping and molding under pressure of the environment. The child is passive and receptive and can be shaped in any direction.
Any behaviors are towers built upon the foundations of very simple, repeated connections between stimuli and its response.
B.F. Skinner’s behaviorism
Operant conditioning
Social learning theory
The application of behaviorism to social and cognitive learning that emphasizes the importance of observational learning.
Social cognitive theory: emphasizes social factors in cognitive development.
Ethological approaches: emphasize the evolutionary origins of many behaviors that are important for survival (like imprinting).
The ethological approach
Certain behaviors in the young of many species would be genetic in origin because:
Two implications of ethology’s conception of behaviors:
Attachment theory – John Bowlby and Mary Ainsworth
The need for attachment is a primary drive (basic needs).
Monotropy: the view that the infant has a basic need to form an attachment with one significant person.
But, infants often form multiple attachments. And in some cases their strongest attachments was to people who did not fulfill basic cargiving activities, but who did engage in satisfying interactions with them.
Bowlby believed that the attachment system between infant and caregiver became organized and consolidated in the second half of the infant’s first year from birth, and became particularly apparent when the infant began to craw.
Sigmund Freud, the founder of psychoanalysis
Much of our behavior is determined by unconscious forces of which we are not aware.
Psychoanalytic theory: there are three main personality structures:
the ego and the superego develop as the individual progresses through the five psychosexual stages.
The five spychosexual stages
Oral stage (birth to 1 year)
The infants greatest satisfaction is derived form stimulation of the lips, tongue and mouth.
Sucking is the chief source of pleasure for the young infant.
Anal stage (1 to 3 years)
Toilet training takes place and the child gains the greatest psychosexual pleasure from exercising control over the anus and by training and eliminating faeces.
Phallic stage (3 to 6 years)
Children obtain their greatest pleasure form stimulating the genitals.
(At this time boys experience the Oedipus complex). When the boy realizes that his father is a major competitor for her (sexual) affections, he fears that castration at the hands of his father (castration complex). In order to resolve this complex he adopts the ideals of this father and the superego develops.
Electra complex (is the Oedipus complex for girls). It is the same.
Latency and genital stages (6 to adolescence)
From around 6 years the torments of infancy and early childhood subside and the child’s sexual awakening goes into a resting period.
Then, at adolescence, sexual feelings become more apparent and urgent and the genital stage appears. In the latter ‘true’ sexual feelings emerge and the adolescent strives to cope with awakening desires.
Problems with Freudian theory
Unconscious processes are almost impossible to test.
Psychoanalysis, then and now
Freudian theory has been of immense importance in pointing out two possibilities:
Humanistic theories focus on the individual’s own subjective experiences, motives and desires.
Emphasizes that humans have free will and are motivated to fulfill their potential.
We are not driven by unconscious needs, neither are we driven by external environmental pulls such as reinforcement and rewards.
Self-actualization: fulfillment of needs beyond those deemed necessary for survival.
Abraham Maslow’s hierarchy of needs
There is a hierarchy of needs or motives that determine behavior.
Nature-nurture
Whether development is the result of an individual’s genes or the kinds of experiences they have throughout life.
Stability versus change
Whether individuals are stable in the sense of maintaining their rank order across age.
Continuity versus discontinuity
Whether development is continuous or discontinuous.

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.

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 layer of identical cells in the wall of the neural tube.

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.

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.
Emotion understanding tasks
There are links between young children’s task-based

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
Proto-imperatives: when infants point to an object and then alternate

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 on having reflective access to your own states of mind.

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, rhymes.
Children’s scores in rhyme oddity tasks predicted their success

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 although even then it remains fairly rare.

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?
Short-term memory
Short-term memory increases steadily throughout childhood and into adolescence.

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 communicating their own thinking, it is not always the case that the

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 lower.
Resilience is the normative outcome for children who are faced

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 be seen as regular or severe bullies, and some 10 per cent

Atypical development
Two ways in which development can be atypical
Williams syndrome: a rare neurodevelopmental disorder caused by deletion of about 26 genes from the long arm of chromosome 7.
Considering whether a child development is
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.
Which of the following statements about development in puberty is true?
A developmental psychologist carries out research into the development of aggression in children. She registers the same group of children at several moments and has chosen a research design in which she can both identify possible cohort effects and correct them in her analyzes. What is the design of this researcher?
Berk typifies developmental psychological theories as theories that view development as discontinuous or continuous. In which following combination of two developmental psychological theories is first called a discontinuous development theory and then a continuous development theory?
Jorrin is 3 years old and is asked to arrange a group of 7 blocks from small to large. Completing this task requires __________ and Jorrin will probably _________ be able to complete the task.
In developmental psychology, a "sensitive period" refers to:
