Previous 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. The purpose of this study was to contrast cardiovascular variables (heart rate, 0.1 Hz component of heart rate variability) with a metabolic measure (blood glucose) of mental effort. Twenty-nine participants were exposed… Expand

Paper Mentions

The role of working memory capacity in cardiovascular monitoring of cognitive workload
TLDR
It is suggested that working memory capacity (WMC) may play a critical role in determining how individuals react to increased cognitive workload, and negatively predicted subjective ratings of task difficulty as well as task performance. Expand
Blood glucose changes and memory: Effects of manipulating emotionality and mental effort
TLDR
There exists a clear relationship between reduced blood glucose and impaired memory performance during periods of mental effort, however, the relationship between physiological and cognitive processes associated with processing emotional material are more complex. Expand
Mental fatigue impairs physical performance in humans.
TLDR
Experimental evidence is provided that mental fatigue limits exercise tolerance in humans through higher perception of effort rather than cardiorespiratory and musculoenergetic mechanisms. Expand

TLDR
It is argued that upward goal adjustment accounted for the psychophysiological changes observed in the positive feedback condition and led to increased systolic blood pressure reactivity and a suppression of the 0.1Hz component of HRV. Expand
Low Physiological Arousal in Mental Fatigue: Analysis of Heart Rate Variability during Time-on-task, Recovery, and Reactivity
TLDR
The present findings support the low arousal state of mental fatigue and suggest that primarily the vagal components of the HRV spectrum are indicative of fatigue, not only in a fatiguing condition but also if individuals are engaged in a prolonged non-fatiguing activity. Expand
A Systematic Review of Physiological Measures of Mental Workload
TLDR
Most physiological measures used to assess mental workload were found to be able to discriminate changes in MWL, but they were not universally valid in all task scenarios. Expand
Enhanced cardiac vagal tone in mental fatigue: Analysis of heart rate variability in Time-on-Task, recovery, and reactivity
TLDR
The present findings suggest that the parasympathetic branch of the autonomous nervous system functioning as a relaxation system tends to be activated under increasing mental fatigue, and many HRV indices also seem to change when individuals are engaged in a prolonged, less fatiguing activity. Expand
Mental Effort: Brain and Autonomic Correlates in Health and Disease
Mental effort is an embodied process for the short-term deployment of attentional, cognitive and affective resources. The engagement of mental effort involves whole brain shifts in the activation andExpand
Comparing real-life and laboratory-induced stress reactivity on cardio-respiratory parameters: Differentiation of a tonic and a phasic component
TLDR
Cardio-respiratory reactivity to a sequential protocol of different mental tasks of varying difficulties, some of them involving emotional material, and repeated the measures in a baseline and in a real-life stress situation showed a dual effect: first, a decreased RRI and RSA in rest values, and second, a decrease reactivity in RRI in response to mental tasks. Expand
Heart rate variability and cognitive processing: The autonomic response to task demands
TLDR
The results suggest that HRV is highly sensitive to overall demands of sustained attention over and above the influence of other cognitive processes suggested by previous literature. Expand

TLDR
Cardiac and metabolic changes during mental work were not a function of overall mental effort, but were specific to the effort due to memory load and to the individual differences among participants in their ability to perform the task. Expand
Glucose administration, heart rate and cognitive performance: effects of increasing mental effort
TLDR
It is suggested that supplemental glucose preferentially targets tasks with a relatively high cognitive load, which itself mobilises physiological reserves as part of a natural response to such tasks. Expand
Beyond Heart Rate in the Cardiac Psychophysiological Assessment of Mental Effort: The T-Wave Amplitude Component of the Electrocardiogram
TLDR
The paper concludes that, although controversial, TWA appears to provide a promising psychophysiological path for using cardiac performance measures to aid in the measurement and understanding of the psychological process of mental effort. Expand
Cognitive demand and blood glucose
TLDR
It is suggested that the amount of cognitive load associated with task performance is an index of its sensitivity to enhancement by glucose, which may be linked to increased neural energy expenditure during a period of intense cognitive processing. Expand
The Concept and Measurement of Mental Effort
This chapter will address the following questions: What is meant by mental effort? What is its role in human information processing? How can effort be measured? The chapter will consider the ways inExpand
Heart rate and oxygen consumption during active psychological challenge: the effects of level of difficulty.
TLDR
Heart rate and various metabolic and ventilatory indices were monitored while 24 young males engaged in two psychologically challenging tasks, mental arithmetic and Raven's matrices; in both tasks the easy condition was experienced as relatively unengaging and unarousing. Expand
Cardiovascular and endocrine responses to experimental stress: Effects of mental effort and controllability
TLDR
Investigating the unique and interactive effects of the controllability of a task and mental effort required by that task on cardiovascular and endocrine reactivity, when both were manipulated independently found having control seems to be most beneficial in high effort situations, at least with respect to sympathetic reactivity. Expand
Cognitive functioning is susceptible to the level of blood glucose
TLDR
This study investigated whether the performance of non-memory tasks was susceptible to the level of blood glucose, and suggested two physiological mechanisms, firstly, that an equilibrium develops between plasma and brain glucose, such that those with higher levels ofBlood glucose could be expected to haveHigher levels of brain glucose and whether there are individual differences in the efficiency with which glucose is taken from the blood. Expand
Information processing and cardiovascular control.
TLDR
It was shown that the power of the 0.10 Hz vasomotor oscillations was significantly affected by the processing demands of these tasks, and the evidence suggested a decreased baroreflex sensitivity (i.e. a decrease in gain) during mental loading. Expand
