| 7pczt_v2 | Repulsive and attractive serial dependence: Balancing sensitivity and stability in visual perception | The human visual system recruits adaptation mechanisms that enhance perceptual sensitivity over time. However, such mechanisms can also introduce substantial perceptual biases, disrupting stable perceptual experiences. Research on serial dependence has suggested that the visual system promotes stability by mechanisms that integrate new sensory inputs with inputs obtained in the recent past. Yet, it remains unclear when and how such mechanisms operate. The present study tested the hypothesis that adaptation produces a repulsive bias during earlier processing, which is later mitigated by post-perceptual decision processes at the time of report. In two orientation perception tasks, observers used a mouse to reproduce the orientation of a briefly presented target. We recorded the mouse trajectory to track the temporal dynamics of their reproduction responses. We found that the mouse reports began more slowly when the current stimulus was similar to the prior stimulus. In the mouse-tracking data, the initial phase of the response exhibited a strong repulsive bias away from the prior stimulus, but this bias diminished significantly as the response unfolded, ending with either weaker repulsion or small attraction depending on task contexts. These findings provide strong evidence that prior stimuli induce an early repulsive bias, which is then mitigated through post-perceptual decision processes during the response. This suggests that the visual system balances the competing demands of sensitivity and stability by reducing early repulsive biases through higher-order decision mechanisms, optimizing behavior in a given task context. | 2025-05-10T23:47:24.918085 | 2025-05-10T23:52:57.867274 | 2025-05-10T23:48:07.057135 | psyarxiv | 1 | pending | 2 | 1 | https://doi.org/10.31234/osf.io/7pczt_v2 | CC0 1.0 Universal | [] | Kuo-Wei Chen; Gi-Yeul Bae | [{"id": "4qvmf", "name": "Kuo-Wei Chen", "index": 0, "orcid": null, "bibliographic": true}, {"id": "py9s3", "name": "Gi-Yeul Bae", "index": 1, "orcid": null, "bibliographic": true}] | Kuo-Wei Chen | Social and Behavioral Sciences; Perception; Cognitive Psychology; Memory; Vision | [{"id": "5b4e7425c6983001430b6c1e", "text": "Social and Behavioral Sciences"}, {"id": "5b4e7427c6983001430b6c71", "text": "Perception"}, {"id": "5b4e7427c6983001430b6c8c", "text": "Cognitive Psychology"}, {"id": "5b4e7427c6983001430b6ca5", "text": "Memory"}, {"id": "5b4e7428c6983001430b6cc0", "text": "Vision"}] | https://osf.io/download/681fe5ae3858410fe1ce9ecd | 0 | no | no | [] | 2025-05-11T00:11:37.463510 |
