Recent findings show that people with dyslexia have an impairment in serial-order memory. Based on these findings, the present study aimed to test the hypothesis that people with dyslexia have difficulties dealing with proactive interference (PI) in recognition memory. A group of 25 adults with dyslexia and a group of matched controls were subjected to a 2-back recognition task, which required participants to indicate whether an item (mis)matched the item that had been presented 2 trials before. PI was elicited using lure trials in which the item matched the item in the 3-back position instead of the targeted 2-back position. Our results demonstrate that the introduction of lure trials affected 2-back recognition performance more severely in the dyslexic group than in the control group, suggesting greater difficulty in resisting PI in dyslexia.
最近的研究结果表明，患有诵读困难症的人在序列顺序记忆方面存在缺陷。基于这些发现，本研究旨在验证以下假设：患有诵读困难症的人在识别记忆中处理前摄干扰（PI）存在困难。一组25名患有诵读困难症的成年人和一组匹配的对照组接受了一个2-back识别任务，该任务要求参与者指出一个项目是否与2次试验前呈现的项目（不）匹配。通过诱饵试验引发前摄干扰，在诱饵试验中，项目与3-back位置的项目匹配，而不是目标2-back位置的项目。我们的结果表明，引入诱饵试验对诵读困难症组的2-back识别表现的影响比对对照组更严重，这表明诵读困难症患者在抵抗前摄干扰方面存在更大困难。
