Commitment in romantic relationships as a function of partners’ encoding of important couple-related memories

The purpose of the present study was to investigate how significant couple-related events are encoded in the episodic memory of each partner of a romantic relationship and how they relate to each of these partners’ level of commitment in an independent and additive fashion. Each partner of a couple reported a significant couple-related memory and rated their level of need satisfaction experienced during the event of the memory. In addition, each partner was shown his/her partner’s memory and also rated their own level of need satisfaction for this event. Results showed that partners need satisfaction ratings of their own memory positively predicted their own commitment to the relationship directly (for women) as well as through their need satisfaction generally experienced in the relationship (for men). In addition, men’s need satisfaction ratings of their own memory were associated with women’s commitment while controlling for women’s need satisfaction ratings of men’s memory, but no such cross-partner effects were found for women. Overall, the findings shed light on an initial understanding of how a person’s own memory of an event can impact another person’s attitudes even when taking into account this other person’s memory encoding of that same event.     

Accessibility and characteristics of memories of the future

Recent research suggests that some imagined future events are encoded in memory, leading to the formation of “memories of the future”. However, questions remain regarding the exact components of future event simulations that are encoded and the factors that determine their accessibility. To address these questions, the present study investigated memory for previously imagined future events using both free and cued recall tasks. The results showed that most future event simulations were successfully encoded and remained available in memory after a one week delay, but only some of them were readily accessible, whereas others could only be accessed when relevant cues were provided. Persons and locations were particularly well remembered, suggesting that these components are central to the simulation and memorisation of future events. We also found that memory for future event simulations was related to the clarity and familiarity of represented persons, the subjective feelings of pre-experience and mental time travel, the importance of imagined events to personal goals, and their emotional intensity during the initial simulation phase. Taken together, these findings expand our understanding of the formation, accessibility, and characteristics of memories of the future.     

Does goal relevant episodic future thinking amplify the effect on delay discounting?

Delay discounting (DD) is the preference for smaller immediate rewards over larger delayed rewards. Research shows episodic future thinking (EFT), or mentally simulating future experiences, reframes the choice between small immediate and larger delayed rewards, and can reduce DD. Only general EFT has been studied, whereby people reframe decisions in terms of non-goal related future events. Since future thinking is often goal-oriented and leads to greater activation of brain regions involved in prospection, goal-oriented EFT may be associated with greater reductions in DD than general goal-unrelated EFT. The present study (n = 104, M_age = 22.25, SD = 3.42; 50% Female) used a between-subjects 2 × 2 factorial design with type of episodic thinking (Goal, General) and temporal perspective (Episodic future versus recent thinking; EFT vs ERT) as between factors. Results showed a significant reduction in DD for EFT groups (p < 0.001, Cohen’s d effect size = 0.89), and goal-EFT was more effective than general-EFT on reducing DD (p = 0.03, d = 0.64).     

Emotional intensity in episodic autobiographical memory and counterfactual thinking

Episodic counterfactual thoughts—imagined alternative ways in which personal past events might have occurred—are frequently accompanied by intense emotions. Here, participants recollected positive and negative autobiographical memories and then generated better and worse episodic counterfactual events from those memories. Our results suggest that the projected emotional intensity during the simulated remembered/imagined event is significantly higher than but typically positively related to the emotional intensity while remembering/imagining the event. Furthermore, repeatedly simulating counterfactual events heightened the emotional intensity felt while simulating the counterfactual event. Finally, for both the emotional intensity accompanying the experience of remembering/imagining and the projected emotional intensity during the simulated remembered/imagined event, the emotional intensity of negative memories was greater than the emotional intensity of upward counterfactuals generated from them but lower than the emotional intensity of downward counterfactuals generated from them. These findings are discussed in relation to clinical work and functional theories of counterfactual thinking.     

