Antecedent (behavioral psychology)

Wikipedia Open wikipedia design.

An antecedent is a stimulus that cues an organism to perform a learned behavior. When an organism perceives an antecedent stimulus, it behaves in a way that maximizes reinforcing consequences and minimizes punishing consequences.

Antecedent stimuli that have been paired with reinforcing consequences activate centers of the brain involved in motivation,[1] while antecedents that have been paired with punishing consequences activate brain centers involved in fear.[2]
