ABSTRACT

Background: The human brain is the seat of cognitive function, which plays an important role in the existence of humans on earth. The cranial volume capacities will facilitate an increase in brain size, which played an important role in the process of evolution. The cephalic index (CI)ratio of the skull bone will indicate the relatively proportional size of the brain. Postnatal brain growth and development is an important factor that play role in achieving academic learning excellence. Based on this professional students' cephalic index ratios and their academic performance scores were studied. Methodology: a total of 150 (male 67+females 83) students of either sex who are studying at JSS academy of higher education and research, Mysuru, Karnataka were included in the study. Their CI ratios were measured by using a spreading. Data were analyzed to verify the level of significance in a different category of CI ratio with marks of male and female separately by using one-way ANOVA and Chi-squared test were used to determine if there's a significant association between gender and cephalic index ratios at 5 % level of significance.Results: Among 150 participants of either sex, there is a dispersed distribution pattern of CI ratios was seen. There is no statistical significance obtained between the type of CI pattern with higher scores neither in theory nor practical scores in the same groups or on comparison between male and female groups. Hence there is no consensus obtained regarding high score significance in dominating a particular cephalic index pattern among these professional students. Conclusion: The present study results suggested that the higher cephalic index ratios are not on par with student academic performance with high scores. Hence the outcome of this study is suggestive of mere CI ratio (skull size) may not be the entity that drives cognitive abilities, especially in the professional student community.
