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 using binocular-rivalry (BR)- removing the need for memory or 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.

Lives without imagery – Congenital aphantasia

Neurologist Adam Zeman of the University of Exeter publishes study involving a patient, known as MX, who reported losing his ability to visualize in the mind. Zeman refers to the inability to generate mental imagery as aphantasia.

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.

Loss of imagery phenomenology: a case of ‘blind imagination’

Patient MX reports losing the ability to generate visual images. MX experienced almost no imagery on standard questionnaires, yet performed normally on standard tests of perception, visual imagery and visual memory. These unexpected findings were explored using fMRI scanning.

Conflicting intuitions may be based on differing abilities

From early imagery interviews of Francis Galton through many modern surveys, a consistent diversity of self-reports on one’s own mental imagery abilities suggests that some 2-5% of people are very poor- or non-visual- imagers. Comparable estimates have been made in auditory and other imagery modalities.
