title: Discrimination, translation, or response organization: a clarification of factors underlying slower responding among mentally retarded persons.
abstract: Apparently contradictory findings regarding the locus of information-processing differences between retarded and nonretarded persons were discussed. We suggested that these apparent contradictions may be due to differences in the relative involvement of central processes associated with perception, stimulus--response translation, and response programming in the experimental tasks that have been used in this type of research.
