Procedure and stimuli for Experiments 1 and 2.
(a) Schematic illustration of the procedure for Experiments 1 and 2. The procedure of Session 1 is the same for Experiments 1 and 2 (with the exception of the number of trials). Participants …

Experiment 1 error in item and gist memory at Session 1 (a) and at Session 2 (b).
* indicates p < 0.05, **** indicates p < 0.0001, and ns indicates p > 0.05 by t-tests between groups and ANOVA (top left). Red dashed lines indicate chance performance for item (defined as the …

Figure 2—figure supplement 2
Experiment 1 error change between Session 1 and 2 in gist memory, estimated gist, and simulated estimated gist based on a simple item-only simulation.
Item-only simulation assumed that the magnitude of error for each item memory would remain the same but the direction of error would not be systematically influenced by the gist. [We generated 1000 …

Bias measurement and results at each session.
(a) Bias measurement. The bias for each recalled location is (red - yellow) / green. The blue square is an example of a recalled item that is biased away from the reported center and the blue …

Change in error by delay and memory type (the band indicates the median, the box indicates the first and third quartiles, the whiskers indicate ± 1.5 × interquartile range, and the solid points indicate outliers).
Greater values indicate an increase in error from Session 1 after delay. **** p <0.0001 by Wilcoxon signed rank tests. Dots and lines indicate participants. Figure 4—figure supplement 1 shows the …
