      abstract     = {Encoding the position of another person in space is vital
                      for everyday life. Nevertheless, little is known about the
                      specific navigational strategies associated with encoding
                      the position of another person in the wider spatial
                      environment. We asked two groups of participants to learn
                      the location of a target (person or object) during active
                      navigation, while optic flow information, a landmark, or
                      both optic flow information and a landmark were available in
                      a virtual environment. Whereas optic flow information is
                      used for body-based encoding, such as the simulation of
                      motor movements, landmarks are used to form an abstract,
                      disembodied representation of the environment. During
                      testing, we passively moved participants through virtual
                      space, and compared their abilities to correctly decide
                      whether the non-visible target was before or behind them.
                      Using psychometric functions and the Bayes Theorem, we show
                      that both groups assigned similar weights to body-based and
                      environment-based cues in the condition, where both cue
                      types were available. However, the group who was provided
                      with a person as target showed generally reduced position
                      errors compared to the group who was provided with an object
                      as target. We replicated this effect in a second study with
                      novel participants. This indicates a social advantage in
                      spatial encoding, with facilitated processing of both
                      body-based and environment-based cues during spatial
                      navigation when the position of a person is encoded. This
                      may underlie our critical ability to make accurate distance
                      judgments during social interactions, for example, during
                      fight or flight responses.},
