Can one-shot learning be elicited from unconscious information?

Can unconscious experience drive perceptual learning?

Recommended by ORCID_LOGO based on reviews by Jeffrey Saunders and 1 anonymous reviewer
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).

Sight vs. sound judgments of music performance depend on relative performer quality: Cross-cultural evidence from classical piano and Tsugaru shamisen competitions [Stage 2 Registered Report]

Music is appreciated cross-modally, but is culture- and context-dependent

Recommended by ORCID_LOGO based on reviews by Kyoshiro Sasaki and 1 anonymous reviewer
Music is not merely limited to the aural experience we garner through our auditory faculties, as commonly perceived. Rather, various studies have explored the cross-modal impact of visual stimuli on the evaluation of music. These previous studies have been confined exclusively to Western music. Hence, Chiba et al. (2023) designed a study with a focus on the Tsugaru shamisen, a renowned folk instrument indigenous to Japan, and of which the first author is an outstanding player.

The study methodology was an improved version of previous endeavors, wherein actual musical material sourced from concours performances was displayed through audio-only, video-only or both modalities. A sample of Japanese participants were then asked to evaluate the concours performances on both the piano and the Tsugaru shamisen. The results, obtained through pre-registered protocols, revealed that for both concours performances, the participants displayed a cross-modal impact of visual information on their aural evaluation of music. This effect was also found to be contingent on cultural and contextual factors. These outcomes furnish valuable evidence towards the generalizability of the interplay between sight and sound in the assessment of music.
 
The study underwent rigorous peer-review processes in both Stage 1 and Stage 2, with three experts specializing in Japanese folk music, open science, and statistics, respectively, providing their critical assessments. Following multiple rounds of revision, the final manuscript was deemed fit for recommendation.

One and only SNARC? A Registered Report on the SNARC Effect’s Range Dependency

Is the SNARC effect modulated by absolute number magnitude?

Recommended by ORCID_LOGO based on reviews by Melinda Mende and 1 anonymous reviewer
The Spatial-Numerical Association of Response Codes (SNARC) effect refers to the fact that smaller numbers receive faster responses with the left hand, and larger numbers with the right hand (Dehaene et al., 1993). This robust finding implies that numbers are associated with space, being represented on a mental number line that progresses from left to right. The SNARC effect is held to depend on relative number magnitude, with the mental number line dynamically adjusting to the numerical range used in a given context. This characterisation is based on significant effects of relative number magnitude, with no significant influence of absolute number magnitude. However, a failure to reject the null hypothesis, within the standard frequentist statistical framework, is not firm evidence for the absence of an effect. In this Stage 1 Registered Report, Roth and colleagues (2023) propose two experiments adapted from Dahaene’s (1993) original methods, with a Bayesian statistical approach to confirm—or rule out—a small effect (d = 0.15) of absolute number magnitude in modulating the classic SNARC effect.
 
The study plan was refined across two rounds of review, with input from two external reviewers and the recommender, after which it was judged to satisfy the Stage 1 criteria for in-principle acceptance (IPA).

Hormonal Contraceptive Use and Women’s Sexuality and Well-Being: Estimating Treatment Effects and Their Heterogeneity Based on Longitudinal Data

The Causal Effects of Hormonal Contraceptives on Psychological Outcomes

Recommended by ORCID_LOGO based on reviews by Summer Mengelkoch and 2 anonymous reviewers
Ensuring universal access to sexual and reproductive health and reproductive rights is a global concern, exemplified by goal 5.6 of the Sustainable Development Goals (UN General Assembly, 2015). Whilst the range of contraceptive options have increased, our understanding of the impacts of use for women are inadequate and represent a key barrier to positive change in policies and practices. In particular, we have few consensuses on the expected impacts of hormonal contraceptive use on women's sexuality and wellbeing.
 
In the current programmatic submission, Botzet et al. (2023) argue that this inconclusive evidence base could be due to the wide heterogeneity in responses, the impacts of this heterogeneity upon attrition, differences in contraceptive methods and dosage effects, confounders, and the potential for reverse causality. Tackling some of these potential factors, Botzet (2023) explore whether hormonal contraceptive use influences sexuality and well-being outcomes, and whether (and to what extent) the effects vary between women. To achieve this they have proposed analysis of longitudinal data from the German Family Panel (PAIRFAM) which includes annual waves of data collection from >6500 women, with separate Stage 2 submissions planned to report findings based on sexuality and well-being. The proposed work will progress our understanding of the impact of hormonal contraceptives by overcoming limitations of more common research approaches in this field, and has the potential to contribute to a more contextualised view of the impact of their impacts in real-world practice.

