Three measures were found to contribute significantly to the prediction of comprehensibility: mean linguistic depth, the number of self-embedded structures in the sentence, and the number of conjoinging transformations in the derivational history of the sentence. (Author/FB)

Many factors influence the comprehension of a linguistic act by a listener or reader. Some, such as maturity, background, and interests of the decoder are nonlinguistic; others, such as the vocabulary and complexity of the morphological and syntactical structures are linguistic in nature. A review of the literature reveals that while studies have…

On the basis of the grammatical theory developed by Noam Chomsky, it is reasonable to presume that the different parts of a sentence may not all be understood with equal facility and speed. One purpose of this study was to determine whether some of the grammatical relations within a sentence were understood more readily than others. Sentences of…

A study inspired by previous research investigated comprehension of three complex English structures by Dutch high school students at three levels of proficiency. Dutch learners responded similarly to speakers of other languages in an earlier study, but had significantly more ease with one structure familiar in Dutch. (MSE)

The ability of 31 institutionalized trainable mentally retarded mongoloid and nonmongoloid subjects (mean IQ=27.5) to comprehend and imitate verbally presented sentences of varying levels of grammatical complexity was examined. Eight stimulus sentences were spoken for four pairs of pictures, simple declarative or kernel, negative, passive, and…
