Chapter 12: Cognitive Development in Middle Childhood

Piaget's Theory: The Concrete Operational Stage - thought is more logical, flexible and organized that is was during early childhood

CLASSIFICATION: the ability to focus on relations between a general category and two specific categories

SERIATION: the ability to order items along a quantitative dimension, such as length and weight

REVERSIBILITY: the capacity to think through a series of steps and then mentally reverse direction, returning to the starting point

TRANSITIVE INFERENCE: the ability to seriate mentally

DECENTRATION: the ability to focus on several aspects of a problem and relate them rather than centering on just one aspect

Advances in spatial reasoning lead to the creation of COGNITIVE MAPS, which are mental representations of familiar large-scale spaces

Features of children's maps at each age

Ages 8-10: Better organized, shows landmarks along an organized route of travel, form an overall view of a large-scale space

Ages 10-12: Able to grasp scale (proportional relation between a space and its map representation)

Preschool: include landmarks, arrangement not always accurate, can only work if the map is rotated to a position other than orientation

Cultural variations: non-Western children have more intimate neighborhood knowledge showing a rich array of landmarks and aspects of social life. American kids draw more formal, extended space, with main streets and key directions by missing landmarks

Limitations of Concrete Operational Thought

Major limitation: children can only think in an organized, logical fashion ONLY when dealing with concrete information that they can perceive directly...work poorly with abstract ideas.

Major limitation: Kids do not come up with general logical principles that they apply to all relevant situations, children seem to work out the logic of each problem separately

Follow-Up Research on Concrete Operational Thought

How culture and schooling contribute to children's mastery of conservation and Piagetian tasks

Conservation is delayed in some cultures - taking part in relevant everyday activities helps children master conservation

Going to school increases mastery of Piagetian tasks where kids have opportunities to seriate objects, learn about order relations, and to remember the parts of complex problems

Case's information-processing view of cognitive development: With practice, cognitive schemes demand less attention about become more automatic, freeing up space in working memory, so children can focus on combining old schemes and generating new ones

CENTRAL CONCEPTUAL STRUCTURES: Networks of concepts and relations that permit one to think more effectively in a wide range of situations; emerge from integrating concrete operational schemes that result in increasingly complex, systematic reasoning

Reasons why children's understandings appear in specific situations at different times rather than being master all at once

Different forms of the same logical insight vary in their processing demands with those acquired later requiring increasing working memory

Child's experiences vary widely...children with relevant experiences will master tasks that are relevant

Information Processing: two factors that underlie every act of cognition are ATTENTION and MEMORY. Brain development causes changes to information processing because 1) increases in information-processing speed and capacity (due to myelination and synaptic pruning) and 2) gains in inhibition (ability to control internal and external distracting stimuli) is associated with PFC maturation

Attention

Changes during middle childhood

More adaptable

More planful

More selective

Order in which children acquire selective, adaptable, attentional strategies

  1. CONTROL DEFICIENCY - fail to control/execute strategies effectively
  1. UTILIZATION DEFICIENCY - use strategies, but not well
  1. PRODUCTION DEFICIENCY - fail to produce strategies when they could be helpful
  1. EFFECTIVE STRATEGY USE - use strategies consistently and performance increases

How do children typically learn planning skills and discuss what adults can do to foster it

A. Learn about planning by collaborating with more expert planners - organizing tasks, teacher's explanations of how to plan

B. Allowing children to do some planning in groups without being adult led so that kids have the opportunity to brainstorm and work out the details of the plans themselves

Children with ADHD

Typical characteristics of children with ADHD

Often hyperactive, exhausting parents and teachers and irritating others with their excessive motor activity

Typically perform lower on tests of intelligence

Low focus on tasks requiring mental effort; often act impulsively; ignoring social rules; lashing out with hostility when frustrated

Thought to be caused by deficient executive processing

Impairment in capacity to inhibit action in favor of thought, resulting in adequacy in self regulation and strategic thinking

Cluster of executive processing problems that interfere with ability to guide one's own behavior

