Eligibility

Age

12 Years to 99 Years

Inclusion criteria

Inclusion criteria: - Presence of an autism disorder according to the DSM-IV criteria for autism, diagnosed by a professional clinical team, (possible added with an score of the Autisme Beoordelingslijst (ABL) which is administered by certified raters) - Age between 14 and 23 years - Normal hearing and normal or corrected to normal vision - Written consent by parent or caregiver and/or adolescent

Exclusion criteria

Exclusion criteria: - Evidence of a serious medical, neurological or psychiatric illness (apart from autism), seizure disorders, trauma or a use of medications affecting the nervous system - color blindness;Individuals in the control group are excluded if there are concerns about: - learning disabilities - mental retardation - language delays - head trauma - psychiatric conditions

Design outcomes

Primary

Measure	Time frame
Task 1. the main parameter is task 1 is visual latency; the difference between the reported and the actual time on the target clock. This parameter is calculated for each trials in each condition. To examine the "pure" effect of a sound, difference scores between the vision-only baseline and the sound conditions are calculated. Task 2: the speed of shift attention is the main paramtere in this task. This speed is calculated by comparing Reaction times (RTs) between valid and non-valid trials. The RTs are corrected for accuracy. Task 3: The main parameter in task 3 is the Just Noticeable Difference (JND) for visual temporal order. The JND reflects the smallest time difference (in milliseconds) between two flashes that participants need to perceive correct visual temporal order. Task 4: main parameter is RT of the visual search. The RT refletcs the time to respond to the visual target from the search display onset. RTs are corrected for acuracy.	—
