A stimulus-location effect in contingency-governed, but not rule-based, discrimination learning.

Rule-Governed Versus Contingency-Shaped Self-Control in Preschool Children

Web-based programmed instruction: evidence of rule-governed learning

Seventeen graduate students in two classes worked on a web-based programmed instruction tutoring system as the first technical exercise in a Java programming course. The system taught a simple Java applet to display a text string in a browser window on the world wide web. Students completed tests of near transfer and far transfer before and after using the tutor and again after a lecture on the...

Stress impairs spatial but not early stimulus-response learning.

Recent evidence indicates that stress modulates multiple memory systems, favoring caudate nucleus-based stimulus-response learning at the expense of hippocampus-based spatial learning. Whether this is due to a facilitating effect of stress on stimulus-response learning, an impairing effect on spatial learning, or both, is not known. To answer this question, mice were either subjected to restrai...

Hippocampal theta activity is selectively associated with contingency detection but not discrimination in rabbit discrimination-reversal eyeblink conditioning.

The relative power of the hippocampal theta-band ( approximately 6 Hz) activity (theta ratio) is thought to reflect a distinct neural state and has been shown to affect learning rate in classical eyeblink conditioning in rabbits. We sought to determine if the theta ratio is mostly related to the detection of the contingency between the stimuli used in conditioning or also to the learning of mor...

Dopaminergic medication impairs feedback-based stimulus-response learning but not response selection in Parkinson's disease

Cognitive dysfunction is a feature of Parkinson's Disease (PD). Some cognitive functions are impaired by dopaminergic medications prescribed to address the movement symptoms that typify PD. Learning appears to be the cognitive function most frequently worsened by dopaminergic therapy. However, this result could reflect either impairments in learning (i.e., acquisition of associations among stim...