Influences of heredity and environment on ADHD

Heredity - ADHD Is pretty heritable. Abnormal PFC activity, brains grow more slowly, smaller volume, thinner cerebral cortex

Environment - Prenatal teratogens linked to ADHD. More likely to come from homes with unhappy marriages and high family stress

Treatments for ADHD

Modeling and reinforcing appropriate academic and social behavior

Family interventions to ensure appropriate behavioral support

Stimulants - increase PFC activity

Memory Strategies

Memory strategies that emerge during middle childhood

REHEARSAL - repeating information to oneself

ORGANIZATION - grouping related items together

Factors required for perfecting memory strategies

Time

Effort

How is kids use of memory strategies adaptive

Tendency to experiment with many memory strategies is adaptive so that they can discover which ones work best and how to combine them effectively

ELABORATION: creating a relationship between 2 or more pieces of information not in the same category

Helps to combine items into meaningful chunks, permitting kids to hold onto much more information and to further expand working memory

GENERAL KNOWLEDGE: The more you know, the more you can organize information by rapidly associating new items with the things that you already knew.

MOTIVATION is the most important factor in children's memory processing as motivated kids acquire knowledge more quickly but also actively use what they know to add more

Cultural variation: no practical reason to use memory techniques

MIDDLE CHILDHOOD THEORY OF MIND

Older children see their mind as active - they know that focusing attention and effort leads to improving performance. They know that remembering is crucial for understanding and that understanding strengthens memory

Being able to make mental inferences helps to perspective taking: expands kids' their knowledge of false belief - enabling them to pinpoint the reasons that another person arrived at a certain belief, helping them understanding others' perspectives.

SECOND-ORDER FALSE BELIEFS: one character's belief about a second character's belief in a complex story

Appreciation of second order false beliefs enables kids to pinpoint the reasons that another person arrived at a certain belief; assisting them greatly in understanding others' perspectives

Teachers call attention to the workings of the mind when they remind children to pay attention, remember mental steps, share points of view, with peers, and evaluate their own and others' reasoning

Cognitive Self-Regulation: the process of continuously monitoring progress toward a goal, checking outcomes and redirecting unsuccessful efforts; researchers study it by measuring the impact of children's awareness of memory strategies on how well they remember.

School age children are not good at cognitive self-regulation - they know about strategies but they do not always apply them effectively or use them at all.

Beings to develop gradually in middle childhood. It is cognitively demanding, so if they encounter problems, they will take steps to address them. Passivity is associated with poor student achievement

Adults can foster self-regulation skills: pointing out important features of a task, suggest strategies on how to approach problems and monitoring their own performance

ACADEMIC SELF-EFFICACY: confidence in their ability, which supports future self-regulation; based on the acquisition of effective self-regulatory skills

Applications of Information Processing to Academic Learning

Information processing skills associated with reading

Recognize appearance of common words

Hold chunks of texts in working memory

Translation of letters into speech sounds

Combine parts of text into an understandable whole

Perception of single letters/letter combinations

Approaches to learning how to read

WHOLE LANGUAGE APPROACH: being exposed to text will motivate kids to discover the skills they need to read

PHONICS APPROACH: children must learn basic rules for translating written symbols into sounds, and only after mastering these skills should they get complex reading material

Combination of both approaches is optimal: learning phonics helps kids to decode words they have never seen before; detecting new letter-sound relations while reading on their own and as their fluency in decoding words increase, they are freer to attend to text meaning

Reading skill development

7-8 years: masters basic decoding skills, reads about 3000 words

9-14 years: reads to learn new knowledge

6-7 years: masters letter-sound correspondences, reads simple stories

15-17 years: reads widely, taps material with diverse viewpoints

2-6 years: pretends to read and write

18 years and older: reads with self-defined purpose

Mathematics instruction

click to edit

Controversy between use of drill in computing vs number sense (conceptual understanding): balance is usually best

Why are Asian students better at math? There is a consistent structure of number words; use of the metric system, short words - more can be held in working memory; extensive everyday practice in counting and computation; more time exploring math concepts in school rather than on drilling

