If valid, then performance of Eyes Task should correlate with Strange Stories Task. (Example of concurrent validity). * 3. Control Tasks - Group 1 given 2 controls to check if difficulties with Eye Task were due to other problems. 1. Gender recognition of Eyes Task - Indentify gender of eyes. Such judgement doesn't involve mindreading, but involves face perception. Therefore, this controls difficulties in that area. 2.

This was to check whether poor performance on Eyes Task could be linked to a problem recognising basic expression rather than lack of ToM. Controls: * Standardised photos - Same size, eye region, and all black and white. * 2 Control tasks - To check if poor performance of Eyes Task in Group 1 was due to other factors. ...read more.

(types of people/ gender in normal group) Dis. - Not "true experiment". - Repeated measures in different order to overcome order effect. * Individual Differences - Autism/ Asperger's Syndrome/ Tourettes/ Normal |___________ Types of people _____________| * Ecological Validity - Low because ppts could only see eyes and irl, most people are used to see the whole face. Just eyes = not very real-like situation. * Sample - All adults - Autistic/ Asperger's -16 ppts (13m/3f) - Mean IQ 105 - Normal - 50 ppts (25/25) - IQ ? 85 - Tourette's - 10 ppts (8m/2f) - Mean IQ 103.5 * Type of Data - Quantitative = Ad. - Easier to analyse. Dis. - Loss of rich data. * Applications - Useful/ helpful for people educating and interacting with Autistic people. Help the Autistic. * One Change - Sample - Same number of ppts in each sample group. - Use variety of people with different cultures and socio background + other countries. ...read more.
