Using Shakespeare to Answer Psychological Questions: Complexity and Mental Representability of Character Networks

Complexity of Shakespeare’s Social Networks

Recommended by ORCID_LOGO based on reviews by Matúš Adamkovič, James Stiller, Tomáš Lintner and Matus Adamkovic
The rapid methodological development in digital humanities keeps opening new possibilities to better understand our cultural artifacts and, in the process, also ourselves. Some of the historically most influential works of literary human culture are the plays of Shakespeare, which continue to be read and treasured around the world. Although the social networks of Shakespeare’s plays have attracted scientific attention already more than two decades (Stiller et al. 2003), the understanding of their complexity in terms of character networks remains limited and not fully contextualized in the larger landscape of European drama.
 
In the present registered report, Thurn and colleagues (2024) apply Kolmogorov complexity analysis to investigate the social networks in 37 existing plays of Shakespeare. The authors replicate the original work by Stiller et al. (2003) and situate the findings in a larger regional context by further analyzing over 3,000 plays available in the European Drama Corpus. Ultimately, the authors explore the relationships between (Kolmogorov) complexity and the size of character networks as well as the robustness of their results in relation to possible researcher decisions in the analytic process.
 
This Stage 1 manuscript was evaluated over three rounds of in-depth review by four expert reviewers from the research fields of literature, networks, and social analysis. Based on the authors’ careful revisions and responses to the reviewers’ feedback, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Functional MRI brain state occupancy in the presence of cerebral small vessel disease -- a pre-registered replication analysis of the Hamburg City Health Study

Replicable dynamic functional connectivity and cognitive correlates of cerebral small vessel disease in the Hamburg City Health Study

Recommended by ORCID_LOGO based on reviews by 1 anonymous reviewer
In a previous analysis of data from 988 participants in the Hamburg City Health Study (HCHS), Schlemm and colleagues (2022) reported significant associations between the extent of cerebral small vessel disease (cSVD) and dynamic functional connectivity measures from resting state fMRI. Specifically, the volume of white matter hyperintensities of presumed vascular origin, a structural indicator of cSVD, was negatively related to the proportion of time (‘fractional occupancy’) spent in the two most occupied functional brain states. Reduced fractional occupancy was also associated with longer times to complete part B of the Trail Making Test.
 
In the present Registered Report, Ingwersen and colleagues (2023) successfully replicated these associations between structural, functional and cognitive measures in a sample of 1651 HCHS participants not included in the earlier study. An exploratory multiverse analysis found that the associations were generally robust to different brain parcellation and confound regression strategies. These replicable patterns reinforce the idea that cSVD may disrupt the brain’s ability to enter and maintain distinct functional modes, and that these changes in functional dynamics are predictive of cognitive impairment.

A systematic review of social connection inventories

Improving the measurement of social connection

Recommended by ORCID_LOGO based on reviews by Jacek Buczny, Richard James and Alexander Wilson
This is an ambitious systematic review that uses a combination of quantitative and qualitative methods to make the measurement of the construct of social connection more rigorous. Social connection is a heterogeneous construct that includes aspects of structure, function and quality. Here, Paris et al. (2024) will use predefined methods to create a database of social connection measures, and will assess heterogeneity of items using human coders and ChatGPT. This database will form the basis of a second systematic review which will look at evidence for validity and measurement properties. This study will also look at the population groups and country of origin for which different measures were designed, making it possible to see how far culturally specific issues affect the content of measures in this domain.
 
The questions asked by this study are exploratory and descriptive and so the importance of pre-registration is in achieving clear criteria for how each question is addressed, rather than evidential criteria for hypothesis-testing.
 
The authors responded comprehensively to three reviewer reports. This study will provide a wealth of useful information for those studying social connection, and should serve to make the literature in this field more psychometrically robust and less fragmented.

Revisiting the Effects of Helper Intention on Gratitude and Indebtedness: Replication and extensions Registered Report of Tsang (2006)

Grateful or indebted? Revisiting the role of helper intention in gratitude and indebtedness

Recommended by based on reviews by Jo-Ann Tsang, Sarahanne Miranda Field and Cong Peng
When receiving a favour, we may feel grateful and/or indebted to those who have helped us. What factors determine how much gratitude and indebtedness people experience? In a seminal paper, Tsang (2006) found that people reported feeling more gratitude when the helper's intention was benevolent (e.g., helping others out of genuine concerns for other people) compared to when the helper's intention was perceived to be selfish (e.g., helping others for selfish reasons). In contrast, indebtedness was not influenced by perceived helper intention. This finding highlighted the different processes underlying gratitude and indebtedness, and also inspired later work on how these two emotions may have different downstream influences, for instance on interpersonal relationships.

