Involuntary imagery shows up unbidden: in dreams, flashbacks, or a sudden memory. Some with aphantasia experience this despite lacking voluntary imagery.

Researchers expand aphantasia definition beyond "inability to visualize." This broader framework impacts how we understand and identify with the condition.

People with aphantasia can’t visualize, but that doesn’t mean we don’t have intrusive thoughts. Intrusive thoughts without imagery can be a whole-body, terrifying experience.

Does aphantasia impact the reading experience? Exploring the relationship between reading preferences and mental imagery.

On rare occasions in the morning, between sleep and awake, when the images from my dreams float behind my eyes, that’s when I revel in what it must be like to “see” imagery.

Pupillometry showed that imagined brightness modulates pupil size, but these changes did not correlate with individual self-reported imagery vividness. This suggests a dissociation between subjective reports and objective physiological measures of imagery.

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.
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.
Nanay · Trends in Cognitive Sciences
Aphantasia is a heterogeneous condition with distinct subtypes, including variations in voluntary control and sensory modalities. Recognizing these differences is essential for developing accurate experimental methodologies and explanations.
