Though researchers working on congenital aphantasia (henceforth “aphantasia”) agree that this condition involves an impairment in the ability to voluntarily generate visual imagery, disagreement looms large as to which other impairments are exhibited by aphantasic subjects. This article offers the first extensive review of studies on aphantasia, and proposes that aphantasic subjects exhibit a cluster of impairments. It puts forward a novel cognitive theory of aphantasia, building on the constructive episodic simulation hypothesis of memory and imagination. It argues that aphantasia (...) is best explained as a malfunction of processes in the episodic system, and is therefore an episodic system condition. (shrink)

This chapter focuses on the role of the imagination in creativity, using aphantasia as a case study. It first distinguishes between imagination and mental imagery, before giving an overview of what we know about aphantasia to date, focusing in particular on findings pertaining to creativity, imagination, and memory. It then turns to the role of the imagination in creativity, agreeing with philosophers that the imagination plays an essential role in creativity, which allows individuals to imagine a multitude of possibilities. This (...) view is then supplemented with a theory of the neuro-cognitive underpinnings of the imagination, whereby both the imagination and memory are supported by the same neural network – the default mode network. Finally, the chapter argues that this fuller picture allows us to understand the creative abilities of people with aphantasia, thoroughly resisting the thought that they might generally be unimaginative or uncreative.
