Although the physical office may be identical, other features vary--e.g., time of day, light conditions, one's internal state--leading to differing degrees of similarity, even among putatively identical contexts. Alternatively, contexts can change abruptly, such as leaving the office to go home for dinner. Despite the prevalence of various levels of contextual overlap in everyday life, prior experimental work has largely ignored their influence on related experiences. To address this gap, we took a novel approach in which participants viewed real-world audiovisual stimuli (comme","pubDate":"2026-10-24","url":"https://www.biorxiv.org/content/10.64898/2026.10.19.760268v1?rss=1"},"indexado":"2026-10-24T15:21:10.758Z"}}
