Researchers have recently demonstrated that people tend to experience spontaneous mental simulations of what might happen next - i.e., the approximal future - and that such simulations are especially likely to focus on possible negative outcomes in relation to sources of perceived threat in the surrounding environment. The purpose of the two studies (N = 318) reported in this manuscript was to better characterise the generalizability of simulations of the approximal future across the lifespan. Participants were asked to report memories of approximal simulations of the future and to indicate whether the events they reported were triggered by any relevant past experiences. Across both studies, we found consistent evidence that people, irrespective of age, remember simulations of the approximal future that are disproportionately characterised by negative as opposed to positive valence, and that these memories tend to be remembered as being triggered by some relevant personal, vicarious, or media event. These findings suggest that mental simulation and memory work flexibility to support threat detection.

In today's digital world, people are documenting their lives more extensively than ever before. To investigate how this pervasive (digital) documentation shapes the way individuals reconstruct and recall personally relevant events, we conducted a preregistered experimental think-aloud study in which participants (N = 40; German sample) were asked to remember their birthdays from 2019 and 2024 in as much detail as possible. Participants completed the study in their usual home environments and were allowed to consult any external resources that they wanted to consult. The results demonstrate that participants almost exclusively used digital external resources. Moreover, participants relied more heavily on external resources when recalling the more distant birthday. Importantly, the use of external resources was an overall adaptive strategy, insofar as it helped participants gain new insights that went beyond what they could recall from internal memory alone. This provides further evidence that integrating information stored in one's mind and information stored in the environment is a potentially beneficial and symbiotic process.

Encoding lists of categorised words produces robust false memory for non-presented exemplars but few false memories for category labels. The present research examined the conditions under which categorical false memories can be elicited by variations in list composition in which a subset of category labels was presented for half of the lists. In Experiment 1, participants encoded lists of exemplars with or without the presence of category labels under full or divided attention conditions. Presentation of a subset of category labels produced false memories for non-presented labels and dividing attention reduced this effect. In Experiment 2, participants encoded lists as in Experiment 1 and prior to retrieval, were (or were not), given warnings about the nature of false memory effects and to avoid false memory errors. Categorical false memories arose when a subset of labels was encoded and warnings did not significantly reduce their magnitude, testifying to the robustness of this effect. Explanations are considered from the perspective of activation monitoring, fuzzy trace theory and how encoding and subsequent monitoring interact.

Recovered memories (RM) of trauma remain a contentious issue in psychological research and clinical practice, with ongoing debates about their prevalence and validity. This systematic review synthesizes empirical evidence from 42 studies published post-2000, following the "Memory Wars", to examine the prevalence of RM and associated contextual factors across diverse populations. Prevalence rates vary significantly: 1-3% in legally documented childhood sexual abuse (CSA) cases, 22-39% in self-reported CSA survivor samples, 6-19% in therapy attendees, and 3-13% in general population samples. Variability is driven by differences in operational definitions (e.g., total amnesia vs. partial forgetting), sample types, and recovery contexts (e.g., therapy-induced vs. spontaneous triggers). Therapist reports indicate 27-78% have encountered clients with RM, with caseload proportions ranging from 0.56% to 20%, influenced by theoretical orientation and training. Purposive studies reveal no unique cognitive mechanisms for RM, with experiences often reflecting conscious suppression, meta-awareness failures, or environmental cueing rather than special dissociative processes. These findings support a reconstructive memory framework, emphasizing cognitive, motivational, and environmental factors. The review highlights the need for standardized definitions, cross-cultural research, and enhanced therapist training to address risks of suggestive practices and develop evidence-based guidelines for supporting clients reporting RM in the absence of concerns regarding suggestion.

Research on the saying-is-believing effect shows that individuals tune their messages to match the audience's attitude and subsequently exhibit memory bias in the same direction. However, its implications in the context of collective memory remain understudied. Drawing on social identity theory, prior research suggests that people reconstruct memories of their group's past selectively, emphasising positive aspects and minimising negative ones. Using a 2 × 2 factorial design, this study examined the saying-is-believing effect in national history by manipulating audience attitude (positive vs. negative) and message production (with vs. without message generation). Results show that the effect extends to national history, with participants tuning their messages and biasing their memory according to the audience's attitude. However, those high in nationalism showed neither message tuning nor memory bias. These findings suggest that for individuals high in nationalism, social identity motivations override the epistemic and relational motives that typically drive the saying-is-believing effect.

