Emotion Word Type and Affective Valence Priming at a Long Stimulus Onset Asynchrony
Published online on June 29, 2015
Abstract
As the division between emotion and emotion-laden words has been viewed as controversial by, for example, Kousta and colleagues, the current study attempted a replication and extension of findings previously described by Kazanas and Altarriba. In their findings, Kazanas and Altarriba reported significant differences in response times (RTs) and priming effects between emotion and emotion-laden words, with faster RTs and larger priming effects with emotion words than with emotion-laden words. These findings were consistent across unmasked (Experiment 1) and masked (Experiment 2) versions of a lexical decision task, where participants either explicitly or implicitly processed the prime words of each prime-target word pair. Findings from Experiment 2 have been previously replicated by Kazanas and Altarriba with a Spanish–English bilingual sample, when tested in English, the participants’ functionally dominant language. The current study was designed to extend these previous findings, using a l000-ms stimulus onset asynchrony (SOA), which was longer than the 250-ms SOA originally used by Kazanas and Altarriba. Findings from the current study supported the division between emotion and emotion-laden words, as they replicated those previously described by Kazanas and Altarriba. In addition, the current study determined that negative words were processed significantly slower in this experiment, with a long SOA (replicating findings by Rossell and Nobre).
