| Abstract: | Two experiments using identical stimuli were run to determine whether the vocal expression of emotion affects the speed with which listeners can identify emotion words. Sentences were spoken in an emotional tone of voice (Happy, Disgusted, or Petrified), or in a Neutral tone of voice. Participants made speeded lexical decisions about the word or pseudoword in sentence-final position. Critical stimuli were emotion words that were either semantically congruent or incongruent with the tone of voice of the sentence. Experiment 1, with randomised presentation of tone of voice, showed no effect of congruence or incongruence. Experiment 2, with blocked presentation of tone of voice, did show such effects: Reaction times for congruent trials were faster than those for baseline trials and incongruent trials. Results are discussed in terms of expectation (e.g., Kitayama, 1990, 1991, 1996) and emotional connotation, and implications for models of word recognition are considered. |
