Spontaneous recovery of excitation and inhibition.
29 Jun 2009 
In two conditioned suppression experiments with rats as subjects, the authors examined two classes of accounts of spontaneous recovery of excitation and inhibition. One view suggests that spontaneous recovery occurs due to greater temporal ...

Attentional and error-correcting associative mechanisms in classical conditioning.
29 Jun 2009 R. A. Rescorla (2000, Rescorla, 2001, Rescorla, 2002) reported that the associative changes undergone by 2 conditioned stimuli that are reinforced or not reinforced in compound depend on their initial associations. The results contradict the ...

Early maternal separation increases symptoms of activity-based anorexia in male and female rats.
29 Jun 2009 Running activates the hypothalamic-pituitary-adrenal (HPA) axis, increasing the release of stress hormones known to exert anorexic effects. HPA axis reactivity is strongly influenced by early postnatal manipulations, including removal of pups from ...

29 Jun 2009 Some studies of nonhuman animals' metacognitive capacity encourage competing low-level, behavioral descriptions of trial-decline responses by animals in uncertainty-monitoring tasks. To evaluate the force of these behavioral descriptions, the ...

Potentiation and overshadowing in Pavlovian fear conditioning.
29 Jun 2009 The present experiments addressed a fundamental discrepancy in the Pavlovian conditioning literature concerning responding to a target cue following compound reinforced training with another cue of higher salience. Experiment 1 identified one ...

Resistance to change within heterogeneous response sequences.
29 Jun 2009 Three experiments investigated how instrumental and Pavlovian contingencies contribute to resistance to change (RTC) in different ordinal response positions within heterogeneous response sequences in pigeons. RTC in the initial and terminal response ...

29 Jun 2009 Animal findings have highlighted the modulatory role of phasic dopamine (DA) signaling in incentive learning, particularly in the acquisition of reward-related behavior. In humans, these processes remain largely unknown. In a recent study, we ...

A neutral cue facilitates detection of a visual target by modulating attention.
14 Jun 2009 
Twelve rats were trained to perform a two-choice visual detection task in which a right or left light was presented and the animals were required to press the lever located under the illuminated light for a food reward. In seventy percent of the ...

Gender differences in delay-discounting under mild food restriction.
6 Jun 2009 Impulsivity, a core symptom of attention-deficit hyperactivity disorder (ADHD), is tested in animal models by delay-discounting tasks. So far, mainly male subjects have been used in this paradigm at severe levels of food restriction. Here we studied ...

30 May 2009 The aims of this study were to assess whether voucher magnitude improved cocaine abstinence and retention in an outpatient treatment for cocaine dependence, and to determine the effectiveness of a contingency management intervention in a European ...
