摘要：Developmentally delayed individuals may respond to certain parts of complex stimuli. One method toinvestigate restricted stimulus control involves conducting training of conditional discriminationcombining simple and complex stimuli and test the responses of participants to individual elements ofthe complex stimuli. This study carried out such tasks with participants with Down’s Syndrome andtypically developing children. Initial training involved identifying matching tasks involving abstractstimuli. Then tests were carried out with four types of trials: 1. simple sample and simple comparisonstimuli; 2. simple sample and complex comparison stimuli; 3. complex sample and simple comparisonstimuli; 4. complex sample and complex comparison stimuli. Participants responded with considerableaccuracy in simultaneous matching to sample tasks. In delayed matching to sample tasks, adults withDown’s Syndrome showed more errors than typically developing children. These results confirmedand extended findings from previous studies in the literature indicating that individuals with adevelopmental delay may not respond under the control of all elements of a stimulus. The findingshave important implications for designing and monitoring teaching procedures in this population.
