Abstract
Description
Under the direction of Dr. Isabel Gauthier, PhD and Olivia Cheung, this experiment establishes new grounds in the theoretical debate of object perception—between the domain-specific hypothesis and the expertise hypothesis. Using spatial frequency adaptation, the results from this study will provide more evidence in support of the expertise hypothesis. The results will test whether expertise processing (here, face processing) is significantly different from object processing. Participants were adapted to a range of spatial frequencies (high/low) and an image category (face/car) to determine if adaptation effect would remain within the image category. Also, bird and car expertise was measured to analyze the interaction between expertise and category specific spatial frequency adaptation. While the correlations between adaptation and expertise were not significant, some adaptation effects were significant and support the need for further research.
