Knight, Milton and Zeman · Neuropsychologia
Aphantasics showed normal visual working memory performance and decodable neural representations in the visual cortex. This suggests aphantasia is a lack of conscious awareness rather than an inability to generate or store visual information.
Sulfaro · Psychonomic Bulletin & Review
Researchers discovered that aphantasia and vividness judgements are compromised by poorly defined references for typical imagery. This indicates that current measures like the VVIQ may be invalid and misleading.
Panigutti and colleagues · Neuroscience & Biobehavioral Reviews
This systematic review found only 11 studies on imagery and hallucinations in Parkinson's, Alzheimer's and schizophrenia, and none in Lewy body dementia. Seven reported a link and four did not, so the evidence is indecisive.
Lambert and colleagues · Neuropsychologia
Researchers found that anauralia and aphantasia share a 0.8% prevalence but have distinct psychological profiles. This suggests that the absence of sensory imagery is modality-specific rather than a single, unified condition.
Fleming and Dijkstra · Cell Research
Researchers discovered that mental imagery reactivates the same sensory code as perception at the single-neuron level. This suggests that aphantasia may stem from how this shared activity is generated, modulated, or read out by the brain.
Ernst, Kronbichler and Meyer · Scientific Reports
Researchers found that imagining a moral dilemma from a third-person perspective is linked to higher acceptability of harmful actions. This suggests visual perspective, not just vividness, helps shape how we make moral decisions.
Calzavarini · Synthese
Researchers found that brain areas process mental imagery using modality-invariant properties rather than sensory-specific divisions. This suggests mental imagery and aphantasia are best understood through a supramodal framework.
Bartolomeo · Annual Review of Vision Science
Congenital aphantasia likely stems from impaired access to intact visual representations rather than a total lack of mental content. This suggests conscious visualization is an emergent property of large-scale network coordination.
Delhaye and colleagues · Consciousness and Cognition
People with aphantasia remembered which color went with which shape as well as typical imagers, even for hard-to-name shapes. The authors conclude that neither imagery nor verbal labels is necessary for this kind of memory.
New and colleagues · Cortex
Aphantasia is linked to higher rates of neurodevelopmental, neurological, and psychiatric disorders compared to typical imagery. This highlights the need for multisensory evaluations and tailored interventions for neurodiverse profiles.
Yan, Roberts and Bainbridge · Neuropsychologia
Aphantasic individuals showed a robust picture superiority effect and recalled symbols better than pictures. This challenges dual-coding theory by demonstrating that visual imagery is not essential for the memory advantages of image-based stimuli.
Li and colleagues · Neuropsychologia
In a phone navigation game, 63 people with aphantasia were slower than others on complex levels, with no clear gap on simple ones, and rated their own sense of direction lower. The authors suggest picturing a map helps most when there is a lot to remember.
Scholz and colleagues · Neuropsychologia
Researchers found that aphantasics activate sensory precursors that lack the perceptual geometry of true imagery. This suggests aphantasia is a failure of multi-stage integration rather than just a lack of neural reactivation.
Martin and colleagues · Learning and Individual Differences
Among 1,451 high school students, weaker imagery went with lower science scores, a gap that was smaller where students said teachers reduced mental load. The authors suggest such teaching may help weak imagers, but the data cannot show cause.
Moskoff · University of Colorado Honors Journal
People with aphantasia responded faster than controls on language tasks, with neither group showing expected switching costs. This suggests that mental imagery is not required for language comprehension and may even slow processing.
Koenig-Robert, Pace and Pearson · Psychological Review
Researchers propose that imagery reshapes spontaneous neural activity via inhibitory feedback rather than driving new spikes in early visual areas. This suggests the spectrum from aphantasia to hyperphantasia is driven by the strength of cortical inhibition.
Monzel and colleagues · Cortex
People with aphantasia recalled fewer letters than others from a grid flashed for 50 milliseconds, but not from one shown for 5 seconds. This suggests imagery helps hold a split-second visual trace, while other strategies work given more time.
Duckett and Simons · Neuropsychologia
In 60 adults, neither questionnaire imagery scores nor average vividness predicted memory for scenes, but memories rated more vivid than a person's own average were more often correct. Re-analyzed aphantasia data showed the same trial-level link.
Le Clézio and colleagues · Neuropsychologia
Aphantasics did not show a visual impedance effect during reasoning, unlike typical imagers who were slowed by irrelevant visual details. This suggests that mental imagery can sometimes hinder cognitive performance by creating interference.
McVay and Mooring · Biochemistry and Molecular Biology Education
Biochemistry students with aphantasia often hold fixed mindset beliefs, while instructors prioritize internal mental imagery. This highlights the need for teaching methods that accommodate diverse cognitive profiles.
