语块的认知加工因兼具整体认知的经济性与结构语义理解的复杂性而不易探索。本实验研究主要通过测量中国英语学习者对语块短语和非语块短语语法判断的速度和错误率，考察他们处理语块言语的方式。结果表明，在英语言语认知加工中存在语块主效应， 语块呈现出显著的处理优势；习语语块的提取速度显著低于非习语语块，表明语块内部的复杂性对其认知经济性有干扰； 高水平组处理语块的速度显著快于低水平组，因而更趋向采用整体提取认知方式。

Formulaic sequences processing ，due to its coexistence of  integral cognitive economy  and structure and semantic comprehension complexity ，is difficult  to  measure． This  experiment  explores  the  formulaic  sequence  processing  mechanism  em- ployed by  Chinese learners of English through measuring their reaction time and error rate in judging the grammaticality of formu- laic and nonformulaic sequences． It is found out that formulaic sequences provide an unequivocal processing advantage over non- formulaic  sequences in terms of processing speed and accuracy ，that within formulaic sequences ，idiom processing speed is slower and accompanied with more errors than that of non-idioms ，showing the negative influence of structure complexity on processing ， and that the main effect  exists in the variable of language proficiency ，with higher level learners having a tendency of processing the formulaic sequence as a whole with shorter response time and fewer errors．
