Cognitive neuropsychology; language processes and spatial attention
Dr. Friedrich's research interests lie in the field of cognitive neuropsychology, specifically in the areas of spatial attention and word recognition. The primary focus of this work is to analyze cognitive impairments that result from brain injury in terms of component process models derived from cognitive psychology. The study of behavioral dissociations and the use of response time methods provide a means of identifying basic operations underlying cognitive functions, which in turn allow brain-behavior relations to be clarified. Current projects include the study of processes influencing spatial orienting in normal adults and how these processes break down to produce spatial attention deficits in brain-injured patients.
