Does retrieval practice protect memory against stress? A meta-analysis [Stage 1 Registered Report]

Can retrieval practice prevent the negative impact of acute stress on memory performance?

Recommended by ORCID_LOGO based on reviews by Chris Hartgerink (they/them) and Adrien Fillon
There are a number of broad assumptions about memory which have penetrated societal understanding and mostly reflect supporting academic evidence e.g., that acute stress can compromise memory performance (Shields et al., 2017) and that practicing recalling critical information can help retain that knowledge (Moriera et al., 2019). The evidence base is less consistent when evaluating whether retrieval practice can protect against the negative effects of acute stress on memory, despite it being highly important for educators as to whether this specific strategy for supporting memorisation can be evidenced as especially effective under stressful conditions. A rigorous review of this mixed evidence base could provide the basis for developments in memory theory and research practice, with potential for direct educational applications.
 
Meta-analyses can play a critical role in furthering our understanding of complex cognitive mechanisms where the evidence base includes a wide range of methods, factors and effect size estimates. Furthermore, there is a lack of rigorous meta-analyses that prioritise open and reproducible processes (Topor et al., 2022) which help role-model good practice. In the current Registered Report, Mihaylova et al. (2024) have proposed a rigorous meta-analysis to systematically review and synthesise the evidence on the effects of retrieval practice for memory performance under acute stress. The work looks to be especially valuable for a) informing future research directions through a structured risk of bias evaluation, and b) generating theoretical developments through a range of confirmatory moderators (including stressor types, memory strategies, time of delay and task type). The findings of the planned analyses are expected to be of immediate interest to educational and occupational domains where memory recall is a priority.

Does ‘virtuality’ affect the role of prior expectations in perception and action? Comparing predictive grip and lifting forces in real and virtual environments

The role of prior expectations for lifting objects in virtual reality

Recommended by ORCID_LOGO based on reviews by 2 anonymous reviewers
As virtual reality environments become more common, it is important to understand our sensorimotor interactions with them. In real world settings, sensory information is supplemented by prior expectations from past experiences, aiding efficient action control. In VR, the relative role of expectations could decrease due to a lack of prior experience with the environment, or increase because sensory information is impoverished or ambiguous. Harris, Arthur and Buckingham (2024) propose to test these possibilities by comparing a real-world object lifting task and a VR version in which the same objects are lifted but visual feedback is substituted by a virtual view. The experiment uses the Size-Weight Illusion (SWI) and the Material Weight Illusion (MWI). In these paradigms, the visual appearance of the object induces expectations about weight that can affect the perception of weight during lifting, and the fingertip forces generated. The degree to which the visual appearance of objects induces differences in perceived weight, and in measured fingertip forces, will index the influence of prior expectations for these two paradigms. The analyses will test whether the influence of prior expectations is lower or higher in the VR set-up than in real-world lifting. The outcomes across tasks (SWI and MWI) and measures (perceived weight, fingertip forces) will broaden our understanding of the role of predictive sensorimotor control in novel virtual environments.

Do individual differences in cognitive ability or personality predict noticing in inattentional blindness tasks?

Are individual difference in inattentional blindness related to cognitive abilities or personality traits?

Recommended by ORCID_LOGO based on reviews by Ruben Arslan and 1 anonymous reviewer
Despite inattentional blindness being a widely recognized and researched phenomenon — popularized by experiments like the invisible gorilla — the evidence on how individual differences affect the occurrence of inattentional blindness has remained inconsistent, largely due to small sample sizes and methodological variations.
 
In this context, Daniel J. Simons, known for his role in bringing public attention to inattentional blindness, along with Yifan Ding, Connor M. Hults, and Brent W. Roberts, presents an ambitious yet well-constructed registered report that addresses this critical gap in the literature. Their report outlines a comprehensive investigation into whether individual differences in cognitive ability or personality traits can predict the likelihood of noticing unexpected objects in various inattentional blindness tasks. The two proposed studies — one focusing on cognitive predictors and the other on personality predictors — arguably represent the most extensive single-sample tests to date on this topic.
 
