Area of Science:

  • Cognitive Neuroscience
  • Psychology

Background:

  • Mental energy, though not well-defined, is of significant public interest.
  • It can be conceptualized as a mood or the capacity/willingness for cognitive tasks.

Purpose of the Study:

  • To review the concept of mental energy.
  • To discuss methods for assessing mental energy, including cognitive tests.
  • To examine factors influencing mental energy.

Main Methods:

  • Review of cognitive performance tests, mood questionnaires, electrophysiological techniques, brain scanning, and ambulatory monitoring.
  • Analysis of studies on factors affecting mental energy (e.g., drugs, sleep deprivation, disease).
  • Identification of optimal cognitive tests for mental energy assessment.

Main Results:

  • Cognitive tests measuring vigilance, sustained attention, and choice reaction time are optimal.
  • Recommended tests include Psychomotor Vigilance Task and Wilkinson reaction time tests.
  • These tests are sensitive to factors that modulate mental energy.

Conclusions:

  • Vigilance and reaction time tests are effective tools for assessing mental energy.
  • Standardized assessment methods are crucial for reliable mental energy research.
  • Further research should consider critical factors in study design and conduct.
