What is it about?

This paper is about how simple exposure to a stimulus can impede your ability to learn about it later. It uses a new method that eliminates many concerns about whether experiments with humans and animals are investigating the same phenomenon when they examine this kind of question.

Why is it important?

The work helps to differentiate theories of attention and "interference" with respect to how exposure to a stimulus can affect later learning. It also introduces a method of study that does not depend on instructions that orient participants to the task or generates similar specific expectations across participants, which makes it more analogous to animal research in that respect.


This article should help people to understand that complexity exists in even simple things, like simply encountering a new stimulus. That complexity is revealed when trying to understand how the phenomenon works, and how to effectively study it while ruling out other explanations.
