ABSTRACT

Background: Understanding the style of cognition according to the brain dominance of students is necessary to keep them active and attentive. The study aims to check the cognitive performance and attention of young healthy individuals with right and left brain hemisphericity. Methods: This cross-sectional observational study was conducted at a physiotherapy institute from September 2022 to January 2023. 240 healthy young adults were recruited and informed consent was taken. Brain dominance of individuals was classified by Cognitive Style Brain Dominance questionnaire, Montreal Cognitive Assessment scale and sustained attention by Trail Making Test A, and selective attention by Trail Making Test B. Result: Out of the total recruited number of participants; 50.4% were male (n=121) and 49.6% were female (n=119). The varied brain dominance was seen as Right, Left, and Middle brain dominant to be 29.1%, 33.3%, and 37% respectively. The Spearman correlation was done for outcome measures which showed that medium positive relationship (ρ=0.46) between left-brain dominant and sustained attention whereas a very strong negative correlation (ρ=-0.90) between selective attention and left-brain dominant. Chi-square examines the study parameters and Mean comparison done by Friedman test which was statistically significant. Conclusion: There was significant relationship between left-brain dominance and sustained attention whereas a negative strong relationship between selective attention and left-brain dominance. Hence cognition does not depend upon varied brain dominance.
