Generalization decrement is when the response to other stimuli is less than that to S+ itself. An example of this could be a dog being trained to respond to a specific tone, but not responding as strongly to similar tones.

Peak shift is when responding may be greater to a stimulus other than S+ (S’). It relates to discrimination learning because it can lead to the animal choosing the more "extreme" stimulus, rather than the one intended to be the correct response.

Transposition is when S’ may be chosen instead of S+ in a discrimination between S+ and S-. It relates to discrimination learning because it can affect the animal's ability to correctly discriminate between stimuli.

Transfer along a continuum (TAC) is when training an easy discrimination on a dimension can help the animal acquire a difficult one. It can be useful in discrimination learning because it can help the animal develop better discrimination abilities overall.

The continuity vs. non-continuity theory is a classic theoretical issue in discrimination learning. Krechevsky and Lashley's non-continuity theories suggest that learning occurs suddenly, while the Hull-Spence continuity theory suggests that learning occurs gradually.

Lecture 5 of PSY2304 focuses on discrimination and generalization in the biological basis of behavior.

Generalization occurs when a response occurs to stimuli that are physically similar to S+ but not identical to it. It differs from discrimination, which is the ability to distinguish between different stimuli.

Sharpening of generalization gradients occurs when an S- is introduced. It is related to S- because the introduction of this stimulus can make the animal more able to discriminate between stimuli.

A potential limitation of the Hull-Spence continuity theory is that it may not account for sudden changes in behavior that can occur in some situations.

The concept of generalization can be applied in real-world settings by using it to help individuals learn to respond to a range of stimuli, rather than just one specific one. This can be useful in education or therapy, where the goal is to help individuals generalize their learning to new situations.
