Stimulus–response models are applied in international relations, [1] psychology, [2] risk assessment, [3] neuroscience, [4] neurally-inspired system design, [5] and many other fields. Pharmacological dose response relationships are an application of stimulus-response models.
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.
The stimulus–response model emphasizes the relation between stimulus and behavior rather than an animal's internal processes (i.e., in the nervous system). [2] In experimental psychology, a stimulus is the event or object to which a response is measured. Thus, not everything that is presented to participants qualifies as stimulus.
The link between stimulus and response can be studied from two opposite points of view. Neural encoding refers to the map from stimulus to response. The main focus is to understand how neurons respond to a wide variety of stimuli, and to construct models that attempt to predict responses to other stimuli.
Without conditioning, there is already a relationship between the unconditioned stimulus and the unconditioned response. When a second stimulus is paired with the unconditioned stimulus, the response becomes associated with both stimuli. The secondary stimulus is known as the conditioned stimulus and elicits a conditioned response. [8] The ...
Generalisation is when an association between a stimulus and a response will be generalised or applied superficially to a stimulus that is similar to the initial one. [15] To expand upon this further, when making a learned association concerning a stimulus A, the strength of that association can be dispensed across a number of elements that ...
The stimulus–response compatibility is known to also affect the choice reaction time for the Hick–Hyman law. This means that the response should be similar to the stimulus itself (such as turning a steering wheel to turn the wheels of the car). The action the user performs is similar to the response the driver receives from the car.
It is often considered to supersede the Weber–Fechner law, which is based on a logarithmic relationship between stimulus and sensation, because the power law describes a wider range of sensory comparisons, down to zero intensity. [1] The theory is named after psychophysicist Stanley Smith Stevens (1906–1973).
