which these fields have developed independently of one another. From one perspective, this is not surprising. 3 Neuron Cell Press Each field seeks to understand behavior at a different level of analysis, and sometimes with different inten-Cambridge, Massachusetts 02138 tions.

متن کاملLearning, Reward, and Decision Making.
In this review, we summarize findings supporting the existence of multiple behavioral strategies for controlling reward-related behavior, including a dichotomy between the goal-directed or model-based system and the habitual or model-free system in the domain of instrumental conditioning and a similar dichotomy in the realm of Pavlovian conditioning. We evaluate evidence from neuroscience suppo...
متن کاملNeuroethology of reward and decision making
Ethology, the evolutionary science of behaviour, assumes that natural selection shapes behaviour and its neural substrates in humans and other animals. In this view, the nervous system of any animal comprises a suite of morphological and behavioural adaptations for solving specific information processing problems posed by the physical or social environment. Since the allocation of behaviour oft...
متن کاملDecision Making and Reward in Frontal Cortex
Patients with damage to the prefrontal cortex (PFC)--especially the ventral and medial parts of PFC--often show a marked inability to make choices that meet their needs and goals. These decision-making impairments often reflect both a deficit in learning concerning the consequences of a choice, as well as deficits in the ability to adapt future choices based on experienced value of the current ...
متن کاملImpulsivity and Rapid Decision-Making for Reward
Impulsivity is a feature of many brain disorders. Although often defined as the predisposition to act with an inadequate degree of deliberation, forethought, or control, it has proven difficult to measure. This may in part be due to the fact that it is a multifaceted construct, with impulsive decisions potentially arising as a result of a number of underlying mechanisms. Indeed, a "functional" ...
