ABILITY OF OBSERVERS TO ADJUST LINEAR STIMULI TO A HORIZONTAL ORIENTATION,

Abstract

Two laboratory experiments were conducted to assess human performance in adjusting linear stimuli to a horizontal position. In the first experiment, solid lines of various lengths were used as stimuli and, in the second experiment, the stimuli were pairs of 'dots' separated by various intervals. In both studies the subject's task was to adjust the stimulus to a horizontal position. The experiments were conducted in a completely darkened room with the stimuli illuminated by an ultraviolet light. (Author)
