Question

Quizplus · Accepted Answer

Sign stimuli initiate fixed action patterns, which are innate, highly stereotypical behaviors that occur in response to specific stimuli. These are not learned behaviors, hence they are not associated with classical conditioning (A) or operant behaviors (D). While organisms may approach sign stimuli, this is not the defining characteristic of sign stimuli (B).
