Multiple Systems for the Motivational Control of Behavior and Associated Neural Substrates in Humans

Abstract

In this chapter, we will review evidence about the role of multiple distinct systems in driving the motivation to perform actions in humans. Specifically, we will consider the contribution of goal-directed action selection mechanisms, habitual action selection mechanisms and the influence of Pavlovian predictors on instrumental action selection. We will further evaluate evidence for the contribution of multiple brain areas including ventral frontal and dorsal cortical areas and several distinct parts of the striatum in these processes. Furthermore, we will consider circumstances in which adverse interactions between these systems can result in the decoupling of motivation from incentive valuation and performance.
