A person's motor system (that controls movement of the body) is activated when (1) they observe manipulable objects, (2) process action verbs, and (3) observe another individual's movements. [ 2 ] Embodied semantics is one of two theories concerning the location and processing of sensory motors inputs within the human brain.
The book traces the origins of the idea of individual differences in general mental ability to 19th century researchers Herbert Spencer and Francis Galton. Charles Spearman is credited for inventing factor analysis in the early 20th century, which enabled statistical testing of the hypothesis that general mental ability is required in all mental efforts.
The subsequent formulation was that the magnitude of the black-white difference on tests of cognitive ability is entirely or mainly a function of the extent to which a test measures general mental ability, or g. [2] Spearman's hypothesis has been criticized on methodological and empirical grounds. It has also been used to support scientific racism.
The g factor [a] is a construct developed in psychometric investigations of cognitive abilities and human intelligence.It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks.
Bicameral mentality is a hypothesis introduced by Julian Jaynes who argued human ancestors as late as the ancient Greeks did not consider emotions and desires as stemming from their own minds but as the consequences of actions of gods external to themselves.
Though this theory represented an important leap forward in motor learning research, [1] one weakness in Adams’ closed-loop theory was the requirement of 1-to-1 mapping between stored states (motor programs) and movements to be made. This presented an issue related to the storage capacity of the central nervous system; a vast array of ...
Threshold hypothesis Ellis Paul Torrance (October 8, 1915 [ 2 ] – July 12, 2003) was an American psychologist best known for his research in creativity . After completing his undergraduate degree at Mercer University , Torrance acquired a Master's degree at the University of Minnesota and then a doctorate from the University of Michigan .
Research that has implemented motor learning and rehabilitation practice has been used within the stroke population and includes arm ability training, constraint-induced movement therapy, electromyograph-triggered neuromuscular stimulation, interactive robot therapy and virtual reality-based rehabilitation. A recent study ischemic conditioning ...
