Route selection in non-Euclidean virtual environments

Area of Science:

• Cognitive Psychology
• Spatial Navigation
• Human Spatial Representation

Background:

• Route selection in unfamiliar environments offers insights into cognitive spatial representations.
• Investigating how environmental manipulations affect navigational performance reveals underlying spatial processing mechanisms.

Purpose of the Study:

• To explore the nature of spatial representations used in navigation.
• To determine how physically impossible environments influence route choice and spatial memory.

Main Methods:

• Participants navigated virtual mazes to targets, with mazes being either physically realizable or impossible (containing 'wormholes').
• Route choices at junctions were recorded and analyzed based on shortest-distance predictions and past success rates.

Main Results:

• Participants successfully found shortest routes in both realizable and impossible mazes.
• In impossible mazes, junction choices were more influenced by past success than shortest distance.
• In realizable mazes, shortest distance primarily determined junction choices.

Conclusions:

• Navigational choices are guided by a graph-like spatial representation incorporating distance and past success.
• Maze complexity influences the weighting of distance versus past success in decision-making during navigation.
