Figure 5.

Human subjects' performance is better on multisensory trials even when the synchronous and independent conditions are presented in alternating blocks. a, Scatter plot for all subjects comparing the observed thresholds on the multisensory condition with the predicted thresholds. Data from the synchronous (circles) and independent (triangles) conditions are shown together. Error bars indicate 95% CIs. b, Subjects perform better on bonus trials compared with the matched trials and slightly worse on neutral trials. Conventions are the same as in Figure 4c. n = 1390 (matched condition), 2591 (bonus condition), and 2464 (neutral condition). Prop, Proportion.
