Table results

3. Tourette's Syndrome = 20.4 (mean score on eyes task)

2. Control ('normal') = 20.3 (mean score on eyes task)

1. Autism/Asperger's = 16.3 (mean score on eyes task)

No difference between Group 2 and Group 3 on eyes task

Group 1 scored much lower on eyes task than the other 2 groups

Strange stories task used to test concurrent validity of the eyes task

Asked "Which word best describes what this person is feeling or thinking"

Forced to choose between 2 emotions

Shown for 3 seconds

Eyes task

25 standardised photos of eyes

Black and White

Quasi experiment

3 groups

10 Participants

Assumed to have normal IQ

Drawn from general population of Cambridge

50 Participants

25 female

25 male

Mean IQ of 105.3

12 with Asperger's syndrome

4 with high fuctioning autism

3 female

13 male

16 participants

Provide more support for the cognitive explanation of autism

eye task meant describing the emotion displayed by eyes

The theory of mind test used was the eye test

That autistic adults lack theory of mind skills.

Keywords

Loftus and Palmer
Study 2

Conclusions

Loftus and Palmer suggests there are two types of information for memory

2. Information we get after the event

1. Information from perceiving the event

Post event information distorts actual memory

Supports Study 1

Wording of question affected the participants memory of the event.

Smashed = more than twice as likley to see glass

Stats

Control

6/50

7/50

16/50

One Week later all subjects asked again

Did you see any broken glass?

Groups

Group 3

Not asked (Control)

Group 2

How fast were the cars going when they hit eachother

Group 1

How fast were the cars going when they smashed into each other

Procedure similar to study 1

Three groups of 50

150 students

Study 1

Conclusion

2. Responce Bias - demand characteristics

1. Verb distorts actual memorey

Results

The worse sounding the verb = the faster speed estimate

Method

DV

Estimate of speed

IV

Verb used in question

Five differrent verbs (one per condition)

Contacted

Hit

Bumped

Collided

Smashed

critical question was ''about how fast were the cars going when they ***** each other

asked to complete a questionnaire

Asked to write a short account of what they had seen

Seven clips of traffic accidents

Laboratory Experiment

Participants

Five groups of nine

45 students

Aim

Will the use of more severe sounding verbs to describe an accident leade participants?

Be more likley to (incorrectly) recall the presence of broken glass?

Produce a higher estimate of speed??

To investigate the effect of leading questions on the accuracy of eyewitness testimony
