I noticed, while playing with one of my kitties, that her irises would enlarge about a quarter-second before she strikes. I imagine maybe our eyes relax when we daydream or something. Didn't read the article, just seemed like a relevant observation.

This is the best summary I could come up with:

The pupils of our eyes get larger when we are focusing on a task–and the size may give clues about our working memory capabilities, a new study has found.

Moreover, they found that the more a person's eyes dilated when focusing on a task, the better they did on tests measuring their working memory.

They found that the pupils were more dilated in people who focused more intensely and consistently paid attention—and they performed better on the memory tasks.

"What we found was that the lowest performers on the tasks showed less pupil dilation," Robison said in a press statement.

"For the highest-performing participants, their pupil dilations were both larger overall and the individuals were more discerning about the information they were asked to recall."

"This is exciting research because it adds another valuable piece of the puzzle to our understanding of why working memory varies between individuals."
