Methylphenidate effect on attentional and cognitive behavior in six- through twelve-year-old males. | Attentional and cognitive behavior was studied in 84 learning disabled boys aged 6 through 12 yr., before and during treatment with methylphenidate (Ritalin). The WISC Digit Span and Coding, identified as measures of primarily attentional behavior, showed significant improvement with methylphenidate treatment. Block De... | 604,892 | [

Hemispheric asymmetry in reaction time to color stimuli. | The simple detection of colored stimuli in the right, center, and left visual fields was examined. 10 male subjects were used in a reaction time paradigm with color (red, green, or blue), field, and hand as independent variables. A significantly faster RT to stimuli presented in the left visual field was observed, and ... | 604,893 | [
