How do young children determine location? Evidence from disorientation tasks

Area of Science:

• Developmental psychology
• Cognitive science
• Spatial cognition

Background:

• Children's ability to reorient themselves in space after disorientation is crucial for navigation.
• Previous research indicates children use geometric cues from enclosed spaces to reorient.
• Established disorientation methods involve viewer rotation with eyes closed.

Purpose of the Study:

• To investigate spatial coding in 18- to 25-month-old children using two novel disorientation tasks.
• To compare children's performance in viewer-rotation versus space-rotation tasks.
• To determine the influence of testing location (inside vs. outside the space) on spatial coding.

Main Methods:

• Two disorientation tasks were employed: viewer rotation and space rotation, with visually untrackable movements.
• Children were tested inside and outside an isosceles triangular space with one unique and two equivalent corners.
• Object location memory was assessed in different corners following disorientation.

Main Results:

• Children performed above chance in the viewer-rotation task irrespective of the object's location.
• In the space-rotation task, performance was above chance only at the unique corner.
• Spatial coding accuracy was higher when children were tested from inside the space compared to outside.

Conclusions:

• Toddlers' spatial coding abilities differ depending on the type of disorientation experienced.
• Geometric spatial coding in young children is influenced by egocentric versus allocentric reference frames.
• Environmental context (e.g., being inside or outside a space) significantly impacts spatial memory retrieval in toddlers.
