Aphantasia, a term first coined in 2015, refers to the inability to voluntarily visualise mental images. While most people can conjure vivid pictures in their mind’s eye, those with aphantasia experience little to no mental imagery. A recent article published by the Aphantasia Network proposes an updated framework, expanding the scope beyond visual imagination to a multisensory phenomenon. This redefinition not only deepens scientific understanding but also introduces new terminology that reflects the wide range of experiences individuals may have across different sensory modalities.
Redefining Aphantasia: A Multisensory Perspective
Traditionally, aphantasia was understood as the inability to form visual mental images. The recent research now broadens this understanding by introducing new terminology that captures the complexity and diversity of mental imagery experiences:
Multisensory Aphantasia: A condition where the absence of imagery extends across several sensory domains—visual, auditory, olfactory, gustatory, tactile, and kinesthetic.
Global Aphantasia: An extreme form where individuals report a complete lack of mental imagery across all sensory modalities.
Modality-Specific Aphantasia: This refers to the absence of imagery in a specific sensory domain, such as the inability to imagine sounds (auditory aphantasia) while retaining visual mental imagery.
Hypophantasia: A newly defined condition where mental imagery is present but significantly weaker or less vivid than typical. Individuals with hypophantasia may experience vague or fleeting mental images rather than a complete absence.
Types of Aphantasia: Congenital vs. Acquired
Aphantasia does not manifest the same way for everyone, and understanding its origins is crucial for both research and personal identification. The condition can be classified into two distinct types based on when it develops: congenital or acquired. The study differentiates between:
Congenital Aphantasia: Present from birth, individuals with this form have never experienced mental imagery.
Acquired Aphantasia: Developing later in life due to neurological events, brain injury, or psychological trauma, often leading to the sudden loss of imagery capacity.
Implications of the Expanded Definition
The refined definitions open new research pathways and have significant practical implications. By acknowledging the complexity of mental imagery across various sensory modalities, researchers can better investigate how these experiences—or their absence—affect cognition, memory, and creativity.
The sensory modalities include:
Visual aphantasia the inability to form mental images or visualize in the mind’s eye.
Auditory aphantasia prevents the mental recreation of sounds, voices, or music.
Olfactory aphantasia involves the inability to mentally recreate or imagine smells.
Gustatory aphantasia affects the ability to mentally recreate or imagine tastes.
Motor aphantasia presents as the inability to mentally rehearse or imagine movements or actions.
Tactile aphantasia involves the inability to mentally recreate or imagine sensations of touch or texture.
The refined definitions open new research pathways and have significant practical implications:
Self-Identification: The broader terminology allows individuals to better recognise their unique cognitive experiences.
Research Precision: Enables researchers to categorise participants more accurately for studies on cognition and imagination.
Tailored Interventions: Educators, therapists, and mental health professionals can develop more personalised support strategies for those with varying forms of aphantasia.
Why These New Terms Matter
The updated scientific framework presented by the Aphantasia Network, highlights the vast diversity of mental imagery experiences, promoting a more nuanced and inclusive understanding of human cognition. By introducing terms like multisensory aphantasia, global aphantasia, and hypophantasia, the framework reflects the wide range of ways people experience—or lack—mental imagery.
This deeper understanding ensures more accurate recognition of individual cognitive differences and lays the groundwork for more targeted research. Expanding this lexicon is a positive step toward encouraging further exploration, helping researchers refine their studies and fostering better support for those with these unique cognitive profiles.
Conclusion
The evolving definition of aphantasia reflects the complexity and diversity of how individuals perceive their inner worlds. By expanding the framework to include multisensory experiences and newly defined terms like hypophantasia, researchers and practitioners can better understand and support those affected. This refinement not only deepens scientific research but also fosters greater awareness and acceptance of cognitive differences. As the lexicon continues to grow, it will pave the way for more accurate diagnoses, targeted interventions, and a more inclusive understanding of human imagination.
