The School Years: Cognitive Development

Piaget’s Third Stage

nConcrete operational thought is the ability to reason logically about direct experiences and perceptions.

Logical Principles

nClassification: organization into groups according to common property

Essence and Change

nIdentity: certain characteristics of an object remain the same even if other characteristics change

Essence and Change (cont.)

nReversibility: reversing the process by which something was changed brings the original conditions

Essence and Change (cont.)

nReciprocity is the principle that things may change in opposite ways, and thus balance each other out.

Practical Applications

nThe logical principles of concrete operational thought make learning easier and more fun.

Logic and Culture

nLev Vygotsky believed that culture shapes cognition more than Piaget believed.

Logic and Culture: An Example

nBrazilian street children calculate complex computations not learned in school (see text p. 361)

Moral Development

nDevelops along with cognitive advances

nIs shaped by culture and social influences

nMiddle childhood is a key time for learning moral lessons

Kohlberg’s Stages of Moral Development

nKohlberg presented moral dilemmas and scored responses as:

¨Preconventional: rewards and punishment

¨Conventional: emphasis on social rules

¨Postconventional: moral principlesbeyondsocietal standards

Evaluating Kohlberg’s Theory 

nMoral reasoning does seem to advance with advances in cognitive development.

nMost children are preconventional before age 8, and conventional by age 9 years.

Information Processing

nAnalyzes how the mind analyzes,

nstores, and

nretrieves information.

The Three “Parts” of Memory

nSensory register: registers incoming stimuli for a split second

nWorking memory (short term): where current, conscious mental activity occurs

nLong-term memory = stores information for minutes, hours, days, months, years

Speed of Processing

nSpeed of processing increases during middle childhood.

Automatization

nCertain skills become automatic during middle childhood (e.g., reading, writing).

Language: New Vocabulary

nSchool-age kids learn up to 20 new words a day.

nThey understand metaphors and various uses of words.

Two “Codes” of Language

nFormal Code: used in school and other “formal” situations

¨Extensive vocabulary

¨Complex syntax

¨Lengthy sentences

Code Switching: A Life Saver

nKids in middle childhood learn that certain words and phrases are okay with friends (informal code), but NOT with teachers, pastors, or other adults.

Socioeconomics and Language

nLower-income children tend to have smaller vocabularies, simpler grammar, and more difficulty in reading

Tones and Tricks

nBy 10 years of age, children learn to understand the nuances of language (tone, sarcasm, puns).
