What is Aphantasia and Hyperphantasia?
Since 2015, aphantasia and hyperphantasia have reshaped our understanding of imagination, revealing that not everyone visualizes mentally the same way. These discoveries highlight the diverse nature of human imagination. Aphantasia is the inability to create mental images, while hyperphantasia is extremely vivid mental imagery
With the introduction of terms representing the absence and abundance of visual imagination, we’ve uncovered a wealth of new insights into the workings of the mind. Drawing from Adam Zeman’s latest Review in Trends in Cognitive Science, we’ve come so far, yet there’s still so much more to discover.
The following is a comprehensive overview of what we know and the unanswered questions about aphantasia and hyperphantasia after a decade of groundbreaking research.
Aphantasia: What We Know About the Absence of Visual Imagination
How common is aphantasia?
Approximately 1% of the population experiences aphantasia directly, with 2–6% having dim and vague imagery. This makes aphantasia more rare than hyperphantasia but still affects millions of people worldwide.
Historical background and recognition
- Ancient Origins: The foundation of our understanding of imagination can be traced back to ancient philosophers such as Aristotle, who posited that “the soul never thinks without a phantasma,” implying that imagery is essential to thought. This idea has profoundly influenced philosophical and psychological thinking for centuries.
- Historical Recognition: The concept of “non-visualizers,” as observed by Sir Francis Galton in the 19th century, remained largely unexplored until Zeman’s work catalyzed a resurgence of interest and research.
Types of aphantasia: Congenital vs. acquired
Aphantasia can be both congenital (present from birth) and acquired, where the ability to visualize mentally is lost due to neurological or psychiatric conditions. This distinction has helped identify key brain regions involved and raised questions about the mechanisms of acquiring and losing imagery abilities.
How is aphantasia diagnosed and measured?
Research now employs diverse methods—self-reported questionnaires, behavioral tasks, physiological responses, and neuroimaging—to uncover the complexities of mental imagery absence in aphantasia.
Does aphantasia affect all senses?
Beyond visual modality: While primarily recognized for its effect on visual imagination, some individuals with aphantasia are absent imagery across all senses, while others may experience selective imagery absence in imagining sounds (auditory), smells (olfactory), tastes (gustatory), tactile sensations (tactile), and even motor activities (motor imagination). This complex, nuanced spectrum suggests aphantasia’s broad sensory implications.
Is aphantasia genetic?
Familial patterns: Aphantasia’s occurrence in families suggests a possible genetic influence. “Our research into the neurological basis of aphantasia hints at a complex interplay between genetics, brain structure, and experience,” says Zeman.
Career tendencies and cognitive traits
Cognitive and occupational tendencies: Individuals with aphantasia may exhibit a tendency toward occupations in scientific and technical fields, possibly reflecting a different mode of problem-solving and creativity.
Can people with aphantasia dream visually?
Preservation of dream imagery: Many individuals with aphantasia report visual dreams despite a lack of voluntary imagery, indicating intact visual processing capabilities in different consciousness states.
What causes aphantasia in the brain?
Neurological underpinnings: Aphantasia’s experience is likely linked to specific disruptions in neural connectivity rather than merely diminished activity, highlighting significant roles for the connections between frontoparietal and visual networks. Notably, alterations in the connectivity of the ‘fusiform imagery node’ (FIN), which plays a crucial role in visual processing, could be a key factor contributing to the phenomenon.
How does aphantasia affect memory?
Autobiographical memory effects: Aphantasia leads to significantly reduced autobiographical memory, a reduction that is evident in both subjective reports and objective measures. This indicates a distinct impact on the ability to recall personal past events with vivid detail.
Face recognition challenges in aphantasia
Challenges in face recognition: Face recognition is notably more difficult for about 40% of those with aphantasia compared to those with typical or hyperphantasic imagery.
What cognitive abilities remain strong?
