Research Interests

The right side of the brain plays an important role in communication, primarily in expressing and understanding intended meaning within a given context. Apragmatism is a disorder of cotenxt-dependent communication associated with damage to the right side of the brain (RHD). Dr. Blake’s research focuses on (a) operationally defining RHD disorders including characteristics of specific impairments and patterns of co-occurrence and (b) examining the incidence and effects of Theory of Mind (the ability to understand that other people have knowledge, thoughts, beliefs, feelings and emotions that are different from your own) in acute through chronic stroke.
