Table 2 Results from three separate 2 (Face Race) × 2 (JOL type, Immediate vs Delayed) ANOVAs on d’ values, false alarm rates (FAR), and hit rates (HR)

From: Postdictive confidence (but not predictive confidence) predicts eyewitness memory accuracy

  1. df degrees of freedom per test
  2. Effect sizes reported are partial-eta squared. These statistics indicate that on all three measures of recognition memory accuracy, the effect size for the Cross-Race Effect was greater in Experiment 2 than Experiment 1
  3. ap < 0.05, bp < 0.01, cp < 0.001