The authors propose a robust methodology that includes a total of 2,000 participants (1,000 per study). The study design features three distinct inattentional blindness tasks with varying levels of demand to assess the generalizability of the findings across different experimental contexts. In Study 1, cognitive measures such as matrix reasoning and operation span — both well-established indicators of fluid intelligence and working memory — are utilized. Study 2 incorporates a range of personality measures, including the Big Five personality traits and attention-related traits (e.g., ADHD and obsessive-compulsive characteristics).
 
The report also presents a detailed analysis plan with pre-specified primary and secondary outcomes, strong justifications for the sample size, and clearly defined criteria for data inclusion and exclusion. The authors intend to employ multiple statistical techniques, such as correlation analyses and regression models, along with rigorous checks for replicability, to explore the relationship between individual differences and inattentional blindness.
 
Overall, this registered report is a well-justified and meticulously planned investigation into the role of individual differences in inattentional blindness. The proposed studies have the potential to make a significant contribution to our understanding of the cognitive and personality factors that influence the noticing of unexpected objects. The rigorous experimental design, large sample sizes, and adherence to open science practices make this a valuable addition to the literature.

Based on the strengths of the proposal and the authors' responsiveness to the detailed feedback from two reviewers, the recommender justed that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

Do pain and effort increase prosocial contributions?: Revisiting the Martyrdom Effect with a Replication and extensions Registered Report of Olivola and Shafir (2013)

More pain, more prosocial? Assessing the Martyrdom Effect

Recommended by ORCID_LOGO based on reviews by Vanessa Clemens and Liesbeth Mann
The Martyrdom Effect is a behavioral tendency in which individuals exhibit greater generosity when their acts of giving entail effort or self-sacrifice (Olivola & Shafir, 2013). Giving at a personal cost, in this mindset, is associated with ascribing and inferring more meaning and value to charitable giving or other forms of generosity than in instances where no particular pain or effort is required to enact prosocial behavior. Arguably, the Martyrdom Effect’s ability to boost prosocial behavior therefore departs from other theories of behavior change postulating that easy options to act prosocially could boost contributions (e.g., default effects in charitable giving, see Altmann et al., 2019; Goswami & Urminsky, 2016). Because they introduce complexity to the debate about encouraging prosocial behavior, three studies from Olivola and Shafir (2013) are now being addressed in this Registered Report by Cheng and Feldman (2024).

Combining these three studies in a high-powered within-subjects replication attempt, transparently communicating necessary deviations from the original design and carefully outlining the analysis strategy, the current study will offer insights into the robustness of prior findings on the role of effort and pain in determining donations.

Do prediction errors of perceived exertion inform the level of running pleasure?

Running pleasure results from finding it easier than you thought you would

Recommended by ORCID_LOGO based on reviews by Jasmin Hutchinson and 1 anonymous reviewer
The reward value of a stimulus is based on an error in prediction: Things going better than predicted. Could this learning principle, often tested on short acting stimuli, also apply to a long lasting episode, like going for a run? Could how rewarding a run is be based on the run going better than predicted?
 
Understanding the conditions under which exercise is pleasurable could of course be relevant to tempting people to do more of it! In the current study, Brevers et al. (2024) asked people before a daily run to predict the amount of perceived exertion they would experience; then just after the run, to rate the retrospective amount of perceived exertion actually experienced. The difference between the two ratings was the prediction error. Participants also rated their remembered pleasure in running. As hypothesized, the authors found that running pleasure increased linearly with how much retrospective exertion was than predicted.
 
The Stage 2 manuscript received one round of review from two external reviewers, then some minor comments from the recommender, after which it was judged to satisfy the Stage 2 criteria and was awarded a positive recommendation.

