Examples of discrimination learning in everyday life can include grocery shopping, determining how to decipher between the types of bread or fruit, being able to tell similar stimuli apart, differentiating between different parts while listening to music, or perhaps deciphering the different notes and chords being played.
A simple discrimination learning procedure is one in which a subject learns to associate one stimulus, S+ (positive stimulus), with reinforcement (e.g. food) and another, S− (negative stimulus), with extinction (e.g. absence of food). For example, a pigeon can learn to peck a red key (S+), and avoid a green key (S−).
The differential outcomes effect (DOE) is a theory in behaviorism, a branch of psychology, that shows that a positive effect on accuracy occurs in discrimination learning between different stimuli when unique rewards are paired with each individual stimulus.
For example, shielding one's eyes from sunlight terminates the (aversive) stimulation of bright light in one's eyes. (This is an example of negative reinforcement, defined above.) Behavior that is maintained by preventing a stimulus is called "avoidance," as, for example, putting on sun glasses before going outdoors.
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 ...
When a subject shows habituation to a new stimulus that is similar to the original stimulus but not to a stimulus that is different from the original stimulus, then the subject is showing stimulus discrimination. (For example, if one was habituated to the taste of lemon, their responding would increase significantly when presented with the ...
An important part of learning is knowing when not to generalize, which is called discrimination learning. Were it not for discrimination learning, humans and animals would struggle to respond correctly to different situations. [15] For example, a dog may be trained to come to its owner when it hears a whistle.
Spontaneous recovery is associated with classical conditioning, a learning process in which an organism learns to associate a neutral stimulus with a stimulus that produces an unconditioned response. As a result, the previously neutral stimulus comes to produce its own response, which is usually similar to that produced by the unconditioned ...
