In today's episode, we look at the neurological condition known as 'aphantasia'- the inability to conjure mental images. For the vast majority of the human population, picturing an image in mind is just a normal thing. So normal in fact that it probably hasn't even occurred that there are those of us who are, by and large, cognitively blind. The surprising reality is that many people who are cognitively blind, or aphantasic, don't even know it themselves.
We rarely question how our 'internal' experience may differ from other people. We may have asked ourselves questions like whether we see the same colours as each other or know that words might have different meanings to different people, but rarely do we consider how varied our ability to visually imagine might be. For some people, imagining something does not include an internal visual image, which means they are aphantasic, and this can have striking implications on many of their cognitive functions, such as memory and learning.
Aphantasia has only recently begun to receive attention in the fields of research, even though it has been known about for over a century. But what does it mean if you are cognitively blind? Well, a lot really. It may affect a number of things, but that doesn't normally equate to being a problem, for those who are, have usually found various alternative strategies to manage. More often than not, these alternatives aren't even recognised as alternatives, but rather just the way they've always been. Take memorising directions, for example- where one person might picture the directions, someone with aphantasia might memorise the street names or rely on GPS. Aphantasia changes the way we think, learn and create and all this we explore in today's episode.
