To determine whether the effects of noncontingent feedback were transferable, 64 first-grade boys first were given a two-choice discrimination task and then a different contingent task.

This study, which assessed hypothesis-testing abilities using a discrimination-learning paradigm, found that 16 language-impaired primary-level children solved fewer problems than 16 controls equated on cognitive level, but the 2 groups used similar hypothesis types to solve the problems. Type of verbal feedback (explicit versus nonexplicit) did…

This discussion of how conditions of the recipient can affect effectiveness of feedback presents an overview of the topic (feedback functions and feedback about what, when, by whom, and types), and discusses factors affecting formative feedback, i.e., recipients' discrimination repertoires and self-monitoring behavior development in…

Seven adults with severe to profound mental retardation participated in match-to-sample discrimination training under three conditions. Results indicated that error-correction procedures improve performance through negative reinforcement; that error correction may serve multiple functions; and that, for some subjects, trial repetition enhances…
