Research suggests elaborative rehearsal encoding manipulations facilitate subsequent recall of to-be-learned information. Though there have been several proposed mechanisms to understand this effect, we wanted to explore whether elaborative rehearsal may additionally be understood to improve memory via a reduction in mind wandering during learning. In a pre-registered experiment, we had participants learn a list of sentences in which a person was tied to an arbitrary action. In the control condition, a plausible explanation was provided to link person and action while in the elaborative rehearsal condition, participants were tasked with generating their own explanation. During this list presentation, participants were presented with several probes to gauge whether their attention was on task or if instead their mind had wandered to off-task thoughts. Later, participants were given a cued-recall test in which they were asked to recall which person was associated with each action. Results revealed that participants in the elaborative rehearsal condition recalled more of the sentences and self-reported less mind wandering. However, contrary to predictions, the reductions in mind wandering did not mediate cued recall performance. We argue that these data suggest elaborative rehearsal improves memory primarily because of what it adds (rich, idiosyncratic retrieval paths) as opposed to what it suppresses.

Retrieval-induced forgetting (RIF) refers to the finding that selective retrieval practice of a subset of studied items can impair recall of related unpracticed items, relative to recall of unrelated control items. Using categorized study material, we examined in two experiments how the retention interval between retrieval practice and test (1 min, 4 h, 24 h, or 7 d) influences the size of this RIF effect. Across both experiments, the RIF effect was robust at shorter retention intervals (1 min, 4 h) but disappeared at longer intervals (24 h, 7 d). Unlike prior work, we also fitted power functions of time to the recall rates of unpracticed and control items to examine forgetting rates of the two types of items. Analysis of the function's parameters showed that while unpracticed items were initially impaired, they were forgotten more slowly over time than control items, making RIF disappear at longer retention intervals. Results are discussed with respect to prominent accounts of RIF.

Two psychosocial work models, job demand-control (JDC) and effort-reward imbalance (ERI), have been studied in relation to health and cognition, but to a limited extent with subjective memory. This study aimed to evaluate longitudinal associations of JDC and ERI with changes in subjective memory among United States (U.S.) workers from the population-based Midlife in the United States (MIDUS) study. Among 1,538 U.S. workers, generalised estimating equations analyzed associations of independent and joint JDC and ERI categorizations at baseline (2004-2006) with changes in subjective memory composite scores from baseline to follow-up (2013-2014). Multivariable modelling accounted for demographic, socioeconomic, lifestyle, health, and psychosocial work factors. In the fully adjusted models, high job control (regression coefficient: 0.151 [95% CI 0.038, 0.264], p = 0.0088), "high demand and high control" (0.164 [0.015, 0.312], p = 0.0313), high reward (0.289 [0.174, 0.405], p < .0001), "low effort and high reward" (0.288 [0.130, 0.446], p = 0.0004), and "high effort and high reward" (0.288 [0.128, 0.448], p = 0.0004) were associated with increased subjective memory. Work-related control and reward were positively associated with subjective memory changes across nine years among a U.S. worker cohort. Future research may support workplace environment improvements to promote cognitive health.

Schacter (1999, 2001) has provided a taxonomy for studying memory distortions that suggests there are seven "sins" of memory: misattribution, persistence, suggestibility, bias, absent-mindedness, blocking, and transience. Although there has been a great deal of evidence that these memory distortions occur among individuals, few studies have examined the effects of discussion on false memories. In the present study, we presented seven memory tasks, each designed to elicit a different memory sin, to participants who either encoded the information individually or engaged in discussion within groups of 2 or 3 while retrieving the information. We found widespread evidence of all seven memory sins, whether participants engaged in discussion during retrieval or not. Group discussion increased actual memory for information. Regarding memory sins, group discussion increased misattribution and persistence, and decreased transience. Discussion had no significant effect on suggestibility, bias, absent-mindedness, or blocking. We discuss implications for situations where people attempt to retrieve memories while discussing them.

Prospective memory is the ability to remember to perform a planned activity in a future situation. Because of the strong sociability of older adults, their prospective memory performance is easily affected by prosocial motivation. The purpose of this study was to explore the influence of prosocial motivation on prospective memory and its components in older adults. Specifically, we recruited 101 older adults (aged 60-75 years) and 115 younger adults (aged 18-25 years) to participate in this experiment. We used a 2 (group) × 2 (age) × 2 (attention load) between-subjects design. Prosocial motivation was induced by instruction. The results showed that, compared with the control group, the accuracy of prospective memory and ongoing task in the prosocial motivation group was higher under different attention load and age conditions. Concurrently, the response speeds of the prospective memory and the ongoing tasks were slower. The results from the beta-MPT model analysis showed that under the condition of low attention load, the prospective component of the prosocial motivation group was higher than that of the control group. The results showed that prosocial motivation could promote prospective memory performance of both older adults and younger adults, an outcome unaffected by attention load. Prosocial motivation mainly ensures the monitoring and confirmation of prospective memory cues in high attention load condition by slowing down the response speed of both younger and older adults, thus improving prospective memory performance. The registration number is ChiCTR2500105119.

