Unconscious priming effects have fascinated not just psychologists but also ad-makers and consumers alike. A related phenomenon in perception is illustrated by presenting participants with two-tone images, which are degraded versions of images of objects and scenes. These two-tone images look like and are indeed judged as meaningless dark and light patches. Upon presenting the actual template image, however, the two-tone image is accurately recognized. This perceptual learning is abrupt, robust, and long-lasting (Daoudi et al., 2017). Surprisingly, Chang et al. (2016) showed that such perceptual disambiguation of two-tone images can happen even in the absence of conscious awareness of having seen the template image. 

 

Halchin et al. (2023) in the current study propose to conduct a conceptual replication of Chang et al. (2016) with important modifications to the procedures to address limitations with the earlier work. Specifically, there was no explicit manipulation of levels of conscious awareness of the template images in the original study. Therefore, miscategorization of low-confidence awareness as unaware could have led to an erroneous conclusion about unconscious priors guiding perceptual learning. Such miscategorization errors and how to tackle them are of interest to the broader field of consciousness studies. Furthermore, a conceptual replication of Chang et al. (2016) is also timely given that prior related work suggests that masking impairs not only conscious awareness of visual features but also blocks processing of higher-level information about the images (e.g. object category). 

 

To address the issues identified above, Halchin et al. (2023) propose to experimentally manipulate conscious awareness by masking the template image very quickly (i.e., a short stimulus onset asynchrony; SOA) or by allowing some more time to induce weak and strong conscious awareness, respectively. The SOAs were validated through pilot studies. Furthermore, they include a four-point perceptual awareness scale instead of the original yes/no options to gauge participants’ subjective awareness of the template images. The authors also propose multiple experiments to include different ways of testing participants’ objective ability to identify the masked template images. Last but not least, the proposed design includes a stronger control condition than the original study by using masked images created from related images (e.g. belonging to the same semantic category). Depending on the results obtained in the main experiments, the inclusion of this control allows the authors to conduct a third experiment to investigate whether the results in the first two can be explained by semantic priming. The proposed study is sufficiently powered (as demonstrated through simulations), and Bayesian statistical procedures will be used to test the main hypotheses. In summary, the proposed work offers a significant improvement in terms of experimental procedures over the original study. If the Chang et al. (2016) results are replicated, the stronger design in the current study is likely to lead to a better understanding of the mechanisms underlying unconscious priors guiding perceptual learning. On the other hand, a failure to replicate not just Chang et al. (2016)’s results but also effects across the three experiments in the current study would raise legitimate questions about the reality of unconscious information guiding perceptual learning. 

 

The study plan was refined across two rounds of review, with input from two external reviewers who both agreed that the proposed study is well designed, timely, and scientifically valid. The recommender then reviewed the revised manuscript and judged that the study met the Stage 1 criteria for in-principle acceptance (IPA).

In the past two decades, most academic fields have witnessed an open science revolution that has led to significant increases in open access publishing, reproducibility efforts, and scientific transparency in general (e.g., Spellman et al. 2018). One of the key areas in this ongoing change is data sharing. Although some evidence already points at progress in data sharing practices, many new datasets remain unshared (see Tedersoo et al. 2021).
 
In the present registered report, Henderson et al. (2023) empirically explore the factors that either hinder or facilitate data sharing in the UK. By means of semi-structured interviews, the team will chart researchers’ experiences of sharing and non-sharing. Thematic template analysis will be applied to organise the data into a hierarchical map of capabilities, opportunities, and motivations in a theoretical domains framework (COM-B-TDF). The research plan itself meets the highest open science standards and reflects on the authors own positions, from which the current qualitative interview data sharing efforts will be made.
 
The Stage 1 manuscript was reviewed over three rounds by three experts with familiary of the UK cultural context and specializations in open science practices, qualitative research, and data infrastructures. Based on careful revisions and detailed responses to the reviewers’ comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.

Words have served as stimuli in memory experiments for over a century. What makes some words stand out in memory compared to others? One plausible answer is that semantically rich words are more distinctive and therefore exhibit a mirror effect in recognition memory experiments where they are likely to be correctly endorsed and also less likely to be confused with other words (Glanzer & Adams, 1985). Semantic richness can arise due to extensive prior experience with the word in multiple contexts but can also arise due to sensorimotor grounding, i.e., direct perceptual and action-based experience with the concepts represented by the words (e.g. pillow, cuddle). However, previous experiments have revealed inconsistent recognition memory performance patterns for words based on different types of sensorimotor grounding (Dymarska et al., 2023). Most surprisingly, body-related words such as cuddle and fitness exhibited greater false alarm rates. 

