Perceived control refers to the conscious process by which an event is determined to be manageable, or more simply put, it can be thought of as the extent to which an individual/organism believes that they have the resources and capability to manage an event. From a neurological perspective, basic research suggests that motivated behaviors are significantly influenced by the controllability of the event through fluctuations of dopamine levels within the mesocorticolimbic system. These biological mechanisms are also associated with affective traits, in which positive affect is believed to facilitate approach behaviors while negative affect appears to promote behavioral avoidance, possibly through modulating levels of dopamine within the mesolimbic systems [1].
