The stimulus–response model is a conceptual framework in psychology that describes how individuals react to external stimuli.According to this model, an external stimulus triggers a reaction in an organism, often without the need for conscious thought.
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
Guthrie's theory required that the presentation of punishment happen while the stimulus is still around. He did warn that if the punishment did not stop the undesirable response or if it was not presented in the presence of the stimulus the punishment could actually strengthen the undesired response.
In the theory of classical conditioning, unconditioned stimulus (US) is a stimulus that unconditionally triggers an unconditioned response (UR), while conditioned stimulus (CS) is an originally irrelevant stimulus that triggers a conditioned response (CR). Ivan Pavlov's dog experiment is a well-known experiment that illustrates these terms.
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
Estes proposed a model of learning that he called Stimulus Sampling Theory (SST). SST is a probabilistic model that provides a statistical explanation of how we learn a stimulus-response association in a single trial, but require more stimulus-response repetitions to build an evident unit of learning.

According to the stimulus-response theory, the rat has learned to simply move to the right in the A to B trials, so if the new starting point was C, the rat would go to D. In contrast, Tolman's cognitive map explanation predicted the rat would return to point B even if starting at the new point, C.
The James–Lange theory hypothesises that stimuli trigger physiological response which is experienced as emotion. The James–Lange theory (1964) is a hypothesis on the origin and nature of emotions and is one of the earliest theories of emotion within modern psychology.
