Several studies observed that a worse destination memory (i.e., capacity to remember to whom we said something) occurs when personal facts are shared, which was explained based on the internal attentional focus - the attentional focus is on the information and not on the recipient of the information. So, with two experiments, we aimed to mitigate the negative influence of the internal attentional focus on destination memory. Since it was previously observed that sharing information with distinctive faces leads to a better destination memory, in Experiment 1, participants (N = 30) were asked to transmit personal facts to distinctive and undistinctive faces. No differences were observed. To increase the attentional focus on the recipient of the information, in Experiment 2, participants (N = 30) were also asked to evaluate the distinctiveness of the recipients' faces. A better destination memory was not observed in Experiment 2 compared with Experiment 1. This leads us to conclude that asking participants to evaluate the faces did not promote a better destination memory when personal facts were shared. Nevertheless, by asking to evaluate the faces, the attentional focus was on the faces, where distinctive faces attracted more attention and led to a better destination memory.

Transgender individuals face challenges to identity as they transition from their sex assigned at birth to their affirmed gender. Memories may support a sense of self through the recall of events with more phenomenological detail than others, making them feel closer to the current self. Autobiographical memories of 90 transgender and 90 cisgender adults were compared on self-reported memory phenomenology. Memory phenomenology was more variable in transgender individuals, with a larger difference between phenomenological ratings of recent and distant memories. Memory phenomenology specifically varied in relation to the timing of coming out to a parent. High points reported after this time were rated with higher phenomenological quality and these ratings were linked to positive well-being. Results affirm the relevance of phenomenological continuity to the identity of transgender individuals, suggesting that events from before coming out are recalled with less phenomenological quality than events after coming out.

Learners can study foreign language-English vocabulary (e.g., denken - to think) both receptively and productively. Receptive learning involves being cued with a foreign language word (e.g., denken) and trying to translate it (i.e., to think). Productive learning involves being cued with an English word (e.g., to think) and trying to produce the translation. When students use retrieval practice to learn foreign-language translations in one direction (e.g., receptively) until they correctly recall the translation, do they demonstrate transfer in the other direction (i.e., productively)? Across three experiments, we answered this question by manipulating the order of learning schedule (reception first followed by production or vice versa). For a given schedule, participants continued to practice retrieving translations (with feedback) using the dropout method until they correctly recalled each translation three times; they then proceeded to practice the pairs in the opposite direction until they correctly recalled each translation three times. Across all experiments, transfer was partial (learning in one direction did not entirely eliminate the need to practice in the other), but transfer did occur regardless of which schedule students used first during practice.

It has been documented that older adults' memory deficits can be reduced for information depicted as personally and socially important (e.g., Hargis & Castel, 2017 [Younger and older adults' associative memory for social information: The role of information importance. Psychology and Aging, 32(4), 325-330]). The current study aimed to further assess the effects of both arbitrarily assigned and self-perceived importance in younger and older adults' memory for names (low in schematic support) and occupations (high in schematic support) associated with faces. Participants studied the same 16 face-name-occupation triplets (with neutral facial expressions) across four blocks, each including a free recall of names and occupations. At the end, they completed a cued recall of names and occupations. The faces were arbitrarily cued as socially important (i.e., with an orange frame) or unimportant (e.g., without a frame). The perceived social importance was assessed by rating all the triplets based on a 10-point Likert Scale (1 = least and 10 = most important) at the end. The results showed that age-related memory deficits were reduced or even eliminated for occupations (high in schematic support) relative to names (low in schematic support), especially in the free recall of faces self-perceived as important. In other words, the combination of schematic support and self-perceived importance can effectively mitigate older adults' memory deficit.

It is now well established that general information processing causes the activation of memories in the autobiographical memory system, and these memories on occasion emerge as involuntary autobiographical memories. This priming phenomenon has been dubbed semantic-to-autobiographical memory priming, and our goal in the current study was to examine the effects of cue/prime repetition on the production of involuntary autobiographical memories that were primed with semantic stimuli. In three experiments, participants were primed with words (e.g., cat), and then they were given an involuntary memory task (the vigilance task), which contained cues related to the primed stimuli. In Experiment 1, the cues were phrases containing the primes (e.g., getting a cat), which were presented one or five times. In Experiment 2, the cues were also phrases containing the primes (e.g., getting a cat), but they changed their context (e.g., feeding a cat), every time they repeated in the five-presentation condition. Experiment 3 also presented the cues one or five times, but the cues were replicas of the primes (e.g., cat). Consistent with predictions, greater priming was found in the five-presentation cue conditions in all three experiments, and Experiment 3 failed to find priming in the one-presentation cue condition, also consistent with predictions. We explain the findings in terms of semantic-to-autobiographical memory priming theory, and also argue that the results help explain the production of involuntary memories in everyday life.

