A Stevens's Power Law Check-up of GPT-5.5's Implicit Reading of Visual Encoding

Read the original on arXiv Computer Vision →

The paper adapts Stevens's power law to assess how AI models, specifically GPT‑5.5, implicitly interpret visualizations. In a pilot study, the model first estimates the magnitude of a reference visual representation and then compares subsequent images of the same representation, without access to legends or colormap names. The evaluation covers twelve visual variables, aiming to make algorithmic reading of visual encodings measurable, comparable to human perception, and more transparent.

When to Call an Apple Red: Humans Follow Introspective Rules, VLMs Don't

The paper introduces the Graded Color Attribution (GCA) dataset, a benchmark that tests whether Vision‑Language Models (VLMs) and humans can articulate and follow a threshold rule for labeling objects by color. In experiments, humans consistently adhere to their stated rules, while VLMs—despite accurately estimating color coverage—often violate their own introspective rules, especially when world‑knowledge priors are present. This discrepancy highlights a miscalibration in VLM self‑knowledge that differs from human cognition.
