The pupillary light response as a physiological index of aphantasia, sensory and phenomenological imagery strength

eLife, 2022
The pupillary light response is an important automatic physiological response which optimizes light reaching the retina. Recent work has shown that the pupil also adjusts in response to illusory brightness and a range of cognitive functions, however, it ...

The Architect Who Lost the Ability to Imagine: The Cerebral Basis of Visual Imagery

Brain Sciences, 2020
While the loss of mental imagery following brain lesions was first described more than a century ago, the key cerebral areas involved remain elusive. Here we report neuropsychological data from an architect (PL518) who lost his ability for visual imagery

Pupil Size Reflects Trial-Level Variability in Imagery Vividness During Immersive Storytelling but Not (or Hardly) Individual Differences in Trait Imagery. [PDF]

Psychophysiology
ABSTRACT Previous research has shown that the eyes' pupils are larger when imagining dark as compared to bright objects or scenes. On the basis of this, it has been claimed that pupil size is a sensitive marker of mental imagery vividness. We investigated this claim in three experiments, conducted in two countries (Norway and The Netherlands; Ntotal ...

Aphantasia: In search of a theory

Mind & Language, 2022
Though researchers working on congenital aphantasia (henceforth “aphantasia”) agree that this condition involves an impairment in the ability to voluntarily generate visual imagery, disagreement looms large as to which other impairments are exhibited by aphantasic subjects.

Imageless imagery in aphantasia: decoding non-sensory imagery in aphantasia

, 2023
Abstract Activity in early visual cortex is thought to tightly couple with conscious experience, including feedback-driven mental imagery. However, the state of mental imagery, what takes its place or how any activity relates to qualia in those with aphantasia (a complete lack of visual imagery) remains unknown. In the current study, univariate

Affective processing in aphantasia and potential overlaps with alexithymia: Mental imagery facilitates the recognition of emotions in oneself and others

Biomarkers in Neuropsychiatry
We investigated affective processing in aphantasia (= absent or reduced vividness of mental imagery), considering a possible overlap with alexithymia (= deficits in identifying and describing emotions), as reduced vividness of mental imagery is also ...

A longitudinal exploration of self‐perception, mental images of the self, and depression in young people

JCPP Advances, EarlyView.
Abstract Background Cognitive theories suggest that negative self‐perception is central to the development and maintenance of depression. One way self‐perception is represented is through mental imagery of the self. Despite its theoretical importance, the role of mental images of the self in depression has not been systematically examined.

“I just see nothing. It’s literally just black”: a qualitative investigation into congenital aphantasia

Cogent Psychology
Aphantasia, the inability to form voluntary sensory imagery, is a newly emerging field. While quantitative evidence regarding the prevalence and profile of aphantasia is increasing, few studies have sought to understand in-depth the perspectives of those

‘I used to walk around the playground wondering where all my friends had gone’: The reflections of how adults with developmental prosopagnosia made friends in childhood

British Journal of Special Education, Volume 53, Issue 2, Page 261-270, June 2026.
Abstract Current research into developmental prosopagnosia (DP) estimates a high prevalence rate in the general population, but there exist many gaps in the research. More needs to be learned about the lived experience of those with DP and how to identify it in children. Using reflexive thematic analysis, this study explored the lived experience of how
