When the four categories of primary school age children were compared (Eidetikers, 13orderliners, After-imagers, and Non-imagers), Eidetikers were not found to possess any unique temperamental traits. However, when Eidetikers were separated into a Change type and a Non-change type the former type was found to score higher on the Anger subscale of Emotionality. Total scares on a new subscale of Emotional Expression suggest that the Change type is significantly more `short tempered' than the Non-change type.
