“…For example, do posterior alpha increases reflect fluctuations in attention whereas fm-theta increases reflect more prolonged deteriorations? Sustained attention is strongly enhanced by motivation [88]. How does motivation affect the power of attention-related cortical oscillations?…”

“…From the biological, effort suggests neural factors associated with basic drives and emotional states (see . Within cognitive neuroscience, effort relates directly to complexity of stimulus processing (Kohl, Wylie, Genova, Hillary, & Deluca, 2009) and levels of motivation (Bonnefond, Doignon-Camus, Hoeft, & Dufour, 2011;Harsay et al, 2011). In forensic and applied neuropsychology, the effort term suggests some intention on the subject's part where poor effort may be equated with malingering (see .…”

AbstractSymptom validity testing (SVT) has become a major theme of contemporary neuropsychological research. However, many issues about the meaning and interpretation of SVT findings will require the best in research design and methods to more precisely characterize what SVT tasks measure and how SVT test findings are to be used in neuropsychological assessment. Major clinical and research issues are overviewed including the use of the “effort” term to connote validity of SVT performance, the use of cut-scores, the absence of lesion-localization studies in SVT research, neuropsychiatric status and SVT performance and the rigor of SVT research designs. Case studies that demonstrate critical issues involving SVT interpretation are presented. (JINS, 2012,18, 1–11)

“…Assuming subjects have no additional incentive to maintain consistently high performance, 14 studies have shown that task performance and/or behavioral adjustment generally declines with increasing time spent performing a task 15, 16, 17, 18 —findings interpreted as reflecting mental fatigue. Notably, this time-on-task performance erosion often occurs in conjunction with disengagement of the anterior cingulate cortex (ACC), as indicated by reductions in the scalp-recorded error-related negativity 15, 16, 18 (an event-related potential thought to be generated by the ACC, 19 especially by its more cognitive dorsal (dACC) subregion, 20 which spikes during error, negative feedback or high response conflict 21 ).…”

Dopaminergic involvement during mental fatigue in health and cocaine addiction

et al. 2012

Dopamine modulates executive function, including sustaining cognitive control during mental fatigue. Using event-related functional magnetic resonance imaging (fMRI) during the color-word Stroop task, we aimed to model mental fatigue with repeated task exposures in 33 cocaine abusers and 20 healthy controls. During such mental fatigue (indicated by increased errors, and decreased post-error slowing and dorsal anterior cingulate response to error as a function of time-on-task), healthy individuals showed increased activity in the dopaminergic midbrain to error. Cocaine abusers, characterized by disrupted dopamine neurotransmission, showed an opposite pattern of response. This midbrain fMRI activity with repetition was further correlated with objective indices of endogenous motivation in all subjects: a state measure (task reaction time) and a trait measure (dopamine D2 receptor availability in caudate, as revealed by positron emission tomography data collected in a subset of this sample, which directly points to a contribution of dopamine to these results). In a second sample of 14 cocaine abusers and 15 controls, administration of an indirect dopamine agonist, methylphenidate, reversed these midbrain responses in both groups, possibly indicating normalization of response in cocaine abusers because of restoration of dopamine signaling but degradation of response in healthy controls owing to excessive dopamine signaling. Together, these multimodal imaging findings suggest a novel involvement of the dopaminergic midbrain in sustaining motivation during fatigue. This region might provide a useful target for strengthening self-control and/or endogenous motivation in addiction.
