Both models combine the optimum principles and the equilibrium-point hypothesis (motor commands λ are taken as coordinates of the internal space). The input motor command λ is found by minimizing the length of the path traveled in the internal space, either under the acoustical constraint (the first model), or under the both acoustical and ...
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 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 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.
The existence of motor equivalence, i.e., the ability to perform the same action in multiple ways for instance using different muscles or the same muscles under different conditions. This suggests that a general code specifying the final output exists which is translated into specific muscle action sequences
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 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.
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.
