Mean Split-Half and Overall Continuous Performance Task Measures (n =12)
| Hits (range; SD) | False Alarms (range; SD) | Accuracy (range; SD) | Sensitivity (range; SD) | Response Bias* (range; SD) | |
|---|---|---|---|---|---|
| 1st half | 0.92 (0.77–1.0; 0.09) | 0.22 (0–0.70; 0.19) | 0.71 (0.24–1.0; 0.22) | 0.91 (0.75–1.0; 0.08) | −0.42 (−1–0.55; 0.53) |
| 2nd half | 0.89 (0.59–1.0; 0.11) | 0.32 (0–0.95; 0.26) | 0.58 (−0.06–1; 0.30) | 0.86 (0.44–1.0; 0.14) | −0.40 (−1–0.29; 0.41) |
| Overall | 0.91 (0.69–1.0; 0.09) | 0.27 (0–0.83; 0.22) | 0.64 (0.14–1.0; 0.24) | 0.89 (0.64–1.0; 0.10) | −0.40 (−1–0.29; 0.36) |
calculations exclude 1 subject who did not have false alarms for response bias calculation
