Developmental psychology
Chapter 11
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.
Meta-cognition: knowledge of one’s state of mind, reflective access to one’s cognitive abilities, thinking about how one is feeling or thinking.
Gopnik found that children below 4 years of age have just as much difficulty accessing their own states of belief as they have in estimating another person’s.
Deceptive box task: in which a child sees that a box (usually of a well-known brand of sweets/candy) which they thought contained sweets/ candy actually contains pencils, and when asked, ‘What did you originally think was in the box?’ children under age of 4 will typically say ‘pencils’.
Children who correctly recalled their prior false belief, tended to be the same who judged correctly that someone else could have a false belief.
Gopnik argued that whether or not children could imagine what they would think in a different situation was not the issue. If children do not know their own mind, they cannot use insights into their own mind as a basis for working out what another person thinks.
Accordingly, their difficulty in understanding the mind seems to lie at a more fundamental level.
Gopnik suggests that children have to acquire a naive theory of the mind, a theory which gives access to their own states of belief as well as other people’s.
Some argue that there is a developmental stage in the sense that children move onto a radically different level of understanding at about 4 years of age once they acquire the principles for explaining and predicting other people’s behavior.
The case for gradual change
Evidence which suggests that children younger than 4 years might be capable of acknowledging false belief and also that sometimes older individuals, including adults, make systematic errors when trying to infer what another person is thinking.
The assumption is that gradual changes that occur with development improve the probability that the child will give a correct judgment, but this also depends on task demands.
Do children suddenly begin giving correct judgments of false belief?
When performing on a test of false belief, you an either answer correctly or incorrectly. The test is incapable of detecting degrees of performance that fall somewhere in between.
We should enquire focusing on the probability of the child passing the test at any given time. It might become apparent that the probability increases gradually between 3 and 5 years of age.
Data reported by Gopnik suggests that children are variable in their performance at about 4 years of age.
There were many instances of children passing one test of false belief and failing another.
Giving a correct judgment in a test of false belief does not guarantee future success.
Longitudinal studies indicate that the number of false belief tests that a child is likely to pass increases very gradually with age.
There is a possibility that 3-year-old children are capable of the same kind of processing as older children when it comes to working out what other people might be thinking, but tend to make errors in performance of task.
We need to recognize a distinction
If younger children engaged in the same kind of processing then a clue to this effect might apparent in how long they take to respond to the question about another person’s belief.
Kikuno found that children aged 3 and 4 years tended take longer to answer questions about another person’s false belief than they took to answer questions about the true state of reality.
Apparently, the children had not worked out what the protagonist was thinking automatically and only began to do that when promoted by the test question.
Kinkuno found that children took as long to reply to a question about the protagonist’s belief whether their answer was correct or incorrect.
These findings are consistent with the possibility that children engage in the same kind of processing irrespective of whether they got the answer right or wrong.
Seemingly, the younger children differed form older ones not in their level of competence, but in being more prone to errors in performance.
Understanding the question asked
Children might not differ from each other in how they understand the mind, they might differ drastically in how they interpret questions.
The younger children might not be clear on the point in time the question refers to.
A modified question gives children a better change of answering right.
Evidence seems to suggest that performance factors might mask early signs of competence in very young children’s understanding of other people’s minds.
Children below 3 years might understand that minds hold beliefs about the world, among other things, they do not always demonstrate this level of competence under certain test conditions, perhaps because they have to remember too much of the information in the stories that are typically used.
Children as young as 15 months showed signs of understanding false belief in a preferential looking procedure involving violation of expectation.
There is evidence that adults sometimes have difficulty acknowledging false belief.
Hindsight bias: the inclination to see events that have already happened as being more predictable than they were before they took place.
There is a possibility that people do not automatically attune to other people’s beliefs.
Adult participants took longer to respond to a question about a protagonist’s false belief than they took to respond to a question about the true state of reality.
It seems like that while participants could easily work out what a protagonist was thinking, this is something that they did not do automatically.
Nature versus nurture
When making judgments about beliefs, we need to resist the lure of current reality and we must not fall victim to the hindsight bias.
The ability to do this is not all or nothing. Success is more common among older participants.
It seems that subtle differences in how people understand others’ mind can vary between cultures.
