Biases in long-term location memory in the real world

Area of Science:

• Cognitive Psychology
• Spatial Cognition
• Environmental Psychology

Background:

• The category adjustment (CA) model explains distortions in human spatial memory.
• Previous CA research primarily used simplified, artificial laboratory environments.
• Limited research exists on CA in complex, navigable real-world settings.

Purpose of the Study:

• To extend the category adjustment (CA) approach to a real-world, navigable environment.
• To investigate if long-term location memory is retrievable despite recall inaccuracies.
• To compare memory performance in real-world versus laboratory settings.

Main Methods:

• Assessed memory for a fountain's location in a busy university campus square.
• Used photographic reproduction for recall testing.
• Employed a forced-choice recognition test to evaluate memory retrieval.
• Analyzed data based on the category adjustment model.

Main Results:

• Recall data exhibited the typical bias predicted by the CA model.
• Recognition data, however, showed performance at chance level.
• A discrepancy was observed between recall and recognition accuracy.

Conclusions:

• Results indicate potential differences in memory accessibility between lab and real-world environments.
• Long-term spatial memories in complex environments may be less accessible than previously assumed.
• The findings prompt re-evaluation of the CA model's application in naturalistic settings.
