Quantifying aphantasia through drawing: Those without visual imagery show deficits in object but not spatial memory
This large-scale online study of aphantasics revealed a dissociation in object and spatial content in their memory representations and provides evidence for separate systems in memory that support object versus spatial information.
What is the Link Between Mental Imagery and Sensory Sensitivity? Insights from Aphantasia
- Psychology, Environmental SciencePerception
It is suggested for the very first time that sensory imagery and sensory sensitivity are related, and that aphantasics are characterised by both lower imagery, and lower sensitivity.

Phantasia - the psychological significance of lifelong visual imagery vividness extremes
Visual imagery typically enables us to see absent items in the mind’s eye. It plays a role in memory, day-dreaming and creativity. Since coining the terms aphantasia and hyperphantasia to describe…

The human imagination: the cognitive neuroscience of visual mental imagery
- Psychology, BiologyNature Reviews Neuroscience
Recent insights into the neural mechanisms that underlie visual imagery are discussed, how imagery can be objectively and reliably measured, and how it affects general cognition are discussed.
Memory deficits in aphantasics are not restricted to autobiographical memory - Perspectives from the Dual Coding Approach.
- Psychology, BiologyJournal of neuropsychology
Evidence was obtained for the influence of visual imagery on all memory components beyond autobiographical memory as well as verbal short-term and long-term memory in congenital aphantasics and demographically matched controls.

Previously overlooked neuropsychological evidence on the relation between imagery and perception is reviewed, and its relative immunity to the foregoing alternative explanations is discussed.
Training Visual Imagery: Improvements of Metacognition, but not Imagery Strength
- PsychologyFront. Psychology
Trial-by-trial ratings of vividness gained predictive power on subsequent rivalry dominance as a function of training, suggesting that, while imagery strength might be immune to training in the current context, people’s metacognitive understanding of mental imagery can improve with practice.
Functional Anatomy of High-Resolution Visual Mental Imagery
- Psychology, BiologyJournal of Cognitive Neuroscience
There is strong evidence that imagery based on verbal descriptions can recruit regions known to be engaged in high-order visual processing and region activation in other regions was very similar in the two conditions.

Smaller Primary Visual Cortex Is Associated with Stronger, but Less Precise Mental Imagery.
- Psychology, BiologyCerebral cortex
A behavioral paradigm that measures the functional impact of a mental image on subsequent conscious perception and related these measures to the anatomy of the early visual cortex estimated by fMRI retinotopic mapping observed a negative relationship between primary visual cortex (V1) surface area and sensory imagery strength, but found positive relationships between V1 and imagery precision.
The functional effects of color perception and color imagery.
- Psychology, BiologyJournal of vision
It is demonstrated that imagery of pure colors without form structure can influence subsequent color perception and can be localized in retinotopic space.
The sensory strength of voluntary visual imagery predicts visual working memory capacity.
- Psychology, BiologyJournal of vision
The results suggest that luminance was disrupting sensory mechanisms common to both visual working memory and imagery, and not a general working memory system, and the disruptive selectivity of background luminance suggests that good imagers, unlike moderate or poor imager, may use imagery as a mnemonic strategy to perform the visual workingMemory task.
