When and how is duration encoded in the brain? In this EEG study, we investigated the cognitive and neural correlates of environmental constraints and production of durations. Previous works revealed that participants over-produce durations when immersed in larger virtual environments, relative to smaller ones (e.g., Delong et al., 1981; Ma et al., 2024; Riemer et al., 2018). A proposed explanation for these findings, derived from the action constraint theory, which suggests that larger environments involve longer possible movements (and consequently, more time). However, this working hypothesis remains untested, and the underlying cognitive and neural mechanisms unknown. To test this , we manipulated environmental constraints in virtual reality (i.e., room size, ceiling height) and combined behavioral measures of duration production (relative production time and error) with EEG recordings and multivariate pattern analyses (decoding). Behavioral results replicate and extend previous ones: participants produced longer durations in large environments, relative to smaller ones. Decoding analyses showed that it is possible to decode both the produced duration and the size of the environment, as early as the first button press. These results suggest that the effect of environmental constraints occurs at the early stages of duration production. This study provides a deeper understanding of how environmental constraints influence temporal cognition.