Collectivistic versus individualistic.
It seems that cultural values can impact upon one’s level of trust in others which in turn perhaps impacts on how one evaluates what other people are thinking.
Are we equipped with a dedicated module in he brain for understanding other minds?
Modularity: the view that we have separate modules for different abilities.
Fordor suggestion: module is demonstrably active at a younger age in tasks that have a different form from the standard test of false belief, although supporting evidence for his specific predictions is somewhat scant.
Normally developed young children possess the relevant module but at 3 years of age are yet to acquire the general processing skills to give a correct judgment in any task that had the form of a test of false belief.
The problem is the form of the problems makes demands on processing that are beyond the performance abilities of a typical 3 year old.
This can even be if it is not a mind-related task.
So long as children could acknowledge a counterfactual state, they had no further difficulty in identifying this as a false belief held by another person.
The evidence suggests that whether or not children succeed in acknowledging false belief depends on more than the activity of a special brain module dedicated to the task. Children with autism might have a more specific difficulty with false belief that is associated with their difficulty connecting to other people.
The main problem with modularity account is that it implies that calculating what other people think is something we do automatically, but this seems not to be the case. Also, cultural influences.
The role of the family: siblings
Variations are also apparent across different kinds of family.
A child with many siblings would encounter the potentially beneficial experience of exposure to other points of view. But this might be a socially uncomfortable or even annoying experience. It could have cognitively beneficial spin-offs in terms of becoming better with other minds.
But perhaps children become attuned to other minds not through the experience of a clash of perspectives with siblings, but by being formally tutored about the mind by wiser individuals. The potentially beneficial adult input can be defined in large families. With the consequence that each child would not be receiving the optimum level of tutoring about the mind.
The number of siblings correlates negatively with the child’s intelligence quotient score, as does birth order. These birth order IQ differences are very small.
Zajonc suggests that intellectual development depends partly on beneficial parental input.
Children aged 3 years who had siblings were more likely to pass a test of false belief.
Those with several siblings stood a better change of giving a correct judgment than those with just one or two siblings. But only those with older siblings.
The role of family: adults
Adults who are mind minded are beneficial for children’s knowledge of false belief.
The characteristics of the child
The characteristics of the child and the environment probably interact in complex ways with respect to the influence they have on development.
The characteristics of the child are likely to shape the way people respond to them, which in turn will impact upon the extent to which social input is beneficial.
Wing’s trait of impairments: impairments of:
Lack of imagination
The lack of imagination is manifest in many ways. Notably in pretend play.
Leslie suggested that the kind of mental processing require for pretense is the same as that needed to understand states of belief.
A person who did not have the ability to disengage form reality in pretense probability would not be able to disengage from reality in order to acknowledge a false belief.
Individuals with autism have difficulty with pretence is in itself a striking clue to the possibility that they might be unable to attune to other minds.
Socialization and communication
Underdevelopment in socialization and communication also point to an underlying deficiency in understanding other minds.
Social skill depends on being able to diagnose other people’s sensitivities, attitudes and knowledge.
Causes of autism
At least one of the causes of autism has genetic origin.
Other causes arise form accidental injury or virus infection. These various factors could lead to an abnormality in the brain that forms the neurological seat of autism.
Failure to understand the mind
There are reasons for thinking that children with autism might be delayed in developing and understanding of the mind.
Evidence:
It is invalid to argue that autism is the product of a failure to understand the mind as defined by inability to acknowledge beliefs.
Nonetheless, individuals with autism are likely to be developmentally delayed.
Verbal mental age is a good predictor of whether or not a person with autism will succeed in acknowledging false belief, but is seems that verbal mental age has to be substantially higher in autism than in typically developing children.
For false belief, it seems a minimal verbal mental age of 7 years is often required in autistic development.
By the time most people become adults they will have acquired a highly developed ability to make psychological inferences about other people, even if their mental processes are subject to bias.

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.
Designs for studying age-related changes

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

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.

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

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.

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

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

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

Atypical development
Two ways in which development can be atypical

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.
