Esto ayuda a entender por qué las comparaciones con imágenes de cuerpos recientes pueden distorsionar la autopercepción.

This serial dependence is often treated as one bias, but it can constitute opposing influences: an attractive pull toward recent input and a repulsive push away from it. These have been linked to different stages, decisional and perceptual, but separated only for simple visual features. We asked whether the same separation holds for a socially significant category, the human body. Observers categorised images of male bodies as low or high on body fat and muscularity (binary choice, N = 74); a trial-level analysis estimated the perceptual and decisional contribution to each judgment. For body fat, the perceptual contribution was","pubDate":"2026-10-21","url":"https://www.biorxiv.org/content/10.64898/2026.10.15.756928v1?rss=1"},"indexado":"2026-10-21T22:39:37.287Z"}}
