Congenital Aphantasia initially described a lifelong inability to visualise. But it is now understood to manifest as imaginative inabilities that can …

Join Lexical Norms to Your Word List
Your word list should ideally be nested in Tidy format (one word per row, within one column of a dataframe). Your word vector should NOT be a factor but a chr. Set up your word list like this. You can split/unlist a language sample to get it in this format also.

TAKE-HOME: -VIVAS measures imagery using visual dimensions -Color imagery dissociates from structural clarity -Food shows enhanced color imagery -Novel, unfamiliar objects elicit consistently weaker imagery -VIVAS and VVIQ correlate moderately, with striking individual-level dissociations 9/9
020
Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
These findings suggest that visually anchored and verbally prompted imagery measures capture overlapping but distinct components of imagery, and that anchoring imagery judgments to perceptual dimensions reveals structure that standard self-report tools cannot easily assess. 8/9
120
Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
VIVAS correlates only moderately with the VVIQ, well below the ceiling set by their respective reliabilities, and shows striking individual-level dissociations: some individuals scoring in the bottom 10% on one measure fall in the top quartile on the other. 7/9
Cross-tabulation by percentiles: we split both VVIQ and VIVAS into five percentile bands based on each score’s position within the sample: 0-10%, 10-25%, 25-75% (middle half; IQR: interquartile range), 75-90%, and 90-100%; equal scores stay in the same band (ties kept together).
111
Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
We administered VIVAS alongside the VVIQ to a probability-based sample drawn from the National Registry of Iceland (N = 205 after exclusions). Complete aphantasia was observed in 4% of participants on VIVAS and 2% on VVIQ, with complete hyperphantasia in 9% and 4% respectively. 6/9
100
Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
Imagery varied systematically by object category in ways that mirror known functional and neural specializations: novel objects elicited uniformly weaker imagery, which underscores the central role of familiarity, while food objects showed selectively enhanced color imagery. 5/9
VIVAS color saturation distributions show that food imagery is particularly colorful, while imagery for novel objects is less vivid than for other categories.

Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
We developed the Visual Imagery Visually Anchored Scale (VIVAS) where people reconstruct mental images of objects from multiple semantic categories using perceptually anchored dimensions. Individual differences in visual imagery partially dissociated into structural clarity and chromaticity. 4/9
VIVAS dimensions: Opacity, sharpness, color saturation
120
Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
This may partly be due to the overreliance on verbal self-report of imagery strength. The most widely used instrument, the Vividness of Visual Imagery Questionnaire (VVIQ), collapses the richness of imagery experience into a single vividness dimension and provides limited perceptual anchoring. 3/9
110
Icelandic Vision Lab @icevislab.bsky.social · 10/04/2026
Visual mental imagery varies widely across individuals, from aphantasia to hyperphantasia, and may play a significant role in cognition, emotion, and mental health. Yet our understanding of imagery's structure remains limited, and its relationship to other constructs is in muddy waters. 2/9