Do Scarcity-Related Cues Affect the Sustained Attentional Performance of the Poor and the Rich Differently?

How does economic status moderate the effect of scarcity cues on attentional performance?

Recommended by ORCID_LOGO based on reviews by Ernst-Jan de Bruijn and Leon Hilbert
This Stage 1 registered report by Szecsi et al. (2024) seeks to clarify whether individuals' economic conditions moderate how scarcity cues affect their attentional performance. This idea has been previously explored: Here, the authors aim to clarify understanding of the how scarcity cues affect cognition by studying a large and diverse Hungarian sample with improved experimental methods.
 
Specifically, while it has been previously reported that financially less well-off individuals' are differentially affected by finance-related stimuli (e.g. Shah et al., 2018), Szecsi et al. (2024) argue that prior studies have used small samples with insufficient consideration of potentially important demographic variables. Therefore, the generalizability of prior studies might be lacking.
 
Second, Szecsi et al. (2024) aim to conduct a more realistic experiment by asking participants to free-associate in response to financial scarcity-related cues, whereas prior studies have often focused on simply querying for rating responses, which might not sufficiently engage the related cognitive mechanisms that could be most affected.
 
In the proposed study, then, the authors will rigorously test whether financially less well-off individuals have lower attentional performance while experiencing scarcity-related cues than individuals who are financially better off, and that attentional performance does not differ while experiencing non-scarcity related cues. Ultimately, Szecsi et al. propose to shed light on theories of scarcity-related cognition that posit overall decrements in attentional performance irrespective of individuals' financial status.
 
The Stage 1 manuscript was initially reviewed by two experts in the area, who both recommended several improvements to the study. The authors then thoroughly revised their write-up and protocol, and the two reviewers were satisfied with the substance of these revisions. Based on these evaluations, the recommender judged that the Stage 1 criteria were met and awarded in-principle acceptance. There were remaining editorial clarifications and suggestions which the authors can incorporate in their eventual Stage 2 report.

Dose-response of tDCS effects on motor learning and cortical excitability: a preregistered study

How stimulation intensity affects motor learning

Recommended by ORCID_LOGO based on reviews by Charlotte Wiltshire and 1 anonymous reviewer
In neurostimulation research, the parameters of a stimulation protocol crucially impact on the effects of the stimulation. Transcranial direct current stimulation (tDCS) is a neurostimulation technique that typically uses current intensities about 1-2 mA in human research to modulate motor and cognitive behavior. The current sham-controlled study by Hsu et al. (2024) applies current intensities not only of 2 mA but also of 4 mA and 6 mA and thus extends our understanding of stimulation parameters while ethical standards are preserved.
 
The influence of tDCS over the primary motor cortex will be evaluated for neural plasticity during motor learning. Stimulation effects will be tested not only behaviorally but also physiologically by motor evoked potentials elicited by transcranial magnetic stimulation (TMS). The presented pilot data are promising and underline the feasibility of the proposed research design. The study will contribute to tDCS research by uncovering reasons for controversial findings and thus increase reproducibility.

Do task-irrelevant cross-modal statistical regularities induce distractor suppression in visual search?

Learning cross-modally to suppress distractors

Recommended by ORCID_LOGO based on reviews by Miguel Vadillo and 1 anonymous reviewer
There are two fundamental processes that the brain engages in: statistical learning and selection. Indeed, past work has shown these processes often come together: People can use a task-irrelevant stimulus to predict a target stimulus even in different modalities (crossmodal statistical learning), thereby enhancing the processing of the target stimulus (selection). Further, people can learn where a distractor will be in order to efficiently suppress it (selecting out), using task irrelevant stimuli in the same modality (within-modality statistical learning).
 
In the current study, Jagini and Sunny will test whether people can learn where a distractor stimulus is, in order to suppress it (selecting out), using a task-irrelevant stimulus from a different modality (cross modal statistical learning). They will also test whether people can express awareness of the relation between the predictor task-irrelevant stimulus and the location of the distractor on a forced choice test. On some (but not other) theories of consciousness, such a test measures conscious knowledge of the association.

