Word frequency (WF), number of letter moves, and solution word transition letter probabilities (TP) were related to anagram solution. The solution word TP measure was based on the relative frequencies of correct to incorrect bigrams within the pool of bigrams defined by the letters of the anagram rather than on the absolute frequencies of the correct bigrams. This bigram rank measure, which also took word length and letter position into account, was a powerful predictor of anagram difficulty (p < .001). Likewise, number of letter moves predicted anagram solution strongly (p < .001), but WF was only a marginal predictor (.05 < p < .10). In addition, there were no significant interactions among the three variables, nor wasanagram TP consistently related to anagram difficulty. The results were interpreted in terms of an approach which combined elements of an hypothesis and an S-R mediational theory.
词频（WF）、字母移动次数和解决方案单词转移字母概率（TP）与字谜答案有关。解决方案单词 TP 度量是基于字谜中定义的双字母组的正确到错误双字母组的相对频率，而不是基于正确双字母组的绝对频率。这种考虑到单词长度和字母位置的双字母排名度量是字谜难度的有力预测指标（p<.001）。同样，字母移动次数强烈预测字谜解决方案（p<.001），但 WF 只是一个边缘预测指标（.05<p<.10）。此外，这三个变量之间没有显著的相互作用，字谜 TP 也与字谜难度没有一致的关系。结果根据一种结合假设和 S-R 中介理论元素的方法进行了解释。
