A Study on Left-Brain Dominance of the Higher Secondary Students

Abstract

This present study intends to find the left-brain dominance of the higher secondary students in Tirunelveli, Thuthukudi, Kanyakumari, and Virudhunagar districts in Tamilnadu, India. In this survey study, the population consists of 2000 higher secondary students of the above-mentioned districts of Tamilnadu, among this population, based on the result, the population was separated by left, middle or moderate and right brain dominant by the instruction of the scoring key. Here, 743 higher secondary students were coming under the left-brain dominance, 135 were in the right brain and 1122 higher secondary students were in middle or moderate brain dominance. In this study, the investigator examined only the left-brain dominance of the higher secondary students. The alert scale of cognitive style by Loren D. Crane (1989) was used to collect the data for this present study, which consists of 21 optional statements. Necessary instructions were given to every student before they asked to do the questionnaire. The scoring was done according to the scoring scheme and the formulated hypotheses were tested using appropriate statistical technical like percentage analysis, and chi-square. The findings indicate that the left-brain dominance of the higher secondary pupils’ level is moderate and there is a substantial association between family income and districts community of the higher secondary students and their left-brain dominance.