Intact spatial imagery: Spatial imagery abilities remain strong in aphantasia, showcasing a particular aptitude for spatial tasks.
Links to autism and personality traits
- Association with autistic traits: Higher autism spectrum quotient scores among those with aphantasia suggest an intricate link with autistic traits. However, the relationship between autism, known for its “thinking in pictures” trait in some cases, and imagery vividness remains complex and multifaceted.
- Introversion and aphantasia: A higher tendency towards introversion in aphantasia indicates a distinct personality trait pattern.
How does aphantasia affect planning and future thinking?
Future thinking: Aphantasia affects future event visualization, leading to less detailed and vivid imagined scenarios.
Mental health implications
Mental health and aphantasia: Aphantasia may protect against emotional disorders related to distressing imagery, suggesting a link between imagery vividness and certain mental health risks, such as PTSD.
Daily life adaptations
Impact on daily life: Despite the absence of visual imagination, individuals with aphantasia often develop highly effective strategies for navigating their lives, employing alternative sensory processing and memory techniques that prove just as effective as visual strategies.
“The discovery of aphantasia challenges our fundamental assumptions about how people think and remember, revealing that non-visual strategies for navigation and memory can be just as effective.“
Adam Zeman
Unanswered Questions About Aphantasia and The Image-Free Mind
Are there different types of aphantasia?
Subtypes and Individual Variance: The existence of aphantasia subtypes and the significant variation within suggest a complex spectrum that has yet to be fully explored. Further research is needed on how aphantasia impacts non-visual modalities such as auditory, olfactory, gustatory, tactile, and motor imagery.
What genes are involved in aphantasia?
The Genetic Code: While evidence suggests a genetic link, the specific genes and mechanisms involved in aphantasia remain unidentified.
How exactly does the aphantasic brain work?
Neural Mechanisms: More research is required to understand the precise neural differences and similarities between individuals with and without aphantasia across various types of imagery and cognitive tasks.
Full mental health picture
Impact on Mental Health: Although aphantasia may provide some protection against emotional disorders linked to distressing imagery, such as PTSD, its broader implications for mental health and well-being are still not well understood. Further studies are necessary to understand how the absence of mental imagery interacts with emotional processing and memory, potentially offering resilience against visually triggered emotional disorders.
The autism connection
Relationship with Autistic Traits: There is a noted higher occurrence of autistic traits among those with aphantasia; however, the exact nature of this relationship, especially in how it affects their processing and cognition, is still unclear. This complex relationship warrants deeper exploration.
Complete impact assessment
Full Spectrum of Impact: The nuanced ways in which aphantasia affects personal experiences, learning styles, and emotional processing require more detailed investigation.
Hyperphantasia: What We Know About the Abundance of Visual Imagination
How common is hyperphantasia?
Prevalence: Hyperphantasia is estimated to affect around 3% of the population, making it more common than aphantasia.
Does hyperphantasia affect all senses?
Enhanced multisensory imagery: Like aphantasia, hyperphantasia can extend beyond visual imagery to enrich the vividness of other sensory modalities. Individuals with hyperphantasia often experience an enhanced ability to vividly recreate and manipulate not just visual but also auditory, tactile, olfactory, gustatory, and motor sensations.
Career paths for people with hyperphantasia
Creative and occupational inclinations: Individuals with hyperphantasia often find themselves in creative professions, potentially benefiting from their enhanced ability to visualize and imagine.
Connection to synaesthesia
Synaesthesia: There’s an observed increased rate of synaesthesia among individuals with hyperphantasia, suggesting a link between the heightened vividness of mental imagery and the tendency to experience involuntary, secondary sensory experiences, such as seeing colors when hearing sounds.
Brain differences in hyperphantasia
Neural connectivity: Preliminary findings suggest differences in brain connectivity patterns in those with hyperphantasia. These differences in brain connectivity not only underscore the heightened sensory processing capabilities in hyperphantasia but also may explain the increased prevalence of synaesthesia in this group.
