Most Studies of Motion Coherence with ASD Children Have Shown

Most studies of motion coherence with ASD children have shown behavioural impairments compared with controls when:

A) longer periods of time are available to globally integrate visual information
B) basic integration of motion coherence stimuli is required
C) motion coherence stimulus speed is fast (making it easier to perceive motion direction)
D) motion coherence stimuli had a very limited dot lifetime (appear briefly)
