3 of 113
What can imaginary companions be used for?
To deflect blame, vent anger, convey reluctant info and for companionship
4 of 113
Nativists say we are born with a biology module to organise observations into knowledge of living things since we pick up this kind of information v. rapidly. What do empiricists say?
That knowledge of living things comes from observations since a lot of questions are asked between 3-5 years and children's understanding reflects cultural views
5 of 113
What did Oakes and Cohen (1995) find out about causal reasoning?
6-10 months olds have an understanding that inanimate objects can't move independently
6 of 113
Sobel and Kirkhaim (2006) found that 2 year olds are able to...
Work out which blicket detector music will come out of because they can make inferences
7 of 113
What are 2 year olds better at than 1 year olds according to Chen and Siegler (2000)?
At using tools to get an object because they are more able to generalise beyond observations
8 of 113
What do magic tricks tell s about causal reasoning?
By 5 years find them entertaining because understand when there are violations of expectations
9 of 113
How do nativists say ToM develops?
We are born with a module that develops in the first 5 years which gives us an understanding of other's mental states
10 of 113
What do empiricists say about ToM?
Comes from social interactions and information processing skills: that people with siblings outperform others here supports this idea
11 of 113
When do children pass second order false belief tasks?
Posner and Wimner found only 10 year olds when prompted could do this
12 of 113

They understand that another person who likes trucks will prefer to play with this even if they prefer dolls
15 of 113
Can 3 year olds do the smarties task? What does this show?
No. Can't do false belief tasks yet because still egocentric.
16 of 113
What evidence is there that infants fail false belief tasks because they are socially inept?
Perner and Leekam (2008) found they could pass false belief tasks when they were tested in an appropriate format. Goldstein and Winner (2011) found people who act have better ToM so likely to do with social experience.
17 of 113
What evidence is there that false belief tasks aren't just about social adeptness?
False Sign Task (come back to)

25 of 113
When can children make precise discriminations of temporal order?
By 5-9 years
26 of 113
What happens during Piaget's preoperational stage in terms of time?

30 of 113
Piaget thought infants only have a basic understanding of magnitude. What do we know now?
They inderstand time, numbers, space and there are overlapping representations of these concepts in the intraparietal sulcus.
31 of 113
Ruff an Capozolli (2003) tested infants at 10,26 and 42 months on the types of attention they used and the types of distractors that affected them. What did they find?

52 of 113
Give 2 examples of organic retardation?
Downsyndrome and fragile x syndrome

Something that arises in infancy and characterised by IQ below 70. Assessment is based on how well the can function. 95% can hold down jobs in the future but 1-2% can only just manage self care
54 of 113
Why might children learn better in groups?
Because of socio-cognitive conflict: learn from range of perspectives. This stimulates deeper thinking which has long term benefits.

It can't explain the language findings
89 of 113
What is the dorsal stream deficit explanation of william's syndrome?
That due to smaller and higher cell density in dorsal stream and reduced structural connectivity there is less dorsal stream activity (during square completion tasks and object vs location tasks)

47 copies of chromosome 21 rather than 46
100 of 113
What increases the risk of developing downsyndrome? and how can you test for this?

tarkets specific learning deficits using task analysis and positive reinforcement. Uses communicative training. Supportive employment.
102 of 113
What is the National Head Start Programme?

103 of 113
What is the early medical intervention used for fragile x syndrome?
block glutamate receptors in the amygdala to normalise neurons. To do this se prenatal gene therapy. But this has a risk of causing mutations.
104 of 113
What is the memory format change theory of childhood amnesia?
Language development introduces new ways to format knowledge and structure recall. So unable to access preverbal info with new strategies.
105 of 113
What is the neural change hypothesis of childhood amnesia?
Mamories unable to trransfer to LTM because hippocampus is immature so can't store memories. Also unable to use source monitoring to ignore irrelevant info because of immature PFC
106 of 113
What is the cueing hypothesis of childhood amnesia?
Only unable to recall info because not given appropriate cues. These tend to be nonverbal.
107 of 113
What happens between 3 and 5 years to aid storage/retrieval of episodic memories?
Explicit rehearsal of past events. Develop narrative skills to create more elaborate representations to make use of more cues. Use memories to create conversation. These new long term episodic memories give rise to a sense of self
108 of 113
What did Simcock and Hayne (2003) do?
To test whether infants aged 2/4 rely on verbal information to different degrees during memory retrieval they tested memory of the magic shrinking machine after 24 hours.
109 of 113
What 4 measures were used to test children in Simcock and Hayne's study?
Verbal recall using questions. Photo identification. Behavioural re-enactment. MacArthur Communicative Development Inventory to test verbal abilities
110 of 113
What did Simcock and Hayne (2003) find?
4 year olds better recall of shriking machine than 2 year olds in all domain. But 2 year olds did have some memory of the event.
111 of 113
Specifically what did Simcock and Hayne (2003) find out about those with higher vocabs?
Performed better on all aspects of recall suggesting represenational nature of memory changes with age. Earlier memories emcoded non-verbally and only rely on verbal encoding later on
112 of 113
What did Simcock and Hayne conclude from their study?
Evidence in favour of Mmory Format Change hypothesis for childhood amnesia. Harder for younger children to verbally recall events because don't rely on verbal encoding strategies.
