Exploring Consistency in Right Hemispheric Hypothesis and Valence Hypothesis for Perception of Emotions in Brain

Abstract

The present study explores the consistency of two hemispheric hypotheses of the brain in perception of emotions: right hemisphere hypothesis, and valence hypothesis in the context of emotional intelligence, sex, and age using the sample of 323 participants. Unlike traditional procedures adopted for Chimeric face test, we developed a software for Chimeric face test with the help of APACHE 2.4 platform in PHP 5.2 application in i-7, 5th generation Intel core-based computer system with male and female faces reflecting four states of emotions—happy, fear, anger, and sad—to measure brain laterality. The level of emotional intelligence among participants is measured using Genos Emotional Intelligence test. By employing multivariate logistic regression analysis, the study reveals that the right hemisphere hypothesis is more dominant than the valence hypothesis in the sampled participants, and observes its dominance lucidly in males. Males with higher emotional intelligence have higher right hemisphere hypothesis responses whereas age has no significant impact on its validation. Valence hypothesis has no impact due to emotional intelligence, sex, or age. For female participants, the presence of the valence hypothesis is not observed, and higher emotional intelligence suggests fewer right hemisphere hypothesis responses.
