Figure 1. Eye velocity during predictive pursuit at 18.7 and 9.9 degree/second.

Figure 1

Predictive pursuit task at 18.7°/sec: the three groups showed significant differences (F (2, 80) = 4.3, p < 0.05). Post hoc comparisons showed both BDP and SZ had slower eye velocity compared to HC (p < 0.05); SZ and BDP did not differ on predictive velocity (p > 0.98). A similar pattern emerged during the 9.9°/sec condition (F (2, 80) = 3.54, p < 0.04). Again, post hoc comparisons revealed volunteers with psychosis did not differ from each other (SZ vs. BDP, p > 0.98), while HC showed faster velocity than SZ at a trend level (p < 0.06)
