The presence of mahi-mahi at multi-predator feeding aggregations modifies striped marlin attack behaviour

Abstract Terrestrial multi-species predator feeding aggregations (MPFAs) are characterized by contest competition, but scramble competition is likely more common at MPFAs in pelagic waters. However, empirical investigations are rare. Aerial video was used to estimate abundances o...

Do Children Who Develop Faster Go on to Age Faster in Midlife?

We quantified the association between rate of child development and pace of midlife aging in the Dunedin Study and the Add Health Study. Physical development was quantified in Dunedin participants ( N = 1,037; age 45) using a composite comprised of (1) birth weight for gestationa...

Towards responsible AI in workplace-based assessment: a scoping review using Downing’s framework

This scoping review maps generative AI applications in workplace-based assessment (WBA) and analyzes validity evidence through Downing’s framework. Following JBI methodology and PRISMA-ScR guidelines, four databases were searched (2022-February 2026) with dual-AI screening and hu...

SEMi-Complete by Design: A Monte Carlo simulation to assess Measurement Invariance in Moderated Nonlinear Factor Analysis and SEM-Trees

Ensuring the validity of psychological assessments is crucial, yet differential itemfunctioning (DIF) can threaten measurement invariance (MI) (Bauer, Belzak, and Cole2020). Recent calls for improved DIF detection methods emphasize the need for moreadvanced statistical approaches...

Human and chimpanzee leaders are more risk-loving

Leadership and risk-taking are often assumed to be interrelated, but this assumption has rarely been investigated empirically in humans or other species. Analyzing data from the German Socio-Economic Panel (SOEP) and observer reports from two African chimpanzee sanctuaries, this...

Social information quality and environmental volatility shape collective foraging behaviour

Abstract Collective foraging is widespread across the animal kingdom, allowing animals to more effectively discover resources. However, collective foragers need to balance a key trade-off between private exploration and using social information. Social information can come in ver...

Leveraging large language models to map triggers of contamination-related obsessive-compulsive symptoms

Abstract Recent advancements in natural language processing and large language models (LLMs) facilitate the study of under-researched areas in mental health. Their capacity to automatically and meaningfully analyze large-scale text data makes them particularly valuable for studyi...