To examine contrasting predictions between fuzzy trace theory (FTT) and activation monitoring theory (AMT), the current study examined the proportion of DRM false memories produced by children vs adults. In contrast to previous studies, backward associative strength (BAS) was well controlled, and the method ensured that subjects' attention was focused on lexical/semantic information. Specifically, DRM lists for children were constructed from child norms, and DRM lists for adults were based on adult norms. In addition, to ensure that attention was focused on lexical/semantic information, lists were read aloud to the subjects, and responses were made verbally. Children produced more false memories than adults, supporting AMT. Response modality was varied in a second Experiment. Children recalled more items when responding orally than when writing responses. Adults showed no effect of response modality. These results indicate that when BAS is controlled, and both children's and adults' attention is focused on semantic information, false memory occurs more frequently in children than adults. We propose that this pattern is indicative of a less developed attentional system in children, is consistent with activation monitoring theory, and suggests important boundary conditions for the occurrence of developmental reversals.

The noncriterial recollection hypothesis (Brewer, G. A., Marsh, R. L., Clark-Foos, A., & Meeks, J. T. (2010). Noncriterial recollection influences metacognitive monitoring and control processes. Quarterly Journal of Experimental Psychology, 63(10), 1936-1942. https://doi.org/10.1080/17470210903551638) posits that feeling-of-knowing judgments (FOKs) are influenced by the retrieval of learned contextual information, but the effects of emotional contexts remain unexplored. We examined how the amount and emotional content of contextual information affect FOKs. Participants studied face-name pairs presented alone (no-information), with a description of a disgusting/neutral behaviour (medium-information), or with both the person's profession and the disgusting/neutral behaviour (maximum-information). We assessed cued recall, FOKs, and recognition accuracy for the face-name pairs. We hypothesised that additional contextual information would increase FOK magnitude, with a more pronounced effect for emotional content. The results revealed a dissociation between memory and metamemory, indicating a metacognitive illusion. Medium and maximum information conditions increased FOKs but reduced recall and recognition rates relative to the no-information condition. We observed no direct effect of emotion; FOK magnitude did not differ between negative and neutral conditions across information levels. However, correctly identifying which faces were associated with disgusting behaviours contributed more to FOKs than identifying which faces were associated with neutral behaviours. Overall, this study supported the noncriterial recollection hypothesis and extends research on emotion and metamemory. Moreover, we show a memory-metamemory dissociation with stimuli relevant in everyday life.

Utilising a two-character Chinese compound words list as task material, this study examines the effects of three combinations of deep and shallow encoding levels (operationalised via semantic and perceptual tasks, respectively) of two members within the same collaborative group on collaborative retrieval and subsequent individual memory. During the encoding phase, both the collaborative group and the nominal group conducted independent semantic or perceptual encoding. In the retrieval phase, the collaborative group engaged in collaborative retrieval and post-collaborative individual retrieval using three encoding combinations: semantic + semantic, perceptual + perceptual, and semantic + perceptual, while the nominal group continued with individual retrieval. The results indicate that the combination of differing encoding levels (semantic + perceptual) not only eliminates collaborative inhibition and reduces erroneous retrieval during collaborative retrieval but also enhances individual memory performance post-collaboration. This improvement reflects two complementary mechanisms: differentiated encoding levels reduce strategy interference, while cross-cueing facilitates reciprocal cueing between deep and shallow encoders, enabling them to leverage each other's retrieval strengths and optimise collaborative performance.

Knowledge builds through direct experiences (e.g., teaching) and productive processes (e.g., analogy). There is variability in the specific productive process of self-derivation of new knowledge through integration of separate yet related episodes of new learning. The variability relates to each of four hypothesised precursor sub-processes: encoding, reactivation, integration (all three for both children and adults), and selection (tested in children only). However, relations between each sub-process and self-derivation have been investigated in separate samples. As such, how they work together to support self-derivation is unknown. In the current research, we investigated all four sub-processes in samples of 7-11-year-olds (Study 1) and college-age adults (Study 2). In the child sample and in the combined sample of children and adults, encoding, reactivation, and integration each were found to relate to self-derivation; selection was not related to self-derivation. In the children sample and in the combined sample of children and adults, cluster analyses revealed two paths to successful self-derivation, one of which was more prompt-independent and the other seemingly was dependent on prompts. There also were two paths to unsuccessful self-derivation, both characterised by low success at encoding. The results provide new insight into sources of variability in self-derivation through memory integration.

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.
