Research

Dr. Lloyd's research activities focus on augmentative and alternative communication (AAC), and assistive technology (AT) to meet the needs of individuals with cognitive, motor, and/or sensory impairments across the life span. He and his students use both quantitative and qualitative methods.  Investigations range from underlying processes to applied assessment and intervention, including cross-cultural and cross-linguistic studies; the learning, retention, and use of AAC symbols (both aided and unaided); and test accommodations.
