Target Color Contrast and Eccentricity in Visual Search: Implications for Control-Panel Design

This repository contains the data, experimental stimuli, R and Python analysis code, statistical results, figures, and supporting materials associated with the study “Target Color Contrast and Eccentricity in Visual Search: Implications for Control-Panel Design.” The study examines the effects of Target Color Contrast and Target Eccentricity on visual attention during visual search in simulated control-panel displays, using Time to First Fixation (TTFF) as the primary eye-tracking measure. The repository is provided to support transparency, reproducibility, and reuse of the research. This updated version adds a sensitivity analysis in which the primary linear mixed-effects model was repeated after excluding the 16 observations with TTFF equal to 0 ms. The corresponding R script and complete numerical results have been added to the repository, and the README has been updated with revised reproduction instructions. The primary dataset and the original analytical approach remain unchanged.
