A metabolic measure of mental effort
Biological Psychology, 2004Previous studies have operationalised mental effort via various indices of psychophysiology, particularly cardiovascular measures. Metabolic measures represent a complementary approach wherein mental effort investment is explicitly linked to the process of energy mobilisation.

Mental capacity, mental effort, and cognitive style
Developmental Review, 1983Abstract This study tests the relationship between two theoretical models of human attentional capacity: Pascual-Leone's mental capacity and Kahneman's mental effort. It was found that significant and positive correlations exist between the empirical measures of the above constructs, and the relationship is demonstrated via construct validation by ...

Mental Load, Mental Effort and Attention
1979Many of the concepts introduced into the research on mental load seem to have developed by analogy with those already available in the field of physical workload.

Applied Effort Influence on Mental Workload Measures
2022Some of the variability found in measures of mental workload (see e.g. Singleton et al. 1973; Wierwille and Connor 1983; Steelman-Allen et al. 2011; Casner and Gore 2010) may be due to the effort applied to the task by participants, rather than by the independent variable of interest. If true, capturing and removing the variation due to ‘applied effort’

Urinary dopamine in physical and mental effort
European Journal of Applied Physiology and Occupational Physiology, 1984Dopamine in urine was investigated during three levels of physical stress (at 35%, 50%, and 75% VO2 max.) and three kinds of mental stress (delayed auditory feedback, vigilance task and arithmetic task). A statistically significant increase in excretion of dopamine was found in response to physical exercise and the delayed auditory feedback test.

Mental effort in adolescents with ADHD
International Journal of Psychophysiology, 2016Mental effort plays an important role in theoretical models of ADHD; it is central to both motivational and cognitive-energetic accounts, but it has been underspecified and under-examined empirically. It could however, provide the missing link between task performance of difficult and challenging tasks requiring cognitive control, and the effects of ...

Electroencephalographical Changes during Mental Efforts
Psychiatry and Clinical Neurosciences, 1947Summary Now, to summarize the above statements, in case of mental work such as mental arithmetics the α-wave of -the brain tends to diminish its amplitude in one: hand arid to increase it:; frequency in the other hand. The mode and grade of reaction do not differ thereby from those of sensory stimulation.

On the Energy Cost of Mental Effort
Journal of the History of the Neurosciences, 2006The discovery of the Law of Conservation of Energy in the 1840s had consequences for psychological theory. Does the process of thinking involve a novel form of energy that is not recognized by physical science? E. L. Youmans (1821-1887) argued that "mental operations are dependent upon material changes in the nervous system." Kurd Lasswitz (1848-1910 ...

Prolonged Mental Effort in Losses
This study examines the varying effects of potential losses compared to gains on mental effort and problem-solving performance. Building on prospect theory and previous studies, we hypothesized that individuals would engage in longer effort when faced with potential losses compared to equivalent potential gains, and that this extended effort would ...Carlos Rey +2 more
