How to join zillions of lexical norms to each word in your language sample the easy way: a quick tutorial and demo reilly-lab.github.io/Jamie_JoinLe...
Science is good. We should fund it.
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
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
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).
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 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
VIVAS color saturation distributions show that food imagery is particularly colorful, while imagery for novel objects is less vivid than for other categories.
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 dimensions: Opacity, sharpness, color saturation
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
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
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.

New Paper! w. Léa Entzmann and Árni Kristjánsson
TL;DR: Endpoint deviations are determined by current target-previous distractor difference, but do not reflect the shape of the previous distractor distribution. Saccadic latencies do reflect these distributions.

Question for my fellow vision researchers: anyone know of work where people looked at dynamic ensemble perception for lots of boxes on Zoom? Think "what's the average emotion of these people on a group call?"
