win–stay, lose–shift strategy

in discrimination learning, a mental or behavioral strategy in which an organism continues to give the same response as long as it is being rewarded for doing so but changes the response once it is no longer being rewarded. The opposite win–shift, lose–stay strategy may also be seen: An organism changes responses when rewarded and maintains the response when not rewarded.

anticholinergic effects

side effects that are characteristic of anticholinergic drugs and are also associated with other agents (e.g., tricyclic antidepressants, monoamine oxidase inhibitors) that exert antagonist effects at muscarinic receptors. They include dry mouth, blurred vision, urinary hesitancy or retention, and constipation. Similar antagonistic effects may occur at nicotinic receptors as well. Depending on the specific receptors involved, these effects may also be called antimuscarinic effects or antinicotinic effects.
