objnum	Conceptual Complexity	Most of our object stimuli depict a single object against a minimal background. In contrast, the action pictures all involve at least one person, animal or object, and many of them involve two or more protagonists. This is a necessary by-product of the relational meanings that underlie most action verbs. Conceptual Complexity refers to our own subjective rating of the number of objects, animals or persons depicted in each stimulus. These counts applied at the level of the whole object. For example, body parts were not counted separately in pictures of a whole person, nor were separate counts given to the multiple elements in a mass noun (e.g., individual grapes in a cluster of grapes). Surrounding props or substrates for an action were counted separately only if they were critical to the interpretation of the action (e.g., a schematic line indicating the floor or the base of a wall was not counted as a separate object, but the diving board beneath a diving man was counted).