So far, there has been no published direct replication of this seminal work by Tsang (2006). In the current study, Chan et al. (2024) propose to revisit the effects of helper intention on gratitude and indebtedness, by replicating and extending the original studies (Study 2 & 3) by Tsang (2006). Participants will be asked to either recall (Study 2) or read (Study 3) a scenario in which another person helped them with either benevolent or selfish intentions, and rate how much gratitude and indebtedness they would experience in such situations. The authors predict that in line with the original findings, gratitude will be more influenced by helper intention than indebtedness. To further extend the original findings, the authors will also assess people's perceived expectations for reciprocity, and their intention to reciprocate. These extensions will shed further light on how helper intention may influence beneficiaries’ experiences of gratitude and indebtedness, and their subsequent tendencies to reciprocate.

The Efficacy of Attentional Bias Modification for Anxiety: A Registered Replication

Examining attentional retraining of threat as an intervention in pathological worry

Recommended by ORCID_LOGO based on reviews by Thomas Gladwin, Jakob Fink-Lamotte and 1 anonymous reviewer
Cognitive models ascribe a pivotal role to cognitive biases in the development and maintenance of mental disorders. For instance, attentional biases that prioritize the processing of threat-related stimuli have been suggested to be causally involved in the development and maintenance of anxiety disorders, including generalized anxiety disorder (GAD), which is marked by pathological worry. Therefore, these biases have garnered significant interest as potential diagnostic indicator and as targets for modification.
 
The idea that attention bias modification (ABM) can serve as a therapeutic intervention for GAD and other disorders was fueled by a seminal study by Hazen et al. (2009). In this study, 23 individuals experiencing high levels of worry underwent a computerized attentional retraining of threat stimuli (ARTS) or placebo control training during five training sessions. Relative to control, attention retraining was found to reduce preferential attention to threat, as well as depression and anxiety symptoms. However, as Pond et al. (2024) highlight in their review of the literature, the evidence endorsing the efficacy of ABM in alleviating anxiety disorders is still inconclusive. Moreover, some researchers contend that early positive findings might have been inflated due to demand effects.
 
Based on these considerations, Pond et al. (2024) propose a direct replication of Hazen et al. (2009) by subjecting a high-worry sample to five sessions of ARTS or placebo control. Departing from the frequentist analyses used in the original study, the authors will employ Bayesian analyses that allow more nuanced interpretation of the results, allowing consideration of evidence in support of the null hypothesis. The sampling plan will adhere to a Bayesian stopping rule, whereby the maximal sample size will be set at n=200. Furthermore, the authors extend the original study by addressing potential demand effects. For this purpose, they include a measure of phenomenological control (i.e., the ability to generate experiences align with the expectancies of a given situation) and evaluate its potential moderating impact on the attention bias training.

Neurophysiological correlates of plasticity induced by paired associative stimulation (PAS) targeting the motor cortex: a TMS-EEG registered report

Can TMS-evoked potentials act as biomarkers of long-term potentiation or long-term depression induced by paired associative stimulation?

Recommended by ORCID_LOGO based on reviews by Domenica Veniero, Lindsay Oberman and 1 anonymous reviewer
What are the neurophysiological correlates of paired associative stimulation (PAS) in inducing plastic changes in human motor cortex (M1)? Here, Arrigoni and colleagues (2024) will apply transcranial magnetic stimulation (TMS) to left M1 paired with electrical stimulation of the right median nerve at an ISI of 25 ms or 10 ms to induce long-term potentiation (LTP) or long-term depression (LTD), respectively. Arrigoni and colleagues (2024) will determine if these stimulation pairings effect cortical excitability using motor-evoked potentials (MEPs) and TMS-evoked potentials (TEPs). Specifically, they hypothesize PASLTP will increase the peak-to-peak amplitude of MEPs, whereas PASLTD will decrease the amplitude, replicating previous work. They will then extend these previous findings by examining TEPs. The authors anticipate modulation of the P30 and P60, which are TEPs thought to reflect local cortical excitability. They plan to account for the MEP reafference which may also mediate the P60 amplitude by stimulating at sub- and supra- motor threshold. Further, they hypothesize an increase of the N100, a marker of inhibitory processing mediated by GABA, by PASLTD. Finally, the authors will also examine the impact of cortical excitability over time to determine the duration of the PAS effects.   
 
