I am so happy to have been a part of this + @antonlukashevich.bsky.social The study is actually immensely important IMO. So many studies have been designed under the assumption that the link between CDA and individual differences in memory is large and robust. We find that this is not the case. 1/N

reilly-lab.github.ioJoin Lexical Norms to Your Word ListYour 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.

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

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

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

Icelandic Vision Lab
@icevislab.bsky.social

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

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

Icelandic Vision Lab
@icevislab.bsky.social

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

Icelandic Vision Lab
@icevislab.bsky.social

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

Icelandic Vision Lab
@icevislab.bsky.social

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
