Moving Single Dots as Primes for Static Arrow Targets

Abstract

Abstract. In response priming, responses are typically faster and more accurate if the prime calls for the same response as the target (i.e., compatible trials) than when primes and targets trigger different responses (i.e., incompatible trials). With moving rows-of-dots as primes for static arrow targets, participants instead responded faster to incompatible targets with longer SOAs (stimulus onset asynchrony, > 200 ms). Until now, it is unclear whether this effect is specific to the material. In the present research, a single moving dot was used as a prime. Further, we analyzed compatibility effects depending on reaction times (RTs). Positive compatibility effects in reaction times were found with an SOA of 147 ms and even with a relatively long SOA of 360 ms; for very long SOAs (800–1,200 ms), negative effects were found. We interpreted this as evidence that the specific type of motion is irrelevant for the occurrence of a negative compatibility effect.
