Quantifying aphantasia through drawing

Online study of aphantasics (n=63) and controls required participants to draw real-world scenes from memory. Study found those without visual imagery show deficits in object but not spatial memory.

Tom Ebeyer doesn’t have a mind’s eye, and for the first 20 years of his life he didn’t even know that others did! This radio documentary explores the beginning discovery of aphanatsia through Tom’s journey, and the weaving connection to Professor Adam Zeman, who coined the word.

Could you have this memory disorder?

Susie McKinnon can’t picture images and has very few memories from her life. McKinnon has aphantasia and Severely Deficient Autobiographical Memory or SDAM for short. Early findings suggest possible correlations between conditions.

The perceptual and phenomenal capacity of mental imagery

Mental imagery is a fundamental part of human cognition that bridges cognition with sensory representations. This paper introduces a novel technique to measure the sensory capacity of mental imagery while removing the need for memory and any direct subjective reports.

Visual working memory performance in aphantasia

Visual working memory performance is assessed in aphantasic individual. Study finds while participant performs significantly worse than controls on the most difficult visual working memory trials, surprisingly, their performance on a task designed to involve mental imagery did not differ from controls.

Mental imagery and visual working memory

Performance in visual working memory can be predicted by the strength of mental imagery as assessed with binocular rivalry. Findings could help reconcile current controversy regarding the mechanism and location of visual mnemonic storage.
