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 further the left visual field-left hand combination was the fastest of all the combinations of visual-field x hand.

The familial and societal involvement in the process of alienation is discussed and some issues relating particularly to the institutionalized patient are identified.
