Walking reduces the gap between encoding and sensorimotor alignment effects in spatial updating of described...

Area of Science:

• Cognitive Psychology
• Neuroscience
• Spatial Cognition

Background:

• Spatial updating is crucial for maintaining self-to-object relationships during movement.
• Prior research indicated physical movement aids spatial updating in real environments but not described ones.
• Previous studies primarily focused on rotation, neglecting other movements like walking.

Purpose of the Study:

• To investigate the impact of walking on spatial updating within described environments.
• To compare the effects of imagined rotation, physical rotation, and walking on spatial updating.
• To determine if walking offers unique benefits for spatial updating in virtual or described settings.

Main Methods:

• Utilized the judgement of relative directions task to assess spatial updating.
• Compared conditions involving imagined rotation, physical rotation, and walking.
• Evaluated accuracy, response times, and calculated encoding and sensorimotor alignment effects.

Main Results:

• Response times revealed differences in alignment effects between movement types.
• In imagined and physical rotation, the encoding alignment effect exceeded the sensorimotor alignment effect.
• This gap in alignment effects disappeared during the walking condition.

Conclusions:

• Walking appears to uniquely enhance spatial updating in described environments.
• The findings suggest walking strengthens the connection between allocentric and sensorimotor representations.
• This enhancement is likely due to the richer sensory information acquired during locomotion.
