Brain lateralization of various cognitive functions is a widely studied phenomenon due to its possible relationship with cognitive abilities, efficiency, and dynamics. Neuroscientists have used neuroimaging techniques to localize specific cognitive functions. But these methods are costly, time consuming and not available for all researchers. Visual half – field paradigm is one of the alternative methods which is simple, inexpensive and could be used in large samples to determine the dominant hemisphere of specific function. The aim of this study was to investigate lateralization of foreign language and visual working memory and the connections between the lateralization of these cognitive functions using the visual half – field paradigm. In the study 92 participants who performed the translingual lexical decision task were analyzed for lateralization of foreign (English) language, 99 participants – for lateralization of visual working memory. We analyzed how accuracy and response time depends on visual field, how gender is related to hemispheric lateralization and what is the relationship between visual working memory and translingual lexical decision task. The result of study revealed: the accuracy of the TLDT was higher when words were presented in the right visual field and processed by the left hemisphere, this result is independent of the gender; the response time of the TLDT did not differ in the overall sample, but was significantly faster in the male group when the given word was processed by the left hemisphere; the performance in the visual working memory task was faster and more accurate when the stimulus was presented in the right visual field and processed by the left hemisphere, regardless of gender; A direct relationship between visual working memory and translingual lexical decision task lateralization indexes has not been established. |