In the present study, two experiments were conducted to examine whether thematic relation can produce recognition without cued-recall effect and whether the direction of the association has an influence on this effect. The participants provided higher familiarity ratings for studied items than for unstudied items during target retrieval failure. Additionally, the thematic relation-elicited recognition without cued-recall effect was larger in the forward association than in the backward association. Collectively, these results indicated that thematic relations can elicit the recognition without cued-recall effect, and this effect is asymmetrical. The current findings support the features overlap hypothesis described in the global match model.

According to recent theoretical work, certain event memories are more likely to be remembered or forgotten in their entirety. This prior work focused on collections of concepts, such as person-location-object triples. To explore this idea with complex materials, we created triples of people, locations, objects, or activities from events in real-world novels. People who had read one of the included novels were provided with one element from these triples (the cue) and asked to identify which of six alternatives best went with it. The results revealed that memory for the narrative events remained stable across many years. Moreover, people recalled events in a more holistic manner than would be expected by chance. This was more likely the more causally important an event was. This pattern of performance also remained stable over time. Our results are consistent with the idea that event models involve integrating separate elements into a single coherent representation, and this is likely to stay integrated over long periods of time. However, the degree to which this is so appears to be related to how well-integrated the information is within a larger set of events.

Multiple studies have explored the factor structure of working memory (WM) tasks, yet few have done so controlling for both the domain and category of the memory items in a single study. In the current pre-registered study, we conducted a large-scale latent variable analysis using variant forms of n-back and backward recall tasks to test whether they measured a single underlying construct, or were distinguished by stimuli-, domain-, or paradigm-specific factors. Exploratory analyses investigated how the resulting WM factor(s) were linked to fluid intelligence. Participants (N = 703) completed a fluid reasoning test and multiple n-back and backward recall tasks containing memoranda that varied across (spatial or verbal material) and within (verbal digits or letters) domain, allowing the variance specific to task content and paradigm to be assessed. Two distinct but related backward recall and n-back constructs best captured the data, in comparison to other plausible model constructions (single WM factor, two-factor domain, and three-factor materials models). Common variance associated with WM was a stronger predictor of fluid reasoning than a residual n-back factor, but the backward recall factor predicted fluid reasoning as strongly as the common WM factor. These data emphasise the distinctiveness between backward recall and n-back tasks.

Recognition memory, the ability to recognise previously encountered information, correlates with pupil diameter changes during the recognition period. This physiological response, known as the pupil old/new effect, generally reflects the variation in pupil dilation when encountering previously studied (old) stimuli compared to new stimuli. To develop a more precise understanding of the pupil old/new effect, we conducted a meta-analysis of 17 eye-tracking experiments (across 12 articles spanning from 2008 to 2023) involving 560 healthy adults with a mean age of 22.31 years. Analysis of publication bias showed a rather low risk of bias in the selected articles. The main meta-analysis revealed a significant and large pooled pupil old/new effect (Cohen's d_z = 0.73, 95% CI [0.50, 0.95]). Further analysis of moderators showed that the number of participants included in the experiments and the criteria for selecting trials (only correct trials vs. all trials) had a significant impact on the meta-analytic results. In general, the analyses revealed a robust pupil old/new effect across all selected articles. This finding underscores its potential utility as a marker of recognition memory across different stimuli type, and various experimental designs.

Memories for life events are thought to be organised based on their relationships with one another, affecting the order in which events are recalled such that similar events tend to be recalled together. However, less is known about how detailed recall for a given event is affected by its associations to other events. Here, we used a cued autobiographical memory recall task where participants verbally recalled events corresponding to personal photographs. Importantly, we characterised the temporal, spatial, and semantic associations between each event to assess how similarity between adjacently cued events affected detailed recall. We found that participants provided more non-episodic details for cued events when the preceding event was both semantically similar and either temporally or spatially dissimilar. However, similarity along time, space, or semantics between adjacent events did not affect the episodic details recalled. We interpret this by considering organisation at the level of a life narrative, rather than individual events. When recalling a stream of personal events, we may feel obligated to justify seeming discrepancies between adjacent events that are semantically similar, yet simultaneously temporally or spatially dissimilar - to do so, we provide additional supplementary detail to help maintain global coherence across the events in our lives.
