Abstract

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