“…Intriguingly, these studies tend to position these task-irrelevant inducers close in time to the target (e.g., within a second in Togoli et al, 2021), which could promote potential perceptual integration. Well-documented phenomena, like ensemble perception (Whitney and Yamanashi Leib 2018), show a tendency to attract individual items toward the ensemble mean (Nakajima et al 1992;Zhu et al 2021;Baykan, Zhu, Allenmark, et al 2023;Baykan, Zhu, Zinchenko, et al 2023). A classic manifestation of this is the time-shrinking illusion, where successive intervals seem to blend into one another (Nakajima et al 1992;Burr et al 2009).…”

Our perception and decision-making are susceptible to prior context, as seen in sequential dependence where our judgment of stimulus magnitude is biased toward what we experienced in previous trials. While sequential bias in the spatial domain has been extensively studied, less is known about it for time perception. Furthermore, it is still debatable whether sequential bias arises during perceptual or post-perceptual stages. To investigate this, we conducted functional magnetic resonance imaging (fMRI) on twenty-one participants performing a timing task, which involved two phases - duration encoding and duration reproduction. Participants had to remember the duration of the green coherent motion and wait for a cue to reproduce the perceived duration. The cue could be either Go or No-go. For the No-go cue, participants should only passively view the display. We observed that the reproduction error was positively correlated with the prior duration only when the preceding task was also active reproduction. In contrast, encoding the prior duration without reproduction was insufficient to induce sequential bias. Neurally, we observed activated timing-related networks, such as striato-thalamo-cortical circuits, and performance monitoring networks when the trial sequence implicitly predicted a Go trial. When action required a post cue, the right frontal gyrus, associated with response inhibition, became activated. Importantly, the hippocampus showed sensitivity to sequential bias and its activation was negatively correlated with the individuals sequential bias following active reproduction trials. These findings highlight the crucial role of striato-thalamo-cortical networks in time perception, as well as memory networks in sequential biases at the post-perceptual stage.

Our perception and decision-making are susceptible to prior context. Such sequential dependence has been extensively studied in the visual domain, but less is known about its impact on time perception. Moreover, there are ongoing debates about whether these sequential biases occur at the perceptual stage or during subsequent post-perceptual processing. Using functional magnetic resonance imaging, we investigated neural mechanisms underlying temporal sequential dependence and the role of action in time judgments across trials. Participants performed a timing task where they had to remember the duration of green coherent motion and were cued to either actively reproduce its duration or simply view it passively. We found that sequential biases in time perception were only evident when the preceding task involved active duration reproduction. Merely encoding a prior duration without reproduction failed to induce such biases. Neurally, we observed activation in networks associated with timing, such as striato-thalamo-cortical circuits, and performance monitoring networks, particularly when a “Response” trial was anticipated. Importantly, the hippocampus showed sensitivity to these sequential biases, and its activation negatively correlated with the individual’s sequential bias following active reproduction trials. These findings highlight the significant role of memory networks in shaping time-related sequential biases at the post-perceptual stages.
