Eyeballing definition
Eyeballing the means pretty much tells the story. Across the first five “behavioral” items, the differences among icons are significant under pair-wise t-tests (the only exception is between the “angry” and “devious” icons on the generous/selfish item). In other words, subjects perceive the icons as representing different behavioral traits. The same is true with respect to affective (emotive) items. A similar ordering is preserved, with the "happy" icon being the most positively evaluated. The "sad" icon is generally regarded positively, except on the happy/sad item, where it is appropriately rated by subjects.
