Walking through doorways causes forgetting: environmental integration.

Area of Science:

• Cognitive Psychology
• Human Memory
• Event Cognition

Background:

• Object memory declines after relocation, a phenomenon known as the location updating effect.
• Previous research has debated whether this effect stems from event model updating or task demands.
• The degree of information integration with the environment has been a key factor in understanding this memory decline.

Purpose of the Study:

• To investigate the role of information integration and probe type in the location updating effect.
• To differentiate between event model updating and task demands as causes for memory impairment after relocation.
• To test the hypothesis that well-integrated information is more susceptible to location updating effects.

Main Methods:

• Experiment 1 used visual probes instead of verbal labels to minimize item-probe mismatch.
• Experiment 2 introduced less integrated information (word pairs) to assess the necessity of high integration for the effect.
• Both experiments involved participants moving between locations and subsequent memory probes for objects.

Main Results:

• Location updating effects were observed in both experiments, irrespective of probe type or information integration level.
• Memory for objects was impaired after relocation, confirming the location updating effect.
• The findings held true even when memory probes were visual or when less integrated information was presented.

Conclusions:

• The location updating effect is robust and occurs even with visual probes or less integrated information.
• These results support the event cognition view, suggesting that mental updating of dynamic events disrupts memory.
• The findings indicate that the process of updating one's representation of a dynamic environment impacts object memory recall.
