The power of extraversion? Reduced false memories for positive events

Emotion in action: A study on the enactment effect on emotional action sentences

While abundant literature suggests that both performing congruent actions and emotional stimuli can enhance memory, their combined impact on memory for action phrases remains underexplored. This study investigated the effects of enactment with emotionally charged stimuli on memory performance. Sixty participants encoded action sentences with negative, neutral, or positive emotional connotations using either enactment or verbal-reading methods. Memory performance was assessed through immediate free recall tasks and a delayed yes-no recognition task. Results demonstrated a significant memory advantage for action-enacted sentences compared to verbal reading in recall and recognition tasks. Moreover, recall accuracy was higher for negative action sentences, while recognition performance was enhanced for negative and positive sentences. No interaction was found between encoding type and emotional connotation in memory tasks. Our findings revealed that both enactment and valence independently enhance memory performance, extending the benefits of enactment to emotional stimuli. Furthermore, our results highlight the differential effects of valence on free recall and recognition tasks, suggesting task-specific processes related to memory for negative and positive stimuli.

Psychopathic personality traits are linked to reduced false memories for negative events

Individuals scoring high on psychopathic personality traits process emotional material to a different extent than individuals with few psychopathic traits. Evidence exists that these individuals have impaired emotional memory. The question arises whether this emotional memory impairment has ramifications for the production of emotional false memories. In the present study, we investigated the production of false and true memories for emotional events in a community sample (N = 120) of individuals varying in psychopathic traits (evaluated with the Psychopathic Personality Inventory-Revised [PPI-R] questionnaire). The fearless dominance (FD) component of psychopathy interacted with the emotional impact of to-be-remembered events in the production of false memories, showing fewer negative false memories with increasing levels of FD. At the subjective level, negative false memories were not perceived as vivid memory experiences in high FD individuals. Concerning true memories, higher scores in cold-heartedness were related to fewer true memories for neutral and negative (but not positive) events. These results show that individuals with high psychopathy traits - in particular, FD - do not have a general emotional memory impairment but they process negative material in a different way than individuals with low psychopathic traits and thus are less susceptible to producing false memories for negative events.

Working Memory Beats Age: Evidence of the Influence of Working Memory on the Production of Children's Emotional False Memories

Emotional valence and working memory ability (WM) affect false memories’ production in adults. Whereas a number of studies have investigated the role of emotional valence in children’s tendency to produce spontaneous false memories, individual differences in WM have not been previously included. In the current article, we were interested in investigating whether emotion and WM would interact in influencing the propensity to incur inferential false memories for scripted events. Ninety-eight typically developing children (first-, third-, and eighth- graders) were administered the Emotional false memory paradigm – allowing to study false memories for negative, positive, and neutral events – and a WM task. Results showed that regardless of age, valence influenced false memories’ production, such that positive events protected against incurring distortions. Furthermore, WM interacted with valence, such that children with higher WM abilities produced fewer false memories for negative events. Concerning confidence judgments, only the youngest group of children claimed to be overconfident when committing false memories for negative and neutral events. Results are discussed in terms of the role of individual differences in higher cognitive abilities interacting with the emotional content of to-be-remembered events.

False memory for pictorial scripted material: the role of distinctiveness and negative emotion

Emotional content has complex effects on false memory. Under certain circumstances, emotional material may reduce the likelihood of false memory, a phenomenon that some consider related to it being more distinctive than neutral stimuli. In the present study we tested inferential false memory related to emotionally neutral or negative, and distinctive (but not emotionally charged) scripted material. Remember/familiar judgements were required for recognised stimuli. Data were analysed using mixed-effects multinomial regressions and a Bayesian inferential approach. Results obtained with 82 adult participants showed that, compared with neutral material: distinctive material reduced their false memory associated with "remember" and "familiar" judgements, virtually to the same extent; negatively-charged material reduced false memory associated with "remember" judgements but it had no effect on false memory associated with "familiar" judgements. In short, negatively-charged and distinctive material seems to affect false memory in different ways: the latter affects both recollection and familiarity, the former only recollection.
