Abstract |
The experiment dealt with the perception of movement of two lights exposed in a darkroom. Both lights were moved, in the same or in opposite directions, or only one light was moved, and the subject's accuracy in reporting the nature of the movement was determined. Relative intensity of the two lights was found to be an important factor; the less intense light was the more mobile. Fixation and position were found to make a difference, but absolute intensity, practice, and knowledge had but slight influence. (PsycINFO Database Record (c) 2012 APA, all rights reserved) |
