Ageing is associated with exaggerated overstaying in foraging behaviour.
Article in npj aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
People constantly decide how much time to invest in rewarding activities. Foraging tasks assess this decision-making by measuring when individuals switch between contexts. People typically perform suboptimally in these tasks, largely due to overstaying, but it remains unclear whether this tendency changes with age independently of cognitive abilities and mental health factors. Previous research showing increased sensitivity to the opportunity cost of time in older adults predicts less overstaying, whereas a hypothesised shift towards exploitative behaviour predicts more overstaying. In an online foraging task, 350 young and older adults decided when to switch between contexts with varying reward conditions. We also assessed cognitive performance and self-reported motivation and depression. Participants consistently overstayed, and this behaviour was strongly associated with sensitivity to reward changes. Despite this, older adults selectively overstayed more without increased reward-based adaptation. Our findings show ageing is associated with exaggerated overstaying, supporting increased exploitative behaviour in old age.
