Three groups of 20 subjects received two exposures of a list of ten sentences followed by an immediate written recall test. The sentences varied in syntactic complexity from group to group, but the sentences for the three groups were similar in semantic content. The effect of sentence complexity upon recall performance was not found to be…

Verifying simple sentences generally involves a process wherein the meanings of individual words are combined to form the meaning of the entire sentence. Three experiments are described in which the combination process was investigated by asking subjects to decide whether S-V-Adj-O sentences were true or false. (Author/RM)

Two experiments examined the comprehension of singly and multiply negated sentences. Difficulty of comprehension was measured by the speed and accuracy with which subjects judged the semantic reasonableness of sentences. Marked and negatively prefixed adjectives were a particular focus of the study. (Author/RM)

Sixty-five grade 5-6 children were tested on a verbal recall task involving material of varying semantic and syntactic content. There was no difference between best and poorest readers in their performance on random lists of words, but there were clear differences on meaningful sentences and on syntactically well-formed but semantically anomalous…
