2.4. Predicting the effects of cross-examination-style questioning Next, we examined several possible predictors of participants’cross-examination performance. First, we examined whether response accuracy in the first interview was related to the probability that that response would be changed under cross-examination.For each participant, we calculated the proportion of responses changed, as a function of initial accuracy. Proportions could not be calculated for 10 children, 8 adolescents, and 9 adults because at the first interview they responded correctly on all four of the questions on which they were later cross-examined, and for one child because she responded incorrectly on all four questions. Separate related-samples Wilcox on signed rank tests were conducted for each age group. Adults changed initially incorrect responses more often than initially correct responses (median proportion of responses changed = 1.0 and .50, respectively; z = 2.10, N – Ties = 27, p = .04,d = 0.54). In contrast, incorrect responses made by younger partic-ipants were no more likely to be changed than correct responses(ps = .25 and .44)
