Effects of increasing and decreasing intratrial stimulus speed on coincidence-anticipation timing.
The effects of intratrial stimulus speeds on coincidence-anticipation timing was investigated. The Bassin Anticipation Timer was used to test 82 participants' response times when the intratrial stimulus speed decreased, was constant, or increased. Analysis showed a significant temporal directional bias with increased and decreased intratrial speed. Decreasing intratrial stimulus speed produced the greatest magnitude of error compared to constant and increasing speeds. Differences in response times associated with intratrial stimulus-speed changes may depend on participants' identifying stimulus speeds and preprogramming a coincident response.
