Imagine walking through a door and forgetting everything. It’s possible, and a new study in The Quarterly Journal of Experimental Psychology explains how. Abstract, you have the floor.

Previous research using virtual environments has revealed a location-updating effect in which there is a decline in memory when people move from one location to another. Here we assess whether this effect reflects the influence of the experienced context, in terms of the degree of immersion of a person in an environment, as suggested by some work in spatial cognition, or by a shift in context. In Experiment 1, the degree of immersion was reduced by using smaller displays. In comparison, in Experiment 2 an actual, rather than a virtual, environment was used, to maximize immersion. Location-updating effects were observed under both of these conditions. In Experiment 3, the original encoding context was reinstated by having a person return to the original room in which objects were first encoded. However, inconsistent with an encoding specificity account, memory did not improve by reinstating this context. Finally, we did a further analysis of the results of this and previous experiments to assess the differential influence of foregrounding and retrieval interference. Overall, these data are interpreted in terms of the event horizon model of event cognition and memory.

Still with me? Basically, what the researchers found is that new memory episodes (event models) form in our brains whenever we enter a new environment. As you move from place to place, you’re stacking memories on top of memories, making them harder to retrieve.

I imagine this knowledge could affect how educators, event planners, or anyone involved in learning and group collaboration structure their operations. If you know that moving people from room to room causes them to forget, wouldn’t it be better to keep everyone in one room all day? If that’s not technically feasible, then what can you do design-wise to mitigate the forgetting?
