The beginning:
Spatial Compatibility between Stimulated Eye and Response Location
Valle-Incla’n, F.,Sohn,F. and Redonda, M. (2008). Spatial Compatibility Between StimulateEye and Response Location. Psychophysiology, 45. DOI: 10.1111/j.1469- 8986.2007.00616.x
Response to monocular visual response is faster when the stimulus and reaction site are ipsilateral or compatibility trial than contraleral in an incompatibility trial. According to the Simon effect reaction times to a visual stimulus are faster and more accurate when the stimulus is on the same side as the response. Lu and Proctor (1995) suggest the existence of a visual code that is generated in the Simon effect (as cited by Umilta et al., 1999). Hypothesis: The size of the...
The end:
.....essing a keyboard depending on the color of the stimulus.
Findings from experimentConstant size of compatibility effect throughout the different reaction timesNo physiological signs of incorrect activation ConclusionInfluence of spatial code on response selection is tonicInfluence of monocular information is outside the visual cortexSpatial codes can be produced in the absence of attention movements
