This paper introduces DataDIVER, an automated method for discovering computational models from data, which reveals novel insights into human and animal learning.

Task-space dimensions guide human exploration in complex environments

The paper shows humans use a structured exploration strategy in complex environments by systematically sampling task dimensions, improving learning efficiency.

Rearing condition affects behavioral response to cross-modal expectancy violation paradigm in zebra finches

This study shows that rearing conditions in zebra finches affect their behavioral response to audiovisual stimuli, indicating that early sensory experience influences multisensory integration during mate recognition.

Social control, not service quality, explains fast growth in the cleaner wrasse Labroides dimidiatus.

The study shows that fast growth in cleaner wrasse is linked to reduced social control rather than service quality, with slow growers spending more time near dominants.

Acute Stress in Female Adolescent Rats Increases Anxiety-like but not Depression-like Behaviors

This study shows that acute stress in female adolescent rats increases anxiety-like behaviors but not depression-like behaviors, regardless of the timing of stress exposure.

Stochastic choice drives variability in patch foraging decisions in humans and rats

This study shows stochastic choice explains variability in patch foraging decisions in humans and rats, making leaving variability independent of environmental rewards and using suboptimal internal reward rate estimates.

Zebrafish facility report on implementation of artificial plants as structural enrichment

Across six zebrafish lines over one year, artificial home-tank plants left sex ratio, fertility and microbial counts unchanged, while fish avoided plant areas.

Global meta-analysis reveals urban-associated behavioral differences among wild populations

This study performs a global meta-analysis of urban-associated behavioral differences across species, finding increased boldness, aggression, exploration, and activity in urban populations.
