We've all experienced it: you get up to grab something from another room, but once you arrive, you stand there puzzled, unable to recall why you went there in the first place. 

This common occurrence can be both amusing and frustrating. But, there's a scientific explanation behind this phenomenon. It's known as the "doorway effect," and understanding it can shed light on how our memory functions in everyday situations.

The doorway effect 

The "doorway effect" refers to the tendency to forget what we intended to do after passing through a doorway into a new room. Researchers have found that moving through doorways serves as an "event boundary" in our minds, separating episodes of activity and thereby compartmentalising them. 

This means that when you move from one room to another, your brain updates its understanding of the current situation, making it more challenging to retrieve memories formed in a different context.

How our memory works

Our memory is organised into distinct events or episodes. When we enter a new environment, our brain takes in new information and sensory inputs, creating a new "episode." This process helps us manage and organise memories efficiently. However, it can also lead to moments where previously active thoughts or intentions become less accessible after transitioning into a new space.

Factors that influence forgetfulness

Several factors can increase the likelihood of experiencing the doorway effect:

Coping strategies

While the doorway effect is a natural part of how our memory functions, there are ways to mitigate its impact:

Minimise distractions: Focus on the task at hand and try to limit multitasking, especially when transitioning between spaces.
