Q

Evaluating Piaget’s Concrete Operational Stage

Q

Guided participation

A

Guided participation emphasizes the active role of the child in learning and cognitive growth and the complementary role of parents and other caring adults in supporting,

22
Q

Vgotsky: language and thought

A

As social speech is transformed into private speech and then inner speech, the culture’s preferred tools of problem solving work their way from the language of competent guides into the thinking of the individual.

23
Q

What is memory?

A

the retention of information over time

24
Q

encoding

A

getting info into memory

25
Q

storage

A

retaining info over time

26
Q

retrieval

A

taking info out of storage

27
Q

long term memory

A

relatively permanent and unlimited

28
Q

short term memory

A

can hold a very limited amount of information for a few seconds

29
Q

working memory

A

a short-term “storehouse” for information one is actively working on

30
Q

explicit memory

A

conscious or intentional recollection

31
Q

implicit memory

A

remembering that occurs without effort or conscious awareness

32
Q

Recognition memory:

A

noticing when a stimulus is identical or similar to one previously experienced

33
Q

Recall memory

A

deliberately calling to mind objects and events without any clear reminders

34
Q

Cued recall

A

actively retrieving memories with the help of a hint or cue.

35
Q

infant recall

A

by 2 months (Rovee-Collier, string to baby toe)

36
Q

deferred imitation (infants)

A

By 6 to 9 months, infants can remember and imitate a sequence of behaviours that they learnt through observation alone, and have not practised (pure recall).

37
Q

infantile amnesia

A

-fuzz trace theory:

children more likely to use verbatim memory/adults on gist memory

38
Q

Generic memory

A

produces a script (general outline) of a familiar, repeated event

39
Q

Episodic memory

A

awareness of having experienced a particular incident

40
Q

Autobiographical memory

A

Episodic memories that form a person’s life history – events that have happened to you.

41
Q

Accuracy of eye witness from children increases if…

A
  • children are interviewed only once, soon after the event
  • the interviewers do not ask leading questions, ask open-ended rather than yes/no questions, and do not repeatedly ask the same questions
  • the interviewers are neutral, patient and non-judgemental
42
Q

Phased interview approach

A
  • establish rapport with the child
  • ask to tell you everything about the case
  • ask open-ended questions
  • ask closed, specific, but non leading questions
  • close the interview
43
Q

Why does children’s memory improve?

A
  1. changes in working memory capacity
  2. changes in memory strategies (selective attention)
  3. increased knowledge about memory
  4. increased knowledge about the world
44
Q

Experise

A

extensive, highly organised knowledge and understanding in a particular domain

45
Q

in late adulthood declines generally occur in..

A
  • working memory
  • processing speed
  • explicit memory
  • recall memory
46
Q

Influences on the memory of older adults

A
  • physiological factors and health
  • beliefs and expectations
  • education and memory tasks
  • memory training
47
Q

Representation

A

between the ages of 2.5-3 years, dramatic developments occur in children’s ability to use symbols to guide their problem-solving activites

48
Q

Planning

A
  • thinking further ahead and keep more steps in mind

- become more flexible in their use of planning strategies

49
Q

Strategy choice

A

Siegler: children of all ages use a variety of problem-solving strategies when faced with a problem

50
Q

Transferring skills

A

-even toddlers demonstrate analogical transfer

51
Q

Analogical transference

A

Analogical transfer is transfer of a basic structure acquired through one or more instances to another instance.

52
Q

Practical problem-solving and expertise in adulthood

A

practical problem solving improves during early and middle adulthood as expertise develops