INDIVIDUAL DIFFERENCES IN MENTAL DEVELOPMENT

Types of items included on intelligence tests for children: vocabulary, general information, verbal comprehension, block design, picture concepts, spatial visualization, digit span, letter # correspondence, symbol search

Differences in IQ test administration

GROUP ADMINISTERED: large #s of students tested; screen to see who needs more evaluation; useful for instructional planning; can be given by teachers will little training

INDIVIDUALLY ADMINISTERED: increased amount of time; 1:1 evaluation; to give tests requires considerable training and experience; look at behavior as well as answers

Most common intelligence tests

Weschler Intelligence Scale for Children - IV: appropriate for individuals for ages 6-16, assesses four broad intellectual factors - verbal reasoning, perceptual reasoning, working memory, and processing speed, first test to be standardized on samples representing the total population of the US, including ethnic minorities

Weschler Preschool and Primary Scale of Intelligence - Revised: appropriate for children 2 years 6 months through 7 years 3 months

Stanford-Binet Intelligence Scales: appropriate for individuals between 2 years of age and adulthood, assesses five broad intellectual factors - general knowledge, quantitative reasoning, visual-spatial processing, working memory, and basic information processing

Recent Efforts to Define Intelligence: Factors that are important in predicting IQ - efficient thinking, processing speed, working memory capacity, flexible attention, memory, reasoning strategies

COMPUTATIONAL ANALYSIS: looking for relationships between aspects or components of information processing and children's intelligence test scores

Identifying the processing skills that test poorly will give us information about how to intervene

Major shortcoming: It regards intelligence as entirely due to causes within the child disregards how cultural and situational factors affect children's thinking

STERNBERG'S TRIARCHIC THEORY OF SUCCESSFUL INTELLIGENCE: emphasize the complexity of intelligent behavior, when IQ tests can overlook intellectual strengths of children

CREATIVE INTELLIGENCE: think more skillfully than others when faced with novelty

PRACTICAL INTELLIGENCE: ability to adapt to, shape or select environments

ANALYTICAL INTELLIGENCE: the information processing strategies that underlie all intelligent acts, such as, applying strategies, self-regulation, acquiring task-relevant and cognitive knowledge

GARDER'S THEORY OF MULTIPLE INTELLIGENCES: defines intelligence in terms of distinct sets of processing operations that permit individuals to engage in a wide range of culturally valued activities; not grounded in research

Spatial

Bodily-kinesthetic

Musical

Naturalist

Logico-mathematical

Interpersonal

Linguistic

Intrapersonal

Primarily influenced by cultural values and learning opportunities

EMOTIONAL INTELLIGENCE: refers to a set of emotional abilities that enable individuals to process and adapt to emotional information; measured by devising items that tap emotional skills that enable people to manage their own emotions and interact competently with others

Modestly related to IQ, positively associate with self-esteem, empathy, prosocial behavior and life satisfaction

How to foster emotional intelligence: teach emotional understanding, respect and caring for others, strategies for regulating emotion, resistance to unfavorable peer pressure, using active learning techniques that provide skill practice in and out of the classroom

Explaining individual and group differences in IQ

SES differences: middle-SES kids outperform low-SES kids by an average of 9 points. When SES is matched, difference in black-white kids is discovered by 1/3

Ethnic differences: black kids score 10-12 points below, Hispanic kids score 5-7 points below white average

Kinship studies and role of heredity in IQ: IQs of identical twins are more similar than those of fraternal twins, leading researchers to believe that heredity counts for 50% of IQ. Heritability of children's intelligence rises with parental education and income-conditions tat enable kids to realize their genetic potential

Adoption studies and contribution of environmental factors in IQ: IQs of adopted kids increased compared with IQs of nonadopted children remaining in deprived families. Children of the low-IQ biological mother scored above average in IQ if they were adopted by a mum with above average IQ.

Increase in IQ tests scores with each generation: Generational rise in average IQ, supporting idea of importance of role of environmental factors - increased quality of nutrition and education, technological advances and an increase in cognitively demanding leisure activities.

