Cognitive abilities refer to brain based skills that are required to carry out any task ranging from the simplest to the most complex. Since these skills play a significant role in our day to day activities, efforts are being made by researchers for their further enhancement. The objective of the present study was to investigate if these abilities can be enhanced through a training module on critical thinking. Critical thinking involves something more than cognitive skills. Critical thinking is not static but a constantly evolving process and even more crucial in a military environment. This study consists of certain activities which are designed in such a manner that the solution of it can be generated through critical thinking. These activities were administered on 36 participants (20 male, 16 female). Each Participant’s baseline cognitive performance was assessed after which training was given to them in the form of different critical thinking activities followed by post assessment of cognitive abilities. Paired sample t - test was used which showed that There was a significant difference in the cognitive performance post critical thinking activities.
