Evidence from 3 experiments reveals interference effects from structural relationships that are inconsistent with any grammatical parse of the perceived input. Processing disruption was observed when items occurring between a head and a dependent overlapped with either (or both) syntactic or semantic features of the dependent. Effects of syntactic…

A word-by-word human sentence processing complexity metric is presented. This metric formalizes the intuition that comprehenders have more trouble on words contributing larger amounts of information about the syntactic structure of the sentence as a whole. The formalization is in terms of the conditional entropy of grammatical continuations, given…

Two experiments showed that functional completeness--the explicit propositional surface realization of deep-structure clause relations--isolated effective and integral comprehension units, which definitions of comprehension units couched in levels of syntactic structure failed to do. (Author/RL)

In an experiment investigating aspects of children's comprehension of sentences containing the connective "if," young children judged correct and reversed "Y if X" and "If X, Y" sentences as "sensible" or "silly." The comprehension of the role of "if" in sentences appears to be a…

Research in the active-passive verb relation has indicated that there is an interaction between syntactic form and verb semantics among children of preschool age. The present study examines the contribution of active-passive syntax and verb semantics to comprehension difficulty for preschoolers, 6-year-olds, 7-year-olds, and adults. An additional…

Describes a study that examines the ability of children to identify given/new elements in passive and cleft forms in order to ascertain the relationship between syntactic and pragmatic acquisition. Results indicate that complete competence with these marked sentence forms does not occur universally until some time in adolescence. (SED)

Children, aged 4-12, performed four tasks designed to test their comprehension of complex sentences that contained main verbs taking underlying sentences as their complements. Tasks involved imperatives, semantic anomalies, truth questioning and short-term memory. (JMB)

This study examined the extent of children's awareness of the semantic subtleties of the word "promise" and their comprehension of sentences following an atypical syntactic pattern using "promise" as the main verb. Subjects included children within three months of being six-and-one-half, eight-and-one-half, nine-and-one-half, and ten-and-one-half…

In this report data are presented that challenge the difficulty ordering for anaphoric syntax (e. g., pronouns) proposed by Bormuth, Manning, Carr, and Pearson in 1970. It is suggested that any such difficulty ordering resulting from tests of the form proposed by Bormuth (1970) will have uncontrolled variability due to semantic factors that have…

This article discusses a study designed to ascertain the comprehension of the role of "because" in a sentence in children between the ages of 5;8 and 10;11. (CFM)
