Table 1.

Performance between set size conditions in Experiment 2. Notes: The table shows the p values for each comparison. Error drops significantly as more faces are displayed to the participants. This result suggests that participants are integrating new information as it becomes available and not basing their response on one or two randomly selected faces.

Comparison of bootstrapped samples
	One versus two faces Displayed	Two versus four faces Displayed	Four versus 18 faces Displayed
Accuracy	p < 0.001	p < 0.001	p < 0.001
Precision	p = 0.008	p = 0.026	p = 0.006
