Visual Attention. (A-D) Each individual is represented by a circle. The group mean is represented by the solid line, and the standard error is represented by the dotted lines. (A). Groups did not differ on the proportion of the play session that each child spent looking at toys. (B) Groups did not differ on the number of unique toys (in the set of 24) that each child looked at during play. (C) Groups did not differ on the number of looks to toys that they generated per minute, (D) nor on the median duration of looks to toys. (E-F) Each individual is represented by a thin line. The bold lines represent the group means, and the shaded region represents the standard error. (E) The x-axis is the session time in seconds, and the y-axis is the cumulative unique number of toys viewed, such that each participant’s line increases by 1 each time they view a toy that they have not yet viewed. There were no differences between groups in the rate of looking at previously unviewed toys. (F). The x-axis is the rank ordered toy, such that for each child their most looked at toy is ranked 1 and their least looked at toy is ranked as 24. The y-axis is the proportion of the session spent looking at that toy. There were no differences between groups in the amount of the session spent looking at any of the toys, in rank order.
