许多报告声称，人类对具有多种含义的单词的词汇判断速度比对只有一种含义的单词的词汇判断速度更快。用并行分布式处理模型来模拟这种歧义效应是一个挑战，因为激活歧义词会在语义层面上产生竞争；这应该会导致歧义词的处理效率更低而不是更高。尽管存在这个问题，但目前的模拟表明，当网络通过使用邻近因子进入学习的语义模式时，可能会产生歧义效应。然而，竞争并不能完全通过邻近性来对抗，因为在超过50%的试验中，网络未能形成一个学习的歧义单词的语义模式。进一步的模拟表明，增加正确解决比例的操作会导致这种模糊效应的损失
A number of reports claim that humans perform lexical decisions faster to words with many meanings than to words with only one meaning. It is a challenge to simulate this ambiguity effect with a parallel distributed processing model because activation of ambiguous words produces competition at the semantic level; this ought to lead to less rather than more efficient processing of ambiguous words. Despite this problem, the present simulations show that it is possible to produce an ambiguity effect when the network settles into a learned semantic pattern through use of a proximity factor. However, competition is not completely countered by proximity as the network fails to settle into a learned semantic pattern for ambiguous words on more than 50% of the trials. Further simulations show that manipulations that increase the proportion of correct settling result in the loss of thi ambiguity effect
