Hyperphantasia is an abundance of mental imagery, the opposite of aphantasia. Images can feel vivid and lifelike, sometimes seeming to overlay real vision (projectors) rather than staying purely mental (associators).
Zhong and colleagues · Neuropsychologia
Researchers analyzed free-text comments from 25 autistic and 25 non-autistic adults with aphantasia, matched for age, who answered one open-ended question at the end of an online survey. Comments fell under imagery, thinking, and emotions and social life; more non-autistic people mentioned imagery in other senses, mostly describing it as intact, while more autistic people described themselves as thinking in words. Many described memories as known facts rather than relived scenes, and some described knowing an emotion without feeling it. The group differences rest on small numbers and a single question.

In one school, 13.8% of 94 fourth graders scored in the aphantasia range and 27.7% in the hyperphantasia range, both above adult estimates. The authors suggest teachers offer strategies that do not rely on picturing.
Takahashi, Omura and Sugimura · Neuropsychologia
Older adults reported more vivid visual and multisensory imagery, while aphantasia was more prevalent in younger groups. This suggests that age should be considered when identifying aphantasia and setting diagnostic thresholds.
Monzel and colleagues · Consciousness and Cognition
VVIQ items showed high redundancy for identifying aphantasia, with inter-item correlations ranging from .79 to .90. A single screening question about visualizing a familiar place achieved high specificity (98.8%) and sensitivity (97.5%) against the strictest definition of core aphantasia (VVIQ = 16), suggesting the full 16-item questionnaire is unnecessary for screening purposes.
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.
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.

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.
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.
McVay and Mooring · Biochemistry and Molecular Biology Education
In interviews with ten biochemistry students and two instructors at one US university, students mostly described visualization as drawn structures, pathways and reaction mechanisms, while instructors meant picturing molecules in the mind. Two students said they had aphantasia and described workarounds, such as reasoning in words or writing out memorized structures just before exams; one reported no improvement in picturing but had not tried any exercises. The authors suggest instructors teach several ways to do visual tasks and be clearer about the representations they use and why they matter.
Schwarzkopf and colleagues · Royal Society Open Science
Vividness ratings robustly capture a wide range of subjective experiences, from internal mental depictions to externally projected imagery. This suggests aphantasia should be redefined to distinguish between faint imagery and a total lack of pictorial representation.
Taylor and colleagues · Scientific Reports
Researchers found no meaningful association between mental imagery vividness and sensory sensitivity, despite both correlating with autistic traits. This suggests that imagery and sensory processing may not share a common neural mechanism.
Sabel and colleagues · Psychological Reports
Researchers compared hoarding symptoms in 58 people with aphantasia and 23 with unusually vivid imagery against matched typical imagers, allowing for age and depression. People with aphantasia reported no more hoarding symptoms than their matches, though they leaned more on objects as memory aids. People with very vivid imagery reported fewer hoarding symptoms and were less likely to live in cluttered homes. From this comparison of existing groups, the authors suggest that vivid imagery may protect against hoarding.
Lebron Flores and Moacdieh · International Journal of Design Creativity and Innovation
Students shown an AI-generated website before designing their own rated the experience lower, and for them imagery vividness did not predict how they felt about it. The authors say AI inspiration should be used with caution.
Kvamme and colleagues · Neuropsychologia
Among people with aphantasia, those with more (though still weak) imagery reported more alexithymia and anxiety, the reverse of typical imagers. The authors suggest faint imagery may prompt emotional processing that fails.
Kvamme and colleagues · Heliyon
In 591 young adults, more vivid imagery went with an inward-focused style: attention to body signals, mindfulness, and openness. In statistical models, imagery related to mental health only through this style, partly through lower alexithymia.
Yavuz and Nazir · Language, Cognition and Neuroscience
In 158 English-speaking adults, how vividly people said they could picture things was not linked to the size of their vocabulary overall. Word by word, people with more vivid imagery did slightly worse on the most concrete words, such as tweezers or octopus, and in an exploratory comparison the 24 people with the weakest imagery scored higher than the 24 with the most vivid, about 82 against 76 out of 100. The authors suggest people with weak imagery may lean on word-based definitions, and call the findings provisional until they are repeated.
Chen and colleagues · Empirical Studies of the Arts
In a preregistered study, 45 Chinese university students viewed paintings in a virtual reality museum, sometimes told to imagine being inside each painting with as many senses as possible and sometimes told simply to appreciate them without imagining. Imagining with several senses made paintings feel more vivid, more arousing and more appealing, and students with stronger imagery across the senses rated paintings as more vivid and appealing overall. Vividness statistically accounted for both links with appeal, and arousal also did for the instruction. The authors suggest multisensory imagery practice could become part of art education.
Pepin and colleagues · Consciousness and Cognition
Involuntary mental imagery is more frequent and vivid than hallucinations, though both share similar phenomenological traits. This suggests these inner experiences exist on a continuum rather than being entirely distinct phenomena.
Scholz and Scholz · International Mad Studies Journal
Researchers found that biomedical and cognitive studies often frame aphantasia as a disorder or deficit, ignoring the lived experiences of aphantasics. This highlights the need for more inclusive research that avoids pathologizing neurodiversity.
Wymark and colleagues · Journal of the Neurological Sciences
In this conference abstract, people with aphantasia, average imagers and very vivid imagers did a task that tests whether imagining something gets in the way of seeing it. The more vivid a group's imagery, the more imagining hurt accuracy, by about 9 percent in the vivid group, while the aphantasia group was slightly more accurate on imagery trials. Brain recordings also differed between the groups. The authors argue aphantasia is a different way of processing rather than a deficit, but the abstract does not say how many people took part.
