The stimulus-response model explains social behavior by viewing every social act as a response to the preceding act of another individual. Within this framework, social interaction is understood as a sequence of verbal and nonverbal signals where one person's behavior serves as the stimulus that evokes a response from another.1

This model is rooted in stimulus-response theory, which posits that behavior is shaped by interactions between stimuli and the responses they elicit. In social contexts, this process is often influenced by operant conditioning, where behavior is modified by the consequences or reinforcement (rewards) that follow an action. By manipulating these contingencies, social behavior can be influenced and shifted into predictable patterns.23

While the stimulus-response model is considered a helpful tool for analyzing social interaction, it is generally viewed as incomplete. Other perspectives suggest that social behavior is more complex, involving goal-directed motor skills modified by feedback, or that it functions similarly to the rules of a language or the strategic exchanges found in game theory.1
