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.

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 ...

Making the case for measuring mental effort
Proceedings of the Second Edition of the International Workshop on Experiences and Empirical Studies in Software Modelling, 2012To empirically investigate conceptual modeling languages, subjects are typically confronted with experimental tasks, such as the creation, modification or understanding of conceptual models. Thereby, accuracy, i.e., the amount of correctly performed tasks divided by the number of total tasks, is usually used to assess performance.

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.

A system for remote monitoring of mental effort
2016 IEEE 6th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2016Real-time monitoring of mental effort enables the possibility of dynamically adapting the challenge of a task given to an individual, thereby maintaining the skill-challenge balance. In this paper we propose a remote monitoring system for assessing mental effort or cognitive load using low cost Galvanic Skin Response (GSR) sensor. The variations in the

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.

Mental effort and fatigue as consequences of monotony
Behavioral and Brain Sciences, 2013AbstractKurzban et al. associate mental effort and fatigue with a hypothetical mechanism able to estimate the utilities of possible actions and then select the action with a maximal utility. However, this approach faces fundamental problems. In my opinion, mental effort and fatigue are results of a conflict between the monotony of long-term activities ...

The Influence of Losses on Mental Effort and Performance
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

Tracking intentionalism and the phenomenology of mental effort
Synthese, 2019Most of us are familiar with the phenomenology of mental effort accompanying cognitively demanding tasks, like focusing on the next chess move or performing lengthy mental arithmetic. In this paper, I argue that phenomenology of mental effort poses a novel counterexample to tracking intentionalism, the view that phenomenal consciousness is a matter of ...

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 ...
