The
venerable concept of drive (e.g., Bindra, 1968; Hull, 1952) remains an
important component of the motivational picture as an aroused internal
state that both invigorates mental and motor activity and modulates
the value of drive-related incentives. However, even Hull’s (1952)
theory supplemented it with incentive as a determinant of motivation,
and subsequent evidence (e.g., Bindra, 1968; Black, 1965, 1968, 1969,
1976; Black & Cox, 1973; Klinger, 1971; Tomkins, 1962) supported
the need for additional factors, or even just different factors, for
motivational prediction of everyday human behavior. Following
Bindra’s analysis, drive may be considered to perform two functions:
to activate and to modify, even if only temporarily, the values of
various incentives. Thus, both rats and people, when hungry, become
more restless and give heightened priority to getting something to
eat.
