Debate surrounds processes of visual recognition, with no consensus as to whether recognition of distinct object categories (faces, bodies, cars, and words) is domain specific or subserved by domain-general visual recognition mechanisms. Here, we investigated correlations between the performance of 74 participants on recognition tasks for words, faces and other object categories. Participants completed a counter-balanced test battery of the Cambridge Face, Car and Body Parts Memory tests, as well as a standard lexical decision task with response time (RT) and accuracy as dependent variables. We found that response times were consistently positively and significantly correlated between most object categories; for example, face recognition with body and car recognition, but also with word and non-word recognition. However, correlations between accuracy scores were more limited; for example, face recognition did not correlate with non-word recognition. Additionally, controlling for dyslexia resulted in some correlations becoming more robust (e.g., regular- and irregular-word recognition accuracy) or emerging (e.g., RT between body and real-word recognition), whilst others were partialled out (e.g., recognition accuracy between irregular words and confusable non-words). These results suggest some degree of functional overlap in the neural mechanisms subserving recognition of these different object categories, generally supporting a domain-general view of pattern recognition. This stated, observed relationships were complex. In order to further our understanding of pattern recognition, research investigating the recognition of words, faces and other objects in dyslexic individuals is recommended, as is research examining developmental trajectories of pattern recognition and research exploiting neuroimaging methodologies.
