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

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.

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.

Ten years after aphantasia was named, Adam Zeman argues it likely has several subtypes and that most abilities are spared, with memory for one's own past differing most. He urges an open mind in this young field.

Aphantasia is not a monolithic condition, as many individuals retain involuntary imagery like dreams despite lacking voluntary control. This suggests that mental imagery relies on multiple distinct processes that can break down independently.

Among university students, those who rated their imagery as less vivid were less likely to picture something, like a pink elephant, when told not to. This suggests weaker imagery may bring more resistance to unwanted images.

In a new experiment, people with aphantasia rated afterimages as fainter than typical imagers did. Together with a review of other studies, this suggests aphantasia affects images that arise on their own, not only ones made on purpose.

Aphantasics report visual dreams despite lacking voluntary mental imagery, challenging the idea that dreaming is a form of imagination. This suggests that dreaming and voluntary imagery may rely on distinct cognitive and neural mechanisms.

Researchers propose a dichotomous framework for phantom perception, distinguishing between voluntary mental imagery and involuntary experiences like illusions or synesthesia. This classification helps unify diverse sensory phenomena and provides a roadmap for studying the neural mechanisms of constructive perception.
