Figure 6.

The time-courses of the average change in oxy-, deoxy-, and total-Hb concentrations during the same-face and different-face condition under the multiple viewpoint presentation in 5- to 6-month-old infants and 7- to 8-month-old infants in Experiment 2. In both age groups, the two graphs in the top part indicate the data for oxy-Hb, the two graphs in the middle part for deoxy-Hb, and the two graphs in the bottom part for total-Hb. The data for the left temporal area are shown in the left column and those for the right temporal area are shown in the right column. In each graph, the black line represents the mean Z-score of the different-face condition and the gray line represents that of the same-face condition.
