Sex differences in the Human Brain Activity During the Associative Memory Testing
Keywords:Associative memory, EEG, activity of the brain, verbal associations by similarity, verbal associations by contiguity
In this paper the activity of the brain during memorization of the different types of associations in men and women. The subjects (20 women and 20 men aged 21+/-3 Year, right-handers) held the following computer subtests «Association by similarity», «Association by contiguity in timе» and «Association by contiguity in space». All subjects recorded EEG before the test and during the tests. It was found that the memorization of the similarity associations in women took place with the involvement of the auditory memory, semantic analysis, intermodal interaction and visual images associative word pairs, while the men memorized pairs of words with the help of pronunciation. Memorization of the associations by contiguity in timе in women has been the most difficult and required the use of the back of the association cortex of both hemispheres. Memorization of the associations by contiguity in space (spatial) in men happened, factuality, through mechanisms of representation and of pronunciation, as opposed to women, who in turn memorized this information by both its figurative representation, verbal and semantic analysis.
