Mean face-search accuracy for standard definition (SD) and high definition (HD) trials as a function of crowd size. As each point represents the average performance of 16,000 randomly sampled groups of participants (1000 groups per target identity), standard error bars (mean standard error = 0.003 for SD trials and mean standard error = 0.002 for HD trials) would lie within the marker point and are therefore not represented on the graph
