“The neuroscientists at Johns Hopkins started at the most basic level they could think of – the ‘Who painted this?’ test, which she pretty much failed. Her semantic memory about art and artists, her primary area of expertise, was significantly impaired. Remarkably, though, when the scientists included some of her own artworks in the testing, she correctly flagged every one as hers. Even more surprising, when the researchers added drawings done in a style somewhat similar to Johnson’s, she picked them out as artworks she might have produced. To do so, she had to be drawing on some sort of memory.”
