Your Brain on Slideshows

Your Brain on Slideshows

Here’s what happens to audience brains when presenters speak while showing text-heavy slides. Their working memory gets overloaded.

Working memory is that part of the cognition system where we contemplate information, wrangle with it, try to digest it. But working memory has limits on its cognitive load. It can only handle so much (not much, as it turns out).

Want to see for yourself? Try this little game. While it isn’t the same as sitting in a text-heavy presentation, it recreates a similar environment where our brains are trying to keep track of too many things at once.

My best scores were better than the average – and that’s the danger. Some of us *think* we’re really good at multitasking when we really aren’t doing any of the tasks too well. Here a couple of strategies for reducing the cognitive overload that comes with text-heavy slides.

We’ll talk about this and more practical steps for improving slideshows in my webinar, Nontoxic Slideshows, this Friday at noon EDT.

@sara_mayo @guardian Mine were fake news about Hillary and that's definitely not due to my browsing habits.

@guardian great article with questionable ads.
