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. This might be part of complex, interpersonal communication.
Antecedent stimuli (paired with reinforcing consequences) activate centers of the brain involved in motivation, while antecedent stimuli that have been paired with punishing consequences activate brain centers involved in fear.
