Figure 4: Amnesic patients with hippocampal dysfunction show CIPC exclusively for remembered items.
From: Cognitive dissonance resolution depends on episodic memory
The triple interaction between group (matched controls/aMCI), condition (RCR/RRC) and memory (remembered/forgotten) was not significant. Post-hoc analysis confirmed that while patients forgot more, they showed the very same pattern of behavioral results: CIPC was found significant exclusively for remembered items. We could also replicate the regression to the mean statistical artifact (RCR all items versus zero on the red leftmost bar of patients) present in the Lieberman et al.4 study. No CIPC was found in the absence of explicit memory of previous choices.