This detailed examination of TEPs following PAS stimulation will determine which TEPs could be used as biomarkers with the induction of LTP and LTD through stimulation. The authors have built in an MEP replication for the PAS stimulation, supporting previous literature and acting as a positive control.

An #EEGManyLabs study to test the role of the alpha phase on visual perception (a replication and new evidence)

Understanding the relationship between alpha oscillations and visual perception

Recommended by ORCID_LOGO based on reviews by Chris Allen, Luca Ronconi and Alexander Jones
For nearly a century, rhythmic patterns in electrical brain activity have been of major interest in neuroscience and electrophysiology, but much remains to be discovered about their causal contribution to cognition and behaviour. Low-frequency oscillations in the alpha band (~8-13 Hz) have been suggested to facilitate the organisation and delivery of visual information to higher-level systems, including those involved in perception and decision-making. If so, visual perception should also operate in cycles that are synchronous with – and determined by – the phase of ongoing low-frequency oscillatory activity.
 
In this #EEGManyLabs study, Ruzzoli et al. (2023) propose a large-scale, multi-lab investigation (9 labs; N=315 human participants) of the relationship between the phase of alpha oscillations and visual perception. The authors focus in particular on replicating a formative study by Mathewson et al. (2009) which reported that during high-amplitude alpha fluctuations, stimulus visibility depended on the time the stimulus was presented relative to the phase of the pre-stimulus alpha activity. In addition, the amplitude of visual evoked potentials recorded with EEG was larger when the target was presented at peaks in pre-stimulus alpha. To explain their findings, Mathewson proposed an influential pulsed inhibition hypothesis in which low alpha power boosts both cortical excitability and stimulus processing (and hence perception), while high alpha power makes stimulus processing dependent on the phase during the alpha cycle at which the stimulus is presented.
 
In the first of (up to) two studies, the authors will seek to directly replicate the key finding of Mathewson et al: that when alpha power is high, the oscillatory phase determines perceptual performance and event-related electrophysiological correlates in a masked visual detection task. Specifically, (a) alpha oscillations are predicted to modulate the probability of perceiving a target stimulus within a single oscillatory cycle, with detection rate associated with separated (and potentially opposite) phase angles, and (b) alpha phase at the onset of the stimulus should drive electrophysiological correlates of stimulus processing (including the amplitude and/or latency of the N1 ERP component).
 
Provided the results of this first study do not conclusively disconfirm these hypotheses, the authors will then conduct a follow-up study in which the temporal predictability of the target onset (in relation to a fixation stimulus) is reduced to test the more severe hypothesis that the observed correlations between alpha phase and perception are linked directly to ongoing oscillations, independent of temporal expectations.

Is conscious perception necessary to direct attention? A replication of Jiang et al. (2006)

Can sexually salient stimuli direct attention outside of conscious awareness?

Recommended by ORCID_LOGO based on reviews by Myron Tsikandilakis and Surya Gayet
Are attention and consciousness inherently intertwined or distinct aspects of cognition? One report (Jiang et al. 2006) presented clear results in evidence of the latter. In this earlier study, the authors used a continuous flash suppression (CFS) paradigm which presents a colorful pattern to the dominant eye and stimuli of interest to the non-dominant eye; the colorful pattern masks the relevant stimulus from awareness. On each trial, the authors presented a sexually stimulating image and a scrambled image on different sides of a computer screen during CFS. They found that, even though participants were not consciously aware of the images, intact images that matched participants' sexual orientation could still capture attention.
 
Despite these seemingly clear results, the authors of the current Stage 1 manuscript pointed out that CFS studies are often not replicated, and the paper by Jiang et al. (2006) is no exception. Therefore, Chen et al. (2023) seek to replicate this study using a Bayesian (rather than NHST) analytic approach. This method will allow the authors to determine the strength of evidence for their hypotheses.
 
