I am a theoretical psychologist (APA division 24). I collaborate with experimental psychologists and cognitive neuroscientists for empirical studies involving EEG, fMRI, and MEG (e.g., see papers in Cortex, eNeuro, Cognition, etc.), but my own specialty is to analyse theoretical issues that cannot be addressed by current experimental methods. For example, whether there is any essential connection between attention and consciousness is the kind of question that defies direct empirical testing, at least for now. Besides, I also work on traditional, philosophical questions concerning mind, language, and knowledge. For more about my research, please see: www.tonycheng.net