The present study examined conditions under which negative autobiographical memories are narrated with redemptive themes, a normative narrative structure in the U.S., in which a negative or emotionally difficult life experience is described as having a positive conclusion. U.S. college student participants were asked to provide a written essay of a negative autobiographical experience. They were randomly assigned to experimental conditions that varied in memory-sharing context (highly evaluative versus less evaluative) and exposure to normative narrative modelling (redemptive sample essays versus nonredemptive sample essays). Results indicated that evaluative social context and redemptive narration exposure each increased participants' use of redemptive narration when recalling negative autobiographical memories. Use of redemption, in turn, led to more positive evaluations of the essays by independent raters, highlighting the social efficacy of using culturally normative narrative structures in interpersonal contexts.

This study explores the factors influencing the perceived significance of public events among middle-aged adults in Turkey, focusing on the role of political identity. A representative sample of participants from various regions of Turkey (329 females, Mage = 47.26, SD = 1.82; 330 males, Mage = 47.37, SD = 1.83) assessed various characteristics of public events. The results showed that personal significance, relevance to national identity, political significance, and unexpectedness were the strongest predictors of event significance, while emotional impact and consequentiality did not significantly predict perceived significance. Political identity also influenced perceptions, with supporters of the ruling AKP (Justice and Development Party) and opposition CHP (the Republican People's Party) showing different priorities in event significance. Additionally, higher SES was linked to greater perceived significance of events, while higher education was associated with lower significance ratings. These results highlight the complex interplay between political identity, demographic factors, and event characteristics in shaping public event perception.

When retrieving information, people often shift over time from "Remembering" high levels of detail about a study episode to simply "Knowing" the information absent such detail. This "Remember-Know" shift is well-documented for true information, and recent work suggests that this effect exists, but is attenuated, for false information. One explanation for this difference is that true information is better represented in people's prior knowledge, supporting retention of this content as "Known" over time. In this registered report we tested this hypothesis by measuring people's reported retrieval experiences (e.g., "Remembering" or "Knowing") for true and false information at two levels of anticipated prior knowledge. While we replicate the "Remember-Know" shift, we do not find that it differs by anticipated prior knowledge. We also examine the relation between retrieval experiences and the production of encountered information, as well as the impact of repeated testing on retrieval experiences.

We investigated age-related differences and commonalities in earliest memories, focusing on retrieval speed, recollection type (remember vs. know), retrieval type (direct vs. generative), age at the time of the event, and phenomenological characteristics. The sample consisted of 131 adults: 68 young adults (48.5% males; M_age = 20.29, Sa_ge = 1.53) and 63 older adults (47.6% males; M_age = 68.43, SD_age = 4.11). They reported their earliest memories, estimated their age at the time, indicated recollection and retrieval types, and rated event characteristics (e.g., importance, vividness). Results showed that older adults were significantly more likely to classify their memories as remembered and directly retrieved, whereas young adults had a more balanced distribution of the classifications. Directly retrieved memories were accessed more rapidly than generatively retrieved ones, and young adults demonstrated shorter retrieval latencies than older adults. Additionally, older adults dated their earliest memories to later age and rated them as significantly more vivid, emotionally intense, and personally meaningful. Recollection type was not associated with retrieval latency but linked to higher vividness and confidence. Overall, our findings demonstrate potential age-related shifts in the retrieval and subjective evaluation of earliest autobiographical memories.

Although previous research has extensively examined the characteristics of specific autobiographical memories, few tools have been available to assess how individuals recall their personal past in general. To address this gap, we adapted into Polish the Autobiographical Recollection Test (ART), a self-report instrument originally designed to capture general autobiographical remembering across seven components: vividness, narrative coherence, reliving, rehearsal, scene construction, visual imagery, and life story relevance. Confirmatory factor analysis supported the factorial validity of the Polish version, demonstrating adequate psychometric properties. The Polish adaptation also showed expected correlations with another self-report measure of autobiographical memory ability (Survey of Autobiographical Memory, SAM), supporting its convergent validity. Furthermore, both the full and brief versions of ART showed significant associations with scores on the Involuntary Autobiographical Memory Inventory (IAMI). These findings provide robust support for the Polish adaptation of ART as a reliable tool for assessing the subjective qualities of autobiographical memory, with potential applications in research on diverse populations.
