Figure 4

Upper panel: Schematic diagram of design examining maintenance of relational information across trials. Trial A immediately preceded Trial B. In the hiHom condition, the stimuli in Trial A were homogeneous (blue dashed line is short), while in Trial B, the two stimuli were different from one another (blue dashed line is longer). The horizontal axis represents the stimulus space, items closer to each other are more similar. If relational information were maintained from trial to trial, more false alarms (on Trial B) would be expected for the loHom condition, as the false alarm rate on Trial A is greater in that condition. Note that Trial B is the same in each case. p indicates the probe frequency, s1 and s2 indicate the frequencies of the first and second study stimuli. Lower panel: Identical trials following trials of high inter-item homogeneity (hiHom) or low inter-item homogeneity (loHom) showed no difference in proportion correct. Symbol conventions as in Figure 3. This form of relational information is not carried over from trial to trial.
