Perceptual learning in human and nonhuman animals: a search for common ground.

29 Apr 2009 Perceptual learning has been extensively studied in both human and nonhuman animals, but the two lines of research have, for the most part, developed independently, addressing seemingly rather different issues by rather different methods. It has ...

Roles of attention in perceptual learning from perspectives of psychophysics and animal learning.

29 Apr 2009 The role of attention in perceptual learning has been a topic of controversy. Sensory psychophysicists/physiologists and animal learning psychologists have conducted numerous studies to examine this role; but because these two types of researchers ...

Varieties of perceptual learning.

29 Apr 2009 Although most studies of perceptual learning in human participants have concentrated on the changes in perception assumed to be occurring, studies of nonhuman animals necessarily measure discrimination learning and generalization and remain agnostic ...

Scopolamine induced deficits in a battery of rat cognitive tests: comparisons of sensitivity and specificity.

29 Apr 2009 Despite much research, the cognitive effects of scopolamine hydrobromide, a cholinergic antagonist, remain controversial. Scopolamine affects multiple systems each of which can impact behavior. One way to tease apart the effects of the drug is to ...

The neuropharmacological substrates of nicotine reward: reinforcing versus reinforcement-enhancing effects of nicotine.

29 Apr 2009 Compulsive nicotine use is thought to be maintained by the acute reinforcing effects of nicotine and the reinforcement-enhancing effects of nicotine, in addition to the negative consequences of nicotine abstinence. Nicotine self-administration and ...

Recognition ROCs are curvilinear-or are they? On premature arguments against the two-high-threshold model of recognition.

29 Apr 2009 Recent reviews of recognition receiver operating characteristics (ROCs) claim that their curvilinear shape rules out threshold models of recognition. However, the shape of ROCs based on confidence ratings is not diagnostic to refute threshold ...

Positive reinforcement training in rhesus macaques-training progress as a result of training frequency.

29 Apr 2009 Positive reinforcement training (PRT) efficiency was examined as a function of training frequency in 33 pair- or triple-housed female rhesus macaques. The animals were trained three times a week, once a day or twice a day, using PRT and a clicker as ...

Rescue of Abeta(1-42)-induced memory impairment in day-old chick by facilitation of astrocytic oxidative metabolism: implications for Alzheimer's disease.

29 Apr 2009 Administration of small oligomeric beta-amyloid (Abeta)(1-42) 45 min before one-trial bead discrimination learning in day-old chicks abolishes consolidation of learning 30 min post-training (Gibbs et al. Neurobiol. Aging, in press). Administration ...

Model-based reinforcement learning under concurrent schedules of reinforcement in rodents.

27 Apr 2009 Reinforcement learning theories postulate that actions are chosen to maximize a long-term sum of positive outcomes based on value functions, which are subjective estimates of future rewards. In simple reinforcement learning algorithms, value ...

Effect of concurrent saccharin intake on ethanol consumption by high-alcohol-drinking (UChB) rats.

26 Apr 2009 This study examined the effect of concurrent presentation of a highly palatable saccharin solution on ethanol consumption during the acquisition or maintenance of ethanol drinking by high-alcohol-drinking (UChB) rats. Rats were exposed to ethanol ...
