Dr. Fredrickson’s primary area of interest is infant speech perception. She has worked with colleagues to develop a clinical tool to assess infants’ abilities to discriminate speech sounds: Visual Reinforcement Infant Speech Discrimination (VRISD). University of Colorado Hospital now uses this tool regularly as a component of their test battery when working with infants with hearing loss. Recent and future VRISD studies include investigating the development of infant speech perception and how an infant’s ability to discriminate speech sounds relates to physiological changes as well as language abilities. Other areas of interest include auditory processing testing and rehabilitation and clinical supervision.
