Description
Substantial evidence supports a causal influence of bodily signals on the experience of time. Here, a series of studies will be presented investigating how interoceptive and sensorimotor processing affect time perception from the range of seconds to the long-term representation of memories across time. First, evidence will be discussed supporting a dynamic perspective on mechanisms involved in processing multiple-second durations, showing that individual differences in interoceptive processing predict timing abilities specifically when the external context is not informative on elapsed time. Data from neuroimaging and neuropsychological studies show that this relation is supported by specific brain correlates, involving the insular cortex and its connectivity with a sensorimotor network responsible for the integration of interoceptive and exteroceptive information. Further evidence suggests that interactions between sensorimotor regions and the medial temporal lobes also support the retrieval of temporal information from memory. Finally, recent findings from a task-based fMRI study will be presented, showing that memories for one's own life events, but not general semantic memories, are organized according to a sagittal mental timeline, supporting a crucial role of sensorimotor experience related to walking and running in the development of the temporal organization of autobiographical memories. Overall, these findings shed light on how different dimensions of temporal experience are rooted in bodily states, and highlight the need to investigate further how information afforded from interoceptive and exteroceptive channels interact in building our representation of time.
