Electronic sports (esports), the competitive play of video games, has seen a large surge in popularity over the past few decades. Millions of people nowadays participate in esports as a hobby, and many consider becoming professional esports athletes as a potential career path. However, psychological factors that may predict one's long-term success in esports have remained unclear.

In the current study, Martončik and colleagues (2023) propose to examine potential predictors of long-term esports success, in three currently most impactful PC esports games, namely League of Legends, Counter Strike: Global Offensive, and Fortnite. Based on an extensive review of the literature and four pilot studies, the authors will examine to what extent naive practice and deliberate practice, as well as other psychological factors such as attention, speed of decision-making, reaction time, teamwork, intelligence and persistence, can predictor player's highest rank in the past 12 months, as an indicator of long-term success. Deliberate practice has been proposed to play an essential role in the development of expertise in other domains, and the current study offers a test of the role of both naive and deliberate practice in long-term esports success. The novel measurement on naive and deliberate practice, developed as part of the current investigation, will also be a valuable contribution to future research on esports. Lastly, from an applied perspective, the results of the current study will be of great interest to individuals who are considering pursuing a professional career in esports, as well as professional and semi-professional esports teams and coaches.

The Temporal Doppler Effect refers to the subjective perception that the past is further away than the future even when both temporal distances are objectively the same from the present moment (Caruso et al., 2013). In the current study, Zhang et al. ran a replication of this phenomenon and tested one possible explanation for it, namely that people overestimate the temporal distance of the past because the past is filled with more events than the future. This is because we can access information only about planned events for the future, but have access to both planned and unplanned events that happened in the past (filled-duration illusion; Thomas & Brown, 1974).

 

Over two studies, the authors found that the sampled participants reported feeling that the past was psychologically closer than the future, which is the opposite of what has previously been reported and termed the Temporal Doppler Effect (Caruso et al., 2013). In addition, the authors reported inconsistent results regarding the correlations between the psychological distance and different variables associated with the filling rate of duration. The authors discuss the differences between their own results and those by Caruso et al. (2013) in terms of methodological and contextual differences and highlight cultural aspects that may be critical to consider in future replications and overall testing of this phenomenon. As such, they highlight that, at the moment, the Temporal Doppler Effect should not be considered a robust and culturally universal phenomenon.

Single gene alterations have been estimated to account for nearly half of neurodevelopmental conditions (NDCs), providing a crucial opportunity for animal models to understand the underlying mechanisms, causes and potential treatments. The use of systematic reviews (SRs) can, in principle, provide a powerful means to synthesise this evidence-base; however, the reporting quality of previous SRs in preclinical animal research has been found lacking (Hunniford et al., 2021). In the current study, Wilson et al. (2023) will undertake an umbrella review – a systematic review of systematic reviews – to assess the characteristics and reporting quality of SRs that, in turn, synthesise research in genetically-modified animals to model NDCs. In particular, the authors will extract key features of reviews (including, among others, the aim and primary research questions, relevant animal model, and number of studies in the SR), in addition to quality indicators such as risk of bias and completeness of reporting. In doing so, the authors aim to enhance guidance on the conduct and reporting of systematic reviews in this area.

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.

Cerebral small vessel disease (CSVD) is a common and multi-faceted set of pathologies that affect the small arteries, arterioles, venules and capillaries of the brain. The disease manifests through a range of symptoms and conditions, including psychiatric disorders, abnormal gait, and urinary incontinence, while accounting for 25% of strokes and nearly 50% of dementia.

 

The presence of CSVD is associated with white matter lesions (WML) detected using neuroimaging, which have in turn been shown to predict future stroke, cognitive decline and dementia. While vascular risk factors of CSVD (such as hypertension and obesity) are also associated with CSVD, a complete picture of the predictive relationship between WML, cognitive decline, and blood pressure remains to be determined, as does the role of sex/gender. These inter-relationships are important to determine for improving the diagnosis and treatment of CSVD.

 

In the current study, Beyer et al. will analyse a large emerging dataset from the LIFE-Adult project – a longitudinal, two-wave, population-based study – to ask whether higher blood pressure predicts a greater increase in WML, and whether progression of WML is associated with measures of memory and executive function. In addition, the authors will explore the relationship between abdominal obesity and WML progression, and the extent to which WML progression, and its interaction with vascular risk factors, depends on sex/gender.
