警报信号通常可以通过预测刺激发生的时间来减少时间不确定性。由此产生的响应时间优势通常可以通过基于已建立的刺激-响应 (S-R) 链接促进刺激代码到响应代码的转换来解释。在掩蔽 S-R 启动警报信号的范例中，还调节由潜意识呈现的启动刺激触发的反应激活过程。在本研究中，我们测试了警报信号对视觉运动翻译过程的促进是否关键取决于已建立的 S-R 链接。警报信号导致掩蔽启动效应显着增强，其中包括和不包括已建立的 S-R 链接（即目标与新颖的启动）。然而，对于目标而言，警报启动相互作用比对于新颖启动物更为明显。这些结果表明，当启动物和目标之间存在 S-R 连接时，警报信号对掩蔽启动物的影响尤其明显。与此同时，新颖启动物的警报启动相互作用表明，当掩蔽启动物刺激在编程的 S-R 链接方面提供动作触发条件时，警报信号也促进刺激-反应翻译过程。
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 fi.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.