TEST BIAS: occurs when a test samples knowledge/skills that not everyone has learned or if the testing situation favors performance of some groups.

Controversy around this: If IQ represents success in a culture, it is really biased? Lack of exposure to knowledge and communication styles, negative stereotypes can undermine children's performance

Ethnic minority parents without extensive schooling prefer a COLLABORATIVE style of communication. With increasing education, parents establish a HIERARCHICAL stype.

Using nonverbal IQ tests does NOT raise the scores of ethnic minority children - they grow up in less "object-oriented" families, lacking opportunities to use games and objects that promote certain intellectual skills

STEREOTYPE THREAT: the fear of being judged on the basis of a negative stereotype can trigger anxiety that interferes with performance

Kids end up with decreased motivation via self-protective disengagement sparked by stereotype threat that causes students to devalue doing well in school

Two components of self-discipline that predict school performance

Effort

Delay of gratification

Reducing Cultural Bias in Testing

ADAPTIVE BEHAVIOR: ability to cope with the demands of their everyday environments

Often used in combination with IQ to determine if students need special education support

DYNAMIC ASSESSMENT: pretest-intervene-rest; adult introduces purposeful teaching into testing situation to find out what the child can attain with social support; not proven effective but individualized assistance on tasks carefully selected to help the child move beyond their current level of development

LANGUAGE DEVELOPMENT

METALINGUISTIC AWARENESS - ability to think about language as a system

Vocabulary: rate of vocab growth is highest - kids learn about 20 new words per day

Strategies that assist school-age children in building vocab

Figure out word meanings from context

Benefit from conversations with more expert speakers

Analyze structure of complex workds

Reading offers exposure to more diverse and complex vocabulary

New gains: use words more precisely, explanations of categorical relationships, use of synonyms, appreciate multiple meanings of words, riddles and puns are understood

Grammar - two achievements of middle childhood - use of the passive voice more frequently and advanced understanding of infinitive phrases

Pragmatics

Advances in pragmatic speech

Increase in ability to evaluate clarity of others' messages and better at resolving inconsistencies

More sensitive to distinctions between what people say and what they mean

Better at adapting to the needs of listeners in challenging communicative situations

Cultural differences in children's narrative

African American kids - use a topic-associating style in which they blend several similar experiences

American kids - topic focused style of describing an experience from beginning to end

Learning Two Languages

Two ways in which children become bilingual

Acquiring both languages at the same time in early childhood

By learning a 2nd language after mastering the first

Sensitive period for 2nd language development exists but a cutoff for 2nd language learning has not been identified

Cognitive benefits of bilingualism: denser grey matter in left hemisphere areas devoted to language; increased selective attention, analytical reasoning, concept formation, cognitive flexibility, metalinguistic awareness, reading achievement

Canada's Language Immersion Programs: English speaking kids are taught entirely in French for several years across all subject areas

American bilingual education - two streams

Time communicating in a kid's native tongue decreases English language achievement

Must develop native languages to show respect for kid's heritage and prevents inadequate proficiency in both languages

Increased engagement and participation

Quicker acquistion of 2nd langauge

Children's Learning in School

Characteristics of high-quality education in elementary school

Physical setting

Integrated and rigorous curriculum

Class size (no larger than 18 children)

Relationships with parents

Reasons why small class sizes are beneficial

Less time disciplining, more time teaching and giving individual attention

Better concentration, higher-quality class participation, more favorable attitudes towards school

Educational Philosophies

Constructivist Classrooms: Teacher acts as a guide and support in response to needs of kids; students evaluated by their progress; children are active agents who reflect on and coordinate their own thoughts rather than absorbing those of others; associated with gains in critical thinking, social and moral maturity, and positive attitudes

Traditional Classrooms: teacher is authority for all knowledge, rules and decision making and does most of the talking. Students are passive and follow direction of teacher. Progress is evaluated by how well they keep pace to a uniform set of standards for their grade.

Nature of social-constructivist classrooms: teachers and students working together; as children appropriate the knowledge and strategies generated through working together they become competent, contributing members of their classroom and increase in cognitive and social development

Vygotskian inspired teaching methods

Communities of learners: teachers guide overall process of learning but no other distinction is made between adult and child contributors - all participate, define and resolve problems.

