Abstract: Individuals with more anxiety reveal more right frontal activity and they respond towards negative emotions and the individuals with left frontal activity exhibit more positive emotions. The present study aims to investigate the impact of CBT on frontal asymmetry on the students having more levels of test anxiety and EEG activity was measured in 16 higher secondary students with higher levels of test anxiety before and after cognitive behavioral therapy (CBT).After CBT students shifted towards greater relative left frontal brain activity. Students with greater left frontal activity were having lower levels of test anxiety and the results indicated that CBT reduced test anxiety and brought out the changes in frontal asymmetry. It is concluded that CBT has an impact on frontal asymmetry and test anxiety levels of students.
