Expertise research in the Beyond Categories lab uses several tasks to study the limits of transfer in real-world bird experts from three different geographical regions to investigate the contributions of experience to visual discrimination, perceptual similarity, categorization, and holistic processing. We expect these skills to show limited transfer across regions for experts, with evidence for a subordinate level shift in category structure (that is, expertise should have a more substantial subordinate level category structure). Expertise should also fundamentally change the similarity relationships of exemplars to one-another within categories. These studies will provide clues indicating how experience changes the representations of categories in the brain.
