[Lateral effects of emotional stimulation on verbal memory processes in men and women].
Effects of short-term changes in emotional state of men and women on hemispheric organization of verbal memory processes were studied in the model of emotional electrodermal stimulation. Retrieval of dichotically presented lists of words was analyzed. The lists of words included pairs of emotionally neutral word and pairs combined of a neutral and emotional or both emotional words. There were no gender differences in the immediate retrieval of the words. Electrodermal stimulation prior to presentation of list of word resulted in a lateralized reduction of the immediate report of neutral words presented to the right ear and of emotional words presented to the left ear. Gender-related differences were shown in the delayed retrieval. In women, the stimulation applied before word presentation induced a decrease in delayed retrieval of left-ear emotional words. In men, the stimulation applied after the word presentation improved the retrieval of word lists independently of the side of presentation. Mechanisms of gender-related differences in interhemispheric interaction in verbal memory processes are discussed.
