Temporal judgements of internal and external events in persons with and without autism

@article{citeulike:2571098, abstract = {When participants make judgments about the onset of self-initiated movements they typically report the movement occurred earlier than it had [Obhi, S.

Because individuals with autism experience reduced preparatory activity prior to a voluntary movement, the present study sought to determine whether these anticipatory biases are exhibited by persons with autism. Participants watched a dot move in a circle and pressed the spacebar any time after one revolution. A tone either followed the participants' voluntary movement or was computer generated. Participants in both groups made anticipatory judgements regarding movement initiation (~100 ms). When the movement and tone occurred together this anticipatory bias was also present, regardless of which event participants focused on.
