Spatial updating during locomotion is automatic. Even without vision, the brain automatically tracks position changes, though this can be overridden with deliberate thought.

Area of Science:

  • Cognitive Neuroscience
  • Human Locomotion
  • Spatial Navigation

Background:

  • Humans can maintain spatial awareness and update their position relative to the environment while walking, even without visual input.
  • The automaticity of this spatial updating process during locomotion has been a subject of investigation.

Purpose of the Study:

  • To test the hypothesis that spatial updating relative to the environment during walking is an automatic process.
  • To investigate whether this automatic updating can be suppressed or overridden by deliberate cognitive control.

Main Methods:

  • A locomotor task was designed where participants walked without vision to a target location via an intermediate point.
  • Two conditions were implemented: 'updating' (walking to the target's actual position) and 'ignoring' (imagining no movement from the start).

  • Response times and performance accuracy were measured under conditions of immediate versus delayed response initiation.

    • Main Results:

    • Participants performed significantly better in the 'updating' condition compared to the 'ignoring' condition when immediate responses were required.
    • The performance difference between the two conditions diminished when participants were given more time to respond.
    • This suggests an initial automatic spatial updating process that can be retrospectively modulated by conscious control.

    Conclusions:

    • Spatial updating during locomotion appears to be an automatic process that occurs without conscious effort.
    • With sufficient time, individuals can override this automatic updating using more deliberate cognitive processing.
    • The findings highlight the interplay between automatic and controlled processes in spatial navigation and environmental interaction.
