In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
Health effects on intelligence have been described as being among the most important factors in the origins of human group differences in IQ test scores and other measures of cognitive ability. [1] Several factors can lead to significant cognitive impairment, particularly if they occur during pregnancy and childhood when the brain is growing ...
Fatigue that is experienced by participants of these kinds of studies is induced by attention-intensive tasks, [3] and the observed effects of such fatigue are correlated with decline in inhibitory control. Signs of Directed Attention Fatigue include temporarily feeling unusually distractible, impatient, forgetful, or cranky when there is no ...
The PASS theory provides the theoretical framework for a measurement instrument called the Das-Naglieri Cognitive Assessment System (CAS), published in 1997. [6] This test, now in a Second Edition (CAS2; 2014, Naglieri, Das & Gold-stein) is designed to provide an assessment of intellectual functioning redefined as four brain-based cognitive processes (Planning, Attention, Simultaneous and ...
The same study also found that the correlation between brain size and Intelligence increased with age, with children showing smaller correlations. [18] It has been suggested that the link between larger brain volumes and higher intelligence is related to variation in specific brain regions: a whole-brain measure would under-estimate these links ...
The Triarchic Theory of Intelligence or Three Forms of Intelligence, [1] formulated by psychologist Robert Sternberg, aims to go against the psychometric approach to intelligence and take a more cognitive approach, which leaves it to the category of the cognitive-contextual theories. [2] The three meta components are also called triarchic ...
For example, it would allow the testing of how fatigue or a new technology would affect a driver or a pilot in their specific environment, without the possibility of injury. Being able to evaluate the effects of some new workplace technology in virtual reality, before real life implementation, could save money and lives.
The free energy principle is a theoretical framework suggesting that the brain reduces surprise or uncertainty by making predictions based on internal models and updating them using sensory input. It highlights the brain's objective of aligning its internal model and the external world to enhance prediction accuracy.
