Table 1.
A’ values (calculated using hit rate and false alarm rates) by object type for objects drawn from temporal-plus-semantic pairs (T+S) and temporal-only pairs (T-only) in bold, followed by standard error of the mean in italics, and B”D in parentheses. Consistent with the pattern of results found with hit rates, analyses of A’ in Experiments 2 and 3 show significant recognition-induced forgetting for temporal-plus-semantic pairs (E2: t(25)=2.947, p=.007, JZS=6.50; E3: t(43)=5.035, p<.001, JZS=2,166.21) but not temporal-only pairs (E2: t(25)=.584, p=.564, JZS=4.13; E3: t(43)=1.045, p=.302, JZS=3.68) and Experiment 4 shows no significant recognition-induced forgetting, t(25)=.605, p=.550, JZS=4.08. Closely approximating the pattern found with hit rates in Experiment 1, analysis of A’ for temporal-plus-semantic objects in Experiment 1 approaches significant recognition-induced forgetting, t(25)=1.964, p=.061, JZS=1.08, but temporal-only paired objects do not show significant recognition-induced forgetting, t(25)=.493, p=.627, JZS=4.32. The pattern of results obtained using A’ follows the pattern of hit rates across all four experiments in that memory for related objects was lower than memory for baseline objects for temporal-plus-semantic objects in Experiments 1–3 while memory for related objects was higher or equivalent for temporal-only objects. There were no significant differences between for baseline B”D and related B”D in any of relatedness condition in Experiments 1 and 2. There was a reliable difference between baseline B”D and related B”D in Experiment 3 in the T+S condition, t(43)=4.70, p<.001, JZS=791 in favor of the alternative hypothesis, but not the T-only condition. We compared baseline and related because it is the comparison between these two object types that are measured in the determination of recognition-induced forgetting.
