Abstract: This study provides normative data for a set of 80 digital color pictures of widely varying types such as human activities, nature scenes, cartoon characters, and magazine covers. Four objects in each picture were rated by 48 observers on a 6-point Likert scale for their relevance to the overall meaning of the picture. A table is provided that lists, for each picture, brief descriptions of the four objects, their locations in the picture, the means and standard deviations of their relevance ratings, and statistical analyses specifying which pairs of objects in a picture differed significantly on their meaning to the scene. A separate analysis using Salience Toolbox software (Walther & Koch, 2006) provided additional information about whether each of the four relevance-rated objects was high or low in visual salience. An example is provided of how the pictures could be used to create stimuli for a change blindness task in which detection of item onset versus offset is contrasted for low-relevance and high-relevance features.
