Working and Long Term Memory in Infants
- working memory span is very small
- long term memory: recognition is better than recall
the set of memories about yourself
Why does infantile amnesia occur?
Infantile amnesia says that memories in infants don't occur until age 2/3. This is because:
- hippocampus, which is responsible for LTM, is underdeveloped.
- frontal lobes, used for manipulating and encoding information, are underdeveloped.
- self schema, which gives more context to identity, is not developed
Young children can remember information, but do not remember where it came from. This can yield false memories because they can confuse imagined memories with real ones. This makes children unreliable eyewitnesses.
the last part of the brain to develop and reach maturity in late adolescence. They are related to higher-level cognition, like reasoning, problem solving, judgment and decision making, and inhibition.
Memory in Older People
- working memory tasks that require use of the CENTRAL EXECUTIVE yield slower response times
- same 7+/- 2 working memory span
Long-Term Memory Changes in Older People
• Implicit memory does not decline: procedural conditioning, priming, still works!
• Explicit recognition memory shows little or no decline
• Explicit recall memory shows decline from young adulthood but is less likely for highly intelligent people
