Human behavior and cognition are characterized by the ability to adapt to a dynamic environment, whether in attention, action or both. From a cognitive psychological perspective, human beings are basically conceptualized as dynamic information processing system whose mental operations can be described in computational terms (Neisser, 1967). Executive functions/mechanisms are of essential importance for goal directed and efficient behavior. They guarantee cognitive flexibility in our daily activities by planning, initiating, configuring and monitoring many perceptual-motor processes. An interesting approach for examining the functional characteristics of executive mental processes is the task/set switching by verifying intercorrelations among processes. WCST is used to determine an individual's competence in abstract reasoning and his/her ability to change problem-solving strategies when needed (Buhren et.al, 2012). A sample of 80 students of age ranges between 15 to 18 years was selected and Wisconsin Card Sorting Test (WCST) was administered for measuring cognitive set-switching. Correlation analysis was applied for analyzing results. Strategies for reducing switch costs may have implications and applications in various areas/aspects of human life.
