avoidance gradient

the variation in the strength of a drive as a function of the organism’s proximity to an aversive stimulus. For example, a rat’s withdrawal behavior increases in intensity as it nears a feared stimulus (e.g., an electric shock). The avoidance gradient appears steeper than the approach gradient. [originally proposed by Neal E. Miller]
