5: Preschool Cognitive Measures Flashcards
List five advantages for search tasks.
Game-like.
Ecologically valid.
Easy to control variables.
Used across wide range of ages.
Feedback inherent, but not negative.
Describe Piaget’s A-not-B task. What tends to happen and what does this argue?
Hide attractive toy under box “A”, baby searches for toy and finds it, activity repeated several times. Experimenter moves toy under box “B”, also within easy reach of baby.
Babies 8 months or younger perseverate, meaning they look under box “A” even though saw experimenter move toy under box “B”. Piaget argued this meant lack of object permanence.
What three design changes affect the A-not-B task?
With age, increasing delay to err required.
Increased distance = fewer mistakes.
Increased distinctiveness of covers = fewer mistakes.
The A-not-B task implies memory failure. Why is this?
Proactive interference: displacement of new information by old information.
What did Diamond argue about the A-not-B task?
Implies memory AND inhibition failure. Know where to search but when memory (or representation) fragile, cannot compete with previous rewarded behaviour.
What occurs in the sandbox A-not-B task with preschoolers?
Biased to A when searching at B.
Describe the two basic findings of DeLoache’s Model Room Search Task. What is an explanation for them?
Symbolic development: age 2.5 have difficulties using model of room to help them search in a room, 3.0 do well.
Both age groups remember well.
Dual representation: symbol and object.
Provide a piece of supportive evidence for DeLoache’s Model Room Search Task.
If emphasize object properties (or deemphasize symbolic properties) leads to poor performance by 3-year-olds (e.g., play with model). Reverse leads to better performance (e.g., behind window).
What happens if you remove the symbolic requirements in DeLoache’s Model Room Search Task.
If children believe model is room itself (not a symbol for the room), do much better (picture, video, credible shrinking room).
What are the conclusions of DeLoache’s research?
Difficulties are with representing symbolic properties of the model because of its salient object properties.
Mazes, where kids search for the correct path, is what kind of measure? What are two advantages to this measure?
Planning measure.
Can vary difficulty, useful across wide age range.
Difficulty in mazes can be varied by what three things?
Number of turns to solution (e.g., 4 vs. 22 turns).
Number of alternate paths.
Length and number of turns in alternate paths before dead end reached.
Executive functions are thought to control ones’ novel what?
Thoughts, actions, emotions, attention.
List four examples of higher cognitive processes associated with executive functions.
Planning.
Working Memory.
Motor Response Inhibition/Inhibitory Control.
Cognitive Flexibility.
List four infant/preschool measures of working memory.
A-not-B.
Spin the pots.
Forward/Backward digit span: listen to series of digits, repeat series in correct forward or backward order.
Forward/Backward word span.
