Decision time and movement time as a function of response complexity in retarded persons.

摘要: The decision time (reaction [RT]) and movement of retarded persons as a function the amplitude precision discrete in both simple choice RT paradigms was examined. results showed that for considerably longer more variable than nonretarded persons. Movement difficulty only elevated with populations paradigm, regression coefficient subjects greater group. Retarded subjects' significantly slower subjects. populations, defined by Fitts's (1954) law. slope movement-time coefficients higher did not change across 5 days practice. These findings suggest information-processing differences motor skills between can be attributed to response parameters. Language: en
