What is the reflex consisting of an antecedent stimulus and the response behavior that it elicits?

• A. Temporal locus
• B. Stimulus response
• C. Stimulus control
• D. Topography

Answer: (B)

Stimulus-response describes the basic reflex where an antecedent stimulus directly elicits a specific response. In this relation, the cue triggers the behavior with little or no mediation. This is what defines the reflex: the antecedent and the corresponding response it evokes. The other terms describe different aspects: temporal locus is about when the response occurs relative to the stimulus; stimulus control refers to a stimulus regulating the probability of the response; topography concerns the outward form of the response. For example, a bell signaling a trained dog to salivate illustrates an S-R reflex, where the bell is the antecedent and salivation is the response.