In the current study, Dymarska and Connell (2023) propose to test two competing theories that can explain the increased confusability of body-related words: 1) the adaptive account - contextual elaboration-based strategies activate other concepts related to body and survival, increasing confusability; and 2) the attentional account - somatic attentional mechanisms automatically induce similar tactile and interoceptive experiences upon seeing body-related words leading to less distinctive memory traces. The adaptive account leads to different predictions under intentional and incidental memory conditions. Specifically, contextual elaboration strategies are unlikely to be employed when participants do not expect a memory test and therefore in an incidental memory task, body-related words should not lead to inflated false alarm rates (see Hintzman (2011) for a discussion on incidental memory tasks and the importance of how material is processed during memory tasks). However, the attentional account is not dependent on the task instructions or the knowledge about an upcoming memory test. 

Here, Dymarska and Connell (2023) have designed an incidental recognition memory experiment with over 5000 words, disguised as a lexical decision task using carefully matched pseudowords during the encoding phase. The sample size will be determined by using a sequential hypothesis testing plan with Bayes Factors. To test the predictions of the adaptive and attentional accounts, the authors derive a set of lexical and sensorimotor variables (including a body-component) after dimensionality reduction of a comprehensive set of lexical and semantic word features. The analysis will involve running both Bayesian and frequentist hierarchical linear regression to explain four different measures of recognition memory performance based on the key sensorimotor variables and other baseline/confounding variables. While this analysis plan enables a comparison with the earlier results from an expected memory test (Dymarska et al., 2023), the current study is self-contained in that it is possible to distinguish the adaptive and attentional accounts based on the effect of body component scores on hit rate and false alarm rate.

The study plan was refined across two rounds of review, with input from two external reviewers after which the recommender judged that the study satisfied the Stage 1 criteria for in-principle acceptance (IPA).

In 2023, the journal eLife ended the practice of making binary accept/reject decisions following peer review, instead sharing peer review reports (for manuscripts that are peer-reviewed) and brief “eLife assessments” representing the consensus opinions of editors and peer reviewers. As part of these assessments, the journal draws language from a "common vocabulary" to linguistically rank the significance of findings and strength of empirical support for the article's conclusions. In particular, the significance of findings is described using an ordinal scale of terms from "landmark" → "fundamental" → "important" → "valuable" → "useful", while the strength of support is ranked across six descending levels from "exceptional" down to "inadequate".

 

In the current study, Hardwicke et al. (2023) question the validity of this taxonomy, noting a range of linguistic ambiguities and counterintuitive characteristics that may undermine the communication of research evaluations to readers. Given the centrality of this common vocabulary to the journal's policy, the authors propose a study to explore whether the language used in the eLife assessments will be interpreted as intended by readers. Using a repeated-measures experimental design, they will tackle three aims: first, to understand the extent to which people share similar interpretations of phrases used to describe scientific research; second, to reveal the extent to which people’s implicit ranking of phrases used to describe scientific research aligns with each other and with the intended ranking; and third, to test whether phrases used to describe scientific research have overlapping interpretations. The proposed study has the potential to make a useful contribution to metascience, as well as being a valuable source of information for other journals potentially interested in following the novel path made by eLife.

The Virtual Maze Task (VMT) is a digital desktop 2D spatial learning task that has been used for research into the effect of sleep and dreaming on memory consolidation (e.g. Wamsley et al, 2010). One limitation of this task has been low rates of reported dream incorporation. Eudave and colleagues (2023) have created an immersive virtual reality (iVR) version of the VMT, which they believe might be more likely to be incorporated into dreams. As an initial step in validating this task for research, they propose a within-subjects study to compare three measures of spatial learning between the 2D desktop and iVR versions. Based on a review of relevant literature, the prediction is that performance will be similar between the two task versions. The planned sample size (n = 62) is sufficient for a .9 power test of equivalence within effect size bounds of d = -.47 to .47. Additional independent variables (gender, perspective-taking ability) and dependent measures (self-reported cybersickness and sense of presence) will be recorded for exploratory analyses.
