Responder vs nonresponder differences for verbal dichotic listening in women and nonverbal dichotic listening in men are discussed in terms of differences in cognitive function, hemispheric organization, and neurotransmitter function. Pretreatment PA was also predictive of change in depression severity following treatment. This is in large part because practical limitations have made elusive a paradigm for studying brainstem processing of continuous natural speech in human listeners. Heightened left-hemisphere advantage for dichotic words in responders was present among women but not men, whereas reduced right-hemisphere advantage for dichotic tones in responders was present among men but not women. Significance Statement The brainstem is crucial to speech processing, yet a majority of speech studies have focused on the cortex. Patients who responded to fluoxetine differed from nonresponders and healthy adults in favoring left- over right-hemisphere processing of dichotic stimuli, and this difference was dependent on gender and test. Normative data were also obtained for 101 healthy adults (61 women). Perceptual asymmetry (PA) scores were compared for 75 patients (38 women) who responded to treatment and 39 patients (14 women) who were nonresponders. Dichotic listening is an effective means of examining functional asymmetries in speech perception. Right-handed outpatients who met DSM-IV criteria for major depression, dysthymia, or depression not otherwise specified were tested on dichotic fused-words and complex tones tests before completing 12 weeks of fluoxetine treatment. Two new studies replicate differences in dichotic listening asymmetry between fluoxetine responders and nonresponders, and demonstrate the importance of gender in this context. There was no sex difference in less lateralised participants. Studies using dichotic listening, electrophysiologic and neuroimaging measures suggest that pretreatment differences among depressed patients in functional brain asymmetry are related to responsiveness to antidepressants.

However, only women with a significant right ear advantage in the dichotic listening test had more difficulties in LRC tasks than men. observed such that women had higher hit rates than men on. Patients having a depressive disorder vary widely in their therapeutic responsiveness to a selective serotonin reuptake inhibitor (SSRI), but there are no clinical predictors of treatment outcome. In dichotic listening, a right ear advantage for linguistic tasks reflects left hemisphere. Although women were not less lateralised than men. Neuropsychopharmacology 29(9):1752-61, 2004 Sep. To measure the degree of hemispheric asymmetry participants also completed a dichotic listening test.
