The matching law suggests that behavior is emitted in proportion to the level of reinforcement available. The current study investigated this effect in individuals with autism spectrum disorders (ASD), and focused on the effects of magnitude of reinforcement (Study 1), and rate of reinforcement (Studies 2 and 3), on matching performance. Studies 1 and 2 employed lower functioning children with ASD, and demonstrated matching in both groups, but that the group with ASD displayed greater levels of stimulus bias. Study 3 employed higher functioning children with ASD, and found little evidence of matching, but higher stimulus bias in the group with ASD. These effects suggest a disruption of stimulus control, but not reward sensitivity, in individuals with ASD.
匹配定律表明，行为的出现与可获得的强化水平成正比。本研究调查了自闭症谱系障碍（ASD）个体中的这种效应，并关注了强化幅度（研究 1）和强化率（研究 2 和 3）对匹配性能的影响。研究 1 和 2 采用了功能较低的 ASD 儿童，并在两组中都表现出了匹配，但 ASD 组表现出了更高水平的刺激偏差。研究 3 采用了功能较高的 ASD 儿童，几乎没有发现匹配的证据，但 ASD 组的刺激偏差更高。这些结果表明，ASD 个体的刺激控制受到干扰，但奖励敏感性不受干扰。
