Generalizations are summary statements of relationships between concepts, summary statements of cause and effect, or summary statements of predictions of future relationships. Generalizations are powerful as they provide a way to consolidate information to make it more usable and easier to remember. Laws, principals, and theories are all kinds of generalizations. These generalizations require the connection of concepts by a relationship.
Stimulus Generalization. Stimulus generalization is the tendency of a subject to respond to a stimulus or a group of stimuli similar but not identical to the original CS. For example, a subject may initially make the desired response when exposed to any sound (that is, to a generalized stimulus) rather than making such a response only to a specific sound. Such generalization can occur in both classical and operant conditioning (if a CS is used).
