Abstract:
In the present study, the authors explore in detail the level of visual object
recognition at which perceptual color information improves the recognition of color diagnostic
and noncolor diagnostic objects. To address this issue, 3 object recognition tasks,
with different cognitive demands, were designed: (a) an object verification task; (b) a
category verification task; and (c) a name verification task. They found that perceptual
color information improved color diagnostic object recognition mainly in tasks for which access to the semantic knowledge about the object was necessary to perform the task; that is, in category and name verification. In contrast, the authors found that perceptual color
information facilitates noncolor diagnostic object recognition when access to the object’s structural description from long-term memory was necessary—that is, object verification. In summary, the present study shows that the role of perceptual color information in object recognition is dependent on color diagnosticity
