2

Memory in childhood

Working memory increases 2-12 yrs. more reliance Older children are much better at rejecting misleading pre-event (stereotype) and post-event suggestion infomration 5-6 vs. 3-4 yrs. Strategy use parallels development of recall rehearsal (6-7) organization 9 more complex schemas at after age 2

3

Memory in elderly

loss shown mainly in unusual tasks digit span young 20 yr same as elderly 70 yr words in alphabetical order young= 3.2 words, elderly=1.7 words

sentences normal syntax and semantics

4

Long term memory

In implicit memory and recognition young equal to elderly recall of stories young better than elderly reasons for lower recall cognitive slowing working memory capacity there maybe no overall reason

5

Metacognition

Metamemory in childhood less MM in young children

6

Language development

strong evidence against behaviorism children learn children, speech sound learning

7

Speech sound learning

Infants know many speech sounds language production 2-8 months cooing mainly vowels to babbling many vowels and consonant combinations, motherese mothers and primary care fathers seek to know the best speech patterns to use. Perhaps infants leas parents in this first word at 1 yr, fast learning after 1.5yr
