The learning curve: Implications of a quantitative analysis
TL;DR: The negatively accelerated, gradually increasing learning curve is an artifact of group averaging in several commonly used basic learning paradigms (pigeon autoshaping, delay-and trace-eye-blink conditioning in the rabbit and rat, autoshaped hopper entry in the rat, plus maze performance and water maze performance in the mouse) The learning curves for individual subjects show an abrupt, often steplike increase from the untrained level of responding to the level seen in the well trained subject as discussed by the authors.

TL;DR: It is found that a subtle decrease in MD activity is sufficient to trigger selective impairments in prefrontal-dependent cognitive tasks and could contribute to the cognitive symptoms observed in schizophrenia.
Journal ArticleDOI
Mice with Chronically Elevated Dopamine Exhibit Enhanced Motivation, but not Learning, for a Food Reward
TL;DR: Motivation to work, but not learning, for a food reward appears to be under the critical influence of tonic dopaminergic activity in discrete brain areas relevant for a reward-directed behavior.
Journal ArticleDOI
Temporal maps and informativeness in associative learning
TL;DR: Evidence that learning depends, instead, on learning a temporal map is reviewed, which yields a quantitative account of the heretofore undefined, but theoretically crucial, concept of temporal pairing, an account in quantitative accord with surprising experimental findings.
