Décima, Agustín PatricioBarraza, José FernandoLópez-Moliner, Joan2025-01-272025-01-272022-020042-6989https://hdl.handle.net/2445/218003In this article we present a temporal extension of the slow motion prior model to generate predictions regarding the temporal evolution of the contrast induced speed bias. We further tested these predictions using a novel experimental paradigm that allows us to measure the dynamic perceptual difference between stimuli through a series of manual pursuit open loop tasks. Results show good agreement with our model’s predictions. The main findings reveal that hand speed dynamics are affected by stimulus contrast in a way that is consistent with a dynamic model of motion perception that assumes a slow motion prior. The proposed model also confirms observations made in previous studies that suggest that motion bias persisted even at high contrast as a consequence of the dynamics of the slow motion prior.10 p.application/pdfengcc-by-nc-nd (c) Elsevier Ltd, 2022http://creativecommons.org/licenses/by-nc-nd/4.0/PercepcióVelocitatMovimentPerceptionSpeedMotioninfo:eu-repo/semantics/article7308942025-01-27info:eu-repo/semantics/openAccess
