Figure 1.
Selected frames depicting stimuli from the three conditions (BM, SO, and UO).
Stimuli were point light animations composed of 12 white dots presented against a black background. In the Biological Motion (BM) condition, the stimulus was a point-light walker. In the Structured Object (SO) condition, the stimulus was a rectangle composed of point-lights. In the Unstructured Object (UO) condition, the stimulus was a single frame from the walker animation, inverted.

Figure 2.
There was a main effect of Condition but no main effect of Group and no Group by Condition interaction. Noise threshold (NT) was higher in the Structured Object (SO) condition compared with the Biological Motion (BM) and Unstructured Object (UO) conditions, and higher in the BM condition compared with the UO condition. There was no difference between individuals with Autism Spectrum Conditions (ASC) and Normal Controls (NC).
