Exposure to a distorted face results in subsequently viewed distorted faces appearing more normal. This type of face adaptation has been used extensively to probe our representations of human faces. In Experiment 1 we used the face distortion after-effect (FDAE) to explore the role of experience in the processing of unfamiliar individuals from a different species, the domestic dog (Canis familiaris). We adapted our participants to the distorted face of a golden retriever and tested their subsequent normality judgments for various dogfaces that matched the adapting stimulus in identity (both the same and a different image of the same dog), breed, colour (but not shape), shape (but not colour), or in species only (i.e., neither shape nor colour). After adaptation there was a different pattern of normality judgements for dog owners compared to non-owners. Dog owners (n=30) showed a larger FDAE than non-owners (n=25) for same-identity images. The dog owners' FDAE was identity-specific: it was equivalent in size for the same-identity images and transferred significantly less to all other dogs (regardless of breed, shape and colour). For non-owners, the FDAE was equivalent in size for all dogs that were similar in colour (e.g. pale fur with a dark nose). Experiment 2 was conducted to further investigate the role of experience by comparing the FDAE for golden retriever owners and owners of other breeds. Data to date (n=7) suggests a golden retriever-specific effect; the FDAE was more specific for golden retriever owners than it was for owners of other breeds. The findings suggest that experience with different types of faces can affect whether they are represented at a more basic level (e.g., a pale dog) or subordinate level (e.g., an individual golden retriever).
