Abstract: | The type of experience involved with an object category has been regarded as one important factor in shaping of the human
object recognition system. Laboratory training studies have shown that different kinds of learning experience with the same
set of novel objects resulted in different perceptual and neural changes. Whether this applies to natural real-world objects
remains to be seen. We compared two groups of observers who had different learning experiences with faces, using holistic
processing as a dependent measure. We found that, while ordinary observers had extensive individuation experience with faces
and displayed typical holistic face processing, art students who had acquired additional experience in drawing faces, and
thus in attending to parts of a face, showed less holistic processing than did ordinary observers. These results converge
with laboratory training studies on the role of type of experience in the development of different perceptual markers for
different object categories. It is thus insufficient to categorize expertise simply in terms of object domains (e.g., expertise
with faces). Instead, perceptual expertise should be classified in terms of the underlying process or task demand. |
