| Correct hit % (adjusted for Age and Race) | 2.29 (=.003) | 30.32 (< .001) | 3.36 (<.001) |
| d’ ANOVA | 338.02 (< .001) | 33.37 (< .001) | 2.55 (=.005) |
| d’ ANCOVA (Adjusted for Age) | 16.10 (< .001) | 35.12 (< .001) | 2.86 (=.002) |
| d’ (Adjusted for Age and Race) | 4.71 (<.001) | 32.75 (< .001) | 2.24 (=.012) |
Note. Results of three-way ANOVAs and ANCOVAs with two within-subjects variables (5 task conditions, 2 trials per condition) and one between-subjects variable (3 groups). Interactions with Time are not shown as they were not statistically significant.
d’ is a measure of efficiency that takes into account both hit and false alarm rate.
