Discrimination of speed in 5-year-olds and adults: Are children up to speed?
We compared thresholds for discriminating changes in speed by 5-year-olds and adults for two reference speeds: 1.5 and 6 degrees s(-1). Both adults and 5-year-olds were more sensitive to changes from the faster than from the slower reference speed. Five-year-olds were less sensitive than adults at both reference speeds but significantly more immature at the slower (1.5 degrees s(-1)) than at th...
متن کاملgeneral intelligence or speed of information processing?
at the beginning of the present century, problems such as education of mentally retarded children, classification and placement of job applicants in industrial and military organizations, and students selection, gave impetus to the development of intelligence tests and the formulation of theories of intelligence. for many years factorial theories of intelligence dominated the field, but piaget&...
متن کاملLow- and high-level controlled processing in executive motor control tasks in 5-6-year-old children at risk of ADHD.
BACKGROUND The scant research on the characteristics of Attention-Deficit/Hyperactivity Disorder (ADHD) in kindergarten years curtails progress on early assessment of ADHD. METHOD By screening a general population sample of 1317 five- to six-year-old children, four groups of children were selected. The performance of 30 children later diagnosed with ADHD was compared with 74 children later di...
متن کاملEffect of Object Location on Selecting the Limb in Unilateral Reaching in 5- to 6-Year-Old Children
Purpose: The traditional view regards limb selection in reaching a hemispheric specialization and an permanent biological phenomenon. However, recent studies have questioned this idea. Instead, they suggest that the task conditions is also an effective factor. The present study includes two experiments in right and left handed children examining the effect of object location as a task condition...
متن کاملSpeed of information processing
Speed of information processing in the subacute stage after stroke was studied in 88 first-ever, unilateral ischemic stroke patients. The patient group included 42 right and 46 left hemisphere patients. Seventy-one control subjects were also examined. Four reaction time tasks with different levels of complexity were used: two visuomotor, and two semantic categorisation tasks. The results showed...
