The effects of alerting signals in masked priming.

ABSTRACT
Alerting signals often serve to reduce temporal uncertainty by predicting the time of stimulus onset. The resulting response time benefits have often been explained by facilitated translation of stimulus codes into response codes on the basis of established stimulus-response (S-R) links. In paradigms of masked S-R priming alerting signals also modulate response activation processes triggered by subliminally presented prime stimuli. In the present study we tested whether facilitation of visuo-motor translation processes due to alerting signals critically depends on established S-R links. Alerting signals resulted in significantly enhanced masked priming effects for masked prime stimuli that included and that did not include established S-R links (i.e., target vs. novel primes). Yet, the alerting-priming interaction was more pronounced for target than for novel primes. These results suggest that effects of alerting signals on masked priming are especially evident when S-R links between prime and target exist. At the same time, an alerting-priming interaction also for novel primes suggests that alerting signals also facilitate stimulus-response translation processes when masked prime stimuli provide action-trigger conditions in terms of programmed S-R links.

Mentions: For the RT analyses, all error trials and trials following an error were discarded (8.7%). Furthermore, all trials that did not fit the outlier criterion (RTs <150 and > 1200 ms) were also excluded from analyses (0.1%). Prior to the error analysis, only trials following an error were eliminated. Repeated measures ANOVAs were conducted on mean RTs and percent error containing the factors Alerting signal (present, absent), Congruence (C vs. IC) and Prime-type (target vs. novel primes). Results are presented in Figure 1.
