The Southern California Research Institute (SCRI) is a nonprofit organization. It was incorporated in 1973 and its staff has been continuously engaged in research since that date. The institute's purpose is the study of human skills performance, psychomotor behavior, and cognitive skills as they are affected by pharmacological, physical, and psychosocial variables.

SCRI investigators design and execute laboratory experiments, field studies, and surveys. Data are analyzed and findings are reported to clients (government agencies, research organizations, individuals who need assessment of their driving skills, and pharmaceutical companies) and to the scientific community via professional conferences and journals.
