Andrea Blomkvist (CPNSS) and David F. Marks (Arles, France) have published a new paper titled “Defining and ‘diagnosing’ aphantasia: Condition or individual difference?” in Cortex.

Research into the newly-coined ‘condition’ of ‘aphantasia’, an individual difference involving the self-reported absence of voluntary visual imagery, has taken off in recent years, and more and more people are ‘self-diagnosing’ as aphantasic. Yet, there is no consensus on whether aphantasia should really be described as a ‘condition’, and there is no battery of psychometric instruments to detect or ‘diagnose’ aphantasia. This paper explores fundamental and methodological problems affecting aphantasia research and diagnosing.
