Hemispheric asymmetry in reaction time to color stimuli. 1977

M Pirot, and T W Pulton, and L W Sutker

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. A significant interaction of color x field suggested that red may be processed on a higher order level even in a simple detection task.

UI MeSH Term Description Entries
D007839 Functional Laterality Behavioral manifestations of cerebral dominance in which there is preferential use and superior functioning of either the left or the right side, as in the preferred use of the right hand or right foot. Ambidexterity,Behavioral Laterality,Handedness,Laterality of Motor Control,Mirror Writing,Laterality, Behavioral,Laterality, Functional,Mirror Writings,Motor Control Laterality,Writing, Mirror,Writings, Mirror
D008297 Male Males
D011930 Reaction Time The time from the onset of a stimulus until a response is observed. Response Latency,Response Speed,Response Time,Latency, Response,Reaction Times,Response Latencies,Response Times,Speed, Response,Speeds, Response
D003118 Color Perception Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary. Color Perceptions,Perception, Color,Perceptions, Color
D004192 Discrimination, Psychological Differential response to different stimuli. Discrimination, Psychology,Psychological Discrimination
D004292 Dominance, Cerebral Dominance of one cerebral hemisphere over the other in cerebral functions. Cerebral Dominance,Hemispheric Specialization,Dominances, Cerebral,Specialization, Hemispheric
