Response procedure and laterality effects in emotion recognition: implications for models of dichotic listening.

The present study manipulated response procedure in a dichotic emotion recognition task as a means to investigate models of dichotic listening. Sixty-seven right-handed students were presented with dichotic pairs of the words bower, dower, power, and tower pronounced in a tone of sadness, anger, happiness, or neutrality. They were asked to identify the two emotional tones presented in each pair and completed the task twice, in two sessions separated by the administration of a handedness questionnaire.

Simultaneous masking in a dichotic emotion detection task.

The present study investigated the possible role of ceiling effects in producing laterality effects of small magnitude in dichotic emotion detection. Twenty two right-handed undergraduate students participated in the present experiment. They were required to detect the presence of a target emotion in the expressions tones of happiness, sadness, anger, and neutrality presented dichotically.
