Abstract

Eight handicapped youths were taught arbitrary matching between visual sample stimuli and visual comparison stimuli: Given Sample A1, selecting Comparison B1 was reinforced; given A2, selecting B2 was reinforced. During nonreinforced test trials consisting of novel samples, novel comparisons, and familiar B comparisons, subjects selected the novel comparisons. Compared to intervening preference tests between novel comparisons, these results suggested that selecting the novel stimuli was controlled by the B comparisons, a phenomenon called exclusion. Some subjects continued to select the same novel comparisons during subsequent preference tests, suggesting that control by exclusion may result in arbitrary matching in new contexts. emonstrated symmetry of AB matching (i.e., BA matching) suggested that A stimuli should also control novel comparison selection; however, these subjects did not show exclusion, but most often selected the A comparisons.

在任意样本匹配中通过排除控制
对8名残疾青少年进行视觉样本刺激与视觉比较刺激的任意匹配:给定样本A1,强化选择比较B1;给定A2,选择B2加强。在由新样本、新比较和熟悉的B比较组成的非强化测试试验中,受试者选择新比较。与新比较之间的干预偏好测试相比,这些结果表明,新刺激的选择是由B比较控制的,这种现象被称为排斥。在随后的偏好测试中,一些受试者继续选择相同的新比较,这表明通过排除控制可能导致在新环境中任意匹配。AB匹配(即BA匹配)的对称性表明,A刺激也控制着新的比较选择;然而,这些受试者没有表现出排斥,但大多数情况下选择了A比较。
