| Abstract: | The length of time that infants fixated patterns of varying complexity was studied in a series of experiments using stimuli made up of black lines on a white ground. In Exp. I, the effects of the number of horizontal lines and the regularity of their arrangement was examined. In Exp. II, the arrangement of the lines was varied while keeping the number of resulting white rectangular spaces constant. Experiment III served as a control for the introduction of vertical lines in the patterns of Exp. II. In Exp. IV, the number of white rectangular spaces was varied while keeping the number of lines constant. The results of these studies showed that infants looked longer at patterns with a greater number of lines, regardless of whether they were arranged regularly or irregularly, and the number of white rectangular spaces created by the lines was a particularly important determinant of visual attention. |
