Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function.
Studies show that intelligence is positively correlated with total cerebral volume. [1] While it is true that the number of neurons in the brain actually decreases throughout development, as neural connections grow and the pathways become more efficient, the supporting structures in the brain increase.
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 ...
Psi-theory, developed by Dietrich Dörner at the University of Bamberg, is a systemic psychological theory covering human action regulation, intention selection and emotion. [ 1 ] [ 2 ] It models the human mind as an information processing agent, controlled by a set of basic physiological, social and cognitive drives.
[1] [2] [3] According to Cattell's psychometrically-based theory, general intelligence (g) is subdivided into g f and g c. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem-solving, and learning. [4]
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 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 ...
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 ...
