Human pavlovian-instrumental transfer.
The vigor with which a participant performs actions that produce valuable outcomes is subject to a complex set of motivational influences. Many of these are believed to involve the amygdala and the nucleus accumbens, which act as an interface between limbic and motor systems. One prominent class of influences is called pavlovian-instrumental transfer (PIT), in which the motivational characteris...
متن کاملAvoidance-based human Pavlovian-to-instrumental transfer.
The Pavlovian-to-instrumental transfer (PIT) paradigm probes the influence of Pavlovian cues over instrumentally learned behavior. The paradigm has been used extensively to probe basic cognitive and motivational processes in studies of animal learning. More recently, PIT and its underlying neural basis have been extended to investigations in humans. These initial neuroimaging studies of PIT hav...
متن کاملAssociative Structures in Pavlovian and Instrumental Conditioning
In the most basic of conditioning procedures, the experimental subject (usually an animal, but sometimes a human participant) experiences two events in close temporal conjunction. In Pavlovian conditioning, one stimulus (the unconditioned stimulus, US) occurs along with (usually shortly after) the presentation of some other (the conditioned stimulus, CS); in instrumental conditioning, a stimulu...
متن کاملPavlovian to instrumental transfer of control in a human learning task.
Pavlovian learning tasks have been widely used as tools to understand basic cognitive and emotional processes in humans. The present studies investigated one particular task, Pavlovian-to-instrumental transfer (PIT), with human participants in an effort to examine potential cognitive and emotional effects of Pavlovian cues upon instrumentally trained performance. In two experiments, subjects fi...
متن کاملStress Transiently Affects Pavlovian-to-Instrumental Transfer
Stress has a strong impact in the brain, impairing decision-making processes as a result of changes in circuits involving the prefrontal and orbitofrontal cortices and the striatum. Given that these same circuits are key for action control and outcome encoding, we hypothesized that adaptive responses to which these are essential functions, could also be targeted by stress. To test this hypothes...
