- Abstract
- This thesis, which is composed of 3 chapters, aimed to better understand mental fatigue (MF) in healthy individuals by investigating whether it is the consequence of a temporary degradation of cognitive resources or altered motivational states which impede the recruitment of otherwise unaltered cognitive resources. The first, introductory, chapter subdivided into 3 parts provides a comprehensive review of the MF literature. Part 1 focuses on the conceptualization and operationalization of MF. In part 2, those theories are described that support either the resource- or altered motivation-based view of MF. Part 3 deals with empirical studies which address the latter, motivation-related, view. Chapter 2 contains two original experimental studies wherein the influential hypothesis that MF results from an alteration of motivational processes, particularly in the basal ganglia, was tested by using multidimensional measurements. In light of the evidences, it is more plausible that MF ensues from an alteration in brain resources. In Chapter 3, recent proposals for the nature of these resources are discussed.
