Stimulus generalization: the procedure of reinforcing a response in the presence of a stimulus or situation and the effect of the response becoming more probable in the presence of another stimulus or situation. In other words, instead of discriminating between two stimuli and responding differentially to them, an individual responds in the same way to two different stimuli: thus, stimulus generalization is the opposite of stimulus discrimination. Learned stimulus generalization in spite of no physical similarity. Stimulus equivalence class: a set of completely dissimilar stimuli (i. e. , have no common stimulus element) that an individual has learned to group or match together or respond to in the same way. Like common element stimulus classes, a stimulus equivalence class is also a concept.
