Auditory Affect Perception in a Dichotic Listening Paradigm as a Function of Verbal Fluency Classification

Abstract

This study evaluated cerebral asymmetry for affect perception as a function of fluency classification. After being assigned to a fluency category using scores on the FAS test (Borkowski, Benton, & Spreen, 1967), forty-five right-handed subjects with normal auditory acuity listened to the Bryden and MacCrae (1989) Dichotic Emotional Words Tape. Subjects higher in fluency exhibited significantly greater right and left ear advantages than subjects lower in fluency. Conversely, REA scores for words were significantly greater than REA scores for affect, while LEA scores for affect were significantly greater than LEA scores for words.

Frontal lobe regulation of blood glucose levels: support for the limited capacity model in hostile violence-prone men

“…From this initial screening, 34 right-handed men met criteria as either low or high hostile men and agreed to participate in the experiment. Women participants were not included at any point of the online screening or the experiment due to sex differences in cerebral laterality [48–50]. Overall, the participants reported no previous history of developmental problems, hypoglycemia, hyperglycemia, hypertension, hypotension, or hyperthyroidism.…”

Neuropsychological effects of hostility and pain on emotion perception

“…Emotional dichotic listening tasks may also employ the use of nonlinguistic affective sounds presented in positive or negative tones (i.e., giggles, groans, sighs; Pollak, Holt, & Wismer Fries, 2004). Previous research using emotional dichotic listening tasks indicate a left ear advantage (right hemisphere) for the perception of affective tone (Bryden, Ley, & Sugarman, 1982;Bryden & MacRae, 1989;Bulman-Fleming & Bryden, 1994;Jancke, Buchanan, Lutz, & Shah, 2001;Snyder et al, 1996;Voyer, Russell, & McKenna, 2002). The left ear advantage for affective tone is thought to reflect the functional role of the right hemisphere in emotion perception (Bryden & MacRae, 1989).…”

“…Thus, varying the tone of voice of the dichotic messages can provide an alternative measure for emotion lateralization (Bryden, 1988). Previous research using dichotic listening to assess emotion lateralization has primarily used neutral words with varying emotional prosody (Bryden & MacCrae, 1989;Snyder, Harrison, & Gorman, 1996). Participants are asked to identify the emotional tone or the word that was spoken.…”
