word-frequency study

a study in which the frequency of to-be-remembered words is manipulated to investigate the effect of this variable on later memory. Typically, in studies of free recall, higher frequency words are better remembered, but in studies of recognition memory, lower frequency words are better remembered. See also frequency judgment.

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.
