Using inertial information alone to estimate linear self-displacement with varying durations of constant velocity

During self-motion in the absence of vision and proprioception, inertial information can be used to compare different magnitudes of linear self-displacement. However, during periods of constant velocity, no inertial information is available, thus, how perceived displacement is evaluated during different durations of constant velocity is unknown. Here, participants judged which of two inertially experienced distances was longer. Three durations of constant velocity (1, 3, 5s) were included in order to evaluate whether estimates of distance would vary as a function of constant velocity duration. The results are described using a biologically plausible neuronal model which accounts for both duration and peak velocity.
The talk is open to the public. Guests are cordially invited!
