However, an understanding of how temporal stimuli are processed remains incomplete. Few studies have explored pause duration in temporal reproduction tasks, revealing two critical stages of timing perception: the transition zone and the plateau. The transition zone, occurring for approximately 3 seconds after stimulus presentation, involves continuous updates in reproduced duration and shows the processing of the temporal stimulus. The plateau, occurring before the response, is about the storing and preparation for duration reproduction. In the behavioral experiments here, it was found that the transition zone is modality-independent and goes up to 2-3 seconds. Since the visual modality was implemented, the spatial characteristics of the visual field were also investigated. It was shown that the eccentricity of visual stimuli affects the reproduced duration. Spatial manipulation, like cueing, affected both effects: transition zone and eccentricity effect. An fMRI study investigated the processing of temporal stimuli in reproduction task, examining neural activation during the transition zone and plateau stages. These findings indicate that the transition zone activates the posterior insula, caudate, and putamen, and the plateau stage shows activation in the frontal medial cortex. A resting-state study addressed the individual differences in participants’ responses. This study provides new insights into the neural mechanisms underlying time perception and the factors influencing it.系所名稱：心智意識與腦科學研究博士學位學程thesis
