Object recognition is generally studied as a visual process; however, there is evidence to suggest that conceptual information is recruited in tasks that are thought to be primarily perceptual. Indeed, knowledge can influence the interpretation of visual features and the creation of new perceptual features, and behavioral performance differs between birders, who have experience perceptually identifying birds, and ornithologists, who have extensive book knowledge about specific features. The inferior frontal cortex has been shown to process nonvisual information associated with objects, as demonstrated by conceptual priming with familiar objects and training studies where participants learn semantic associations for novel objects. Activation of this area is often thought to relate to the retrieval of semantic information, but an alternative is that activation in this region reflects recruitment of an executive process that engages and binds task- and category- specific perceptual processes.
