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

Can the visual cortex maintain information in the short term?

Recommended by ORCID_LOGO based on reviews by Robert McIntosh, 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. seek to address 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 will causally influence the sensory cortex at relevant times while tightening up on possible confounds in earlier research.

Exploring How Members of Illicit Networks Navigate Investigative Interviews

What to say to help one's partners in crime

Recommended by ORCID_LOGO based on reviews by Tom Ormerod and Lorraine Hope
When interviewing members of a criminal network, what determines what 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. will recruit 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. The relation of the amount of different sorts of information disclosed depending on estimated risks and benefits for the group will be tested.

Revisiting mental accounting classic paradigms: Replication of Thaler (1999) and an extension examining impulsivity

Mental accounting under the microscope

Recommended by ORCID_LOGO based on reviews by Barnabas Szaszi and Féidhlim McGowan
In recent years, the study of mental accounting – the thought processes by which people informally record, categorise, and evaluate the costs and benefits of their financial transactions – has been an active research area, drawing attention to a range of biases and distortions that deviate from optimal economic decision-making (Zhang & Sussman, 2018). Although the term “mental accounting” is a relatively recent construction (Thaler, 1999), it stems from a longer history of behavioural economic research on value functions, decision frames, risk-taking, and related concepts.
 
In the current study, Li and Feldman propose to replicate 17 influential mental accounting problems (or tasks) reviewed by Thaler (1999) in a large online sample. The authors also propose several extensions examining the effects of sunk costs and expenses framing.

Revisiting the links between numeracy and decision making: Replication of Peters et al. (2006) with an extension examining confidence

Assessing the replicability of specific links between numeracy and decision-making

Recommended by ORCID_LOGO based on reviews by Daniel Ansari and Elena Rusconi
Numeracy – the ability to understand and work with numbers – is associated with a wide range of social and health-related outcomes, including socioeconomic status, employment, literacy, reasoning, and life satisfaction. A substantial body of evidence has also shown links between numeracy and decision-making, prompting the question of how it relates to finer-grained measures of reasoning, judgment and affect/emotion.
 
In the current study, Zhu and Feldman propose to replicate four influential experiments from a study by Peters et al. (2006), which demonstrated links between numeracy and performance on a variety of decision-making tasks, including attribute framing, frequency-percentage framing, susceptibility to affective influences, and various cognitive biases. The authors also propose several extended questions, including refinements of the original hypotheses and an examination of the relationship between numeracy and confidence in numeric judgments (subjective numeracy).

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.

Is the past farther than the future? A registered replication and test of the time-expansion hypothesis based on the filling rate of duration

Could asymmetrical perceptions about the frequency of past and future events explain the Temporal Doppler Effect?

Recommended by ORCID_LOGO based on reviews by Chris Chambers and 2 anonymous reviewers
The Temporal Doppler Effect is a phenomenon where people subjectively perceive the past to be further away than the future even when both temporal distances are objectively the same from the present moment (Caruso et al., 2013). A common explanation for this phenomenon assumes that our perception of the past and future is based on spatial and temporal analogies (Matlock, Ramscar, & Boroditsky, 2005; Casanto & Boroditsky, 2008) and that the subjective discrepancy is due to people feeling that they are moving towards the future and away from the fast, thus underestimating the temporal distance of the former and overestimating the temporal distance of the latter (Caruso et al., 2013).
 
In the current study, Zhang et al. propose to replicate the Temporal Doppler Effect as tested by Caruso et al. (2013) in study 1 and to test an alternative explanation for the effect in study 2 based on the filled-duration illusion (Thomas & Brown, 1974). This alternative explanation assumes that the subjective discrepancy is based on the difference that the past and the future are filled with events that we can remember or imagine. Because the past has already happened, it is comprised of more events (those that were planned and those that were not), while the future still exists only of events that are currently planned. 
 
The Stage 1 manuscript was evaluated over three rounds of in-depth review. The main changes during the review process involved clarifications and adaptations of the way that the authors will measure the participants’ perception of how full of events the past and the future are, as the originally proposed way measuring this did not have sufficient theoretical or empirical justifications. The authors decided to address this by firstly, clarifying this issue in the stage 1 report so that the reader is aware of the potential shortcomings of this measure, and secondly, by testing a second group of participants with an alternative measure. Based on detailed responses to the reviewers’ comments and edits to the stage 1 report, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Breaking Ban: Assessing the effectiveness of Belgium’s gambling law regulation of video game loot boxes

Has the “ban” of loot boxes eliminated them from Belgian mobile games?

Recommended by ORCID_LOGO based on reviews by Andrew Moshirnia, Joseph Macey and Jason Chin
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.

Stage 1 Registered Report: Stress regulation via being in nature and social support in adults - a meta-analysis

Does emotional support and being in nature influence stress?

Recommended by ORCID_LOGO based on reviews by Felix Schönbrodt and Siu Kit Yeung

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 propose tackling 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 will examine signs of publication bias and the moderating role of personality traits.

The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Neuroanatomical Correlates of System-justifying Ideologies: A Pre-registered Voxel-based Morphometry Study on Right-Wing Authoritarianism and Social Dominance Orientation

What are the neuranatomical correlates of system-justifying ideologies?

Recommended by ORCID_LOGO based on reviews by Bonni Crawford and 2 anonymous reviewers

Under the tenets of system justification theory, system-justifying ideologies are beliefs held by individuals to defend and justify the status quo, even when doing do perpetuates social inequalities (Jost and Hunyady, 2005). Two such well-studied ideologies to emerge from political science and social psychology are social dominance orientation (SDO) – the belief that some social groups are superior to others – and right wing authoritarianism (RWA) – the belief that people should follow conventional traditions and authorities, avoiding rebellious ideas. Although considered to be stable traits that may have a heritable basis, there has been little investigation of the neural correlates of SDO and RWA, and it remains unknown whether they are associated with common or distinct brain systems.

In the current study, Balagtas et al propose a novel investigation of the neuroanatomical correlates of both SDO and RWA in a Chinese Singaporean sample using voxel-based morphometry. Based on previous research, the authors focus especially on relationships between SDO, RWA and the volume of the amygdala, ventromedial prefrontal cortex, and anterior insula. 

The Stage 1 manuscript was evaluated over three rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

This submission has been withdrawn (see notice below)

Sex-biased dispersal is widely acknowledged to influence range expansion and the geographic limits of species (Trochet et al. 2016). Evidence is accruing that suggests an impact of the learning ability of species on their capacity to colonise new habitats because the ability to learn provides an advantage when confronted to novel challenges (Lee and Thornton 2021). Whether these two mechanisms interact to shape range expansion remains however unknown. One could expect this interaction because both dispersal and the ability to learn are linked to related behaviours (e.g., exploration, Lee and Thornton 2021). 

In their study entitled “Investigating sex differences in learning in a range-expanding bird”, Alexis J. Breen and Dominik Deffner (Breen and Deffner 2022) propose to test this hypothesis in range-expanding great-tailed grackles (Quiscalus mexicanus) by exploring the individual variation of several behavioural traits (e.g., exploration, neophobia, problem solving, Logan 2016) linked to their learning ability. They will use a colour-reward reinforcement experimental approach to compare the learning performance between male and female great-tailed grackles in three study sites and evaluate whether sex-biased learning ability interacts with sex-biased dispersal. Data will be analysed by a Bayesian reinforcement learning model (Deffner et al. 2020), which was validated.