Do Ecological Valid Stop Signals Aid Detour Performance? A Comparison of Four Bird Species

What is the role of sensory perception in cognitive task performance? An improved replication of detour performance in four different bird species

Recommended by ORCID_LOGO based on reviews by 2 anonymous reviewers
The detour task, where an individual has to navigate around a see-through barrier in order to reach a goal, is one of the oldest paradigms used in animal cognition research (Kabadayi et al. 2018). While these previous tests have documented variation in the ability of animals to inhibit going straight for the visible but blocked reward, the cognitive underpinnings of this behaviour are as yet not fully understood. In the current study, Dewulf et al. (2023) propose to assess one of the specific cognitive processes that might be involved in this behaviour. Through experimental procedures, they will compare the role of signal detection in inhibitory response performance in a detour task. To assess whether variation in detection of the barrier might be linked to the ecological niche of a species, they will compare four bird species who live in different environments. Individuals from these four species were previously tested in a detour task (Regolin et al. 1994, Zucca et al. 2005), and the proposed research plan therefore also involves a partial replication of previous studies on the same issue, but improving some critical aspects.

Registered Report: Are anticipatory predictions enhanced in tinnitus and independent of hearing loss?

Can predictive coding explain subjective tinnitus?

Recommended by ORCID_LOGO based on reviews by Will Sedley, Pia Brinkmann and Emilie Cardon
Subjective tinnitus is a common disorder in which people experience a persistent sound in the absence of any external source. The underlying causes of tinnitus are debated – although the condition is strongly associated with hearing loss resulting from auditory damage, much remains to be understood about the neural processes that give rise to the phantom perception. Various classes of neurophysiological theories have been proposed, including the “altered gain” model – in which neurons in the auditory pathway increase their responsiveness to compensate for reduced auditory input following hearing loss – and the “noise cancellation” model –  in which disrupted feedback connections from limbic regions are unable to tune out phantom signals. Although these theories account for much observed data, they have not been conclusively supported, and their ability to explain tinnitus is limited by the fact that hearing loss and tinnitus can arise independently and at different times.
 
In the current study, Reisinger et al. (2023) will test an emerging alternative theory based on a Bayesian predictive-coding framework (Sedley et al., 2016) in which the alteration of perceptual priors leads the auditory system to expect a sound that, if functioning normally, it should not expect. Using magnetoencephalography (MEG) in a sample of tinnitus patients (and carefully-matched controls for age, gender, and level of hearing loss), they will ask whether tinnitus is associated with anticipatory brain activation, tuned to the carrier-frequency of an expected auditory stimulus. Specifically, the authors predict that if the predictive-coding framework is correct then individuals with tinnitus should show different regularity-dependent pre-activations of carrier- frequency-specific information compared to the control group, while tone carrier-frequencies should be processed normally in tinnitus patients. They also predict that any such pre-activations should not be related to levels of reported subjective tinnitus distress, as measured with the short version of the Tinnitus Questionnaire (mini-TQ).

Causal evidence for the role of the sensory visual cortex in visual short-term memory maintenance

The visual cortex can maintain information for up to a second

Recommended by ORCID_LOGO based on reviews by Evie Vergauwe and Vincent van de Ven
According to the sensory recruitment framework, the visual cortex is at least in part responsible for maintaining information about elementary visual features in visual short term memory. Could an early visual area, constantly taking in new information, really be responsible for holding information for up to a second? But conversely, could higher order regions, such as frontal regions, really hold subtle sensory distinctions? It must be done somewhere. Yet the existing evidence is conflicting. Phylactou et al. addressed this question by applying transcranial magnetic stimulation (TMS) to disrupt early visual areas at intervals up to a second after stimulus presentation to determine the effect on visual short term memory performance. In this way, they causally influenced the sensory cortex at relevant times while tightening up on possible confounds in earlier research.
 
They found that TMS applied to the occipital hemisphere at each of 200ms and 1000ms after presentation of a brief visual stimulus disrupted stimuls detection on a visual short term memory test. These findings support sensory recruitment, which claims that both perceptual and memory processes rely on the same neural substrates in the visual cortex.

