Vocal sounds, including both speech and non-speech sounds, have been found to activate the Superior Temporal Sulci and Gyri in comparison to non-vocal sounds. These regions, termed Temporal Voice Areas (TVAs), are considered to be involved in early voice processing and therefore critical for social interaction. TVA activation has been examined in Autism Spectrum Disorder (ASD) to determine if the characteristic difficulties in social communication and interaction are linked to an impaired early voice processing. Using functional magnetic resonance imaging (fMRI), one study found typical brain activation in TVAs for 15 out of 16 autistic participants (Schelinski et al., 2016), whereas another found atypical activation in 4 out of 5 autistic participants (Gervais et al., 2004).

 

Here, the inconsistencies in the previous literature propel Gautier et al. (2023) to examine brain activation of TVAs with a larger sample size (26 ASD and 26 non-ASD participants). Gautier et al. (2023) will present vocal sounds and non-vocal sounds to both groups of participants during fMRI and predict that fewer participants in the ASD group will show a preferential response to voices in TVAs compared to the non-ASD group. These results would suggest that symptoms of ASD interfere with early stages of social interaction, at the level of voice processing.

 

This Stage 1 manuscript was evaluated in an initial round by the co-recommenders and another two rounds of in-depth review by two expert reviewers. With these revisions, the recommenders judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

Visual symmetry is critical to our interaction with our environment so that when detected, symmetry automatically produces a neural marker in the form of an Event Related Potential (ERP) called Sustained Posterior Negativity (SPN). However, when symmetry is presented to the visual system slanted away from the viewer, there is a reduction in SPN, termed a perspective cost. 

 

Considering ​objects are rarely presented front-on (or frontoparallel) in our natural environment, Karakashevska et al., (2023) plan to examine the extent of the perspective cost with the addition of visual cues to facilitate extraretinal representation of the visual symmetry. The authors will record electroencephalography (EEG) from 120 participants while they perform a luminance task on symmetrical and asymmetrical stimuli. The authors hypothesize perspective cost will be reduced by three perspective cues: 1) monocular viewing, when cue conflict caused by binocular viewing is eliminated, 2) a static frame surrounding the symmetrical stimulus, adding a depth cue, and 3) a moving frame, assisting 3D perception prior to the symmetry onset. If the SPN is equivalent during frontoparallel and slanted presentation in a cue condition, the authors will conclude extraretinal representation can be automatic when sufficient visual cues are available. The proposed experiment is powered to detect a relatively small difference between perspective cue conditions. This will solidify fundamental research on visual symmetry processing and will further our understanding of object perception and recognition.

COVID-19 has been suspected to have long-lasting effects on cognitive function. The SARS-CoV-2 virus may enter the central nervous system (Frontera et al., 2020; Miners, Kehoe, & Love, 2020), explaining the observed detrimental effects of COVID-19 on verbal planning and reasoning (Hampshire et al., 2021; Wild et al., 2021), executive function (Hadad et al., 2022), and long-term memory (Guo et al., 2022). In particular, Guo et al. (2022) used verbal item recognition and non-verbal associative memory tasks. Weinerova et al. (2024), in the current study, propose to conduct a replication of Guo et al. (2022), but specifically, to disentangle the effect of COVID-19 infection status on both memory type (item vs. associative) and stimulus modality (verbal vs. non-verbal). Furthermore, Weinerova et al. (2024) propose to analyze cognitive function based on vaccination status before infection to provide a critical test of the potential protective effects of vaccination on cognitive function.

Data collection has been completed with 325 participants after exclusion criteria were applied (COVID group N = 232, No COVID group N = 93). Simulations assuming an effect size observed in Guo et al. (2022), a Bayesian t-test comparing the groups, and a Bayes Factor of 6 indicated that N = 320 is sufficient to detect an effect on 79% of simulations. The main analyses will be conducted using a Bayesian ANCOVA that allows for the inclusion of control variables such as age, sex, country, and education level. Both accuracy and reaction times from the item and associative recognition tasks will be analyzed as the dependent variables. In one analysis, vaccination status will be included as a between-subjects factor, to understand whether vaccination status at the time of infection influences subsequent cognitive function. 

It is important to note that participants were recruited through long-COVID Facebook groups and clinics. Therefore, the results must be interpreted carefully to avoid generalizing to all COVID-19 infections. The data are part of a larger longitudinal study, and the current pre-registration applies only to the baseline timepoint for a cross-sectional analysis. The remaining longitudinal data collection is ongoing and is not part of the current pre-registration.  

The study plan was refined after one round of review, with input from three external reviewers who all agreed that the proposed study was well-designed 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).

Paid loot boxes, i.e. randomised monetization methods that are similar to lottery-type gambling, have become prominent features of contemporary gaming (e.g., Macey & Bujić, 2022). Because the design structures of loot boxes vary and the value of their virtual rewards is not always clear-cut, many countries now struggle how to deal with them legally and in practice (see Drummond et al., 2020). Belgium is one of the few countries that have officially interpreted loot box monetization to widely belong under gambling regulation. Mobile games that monetize with paid loot boxes in Belgium should thus apply for a gambling license, and companies should generally not offer paid loot boxes to local underage players at all.
 
In this Stage 1 Registered Report, Xiao (2022) has constructed a careful plan for testing whether the “ban” in Belgium has made the local mobile game market distinct in terms of paid loot boxes. The work builds on a rapidly accumulating literature and evolving methods (e.g., Xiao et al., 2021). The author will carry out a systematic qualitative investigation of the country’s top 100 (iPhone) mobile games to investigate whether paid loot box design components have indeed been removed from the products -- and if not, whether related game companies operate with a required gambling license. Additionally, Xiao (2022) will assess Belgium’s overall paid loot box prevalence in comparison to other countries and carry out a field experiment to test whether players can easily circumvent the local regulation by transporting or downloading different versions of software.
 
The study will produce valuable evidence regarding the effectiveness of loot box regulation in general, and more specifically, the results should be of utmost interest to Belgian legal authorities. To ensure the transparency and validity of the chosen methods as well as upcoming interpretations, the registered report format allowed the research design to be reviewed in three rounds before data collection. Three experts, representing the fields of law and gaming, reviewed the Stage 1 manuscript twice and agreed upon the acceptance of all details. Finally, the recommender carried out a third iteration with further requested revisions, which was followed by in-principle acceptance. 

 

When interviewing members of a criminal network, what determines the information a given interviewee chooses to disclose, as guided by the network's collective planning? What principles could help inform a detective preparing for such interviews? In the current study, Neequaye et al. recruited groups of people known to each other to assume the role of networks that run an illegal sports betting business, fronting as a chain of tanning salons. Although each network launders money, they have to come up with a strategy to convince investigators they are legit. The groups are motivated to disclose some information when individuals are interviewed, but only enough to appear cooperative. Members disclosed information they perceived would yield benefical outcomes, but the extent to which members disclosed varied substantially according to the groups they were in.

 

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.
