Two studies investigated updating of self-position and heading during real, imagined, and
simulated locomotion. Subjects were exposed to a two-segment path with a turn between …

Participants attempted to return to the origin of travel after following an outbound path by
locomotion on foot (Experiments 1–3) or in a virtual visual environment (Experiment 4) …

People can update their spatial relationships relative to the environment while walking
without vision. The hypothesis that such updating is automatic was tested in a locomotor task …

As people move through an environment, they typically change both their heading and their
location relative to the surrounds. During such changes, people update their changing …

Three experiments investigated spatial orientation in a virtual navigation task. Subjects had
to adjust a homing vector indicating their end position relative to the origin of the path. It was …

Four experiments investigated the nature of spatial representations used in locomotion.
Participants learned the layout of several objects and then pointed to the objects while …

Blindfolded adult participants (7 male and 9 female) were asked to point to previously seen
targets after a body rotation. In 1 condition, participants had to update their positions relative …

A series of experiments examined the role of the motor system in imagined movement,
finding a strong relationship between imagined walking performance and the biomechanical …

Previous studies have generally considered heading perception to be a visual task.
However, since judgments of heading direction are required only during self-motion, there …

THE control of head direction in humans walking along planned circular trajectories was
investigated in this study. Five healthy volunteers were asked to walk at a constant speed …