Optimizing Esports Performance Using a Synergistic Mindsets Intervention

Synergistic Mindset Intervention for Competitive Situations

Recommended by ORCID_LOGO based on reviews by Lee Moore, Ivan Ropovik , Ivana Piterová and Jacob Keech
Mindset theories suggest that the mere belief in the malleability of human abilities can already help one to develop related performance. On the other hand, one and the same performance situation can also be experienced in various affective ways, which differently contribute to performance outcomes. Arguably, appraising a performance situation as a “threat” instead of “challenge” is associated with maladaptive responses, such as impaired cardiovascular mobilization. If people could experience performance situations as positive challenges, this might also improve performance outcomes. Drawing from these connected theoretical premises, the synergistic mindset intervention was developed and tentatively found to help adolescents in stressful situations (Yeager et al., 2022).
 
In the present registered report, Behnke et al. (2023) build on the above and test whether the synergistic mindset intervention can help individuals in competitive gaming situations. The authors utilize one of the leading esport games, Counter-Strike: Global Offensive​, and recruit its active players into randomized control and intervention groups for two weeks. Ultimately, the participants compete in a cash-prize tournament involving measures of affective experience and cardiovascular responses. Behnke et al. (2023) hypothesize that the synergistic mindset group will show greater challenge affective responses and superior performance outcomes. As such, the study design has significant potential to generate valuable evidence for various theoretical models and the synergistic mindset model in particular.

Cortical plasticity of the tactile mirror system in borderline personality disorder

Is borderline personality disorder linked to impairment of the tactile mirror system?

Recommended by ORCID_LOGO based on reviews by Zoltan Dienes and 2 anonymous reviewers
Borderline personality disorder (BPD) is a mental illness affecting ~1 in 100 people (Ellison et al., 2018), characterised by emotional dysregulation, impulsivity, a distorted sense of self, and a long-term pattern of unstable interpersonal relationships. Among this heterogenous range of symptoms is difficulty in the cognitive dimension of empathy, in particular understanding the perspectives of others, which in turn has been suggested to rely on the mirror neuron system, both in the motor and somatosensory domains. The integrity of the mirror system has therefore been a focus for understanding the possible causes or consequences of the disorder, with preliminary studies pointing to hypoactivity of neuronal areas associated with the mirror system in BPD (Mier et al., 2013).
 
In the current study, Zazio et al. (2023) will use crossmodal paired associative stimulation (cm-PAS) in which an image of a hand being touched is repeatedly paired with transcranial magnetic stimulation (TMS) of the primary somatosensory cortex (S1) to test the hypothesis that BPD is associated with a specific deficit in the tactile mirror system. In healthy controls, the close temporal coupling (20ms) between the visual depiction of tactile stimulation and TMS of S1 is expected boost tactile acuity and elevate the performance cost of incongruence in a task that manipulates visuo-tactile spatial congruity (VTSC) – effects that are thought to reflect the fidelity of the tactile mirror system.
 
In BPD patients, however, the authors make the crucial prediction that impairment of the tactile mirror system (if present) will lead to a reduced (or even non-existent) effect of cm-PAS on tactile acuity and VTSC task performance compared to healthy controls. To help ensure a severe test of this hypothesis, the design includes a variety of controls, including an attention check, control cm-PAS in which the inter-stimulus interval is increased to 100ms to break the close temporal coupling between visual stimulation and TMS, and a positive control to confirm that active cm-PAS (compared to control cm-PAS) produces the expected boost in tactile acuity in healthy controls.

Stress is a familiar presence in modern life and may be rising in severity (Almeida et al., 2020). As a key driver of many health problems, controlling stress and its impacts is a central goal in clinical and health psychology, yet the effectiveness of existing interventions to regulate stress remains unclear. 
 
In the current study, Sparacio et al tackled this question from a meta-analytic perspective, focusing on a corpus of existing research that has addressed the efficacy of two specific stress regulation interventions: being in nature and emotional social support. As well as evaluating the evidential content of the relevant literatures, the authors also examined signs of publication bias and the moderating role of personality traits.
 
After correcting for publication bias, the results reveal evidence that being in nature is effective at reducing stress while emotional social support is not. The moderating role of personality for both interventions was inconclusive due to lack of evidence. In addition, the quality of the surveyed literature was found to be low overall, suffering from a high risk of bias and high rate of statistical reporting errors. The authors offer several recommendations to improve the rigour and quality of studies in this field, including open data, open materials, code review, preregistration and the use of Registered Reports.
 
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Level of bias control achieved: Level 3. At least some data/evidence that was used to the answer the research question had been previously accessed by the authors (e.g. downloaded or otherwise received), but the authors certify that they did not observe ANY part of the data/evidence prior to Stage 1 IPA.
