| Moving stimuli represent salient stimuli which are able, for example, to guide attention and eye movements fast and unintentionally. Until now, there are only few response priming experiments using moving stimuli. Response priming refers to the finding that the response to a target stimulus that follows a prime stimulus is influenced by the prime stimulus. Typically, there are faster Responses when prime and target require the same response (i.e., congruent trials) compared to different responses (i.e., incongruent trials). We showed in own studies that this pattern is reversed with stimulus onset asynchronies (SOAs) above 200 ms when we used moving stimuli as primes. In the current experiments, we conducted several response priming studies with biological moving primes (point-light walker and stylized eye movements) and static arrow targets and varied the stimulus onset asynchrony (SOA) between prime and target. Most interesting, with biological movements (especially point-light walkers) we found huge positive priming effects for SOAs of 180 and 360 ms, and smaller but still positive priming effects with rather long SOAs of 800 and 1200 ms. Results were discussed according to different theories on negative compatibility effects and theories on perception and processing of biological motions. |
