Cerebral dominance in spatial hearing and working memory abilities in adults with normal hearing sensitivity

Abstract Background Cerebral dominance refers to the biological description of brain, where one cerebral hemisphere is dominant over other in certain functions. There scanty literature on and its impact auditory spatial processing working memory, which explored study. Methods A total 45 participants with normal hearing were divided into three groups 15 participants. The categorized based scores obtained alert scale cognitive style checklist as bilateral dominant, left right group. was assessed using interaural time difference (ITD), level (ILD), virtual acoustic space identification (VASI) tests, whereas memory abilities tested forward span, backward ascending digit descending 2n back tests. Results MONOVA results indicated that there no significant main effect all In hearing, although ILD thresholds not influenced by dominance, seen VASI accuracy scores. Post-hoc analyses showed group demonstrated significantly better perception compared groups, latter showing similar performance. Conclusions While ITD tests fall short revealing asymmetry, VASI’s power capturing effects makes it a valuable tool assessment. study’s findings highlight need for assessing before administering
