Appendix B
Recollection and familiarity analyses.
Separate contributions of recollection and familiarity to recognition were evaluated using the independence remember–know (IRK) procedure for each experiment (Yonelinas, 2002; Yonelinas & Jacoby, 1995). The IRK procedure estimates the contribution of recollection by the proportion of trials in which participants make “remember” (R) responses, and estimates the contribution of familiarity by the proportion of trials in which participants make “know” (K) responses, given that a remember response is not made (1-R). These estimates of recollection and familiarity were computed separately for hits and false alarms, and statistical analyses were conducted on the hit minus false alarm difference scores, which are displayed in Tables 6 and 7.
Table 6 Estimates for recollection and familiarity based on the independence remember–know procedure for Experiment 1
Table 7 Estimates of recollection and familiarity for Experiments 2A and 2B
Experiment 1
To evaluate differences in recollection and familiarity, the hits minus false alarm difference scores were submitted to two separate two-tailed paired sample t tests, comparing across trial types. The analysis on the estimates of recollection revealed a significant effect of trial type, t(47) = 4.384, p < 0.001, d = 0.633, with higher estimates for incongruent (0.305) than congruent trials (0.240). The analysis on the estimates of familiarity revealed a marginal effect of trial type, t(47) = 1.761, p = 0.085, d = 0.254, with a numerical trend toward higher estimates for incongruent (0.321) than congruent trials (0.286) (Table 8).

Experiment 2
To evaluate differences in recollection and familiarity, the hits minus false alarm difference scores were submitted to two separate mixed-factor ANOVAs, with list type as a between-subjects factor and trial type as a within-subject factor.
Experiment 2A
The analysis on the estimates of recollection revealed a significant main effect of trial type, F(1, 46) = 11.329, p = 0.001, \(\eta _{{\text{p}}}^{2}\) = 0.198, reflecting higher recollection estimates for targets on incongruent (0.323) than congruent (0.278) trials. Neither the main effect of list type nor its interaction with trial type reached significance. The analysis on the familiarity estimates revealed a main effect of trial type, F(1, 46) = 4.44, p = 0.041, \(\eta _{{\text{p}}}^{2}\) = 0.088, reflecting higher familiarity estimates for targets on incongruent (0.290) than congruent (0.252) trials. A main effect of list type was also observed, F(1, 46) = 6.411, p = 0.015, \(\eta _{{\text{p}}}^{2}\) = 0.122, indicating familiarity estimates were higher in the mixed (0.318) than blocked (0.223) condition. The interaction between trial type and list type was not significant.
Experiment 2B
The analysis on recollection estimates revealed an effect of trial type that approached significance, F(1, 46) = 3.32, p = 0.075, \(\eta _{{\text{p}}}^{2}\) = 0.067, with numerically higher estimates for incongruent (0.380) than congruent trials (0.344). No other analyses on the recollection or familiarity estimates yielded significant effects, all p’s > 0.10.
Experiment 3
To evaluate differences in recollection and familiarity, the hits minus false alarm difference scores were submitted to two separate two-tailed paired sample t tests, comparing across trial types.
Experiment 3A
The two analyses revealed higher estimates for incongruent than for single word trials both for recollection, t(47) = 3.913, p < 0.001, d = 0.565 (0.348 vs. 0.274), and familiarity, t(47) = 3.058, p = 0.004, d = 0.441 (0.288 vs. 0.217).
Experiment 3B
The analysis on recollection estimates was not significant, t(47) < 1. The analysis on familiarity estimates revealed an effect of trial type, t(47) = 3.617, p < 0.001, d = 0.522, with higher familiarity estimates for congruent (0.303) than for single word trials (0.241).