Exploring the experience of episodic past,future, and counterfactual thinking in younger and older adults: A study of a Colombian sample

Although extant evidence suggests that many neural and cognitive mechanisms underlying episodic past, future, and counterfactual thinking overlap, recent results have uncovered differences among these three processes. However, the extent to which there may be age-related differences in the phenomenological characteristics associated with episodic past, future and counterfactual thinking remains unclear. This study used adapted versions of the Memory Characteristics Questionnaire and the Autobiographical Interview in younger and older adults to investigate the subjective experience of episodic past, future and counterfactual thinking. The results suggest that, across all conditions, younger adults generated more internal details than older adults. However, older adults generated more external details for episodic future and counterfactual thinking than younger adults. Additionally, younger and older adults generated more internal details, and gave higher sensory and contextual ratings, for memories rather than future and counterfactual thoughts. Methodological and theoretical consequences for extant theories of mental simulation are discussed.     

Phonological abstraction in processing lexical-tone variation: evidence from a learning paradigm

There is a growing consensus that the mental lexicon contains both abstract and word-specific acoustic information. To investigate their relative importance for word recognition, we tested to what extent perceptual learning is word specific or generalizable to other words. In an exposure phase, participants were divided into two groups; each group was semantically biased to interpret an ambiguous Mandarin tone contour as either tone1 or tone2. In a subsequent test phase, the perception of ambiguous contours was dependent on the exposure phase: Participants who heard ambiguous contours as tone1 during exposure were more likely to perceive ambiguous contours as tone1 than participants who heard ambiguous contours as tone2 during exposure. This learning effect was only slightly larger for previously encountered than for not previously encountered words. The results speak for an architecture with prelexical analysis of phonological categories to achieve both lexical access and episodic storage of exemplars.     

The change probability effect: incidental learning, adaptability, and shared visual working memory resources

Statistical properties in the visual environment can be used to improve performance on visual working memory (VWM) tasks. The current study examined the ability to incidentally learn that a change is more likely to occur to a particular feature dimension (shape, color, or location) and use this information to improve change detection performance for that dimension (the change probability effect). Participants completed a change detection task in which one change type was more probable than others. Change probability effects were found for color and shape changes, but not location changes, and intentional strategies did not improve the effect. Furthermore, the change probability effect developed and adapted to new probability information quickly. Finally, in some conditions, an improvement in change detection performance for a probable change led to an impairment in change detection for improbable changes.

Framing Persuasive Appeals: Episodic and Thematic Framing, Emotional Response, and Policy Opinion

Those seeking to frame political issues to their advantage recognize the power of emotional appeals. Yet the study of framing has focused mainly on the cognitive effects of framing rather than on its emotional effects. This study presents the results of two experiments designed to explore the effect of episodic and thematic framing on emotional response and policy opinion. Participants were randomly assigned to read a column arguing against mandatory minimum sentencing that employed either a thematic or one of two episodic frames featuring a woman who received a harsh sentence under the policy. Episodic framing was more emotionally engaging. Furthermore, the specific emotions elicited by the episodic frame—sympathy and pity for the woman featured in the column—were associated with increased opposition to mandatory minimum sentencing. Yet the thematic frame was actually more persuasive once this indirect effect of frame on emotional response was taken into account. The results are consistent with the conclusion that framing effects on policy opinion operate through both affective and cognitive channels. The theoretical and practical implications of the study are discussed.     

Semantic boost on episodic associations: an empirically-based computational model

Words become associated following repeated co-occurrence episodes. This process might be further determined by the semantic characteristics of the words. The present study focused on how semantic and episodic factors interact in incidental formation of word associations. First, we found that human participants associate semantically related words more easily than unrelated words; this advantage increased linearly with repeated co-occurrence. Second, we developed a computational model, SEMANT, suggesting a possible mechanism for this semantic-episodic interaction. In SEMANT, episodic associations are implemented through lateral connections between nodes in a pre-existent self-organized map of word semantics. These connections are strengthened at each instance of concomitant activation, proportionally with the amount of the overlapping activity waves of activated nodes. In computer simulations SEMANT replicated the dynamics of associative learning in humans and led to testable predictions concerning normal associative learning as well as impaired learning in a diffuse semantic system like that characteristic of schizophrenia.
