Varieties of Aphantasia

Introducing the term aphantasia was very helpful in raising awareness of interpersonal variations in the vividness of mental imagery. But taking aphantasia to be a monolithic category can do more harm than good. Any suggestion of the solution to or the explanation of aphantasia will only muddy the waters, as it will lump together very different underlying conditions. It is time to start talking about different types of aphantasia and draw the consequences for experimental methodology.
