Cognition is the process or act of knowing and able to make some judgment about it. It is very broad which include a complicated mental process encompassing functions like perception, memory, learning, and problem solving. Cognition includes more than few elements or processes which all work to describe the manner by which knowledge is built up and also how judgments of people are made. The elements related to these processes are: perceiving, recognizing, reasoning, problem solving, conceptualizing, learning, memory, and language (Scienceclarified, 2008).
The individual's ability to comprehend or the cognition ability is necessary for a scientific understanding what human behavior is all about. According to the investigations of various experts, mental processes like association, recall process, and understanding about language are based on the physical relations or interactions of people with their environment, instead of the body which supports the mind; it is basically viewing the body as a support system for a mind. Cognitive structures advance from perception and action like a software (Turing, 1950) which can run on different hardware systems. Human mind can manipulate abstract symbols based on the interactions of people around via his sensory organs as well as greatly coordinated effectors.
Wilson (2002) has six various claims about cognition: 1) cognition is situated; 2) cognition is time pressured; 3) cognition is off-loaded onto the environment; 4) the environment is a component of the cognitive system; 5) cognition is for action; 6) an offline cognition is body based. He further emphasized that, sensorimotor functions which evolved for action as well as perception have been preferred for the application of offline cognition. Therefore, it is logical to say that, cognition is based on the functions of human body and interdependent with the environment. Some current experiments have demonstrated that perceptual as well as motor representations, take part in higher roles of the cognitive processes like the activities which take place in retrieving information from memory and understanding language (Pecher, Zeelenberg, & Barsalou, 2003; Glenberg & Kaschak, 2002; Spivey, Tyler, Richardson, & Young, 2000; Zwaan, Stanfield, & Yaxley, 2002).
Enhancement of Cognitive Abilitites
A recent online survey conducted by Nature magazine from 1,400 scientist reader found out that, one out of five admitted stimulant users engage in taking specific "enhancement" thinking that it can boost brain power. Meanwhile, 80 percent replied that they thought such drug utilization should be permitted. The said revelations obviously suggests a well-known acceptance of "cognitive enhancement" through pharmaceutical means, at least in the midst of scientists interested as much as necessary to respond to a particular online survey (MSN Health and Fitness, 2009).
Dimensions of Emotion
An individual person is not whole in the absence of his emotional being. Emotions according to Lazarus (1991) are multi- component reaction tendencies which unfold over quite short time spans. The emotion process starts with an individual's assessment about the personal meaning of various antecedent events in which is called the "adaptational encounter" or "person-environment relationship". Unlike the mood, emotion is triggers response tendencies like facial
