The authors introduce a deep learning framework to reproduce sequences of response times and use it to provide evidence for a stability–flexibility trade-off underlying task-switching costs.

Lockdowns may help control disease, but also come with potential costs. Domestic violence complaints in India increased in districts with the strictest lockdown rules, and remained higher 1 year later, even after restrictions were loosened.

Using longitudinal and repeated cross-sectional data, Danielsen et al. find no indication that the proportion of Danish young adults with self-injury, suicidality or eating disorder symptoms increased during lockdown.

In Iran, women and men protest day and night for women, life and liberty. The moment has come for the international academic community to take action to remove the obstacles faced by Iran’s scholarly community, and join the call for equality, democracy and human rights.

Using publication and editorial team composition records from more than 1,000 journals, Liu and coauthors uncover pervasive gender inequalities among academic editors. Only 8% of editors-in-chief are women. Nearly 6% of editors publish one-third of all their papers in the journal they edit, and this self-publication pattern is stronger among men editors.

Qasim et al. examine how emotion affects memory using direct brain recording and deep brain stimulation.

A mapping between emotions and speech prosody is commonly assumed. This study shows, using Bayesian modelling, that differences across individuals, cultures and sexes contribute more to the model prediction than a shared global mapping.

Using functional magnetic resonance imaging, Setti et al. show that the superior temporal cortex is synchronized across auditory and visual presentation of the same narrative, even in sensory-deprived individuals who lack any audiovisual experience.

A campaign-level field experiment shows how digital advertising may have affected differential turnout in the 2020 US presidential election, particularly among early voters.

The authors use morphometric and brain lesion data to identify a convergent brain network shared by psychiatric disorders.

Registration has been proposed as a possible solution to the reproducibility crisis in scientific research. In its more than 20 years of practice in biomedical research, registration has been valuable — but it is still largely limited to clinical trials, and its implementation is still largely inconsistent.

Standard decision models assume that all options' values are encoded on a common scale by a unique representation system. Across nine experiments, Garcia et al. provide evidence that challenges this assumption: participants treat experiential and symbolic options asymmetrically.

‘Vocal bursts’ such as sighs, shrieks and shouts are human emotional vocalizations. In this study, Brooks et al. reveal similarities and differences in the emotional meaning of vocal bursts across five cultures.

Although we have been able to track how cultural innovations spread among farming populations in prehistoric Europe, we know relatively little about this among European hunter-gatherers. Dolbunova et al. use a range of techniques to shed light on how the making and use of pottery spread among early-to-mid-Holocene hunter-gatherers west of the Urals.

Analysis of pottery made and used by hunter-gatherers in northeastern Europe in the sixth millennium bc supports the existence of super-regional networks enabling cultural transmission long before the arrival of farming.

Yu et al. examine whether cooking is associated with all-cause and cardiopulmonary mortality. They find that lower mortality risks are associated with cooking with clean fuels, and this may be partly attributed to increased household physical activity.

In 11,407 children, Baldwin et al. report gene–environment correlations between polygenic scores for psychiatric disorders and adverse childhood experiences, as well as partial genetic confounding of associations between adverse childhood experiences and mental health.

US universities have made public commitments to recruit and retain faculty of colour. Analysis of three federal datasets shows that at current rates diversity in US faculty will never reach racial parity. Yet, colleges and universities could achieve parity by 2050 by diversifying their faculty at 3.5 times the current pace.

Kristal et al. find that rewriting a résumé so that previously held jobs are listed with the number of years worked (instead of employment dates) increases callbacks from real employers compared to résumés without employment gaps by approximately 8%.

Based on her own experience, Gabrielle Wong-Parodi describes how a community-engaged approach has the potential to strengthen research and increase its impact.
