Spatial updating of environments described in texts

Area of Science:

• Cognitive Psychology
• Spatial Cognition
• Human Movement Science

Background:

• Egocentric spatial updating is crucial for navigation and interaction with the environment.
• Previous research often involved visually perceived scenes, limiting understanding of updating with linguistically encoded information.
• The role of physical movement versus imagined movement in egocentric updating remains debated.

Purpose of the Study:

• To investigate egocentric spatial updating using linguistically encoded scenes.
• To determine the conditions under which effortless, on-line egocentric updating occurs.
• To differentiate the effects of physical movement and imagined movement on spatial updating.

Main Methods:

• Participants encoded spatial scenes linguistically.
• Experiments involved physical and imagined rotations.
• Object locations were sometimes anchored in mental frameworks or described with spatial labels.
• Sensorimotor encoding was manipulated.

Main Results:

• Egocentric updating occurred deliberately and backwardly with linguistically anchored scenes, irrespective of rotation mode.
• Removing spatial labels did not alter results during imagined rotations.
• Physical rotations, unlike imagined ones, facilitated on-line updating when scenes used sensorimotor encoding.

Conclusions:

• Effortless, on-line egocentric updating is dependent on physical movement.
• Sensorimotor encoding of spatial scenes is a prerequisite for effortless egocentric updating.
• Linguistic encoding and imagined movement alone are insufficient for on-line egocentric updating.
