Second they suggested that subjectsвЂ™ choices give additional information about their preferences. First, they presumed that ratings are noisy measures of subjectsвЂ™ preferences. However a major statistical artifact was identified by Chen and Risen 11 who showed that spreading of alternatives could be observed in the absence of genuine preference change. Moreover, this encapsulated and automatic unconscious updating of values was associated with activity changes within the вЂvalue-networkвЂ™ including caudate nuclei and orbito-frontal cortices 9, 10. Similarly, spread was reported after a year-long delay period between choice and second rating 5, as well as in Capucin monkeys and in young infants 7, 8. A significant spreading of alternatives was observed in amnesic patients suffering from severe anterograde amnesia due to hippocampal lesion or dysfunction, as well as in normal controls under conditions of high cognitive load 4 or who forgot their choices for odorant items 6.

Since 2001 a cumulative series of empirical studies progressively introduced the notion that CIPC was independent from conscious episodic memory, and from the activity of hippocampal structures. This вЂspreading of alternativesвЂ™, or вЂspreadвЂ™, is the hallmark of this phenomenon, and has been considered as diagnostic of CIPC. Choice-induced preference change is defined by a tendency to increase ratings of chosen items, and to decrease those of rejected items. Finally, they perform a second rating on the same items. Second, they are engaged in a forced-choice task during which they have to choose between two closely rated items. First, subjects rank or rate items according to their desirability (e.g.: food items, car models, holiday destinations, etc.). However, in spite of a rich literature the relations prevailing between episodic memory and choice-induced preference change (CIPC) remain highly debated: is CIPC dependent 3 or independent 4, 5 from memory of past choices? In the present work we report a series of experiments using the FCP to solve this long-lasting issue.ДЄ typical FCP experiment is composed of three blocks.

Since then, several experimental paradigms have been designed to test this theory including the free-choice paradigm (FCP) 2. This link between current preferences and previous choices suggests a homeostatic function of this regulative process, aiming at preserving subjective coherence.ДЄccording to the cognitive dissonance theory initially framed in the 50вЂ‰s 1 by Festinger, our past choices influence our current preferences.

These results demonstrate the dependence of cognitive dissonance on conscious episodic memory.

Finally, we show that contrarily to a previous influential report flawed by a statistical artifact, this phenomenon is absent in amnesic patients for forgotten items. We used a combination of fMRI and intra-cranial electrophysiological recordings to reveal a modulation of left hippocampus activity, a hub of episodic memory retrieval, immediately before the occurrence of CIPC during item reevaluation. However the relations prevailing between episodic memory and choice-induced preference change (CIPC) remain highly debated: is this phenomenon dependent or independent from memory of past choices? We solve this theoretical debate by demonstrating that CIPC occurs exclusively for items which were correctly remembered as chosen or rejected during the choice stage. In the free-choice paradigm (FCP) after choosing between two similarly rated items, subjects reevaluate chosen items as more attractive and rejected items as less attractive.

The notion that past choices affect preferences is one of the most influential concepts of social psychology since its first report in the 50вЂ‰s, and its theorization within the cognitive dissonance framework.
