Human Growth and Development Chapter Nine The Play Years: Cognitive Development PowerPoints prepared by Cathie Robertson, Grossmont College Revised by Jenni Fauchier, Metropolitan Community College How Young Children Think: Piaget and Vygotsky • Piaget—Swiss developmentalist – believed young children were limited by their egocentric perspective • egocentrism—Piaget’s term for type of centration in which child sees world solely from his/her personal perspective • Vygotsky—Russian developmentalist – recognized how child’s social/cultural context helps shape his/her cognitive development Piaget: Preoperational Thought • Preoperational thought—Piaget’s term for cognitive development between 2 and 6 years – characterized by centration, focus on appearance, static reasoning, and irreversibility Obstacles to Logical Operations • Centration—tendency to focus on one aspect of a situation • Egocentrism or ego-centration— contemplation of the world exclusively from child’s personal perspective – empathy is an exception Obstacles to Logical Operations, cont. • Focus on appearance—ignores all attributes except appearance • Static reasoning—assumes that the world is unchanging • Irreversibility—fails to recognize that reversing a process can sometimes restore whatever existed before transformation Conservation and Logic • Thinking is intuitive rather than logical • Conservation—principle that amount of substance is unaffected by changes in appearance – applied to liquids, numbers, matter, length – understanding develops after age 7, and then slowly and unevenly Conservation and Logic, cont. Vygotsky: Children as Apprentices • One Theory – theory-theory—Gopnik’s term for the idea that children attempt to construct a theory to explain everything they see and hear • Children do not strive alone; their efforts are embedded in social context – parents guide young children’s cognitive growth in many ways • present new challenges for learning • offer assistance and instruction • encourage interest and motivation • Apprentice in thinking—child whose intellectual growth is stimulated and directed by older and more skilled members of society • Guided participation—process by which young children, with the help of mentors, learn to think by having social experiences and by exploring their universe How to Solve a Puzzle • Guidance and motivation – structure task to make solution more attainable – provide motivation • Guided participation – partners (tutor and child) interact – tutor sensitive and responsive to needs of child – eventually, because of such mutuality, child able to succeed independently Scaffolding • Scaffolding—sensitive structuring of child’s participation in learning encounters • Zone of proximal development (ZPD)— skills too difficult for child to perform alone but that can be performed with guidance and assistance of adults or more skilled children – lower limit of ZPD can be reached independently – upper limit of ZPD can be reached with assistance – ZPD is a measure of learning potential Scaffolding, cont. • Private speech—internal dialogue when people talk to themselves through which new ideas are developed and reinforced – verbal interaction is a cognitive tool • Social mediation—use of speech to bridge gap between child’s current understanding and what is almost understood Theory of Mind • We each have our own personal understanding of human mental processes, and child develops this too – complex interaction of human mental processes • emotions • thoughts • perceptions • actions Emergence by Age 4 • Social referencing • Sudden understanding that mental phenomena may not reflect reality – people can be deliberately deceived or fooled Contextual Influences on Theory of Mind • • • • Brain maturation (prefrontal cortex) General language ability An older sibling Culture that anticipates the future Language • Emergent literacy—skills needed to learn to read • Is early childhood a sensitive or a critical period for language development? – ages 2 to 6 do seem to be a sensitive period—a time when a certain type of development (in this case, emergent literacy) occurs most rapidly Vocabulary • 2 to 6 olds learn average of 10 words per day • Fast mapping—speedy and not precise way a child assimilates new words by mentally “charting” them into interconnected categories – logical extension, or application of newly learned word to other unnamed objects in same category, closely related to fast mapping – fast mapping aided by the way adults label new things for children • Fast mapping, cont. – children use basic assumptions about syntax and reference to fast map – children cannot comprehend every word they hear – difficulties may occur • with words expressing comparisons • with words expressing relationships of time and place Grammar • The grammar of a language includes the structures, techniques, and rules used to communicate meaning • Young children learn grammar so well they tend to apply its rules when they should not, a tendency called overregularization – examples: plural nouns (“foots”), past tense (“breaked the glass”) Learning Two Languages • Two points of view – bilingualism is an asset, even a necessity, – child should become proficient in own 1st language • How easy is it to be bilingual? – many 6-year-olds have difficulty pronouncing certain sounds – but auditory sensitivity helps young children master pronunciation over time, a much harder task if language learned after puberty • Best solution: children become “balanced bilinguals,” fluent in 2 languages – research confirms children can become equally fluent in 2 languages – easiest way for child to become bilingual is if parents speak 2 languages • ideally, each parent represents 1 language and helps child with mastery • sending child to preschool where 2nd language taught also effective Early-Childhood Education Many Types of Programs • Distinct educational curricula have been developed – Maria Montessori (100 years ago) developed structured, individualized projects for poor children Child-Centered and Readiness Programs • Many newer programs are “childcentered” or “developmental” – use a Piaget-inspired model that allows children to discover at their own pace • Alternative programs stress academic readiness – some readiness programs explicitly teach basic school skills Reggio-Emilia • Reggio-Emilia—a new form of earlychildhood education pioneered in the Italian city of that name – children encouraged to master skills not normally seen until age 7 – artistic expression, exploration of the environment, and collaboration between parents and teachers encouraged • Early childhood is the prime learning period for every child and some learn even more • The above has led to conclusion: nations should provide quality early education • Head Start – has provided half-day education for millions of 3 to 5 year olds, boosting abilities and skills, at least temporarily and probably for longer Quality Learning • Three research projects have shown excellent longitudinal data – High/Scope (Michigan) – Abecedarian (North Carolina) – Child-Parent Centers (Chicago) • Children in these programs have scored higher on math and reading achievement tests than other children from same backgrounds, schools, and neighborhoods • High-quality early education is associated with positive outcomes for all children – what is high-quality education? • safety, adequate space, and equipment • low adult-to-child ratio • trained staff • curriculum geared to cognitive development • learning includes creative/constructive play
