Figure 8.

Time-course of looking to the target (as determined by preference during the sample plus delay period) on trials in which the target changed color (Target-Change trials; blue line) and trials in which the target did not change (Target-No-Change trials; red line) during the time-course analysis window (50 ms before the change onset to the end of the trial) for the 4-month-old infants in Experiment 2. The lines represent the mean preference for the target item at each 16.67 ms time point before and after the test array appears (indicated by the vertical “Change Onset” line); the shading represents the 95% confidence interval for each time point. Clusters of time points in which infants’ preference was significantly greater than chance (.50; horizontal line bisecting the graph) is indicated by the colored lines at the bottom the plot; a blue line indicates the time points on Target-Change trials in which infants’ preferred the rotating item more than expected by chance, and the red line indicates the time points on Target-No-Change trials in which infants preferred the rotating item more than expected by chance. At no point did the 4-month-old infants’ preference differ in the two types of trials.