In this Stage 1 manuscript, Chen et al. present an introduction that motivates the replication, and a pilot study that replicated the procedure of Jiang et al. (2006) conducted with 21 participants. This led to a well-motivated statistical sampling plan and some small design changes for the main experiment, such as adding a staircasing procedure to remove potential performance ceiling effects, and using less extreme wording for stimulus attractiveness ratings. A clear study design template is presented, detailing the different hypotheses that will be tested, and what different outcomes would indicate.

Investigating individual differences in linguistic statistical learning and their relation to rhythmic and cognitive abilities: A speech segmentation experiment with online neural tracking

Individual differences in linguistic statistical learning and the relationship to rhythm perception

Recommended by ORCID_LOGO based on reviews by 2 anonymous reviewers
Previous research has demonstrated that experimental participants – both adults and infants – can track syllable co-occurrences in an artificial speech stream. This statistical learning (SL) is thought to support word segmentation and to be a core component of language acquisition. There is also some evidence that SL, as measured through artificial language tasks, is related to individual differences in language learning. What is not well understood is the underpinnings of individual differences in SL. In the current study, van der Wulp et al. (2023) will investigate the relationship between auditory SL and musical – specifically rhythmic – abilities. This work takes advantage of recent methodological innovations which allow online assessment of SL via electroencephalography (EEG) measures of neural entrainment. Up to N=105 participants will be recruited (using a well specified optional stopping procedure) and will be exposed to an artificial language using this EEG method to measure their response to the language through the exposure phase. In addition, post-tests will assess participants’ learning of the artificial language using behavioural tasks, as well as their abilities in a battery of tasks measuring rhythmic, musical, and cognitive abilities, and their vocabulary size. Core analyses will investigate whether the neural signature of statistical learning is found at a group level (i.e. replicating previous work) and whether at the individual level this is related to rhythm perception. Bayes factors will be used to assess the extent of evidence for these hypothesized relationships over the null. Exploratory analyses will explore other relationships, including with working memory and vocabulary size. 
 
The topic of individual differences in language learning and is important, but work in this area is often underpowered, and the correlational nature of the research makes it vulnerable to HARKing. In this context, the current RR looks set to make an important contribution. The Stage 1 manuscript was evaluated over two rounds of in-depth review by the recommender and two expert reviewers, and one additional round of review by the recommender, before issuing in-principle acceptance.

The world is seemingly awash with conspiracy theories – from well-trodden examples such as fake Moon landings, the 9/11 truth movement, and Holocaust denial, to relative newcomers including COVID as a bioweapon, QAnon, and the belief that the science of climate change has been invented or falsified. While there is a public perception that conspiracy theories are becoming more prevalent, recent evidence suggests that the rate of conspiracism is relatively stable over time (Uscinski et al., 2022). At any point in history, it seems that a certain proportion of people find themselves vulnerable to conspiracy beliefs, but what distinguishes those who do from those who don’t, and what are the causal factors?
 
In the current study, Liekefett et al. (2023) investigated the critical role of rumination – a perseverative and repetitive focus on negative content leading to emotional distress. In particular, the authors asked whether one component of rumination referred to as brooding (dwelling on one’s worries and distressing emotions) has a specific causal role in the formation of conspiracy beliefs. In a series of preliminary experiments, the authors first established a procedure for successfully inducing rumination, identifying various boundary conditions and requirements for a successful design. In the main study (N=1,638 to 2,007 depending on the analysis), they asked whether the induction of brooding causes a significant increase in conspiracy beliefs. Manipulation checks were also included to confirm intervention fidelity (independently of this hypothesis), and exploratory analyses tested the effect of various moderators, as well as the causal role of a complementary manipulation of reflection – a component of rumination in which attention is focused on the issue at hand rather than one’s emotions.
 
As expected by the authors' preliminary work, manipulation checks independently confirmed the effectiveness of the brooding intervention. In answer to the main research question, participants who brooded over the worries and negative emotions associated with an issue were more susceptible to conspiracy beliefs compared to a control group. However, while this effect of brooding was statistically significant, the confidence interval of the effect size estimate overlapped with the authors' proposed smallest effect size of interest (d = 0.20), suggesting that the practical value of the effect remains to be determined.
 
Overall the findings are consistent with a range of psychological theories suggesting that rumination induces negative affect and/or narrows attention to negative information, which in turn may make conspiracy theories seem more probable and render individuals more vulnerable to cognitive bias. The authors note the importance of future work to define the smallest effect of practical significance, analagous to the criteria used to determine the 'minimal clinically important difference’ in medical research.
