Rhythmic changes in pain can lead to corresponding modulations of EEG amplitudes in theta, alpha, and beta bands. But the question remains open as to whether these modulations are actually tracking pain, or maybe rather saliency or stimulus intensity. The question is of some importance because a marker of pain per se could be useful for tracking felt pain without a verbal response, and could be useful in investigating interventions for treating pain (such as suggestion).  Here, Leu et al. (2023) will address the question of whether modulations reflect saliency or else the intensity of pain, by using an oddball paradigm in which most trials are a pain stimulus of a certain intensity, and oddball trials will sometimes occur, at either a higher intensity or a lower intensity than the baseline ones. If the modulations reflect salience, the modulation at the frequency of the oddball will be similar for high and low intensity oddballs. However, if the modulations reflect pain intensity, the modulations for the low rather than high oddball condition will be lower.

For centuries, the relationship between creativity and mental health has been a subject of fascination, propelled by the impression that many of the most famous artists in history likely suffered from mood disorders or other mental illnesses. However, with the advent of psychological science – including more precise and diagnostic clinical measures – the empirical evidence for an association between creativity and depressive symptoms has been mixed, with some studies suggesting a positive relationship and others showing either no effect or indicating that the link, if there is one, may be driven by other personality characteristics (Verhaeghen et al., 2005).

 

In the current study, Lam and Saunders will use an online design in 200 participants to ask whether creativity is associated with higher depressive traits, and further, whether that relationship depends on two additional variables that could explain an observed positive correlation: self-reflective rumination (repetitive thoughts that maintain a negative mood state) and the frequency with which individuals engage in reappraisal (a regulation strategy that involves reinterpreting an event or situation to diminish its negative impact). If justified by the main confirmatory findings, the authors will also explore the moderating role of gender and how any observed associations are reflected in more fine-grained measures of creativity. The results promise to shed light on not only the basic question of whether creativity is related to depressive traits, but the extent to which that association depends on related determinants of mental health.

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.

Research in clinical psychology has found that interpretation bias (perceiving ambiguous information in a systematically negative or hostile way) and repetitive negative thinking (recurrent, prolonged worry or rumination) are associated with a range of psychopathologies – including depression, anxiety and paranoia – but the complex interplay between them in driving symptomatology is unclear. Here, Chung and Cheung (2022) propose a longitudinal examination of the directional relationship between interpretation bias and psychological symptoms in subclinical depression and paranoia, as well as the potential transdiagnostic mediating role of repetitive negative thinking. Using an online three-wave design, they ask whether the association between negative interpretation biases and psychological symptoms is bidirectional, whether negative interpretation biases are associated with repetitive negative thinking over time, and whether repetitive negative thinking is associated with psychological symptoms over time. They will also test whether negative interpretation biases and psychological symptoms exert reciprocal influences across dimensions through repetitive negative thinking, and whether repetitive negative thinking acts as a transdiagnostic mediator for depression and paranoid thoughts. Overall, the study aims to generate a clearer understanding of the relationship between interpretation biases and subclinical symptomatology, as well as clarifying the role of rumination as a transdiagnostic mechanism that mediates psychopathology.

For centuries, the ubiquity of language and music across human societies has prompted scholars to speculate about their cross-cultural origins as well as their shared and unique characteristics. Depending on the extent to which contemporary theories emphasise the role of biology vs. culture, a range of hypotheses have been proposed concerning expected similarities and differences in song and speech. One class of hypotheses stemming from cultural relativism assumes a lack of universal regularities in song and speech, and therefore predicts no systematic cross-cultural relationships. On the other hand, more recent evolutionary hypotheses such as the social bonding hypothesis, motor constraint hypothesis, and sexual selection hypothesis all predict differences or similarities in specific characteristic of vocalisations, such as pitch regularity, pitch interval size, and melodic contour. Existing results are mixed in their support of these predictions.

 

In the current study, Ozaki et al. (2022) embark on an ambitious project to elucidate cross-cultural similarities and differences between speech and song in 81 different linguistic varieties spanning 23 language families. Understanding precisely how song and speech are related is methodologically challenging due to the multitude of confounds that can arise in comparing natural recordings. Here the authors overcome these difficulties with four types of carefully controlled recordings: singing, recitation of sung lyrics, spoken description of the song, and instrumental version of the sung melody. The authors will then examine six features that are amenable to reliable comparison, including pitch height, temporal rate, pitch stability, timbral brightness, pitch interval size, and pitch declination. With this data in hand, the authors will ask which acoustic features differ reliably between song and speech across cultures, with the expectation that song will exhibit higher pitch, slower rate and more stable pitch than speech. At the same time, the authors expect song and speech to be reliably similar in the characteristics of timbral brightness, pitch intervals and pitch contours. In addition to these confirmatory tests, the authors will explore variation across a range of additional stimulus characteristics and ancillary research questions.
