Vertical slice

Human Visual Contrast Prior Cue

Walsh et al. OSF human contrast-discrimination slice with probabilistic cues, canonical trials, and descriptive psychometric summaries over a lower-frequency-target signed contrast convention.

Walsh Human Visual Contrast · psychometric by cue

Group Walsh prior-cue trials by cue context and signed target-distractor contrast difference, then compute P(right). Note: the trials CSV for this slice is ~87 MB; the first fetch will be noticeably slow.

Reproduce locally

Run the slice pipeline at this commit

git clone https://github.com/aeronjl/behavtaskatlas.git
cd behavtaskatlas
git checkout ec14ee5
uv sync --extra visual
uv run behavtaskatlas human-visual-contrast-prior-cue-download
uv run behavtaskatlas human-visual-contrast-prior-cue-harmonize
uv run behavtaskatlas human-visual-contrast-prior-cue-analyze
uv run behavtaskatlas human-visual-contrast-prior-cue-report

Extras group visual pulls in the analysis dependencies for this family. Recipe pinned to commit ec14ee5 so a teammate runs the same code path the deploy used.

Artifacts

Slice has a generated local report; the analysis pipeline ran cleanly and produced trial-level output, plots, and provenance.
