using a dichotic listening test, that heterosexual men and women were more lateralized than gay men and. These results contribute to the literature on sex differences in functional cerebral laterality. This is why more men than women are left-handed. Speech sounds processing (dichotic listening task) significantly decreased men's, but not women's, systolic blood pressure. This study investigated the functional brain organization of 68 male-to-female (MtF) transwomen and 26 female-to-male (FtM) transmen by comparing their performance with 36 typical male and 28 typical female controls on two indicators of cerebral lateralization: dichotic listening and handedness. Women were also able to identify significantly more speech sounds presented to the left ear than men, and they were able to dynamically increase accuracy at the targeted ear identified within each focus group (left or right). Researchers have reported contrasting results for the effects of the ovarian hormone changes across the menstrual cycle on results from dichotic listening studies. Men and women both evidenced increased cardiovascular reactivity, with men experiencing significantly more cardiovascular reactivity (SBP) than women in response to cold pressor pain. Also, a compartmentalized, dynamic response in dichotic listening test performance was evidenced in both men and women (as both experienced increased accuracy at the right, but not left, ear), brought about as a function of the cold pressor. Group differences in dynamic functional cerebral laterality were predicted.įindings indicated a sex by focus interaction effect where men's, but not women's, systolic blood pressure increased significantly when focusing on sounds presented at the left ear during the dichotic listening task. Functional cerebral laterality was assessed through the administration of the phonemic dichotic listening task. In Experiment 1, words and pseudowords were presented either to the left or right ear (monaural condition) or simultaneously to both ears (binaural condition). and twenty-four male and female nurses on a dichotic listening task and found. 120 right-handed undergraduate men (N = 60) and women (N = 60) underwent physiological measurements of systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) before and after exposure to the cold pressor and a phonemic dichotic listening task. In two experiments, functional laterality and interhemispheric transfer was investigated in schizophrenic patients (n14) and healthy controls (n17). With the development of more accurately produced dichotic tapes it has. In summary, females dichotic listening performance is less lateralized than that. This experiment investigated sex differences in dynamic functional cerebral laterality effects on cardiovascular reactivity and dichotic listening in response to a stressor (a cold pressor). Scores for men and women in the menstrual cycle study were originally. Among those, 8 6 women, 2 men also participated in the loudspeakers stimulation condition along with a ninth woman who participated only in the loudspeak- ers.
