In this study we examined whether the effects of mental fatigue on
behaviour are due to reduced action monitoring as indexed by the
error related negativity (Ne/ERN), N2 and contingent negative variation
(CNV) event-related potential (ERP) components. Therefore, we had
subjects perform a task, which required a high degree of action monitoring,
continuously for 2 h. In addition we tried to relate the observed
behavioural and electrophysiological changes to motivational processes
and individual differences.
Changes in task performance due to fatigue were accompanied by a decrease
in Ne/ERN and N2 amplitude, reflecting impaired action monitoring,
as well as a decrease in CNV amplitude which reflects reduced response
preparation with increasing fatigue. Increasing the motivational
level of our subjects resulted in changes in behaviour and brain
activity that were different for individual subjects. Subjects that
increased their performance accuracy displayed an increase in Ne/ERN
amplitude, while subjects that increased their response speed displayed
an increase in CNV amplitude. We will discuss the effects prolonged
task performance on the behavioural and physiological indices of
action
monitoring, as well as the relationship between fatigue, motivation
and individual differences.
