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).
The controlling effects of stimuli are seen in quite diverse situations and in many aspects of behavior. For example, a stimulus presented at one time may control responses emitted immediately or at a later time; two stimuli may control the same behavior; a single stimulus may trigger behavior A at one time and behavior B at another; a stimulus may control behavior only in the presence of ...
The tact is said to be capable of generic extension. Generic extension is essentially an example of stimulus generalization. The novel stimulus contains all of the relevant features of the original stimulus. For example, we may see a red car and say "car" as well as see a white car and say "car".
In behavioral psychology (i.e., classical and operant conditioning), a stimulus constitutes the basis for behavior. [2] 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 ...
Most behavior is under stimulus control. Several aspects of this may be distinguished: Discrimination typically occurs when a response is reinforced only in the presence of a specific stimulus. For example, a pigeon might be fed for pecking at a red light and not at a green light; in consequence, it pecks at red and stops pecking at green.
Stimulus generalization applies beyond food tastes and aversion. Trauma and aversive events of all kinds create aversion and generalizations to other events. And like taste aversion, the generalization may or not be conscious. Stimulus generalization is a factor in "superstitious behavior", racism and prejudice of all kinds.
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
There are both similarities and differences between the terms "stimulus generalization" and "generality of a functional relationship." Stimulus generalization is the description of the fact that an organism behaves in a similar way to similar stimuli, and that the more different the stimuli, the more different the behavior. The generality of a ...
