Flashcards in Week 7- Piaget more stage 1 Deck (14):
1

Critiques of sensorimotor stage, talk about underestimation:

-Piaget may be underestimating the children’s abilities
-His methodology is difficult, he wants infants to behave intentionally to show that they know stuff, he wants them to show motor control to show that they know stuff
-If he asked a simpler question, they might have had skills that he didn’t notice

2

Critiques of sensorimotor stage, talk about imitation:

-Weren’t able to represent the act b/c they don’t have mental representation (can’t imitate)
-People arguing that Piaget's task was too hard (could make it simpler)

3

Critiques on stage 1 - Imitation. Meltzoff & Moore exposed babies that were 12-20 days old to a male model making faces. What happened here in terms of imitation?

-face: tongue protrusion, mouth opening, lip purse
-see if baby imitates the guy … sometimes
-40% of babies made a tongue protrusion when model does tongue protrusion
-10% of babies did mouth opening when model does tongue protrusion
-2% of babies do tongue protrusion when adult is doing mouth opening
-8% of babies do mouth opening when adult does mouth opening

4

We can't find any reliable imitation in babies until they're about __ months of age. (substage ___)

9, 4

5

When does deferred imitation come into play? What substage?

18 months +
(substage 6)

6

Critiques on stage 1 - Deferred imitation. Collie & Hayne put babies in a room and a model did cool things like turn on lights and some models did not do this, What were the results in terms of deferred imitation?

-Babies who had seen the model touch the button the previous day were more likely to push the button than babies who did not see the model push the button

7

Critiques on stage 1 - Memory. What do people argue about habituation/dishabituation research?

-Some people will argue that newborns who do this task use some sort of rudimentary form of memory
-Some evidence of the ability to form memories

8

Critiques on stage 1 - Memory. Rovee-Collier put a mobile over a 3 month-old baby's crib for them to look at. What was the control group and experimental group? What were the results? What did the results suggest about 3 month olds in terms of memory?

-Control group: they lied there
-Experimental group: string on ankle, if they kicked -> mobile moved
-They learned quickly that kicking makes mobile move -> within a few minutes they doubled or tripled kicking rate
-sends babies away, brings them back a day or two later after training
-Places them in crib, (no string) watches to see how often they kick
-Control babies kick the same in both situations
-Experimental babies kicked significantly more in test situation where there was no string attached
-Its suggested that 3 month olds can form simple rudimentary memories

9

Critiques on stage 1 - Object Permanence. Explain the A not B task.

-Response inhibition (A not B)
-put object behind door A, cover it, ask where it is, they point at A, repeat a few times
-put object behind door B, ask where it is, they see you changed it but still say A
-They’re looking where the object really is but reaching somewhere else

10

Critiques on stage 1 - Object Permanence. Explain the point about Motor search-> intentionality.

-In substage 4, babies demonstrate object permanence by picking up a blanket that’s covering a toy (rudimentary evidence)
-We have a confound between the result (object permanence) and the criteria (ability to engage in motor search) -> some people think Piaget screwed up there

11

Critiques on stage 1 - Object Permanence. Talk about Baillargeon's impossible events.

-habituation/dishabituation paradigm
-Then hit them with an impossible event
-Car goes down track behind block, they show that a box is on track but then person moves it when it is hidden and baby thinks its impossible so they stare longer at the box on track
-When there is an impossible event -> baby is surprised and stares longer

12

Critiques on stage 1 - Object Permanence. Baillargeon's impossible events- Evidence of Object Permanence at 4.5 months, explain fan experiment.

-control group: habituation to fan without box
-experimental group: habituation to fan with box
-test impossible event (fan going through box), if they look longer at box, is it OP? only if they don't generally look longer at longer events

13

Critiques on stage 1 - Object Permanence. Baillargeon's impossible events- Evidence of Object Permanence at 3.5 months, explain short carrot and tall carrot passing behind screen experiment.

-Short carrot or tall carrot passing behind screen
-Babies habituate to carrots going through
-Possible and impossible event
-Screen changes so that there’s a hole cut into it (window), short carrot is shorter than window so you see that come out the other side
-With the tall carrot, you should see it in the window but you don’t -> impossible event
-Babies look longer at impossible event but become less interested pretty quickly b/c they figure there must be two carrots

14

Overall evaluation of stage 1?

-more or less accurate picture of infants’ abilities
-only real critique is underestimation: methodological limitations
