In response to the replication crisis in psychology, the scientific community has advocated open science practices to promote transparency and reproducibility. Although existing reviews indicate inconsistent and generally low adoption of open science in psychology, a current-day, detailed analysis is lacking. Recognising the significant impact of false memory research in legal contexts, we conducted a preregistered systematic review to assess the integration of open science practices within this field, analysing 388 publications from 2015 to 2023 (including 15 replications and 3 meta-analyses). Our findings indicated a significant yet varied adoption of open science practices. Most studies (86.86%) adhered to at least one measure, with publication accessibility being the most consistently adopted practice at 73.97%. While data sharing demonstrated the most substantial growth, reaching about 75% by 2023, preregistration and analysis script sharing lagged, with 20-25% adoption in 2023. This review highlights a promising trend towards enhanced research quality, transparency, and reproducibility in false memory research. However, the inconsistent implementation of open science practices may still challenge the verification, replication, and interpretation of research findings. Our study underscores the need for a comprehensive adoption of open science to improve research reliability and validity substantially, fostering trust and credibility in psychology.

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.

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.

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.

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.

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.

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.

We present the first study to measure the beliefs held by Italian laypeople about how human memory works, using a newly developed tool: the Italian Memory Belief Questionnaire (IMBQ). Research conducted in other countries has demonstrated that beliefs about memory vary widely between different professional and non-professional groups, indicating that limitations exist regarding the dissemination of empirically researched scientific knowledge. To ascertain what Italian people understand about memory-related topics, including eyewitness testimony, repression of traumatic memories and factors influencing memory recall, 301 native Italian participants completed the IMBQ in Study 1. In Study 2, 346 additional participants completed the IMBQ, alongside various additional measures, to examine the construct validity of our new instrument and investigate socio-demographic predictors of memory beliefs. Exploratory factor analysis in Study 1 identified three distinct belief factors that were present in the dataset: eyewitness and memory reliability, trauma and remembering and aspects that improve remembering. Study 2 partially confirmed this factor structure and found IMBQ scores to correlate with existing memory belief questionnaires. Correlations were also found between the IMBQ subscales and measures of fantasy proneness, but not dissociation. In both studies, many Italian laypeople strongly endorsed the notion that controversial topics (i.e., repression) are possible. Contrastingly, Italian laypeople do appear to understand the conceivable inaccuracies of memory in eyewitness settings. Sex, age and education were shown to predict beliefs about memory. Findings are discussed in relation to the importance of addressing misinformation about memory, especially in clinical and forensic settings.

Selectively remembering more valuable information can improve memory efficiency. Such value effects have been observed on long-term memory for item-colour binding, but the possible contributory factors are unclear. The current study explored contributions from attention (Experiment 1) and verbal rehearsal (Experiment 2). Across two experiments, memory was superior for item-colour bindings that were associated with high (relative to low) point values at encoding, both in an immediate test and a delayed re-test. When availability of attentional resources was reduced during encoding, value only influenced immediate and not delayed memory (Experiment 1). This indicates that a transient value effect can be obtained with little attentional resources, but attentional resources are involved in creating a longer lasting effect. When articulatory suppression was implemented during encoding (Experiment 2), value effects were somewhat reduced in the immediate test and abolished in the delayed re-test, suggesting a role for verbal rehearsal in value effects on item-colour binding memory. These patterns of value effects did not interact with encoding presentation format (i.e., sequential vs. simultaneous presentation of objects). Together, these results suggest that attentional resources and verbal rehearsal both contribute to value effects on item-colour binding memory, with varying impacts on the durability of these effects.

ABSTRACTIntentional forgetting of unwanted information is a crucial cognitive function that is often studied with directed forgetting (DF) procedure, whereby cuing some study materials with Forget (F) instruction impairs their memory compared to cuing with Remember (R) instruction. This study investigates how the nature of information (verbal or pictorial), its semantic significance (meaningful or meaningless), and the degree of prior episodic familiarity influence DF. Before the DF phase, stimuli were familiarised by pre-exposing them 0, 2, or 6 times in a prior preview phase. Finally, memory for all items was assessed with old/new recognition test. Experiment 1 employed words, Experiment 2 utilised fractal images, Experiment 3 featured both meaningful and meaningless object images, and Experiment 4 used words and nonwords. Our results indicate that materials that produced better memory performance are not always harder to intentionally forget. Previewed items showed reduced DF compared to non-previewed items regardless of the nature of information, and meaningless stimuli are challenging to intentionally forget regardless of their degrees of familiarisation unless they are meaningless verbal materials. Collectively, the results highlight the importance of joint consideration of the stimulus format, its meaningfulness, and its episodic familiarity in understanding conditions that interact with intentional forgetting.
