Emotion and lexical effects in an auditory lexical decision task with vocal affect

  • Author(s) / Creator(s)
  • The present experiment investigated the role of vocal affect in spoken word recognition. Participants performed an auditory lexical decision task with stimuli articulated by a professional male actor with different acoustic realizations of vocal affect (Angry, Neutral, and Joyful). In addition, the effects of Valence, Arousal, Danger, and Usefulness, measures shown to affect lexical processing, were assessed. Results reveal faster responses to stimuli articulated in the Angry vocal affect compared to Joyful and Neutral stimuli. In addition, higher Valence, but not Arousal, Danger, nor Usefulness facilitated word recognition. These results partially replicate the findings of past studies and also contradict the results of some studies. Implications of the results are discussed.
