Abstract:
The current study was a replication of Petursdottir and Aguilar (Journal of Applied Behavior Analysis, 46, 58-68, 2016). Two different stimulus presentations were evaluated during auditory-visual discrimination training. A sample-first procedure, in which the sample stimulus was presented before the comparison stimuli, was compared to a comparison-first procedure, in which the sample presentation was presented after the comparison stimuli. The results indicated that both participants learned more quickly in the comparison-first condition, a finding that differed from Petursdottir and Aguilar (Journal of Applied Behavior Analysis, 46, 58-68, 2016).
