In recent years there has been an explosion of interest in questions concerning the relations among emotional and attentional experiences. Priming studies (Fazio, Sanbonmatsu Powell, & Kardes, 1986) have demonstrated that response latencies to target stimuli are mediated by the affective relation between prime and target. The time to evaluate or pronounce targets is facilitated if preceded by similarly valenced primes (e.g., cancer-pain), but is inhibited for trials on which prime and target have an opposite affective valence (e.g., cancer-joy). This finding was replicated and extended in a number of studies showed that the effect is independent of word length and can therefore be generalized to a large type of stimuli. This article revises emotional priming paradigm and suggests his usefulness procedure could be used widely in cognitive-experimental research, social and clinical psychology.