Effects of Auditory Stimuli During Submaximal Exercise on Cerebral Oxygenation

Does listening to music alter prefrontal cortical activity during exercise?

Recommended by ORCID_LOGO based on reviews by David Mehler and 1 anonymous reviewer
The relationship between music and exercise has been studied for over a century, with implications for our understanding of biomechanics, physiology, brain function, and psychology. Listening to music while exercising is associated with a wide range of benefits, from increasing motivation, to reducing perceived exertion, inhibiting awareness of negative bodily signals, boosting mood, and ultimately improving physical performance. But while these ergogenic benefits of music are well documented, much remains to be discovered about how music alters brain function during exercise. One reason for this gap in understanding is the technical difficulty in recording brain activity during realistic exercise, as neuroimaging methods such as fMRI, EEG or MEG typically require participants to remain as still as possible.
 
In the current study, Guérin et al. (2023) will use the optical brain imaging technique of functional near infrared spectroscopy (fNIRS) to measure oxygenation of key brain areas during exercise. Unlike other neuroimaging methods, fNIRS has a high tolerance for motion artefacts, making it the ideal method of choice for the current investigation. The authors propose a series of hypotheses based on previous studies that observed a decrease in cerebral oxygenation during intense exercise, particularly within the medial prefrontal cortex (mPFC) and dorsolateral prefrontal cortex (dlPFC). If, as suggested, the prefrontal cortex is important for regulation of cognition and emotion during exercise, then the benefits of listening to music might arise by delaying or reducing this drop in prefrontal oxygenation.
 
Using a within-subject designs, Guérin et al. will combine an incremental exercise protocol involving a cycling task with three auditory conditions: asynchronous music (the active condition), listening to an audiobook (an auditory control) or silence (baseline control). Compared to the two control conditions, they predict that music exposure will increase oxygenation in prefrontal and parietal regions and will also delay the drop in oxygenation associated with intense exercise (specifically within dlPFC and mPFC). To test whether any such changes are specific for prefrontal and parietal cortex, they will also compare the haemodynamic responses of the occipital cortex between the auditory conditions, predicting no difference.

Estimating the Effect of Reward on Sleep-Dependent Memory Consolidation – A Registered Report

How does reward influence the effect of sleep on memory?

Recommended by ORCID_LOGO based on reviews by 2 anonymous reviewers
Sleep and reward each have an important role in human memory. According to the active system consolidation hypothesis, memory consolidation during sleep originates from the repeated reactivation of memory representations that were encoded during wake (Rasch & Born, 2013). Research has also consistently shown that memory performance is enhanced for items or stimuli associated with higher vs. lower rewards. While these lines of evidence are relatively clear, the role of sleep in shaping the interaction between reward and memory is more opaque, likely due to a combination of methodological variation between studies but also due to the field’s reliance on small-N designs and biased reporting practices. Clarifying this three-way relationship, and setting field benchmarks for effect sizes, is crucial not only for building richer neurocognitive models of memory, but for clinical applications such as targeted sleep interventions to treat addiction and other forms of mental illness. 
 
Using a large, stratified online German sample (N=1750), Morgan et al. (2022) will study the three-way relationship between sleep, reward and memory by asking whether, and if so how, reward influences the magnitude of sleep-dependent memory consolidation. Using an AM:PM-PM:AM design in combination with a motivated learning task, the authors will address three main questions: first, whether sleep yields greater memory performance compared to an equivalent period of wake; second whether information associated with higher reward leads to greater memory performance compared to lower reward; and third, the crucial interaction of whether sleep causes greater recognition memory performance for higher vs. lower reward items. The design also includes a series of rigorous positive controls to confirm testability of the hypotheses, while measuring a host of additional moderating variables for exploratory analyses (including age, education status, mental health, and more).