Teaching adapted to students' ZPD

Reciprocal teaching: refers to a method of learning in which a teacher and 2-4 students form a cooperative group and take turns leading dialogues on the content of a text passage

Cognitive strategies group members apply during these dialogues

Summarizing the passage

Discuss the summary and clarifying unfamiliar ideas

Asking questions about the content of the text passage

Predicting upcoming content based on clues in the passages

Based on assumption that different people have different expertise that can benefit the community and that students can be experts too

Teacher-student interaction

High-achieving, well behaved students: receive increased support and praise from their teachers

Low-achieving, disruptive students: receive more conflicts and criticism from their teachers

EDUCATIONAL SELF-FULFILLING PROPHECIES: children may adopt teachers' positive or negative views and start to live up to them; effects on kids - decreased achievement, respond with intense anxiety and reduced motivation

Grouping Practices

HOMOGENEOUS GROUPS: where children of similar ability are taught together; get more drill and kill, engage in less discussion and progress at a slower pace, Can lead to decrease in self-esteem and motivation

COOPERATIVE LEARNING: multigrade classrooms

Benefits: Increased academic achievement and self esteem, positive attitudes towards school, harmony, decreased competition

Computers and Academic Learning: use a computer for 30 minutes for schoolwork, and 1 hour per day for pleasure

Use of word-processing programs: write freely, experimenting without worrying about handwriting, easily revised (less worried about mistakes), projects tend to be longer and of a higher quality

Gender differences in computer use and choice of activities

Boys: downloading, trading/selling, creating webpages, writing computer programs, data analysis, use spreadsheets

Girls: information gathering, instant messaging

Teaching Children with Special Needs

INCLUSIVE CLASSROOM: where students with learning difficulties learn alongside typical students in their regular educational setting for part or all of the school day - designed to promote participation in society and to combat prejudices against individuals with disabilities

Kids with learning disabilities: 5-10% of school age children, have considerable difficulty with one or more aspects of learning. Achievement is considerably behind what would be predicted on basis of IQ.

Kids with mild mental retardation: IQ between 55-70, also show problems with adaptive behavior

Achievement gains depend on disability severity and the support services available - may be overwhelmed by their peers; best practice is half in, half out programming

Promoting peer acceptance in inclusive classrooms

Promote positive peer relations - cooperative learning, peer tutoring

Fostering emotional sensitivity and prosocial behavior

Gifted children - IQ scores above 130, have keen memories and an exceptional capacity to solve challenging academic problems

CREATIVITY - refers to the ability to produce work that is original yet appropriate

CONVERGENT THINKING: involves arriving at a single correct answer - type of thinking emphasized on IQ tests

DIVERGENT THINKNG: generation of multiple and unusual possibilities when faced with a task or problem

TALENT - refers to outstanding performance in a particular field

Family characteristics that foster talent: warm and sensitive parents; providing a stimulating home life; devoted to developing child's abilities; provide models of hard work and high achievement; reasonable demands; arrange for appropriate tutelage

Risk factors associated with giftedness: social isolation, hiding of their abilities to better relate to peers, girls report low self-esteem and depression

Models for educating gifted children

Pull children out for special instruction

Advance to a higher grade

Providing enrichment in regular classrooms

How Well-Educated are US Children? - most American parents and teachers believe innate ability is more important than hard work when it comes to academic success

Why do US children lag behind kids from other countries?

Less equitable in quality of education provided

Teachers have large variation in training, salaries and teaching conditions

Instruction is less challenging

Why is Finland recognized for having such a good educational system?

Abandoned national testing system and replaced it with high-quality national curriculum

Teachers are highly trained

Education is grounded in equal opportunity for all

Strategies for improving the US education system

Supporting parents

Investing in high quality preschool education, so everyone is ready to learn

Strengthening teacher education

Pursuing school improvements that reduce the large inequities in quality of education between SES and ethnic groups

Providing challenging, relevant instruction with real-world applications
