Motivation; the result of human evolutionary history or learned through reinforcement? Motivation is the common desire and willingness that a person possesses to carry out a behavior. It is precisely through motivation that a human being achieves his goals and ambitions. The push of a motive, which is an internal character involved in pushing an individual's impulse on the path to a desired end, or the pull of an incentive, a valued feature of the environment that attracts an individual towards itself, such as stated by Deckers (2010), it is what persuades a mental or physical action to help acquire a particular incentive or goal. Since both physical and psychological knowledge, skills and energy are required to determine behavior, the emotional aspect of motivation also plays an important role. It is through a person's emotions that an adaptive process occurs in the evaluation of the overall mental, physical and physical characteristics of the incentive which also contribute to motivation. Investigation into the question of motivational origins and learned responses, further "pushes" for the analysis of sources in motivation control. Motivation has two main sources involved in push and pull stimulus which include an internal and external quality of mind and character. Internal dispositions include two types of variables involved in motivational enthusiasm; first, there are the biological variables involving the brain and nervous system and second, the psychological variable involving an individual's mental needs. Biological and psychological variables are conceptually linked through reductionism and emergence: reductionism is the principle that the concepts of psychology and can be explained by reducing them to a principle...... at the center of paper sequences involved in achieving a reason or a purpose of choice, the adoption of instrumental behaviors or motivated activities are aimed at achieving objectives. Therefore, since motivation is linked to the emotional and biopsychological characteristics of most human beings, the question of history or reinforcement is ultimately the history and reinforcement that incites motivation. It's an aspect of life like no other, the inspiration that keeps us at the top of the food chain through the incomparable drive to survive and succeed. Works CitedDeckers, L. (2010).
