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.
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 ...
The motor theory of speech perception would predict that speech motor abilities in infants predict their speech perception abilities, but in actuality it is the other way around. [33] It would also predict that defects in speech production would impair speech perception, but they do not. [ 34 ]
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.
Michael A. Persinger (June 26, 1945 – August 14, 2018) was an American-Canadian professor of psychology at Laurentian University, a position he had held from 1971 until his death in 2018. [1]
The challenge point framework, created by Mark A. Guadagnoli and Timothy D. Lee (2004), provides a theoretical basis to conceptualize the effects of various practice conditions in motor learning. This framework relates practice variables to the skill level of the individual, task difficulty, and information theory concepts.
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.
