Open bigram (OB) models (e.g., SERIOL: Whitney, 2001, 2008; Binary OB, Grainger & van Heuven, 2003; Overlap OB, Grainger et al., 2006; Local combination detector model, Dehaene et al., 2005) posit that letter order in a word is coded by a set of ordered letter pairs. We report three experiments using bigram primes in the same-different match task, investigating the effects of order reversal and the number of letters intervening between the letters in the target. Reversed bigrams (e.g., fo-OF, ob-ABOLISH) produced robust priming, in direct contradiction to the assumption that letter order is coded by the presence of ordered letter pairs. Also in contradiction to the core assumption of current open bigram models, non-contiguous bigrams spanning three letters in the target (e.g., bs-ABOLISH) showed robust priming effects, equivalent in size to contiguous bigrams (e.g., bo-ABOLISH). These results question the role of open bigrams in coding letter order.
开放双字母组（OB）模型（例如，SERIOL：惠特尼，2001年、2008年；二元OB，格兰杰和范赫文，2003年；重叠OB，格兰杰等人，2006年；局部组合探测器模型，德阿纳等人，2005年）假定单词中的字母顺序由一组有序字母对编码。我们报告了三项在异同匹配任务中使用双字母组启动刺激的实验，研究顺序反转以及目标中字母之间间隔字母数量的影响。反转双字母组（例如，fo - OF，ob - ABOLISH）产生了强烈的启动效应，这与字母顺序由有序字母对的存在来编码的假设直接矛盾。同样与当前开放双字母组模型的核心假设相矛盾的是，目标中跨越三个字母的非连续双字母组（例如，bs - ABOLISH）显示出强烈的启动效应，其大小与连续双字母组（例如，bo - ABOLISH）相当。这些结果质疑了开放双字母组在编码字母顺序中的作用。
