Relations between posttraining reinforcer devaluation and Pavlovian-instrumental transfer were examined in 2 experiments. When a single reinforcer was used, extended training of the instrumental response increased transfer but reduced devaluation effects. When multiple instrumental reinforcers were used, both reinforcer-specific transfer and devaluation effects were less influenced by the amoun...

The present research aimed at determining the role played by the amygdala in reward devaluation using transient inactivation induced by lidocaine microinfusions into the centromedial region. Two situations involving reward devaluation were tested in rats: consummatory successive negative contrast (cSNC) and anticipatory negative contrast (ANC). In cSNC, rats exposed to a downshift from 32% to 4...

Choice between goal-directed actions is determined by the relative value of their consequences. Such values are encoded during incentive learning and later retrieved to guide performance. Although the basolateral amygdala (BLA) and the gustatory region of insular cortex (IC) have been implicated in these processes, their relative contribution is still a matter of debate. Here we assessed whethe...

Stock returns over the two years surrounding 24 currency devaluations are examined. Using bootstrapped distributions, returns preceding the devaluation are shown to be significantly below normal, in both dollar and local currency terms. Most of the downturn, however, occurs well before the month of the devaluation. Returns following a devaluation are more normal. While industry and company spec...

This work tested the hypothesis that persons who are more committed to their relationships devalue potential alternative partners, especially attractive and threatening alternatives. In Study 1, a longitudinal study, perceived quality of alternatives decreased over time among stayers but increased for leavers. In Study 2, a computer dating service paradigm, more committed persons exhibited grea...

In outcome-selective Pavlovian-to-instrumental transfer (PIT), stimuli that are predictive of specific outcomes prime instrumental responses that are associated with these outcomes. Previous human studies yielded mixed evidence in respect to whether the PIT effect is affected by a posttraining devaluation of an outcome, with the PIT effect being preserved after a devaluation of a primary reinfo...

AIMS To investigate the mediating role of attentional bias for alcohol cues on alcohol-seeking following devaluation of alcohol. DESIGN Between subject. SETTING Eye-tracking laboratory at the University of Liverpool. PARTICIPANTS Student social drinkers (n = 64). MEASUREMENTS An operant choice task in which participants chose between simultaneously presented alcohol and non-alcohol drin...
