Dr. Karen Emmorey is a professor in the School of Speech, Language, and Hearing Sciences at San Diego State University. She is also the Director for the Laboratory for Language & Cognitive Neuroscience. Her research focuses on what sign languages can reveal about the nature of human language, cognition, and the brain. She also investigates the neural correlates of language and nonlinguistic cognitive functions using fMRI and PET.

Dr. Barbara Landau is the Dick and Lydia Todd Professor of Cognitive Science at Johns Hopkins University. Her research examines the relationship between language and space in children and adults. In order to examine the relationships between language and other conceptual domains such as perception and space, some of her other research interests include examining unusual cases of development, such as studies of congenitally blind children, studies of people with Williams syndrome, and studies of spatial representation in individuals who have sustained perinatal stroke.

Dr. Laurence Leonard is the Rachel E. Stark Distinguished Professor in the Department of Speech, Language, and Hearing Sciences. He is also the Director of the Child Language Laboratory at Purdue University. Leonard's current research explores procedures that facilitate children's word learning and retention. Some of his other research includes examining characteristics of adults' linguistic input that might be misinterpreted by children with specific language impairment, leading them to produce many of the grammatical errors frequently documented for this children. 

Dr. Bob McMurray is a Professor in the Department of Psychological and Brain Sciences at the University of Iowa and is the director of the MACLab. He studies on-line spoken word recognition and speech perception in typical adults and in people with language impairment and cochlear implants. He also studies the development of speech perception and word learning in infants and children. In order to address some of these research questions, his methods include eye tracking, cognitive neuroscience techniques, and computational modeling. 

Dr. Elizabeth Stine-Morrow is a Professor in the department of Educational Psychology at the University of Illinois at Urbana-Champaign. Her research focuses on the multifaceted nature of adult development and aging, and in particular, how cognition and intellectual capacities are optimized over the adult life span. She has examined how self-regulated adaptations, such as selective allocation of attentional resources, reliance on knowledge-based processes, and others, engender positive development in adulthood. Much of this research has focused on the important role of literacy and the processes through which effective reading is maintained into late life.
