Creating emotional false recollections: Perceptual recombination and conceptual fluency mechanisms.

ABSTRACT: We investigated the impact of 2 hypothetical mechanisms of episodic memory reconstruction-perceptual recombination and conceptual fluency-on objectively measured recollection accuracy and false recollections of neutral and emotional stimuli. Participants encoded negative, neutral, and positive pictures depicting objects and scenes (i.e., target pictures), each accompanied with a descriptive verbal label (e.g., "boy crying at funeral," "wooden basket on floor," "four chimpanzees laughing together"). Next, they encoded fragmented pictures of some of the scenes they did and did not earlier see (perceptual misinformation), or they received multiple presentations of the corresponding verbal labels (conceptual misinformation). Recollection of target pictures was then tested, using labels as retrieval cues. We had three key findings in each of two experiments. First, as in our prior work, both perceptual and conceptual misinformation significantly increased false recollection judgments of nonstudied pictures, including high-confidence errors. These effects implicate perceptual recombination and conceptual fluency mechanisms. Second, these misinformation effects generalized across all emotional categories, implicating separable roles of these two mechanisms on emotional recollections. Finally, conceptual misinformation was less likely to influence negative than neutral recollection errors, providing new evidence that emotion can improve retrieval monitoring accuracy and reduce false memories based on conceptual fluency (i.e., an emotional distinctiveness heuristic).

Project description:This study explores the impact of the extensive use of an oral device since infancy (pacifier) on the acquisition of concrete, abstract, and emotional concepts. While recent evidence showed a negative relation between pacifier use and children's emotional competence (Niedenthal et al., 2012), the possible interaction between use of pacifier and processing of emotional and abstract language has not been investigated. According to recent theories, while all concepts are grounded in sensorimotor experience, abstract concepts activate linguistic and social information more than concrete ones. Specifically, the Words As Social Tools (WAT) proposal predicts that the simulation of their meaning leads to an activation of the mouth (Borghi and Binkofski, 2014; Borghi and Zarcone, 2016). Since the pacifier affects facial mimicry forcing mouth muscles into a static position, we hypothesize its possible interference on acquisition/consolidation of abstract emotional and abstract not-emotional concepts, which are mainly conveyed during social and linguistic interactions, than of concrete concepts. Fifty-nine first grade children, with a history of different frequency of pacifier use, provided oral definitions of the meaning of abstract not-emotional, abstract emotional, and concrete words. Main effect of concept type emerged, with higher accuracy in defining concrete and abstract emotional concepts with respect to abstract not-emotional concepts, independently from pacifier use. Accuracy in definitions was not influenced by the use of pacifier, but correspondence and hierarchical clustering analyses suggest that the use of pacifier differently modulates the conceptual relations elicited by abstract emotional and abstract not-emotional. While the majority of the children produced a similar pattern of conceptual relations, analyses on the few (6) children who overused the pacifier (for more than 3 years) showed that they tend to distinguish less clearly between concrete and abstract emotional concepts and between concrete and abstract not-emotional concepts than children who did not use it (5) or used it for short (17). As to the conceptual relations they produced, children who overused the pacifier tended to refer less to their experience and to social and emotional situations, use more exemplifications and functional relations, and less free associations.
