1967
Journal of Experimental Psychology
In 2 discrimination reaction-time experiments, adult human Ss responded faster to horizontal and vertical stimuli (lines or rectangles) than to stimuli tilted 45° right and left. When S viewed the stimuli with his head tilted 45°, so that physical and retinal orientation were in opposition, it was on the physical rather than the retinal horizontals and verticals that performance was superior. In another experiment head position was changed 45° after a period of learning. Ss required to give the
