Summary of Information Processing

Theories

  • Child as Problem solver
  • Thinking as a Process that occurs over time
  • Computer as Metaphor
  • Emphasis on Mechanisms of Change 5

Memory in Childhood

  • Evidence of Infant Memory
  • Metamemory
  • Autobiographical Memory
  • Child Eyewitness Testimony

Evidence of Infant Memory

  • Pacifier Study of Infant Preferences (“Cat-in- the-Hat” study)
  • Rovee-Collier’s Mobile Task with 2- & 3- month-olds
  • Brain Development

Mobile Task

  • Contingency Learning & Memory
    • Carolyn Rovee-Collier Baseline Kicking Rate Learning Phase (Measure Kicking) Memory Assessment (Measure Kicking)

Autobiographical Memory

  • Contributing Factors
    • Basic memory skills
    • Language
    • Parent-Child Conversation
      • Cultural Differences
    • Sense of Self

Infantile Amnesia

  • Why do we have it?
    • Do children < 3 lack the ability to form memories?
    • Did those events happen too long ago (sheer passage of time)?
    • Are early memories simply stored differently than later memories?
  • Possible reasons:
    • Earlier memories stored iconically, later memories stored in language
    • Autobiographical memory not yet in place – no timeline or context in which to place it

Memory Development (Recap)

• Infants:

  • Need visual cues (Rovee-Collier’s mobile tasks)
  • Have non-verbal memories (because they’re nonverbal)
  • Young children
  • Can report memories (because they are verbal)
  • Can remember things that happened a long time ago (6 months ago, 1 yr, 2 yrs, etc.)
  • But their memories are very, very suggestible.

Suggestibility of Child Memory

  • Kelly Michaels “We Care” Case
    • Lots of “memories” were reported
    • Problems with the interview process
    • If you are interested in a summary of this case see http://en.wikipedia.org/wiki/Wee_Care_Nursery_Sc hool

Suggestibility of Child Memory

  • What kinds of experiments do psychologists use

to establish how reliable or suggestible children

really are?

Research on Child Suggestibility

  • “The big yellow giraffe”
    • Effects of repeated questioning
    • Better by age 7/

Research on Child Suggestibility

  • “The big yellow giraffe”
  • “The eye patch”
    • Effects of the memorability of the event
    • Don’t use this as a guide to memory until age 9 or

Research on Child Suggestibility

  • “The big yellow giraffe”
  • “The eye patch”
  • “That clumsy Sam Stone!”
    • Effects of stereotyping

Once upon a time

  • Autobiographical memory
    • Pollyanna principle
    • Recall of material that "fits" current self-view
    • Particular periods of life are remembered more easily than others

Remembrances of Things Past

Information-Processing Deficits

  • Inability to inhibit irrelevant information and thoughts declines
  • Speed of processing declines
  • Attention declines
  • Less efficient retrieval methods

Biological Factors

  • Brain and body deterioration
    • Especially frontal lobes
    • Some studies also show deterioration of hippocampus
