Definitions:

Stimulus Generalization

the tendency for the conditioned response to be elicited by stimuli that are similar but not identical to the conditioned stimulus.

Conditioned Inhibition

The permanent inhibition of a specific behavior as a result of the continued failure of that response to reduce the drive state; alternatively, a stimulus (CS2) may develop the ability to suppress the response to another stimulus (CS1) when the CS1 is paired with a UCS and the CS2 is presented without UCS.

Excitatory Strength

The level of potential or ability of a stimulus to produce a response or a desired behavioral effect.

Drive State

A psychological state that motivates an organism to satisfy a physiological need, such as hunger or thirst.
