Cerebral Lateralization: Relation to Subject's Sex

Abstract

Patterns of reflective LEM's have been correlated to a number of cognitive and personality variables, bu the relationship to sex, education, and mental illness is unclear. In this study females produced significantly more R-LEM overall indicating a preferential use of left hemisphere mechanisms when they initiate reflective thought. Females also produced more R-LEM for verbal nonemotional material, suggesting stronger lateralization of language abilities to their left hemisphere. Emotional and spatial stimuli were less well lateralized to the right hemisphere in females, and education was an unimportant variable for both sexes. Schizophrenia was independently associated with increases in total R-LEM indicating increased left hemisphere activity in this group.

Facial Feature Movements Caused by Various Emotions: Differences According to Sex

“…On the other hand, many studies regarding right hemisphere processes argue that since nonlinguistic functions are based on the right hemisphere, they may not be related with handedness. From the viewpoint of sex, in the middle of controversies over the roles of sex as a variable that acts of laterality data [23,24], there are grounds for the arguments that the lateralization patterns of males and females are different from each other. In relation to linguistic processing, several studies have argued that females have weaker laterality than males [25,26].…”

Diagnostic Applications of Speech Audiometry

“…That is, on the average the age-related PB versus SSI difference is more pronounced in females than males. Age and sex are factors in performance for dichotic speech tests also (Amerman and Parnell, 1980;Curry, 195 Milstein et al, Schweitzer and Chacko, 1980 In an attempt to answer these questions, speech audiometiy data were analyzed for 573 patients, aged 13 through 89 years. None .reported a history of head injury, emotional disturbance, diabetes, heart disease, stroke, or neurological dysfunction.…”
