Within-subject differences in degree of delay discounting as a function of order of presentation of hypothetical cash rewards.

17 Mar 2009 Procedural variants in estimating delay discounting (DD) have been shown to yield significant differences in estimated degree of DD as well as variations in individual patterns of choice. For example, a recent study found significantly different ...

Flavor-nutrient learning is less rapid with fat than with carbohydrate in rats.

16 Mar 2009 Flavor-nutrient learning occurs when the post-ingestive consequences of a food are associated with its flavor. As a signal of the food's energy density, flavor-nutrient associations have the potential to contribute to the regulation of meal size. ...

Consummatory successive negative and anticipatory contrast effects in inbred Roman rats.

14 Mar 2009 Three experiments were designed to study the performance of female inbred Roman High-(RHA-I) and Low-(RLA-I) Avoidance rats in a consummatory task in which successive negative (cSNC) and anticipatory contrast (cANC) effects were induced by changing ...

Intermodal transfer from a visual to an auditory discrimination using an errorless learning procedure.

12 Mar 2009 Errorless learning is a technique developed by Terrace [Terrace, H.S., 1963a. Discrimination training with and without "errors". J. Exp. Anal. Behav. 6, 1-27] to train stimulus discriminations with few or no errors. In the first replication of the ...

Instrumental outcome devaluation with representation-mediated conditioning.

9 Mar 2009 In three experiments, rats were trained to perform two instrumental behaviours (R1 and R2) in the presence of discriminative stimuli (Sd1 and Sd2, respectively) to obtain a common food outcome (O1). Acquisition of the two discriminations was ...

Dynamic encoding of action selection by the medial striatum.

9 Mar 2009 Successful foragers respond flexibly to environmental stimuli. Behavioral flexibility depends on a number of brain areas that send convergent projections to the medial striatum, such as the medial prefrontal cortex, orbital frontal cortex, and ...

Hippocampal nAChRs mediate nicotine withdrawal-related learning deficits.

8 Mar 2009 Nicotine modulation of learning may contribute to its abuse liability. The role of hippocampal nicotinic acetylcholine receptors (nAChRs) in the effects of acute, chronic and withdrawal from chronic nicotine on learning was assessed via ...

Extinction learning of stimulus reward contingencies: The acute effects of alcohol.

8 Mar 2009 BACKGROUND: Recent theories suggest that extinction is, at least partly, new learning suppressing original associations between a conditioned stimulus and a conditioned response without severing those associations. During extinction alcohol via its ...

Memory impairment induced by IL-1beta is reversed by alpha-MSH through central melanocortin-4 receptors.

7 Mar 2009 Interleukin-1beta (IL-1beta) significantly influences memory consolidation. Treatments that raise the level of IL-1beta in the brain, given after training, impair contextual fear conditioning. The melanocortin alpha-MSH exerts potent ...

Behavioral research in pigeons with ARENA: an automated remote environmental navigation apparatus.

7 Mar 2009 Three experiments established the effectiveness of an Automated Remote Environmental Navigation Apparatus (ARENA) developed in our lab to study behavioral processes in pigeons. The technology utilizes one or more wireless modules, each capable of ...
