Definition. In neuroscience, the reward system is a collection of brain structures and neural pathways that are responsible for reward-related cognition, including associative learning (primarily classical conditioning and operant reinforcement ), incentive salience (i.e., motivation and "wanting", desire, or craving for a reward), and ...
In neuroscience, the default mode network ( DMN ), also known as the default network, default state network, or anatomically the medial frontoparietal network ( M-FPN ), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.
Cognitive evaluation theory ( CET) [ 1] is a theory in psychology that is designed to explain the effects of external consequences on internal motivation. Specifically, CET is a sub-theory of self-determination theory that focuses on competence and autonomy while examining how intrinsic motivation is affected by external forces in a process ...
In behavioral psychology, reinforcement refers to consequences that increase the likelihood of an organism's future behavior, typically in the presence of a particular antecedent stimulus. [ 1] For example, a rat can be trained to push a lever to receive food whenever a light is turned on. In this example, the light is the antecedent stimulus ...
Motivation crowding theory is the theory from psychology and microeconomics suggesting that providing extrinsic incentives for certain kinds of behavior—such as promising monetary rewards for accomplishing some task—can sometimes undermine intrinsic motivation for performing that behavior. The result of lowered motivation, in contrast with ...
Reinforcement sensitivity theory ( RST) proposes three brain-behavioral systems that underlie individual differences in sensitivity to reward, punishment, and motivation. While not originally defined as a theory of personality, the RST has been used to study and predict anxiety, impulsivity, and extraversion. [ 1]
Insufficient justification. Insufficient justification is an effect studied in the discipline of social psychology. It states that people are more likely to engage in a behavior that contradicts the beliefs they hold personally when offered a smaller reward compared to a larger reward. [1] The larger reward minimizes the cognitive dissonance ...
Overjustification is an explanation for the phenomenon known as motivational "crowding out". The overall effect of offering a reward for a previously unrewarded activity is a shift to extrinsic motivation and the undermining of pre-existing intrinsic motivation. Once rewards are no longer offered, interest in the activity is lost; prior ...
