Results revealed a marginally significant main effect of target (B = 1.168, SE B = 0.679, z = −1.72, p = 0.86, 95% CI [−0.1641.214, 2.499]), such that White participants’ memory was significantly worse for the bystander than for the target.
As the interactions between social class and the Study 2 and Study 3 vectors failed to reach significance, we do not see definitive evidence of heterogeneity across studies—although the negative relationship between social class and incidental face memory was marginally more pronounced in Study 2 and marginally less pronounced in Study 3 relative to the IDA data set as a whole.
We predicted a significant negative association between social-class and incidental face memory (i.e., memory for the bystander; orange line in Figure 5 ) and while this effect is in the predicted direction, it did not reach conventional levels of significance (B = −0.041, SE B = 0.032, 95% CI [−0.104, 0.021]).
While we found that social class significantly moderates the association between target role and eyewitness accuracy in Study 3, the negative association between a person’s social class and incidental face memory did not reach statistical significance.
