This study investigated how computer agents' language style affects summary writing in an Intelligent Tutoring System, called CSAL AutoTutor. Participants interacted with two computer agents in one of three language styles: (1) a "formal" language style, (2) an "informal" language style, and (3) a "mixed" language…

Grammatical and lexical cohesion are necessary conditions to guarantee a text's coherence (Halliday and Hasan 1976). Grammatical cohesion is classified into four types of relation: reference, conjunction, substitution, and ellipsis. This study aims to investigate the use of the cohesive device of reference in written discourse produced by…

Establishing local coherence relations is central to text comprehension. Positive-causal coherence relations link a cause and its consequence, whereas negative-causal coherence relations add a contrastive meaning (negation) to the causal link. According to the cumulative cognitive complexity approach, negative-causal coherence relations are…

This study investigated the usefulness of the Cantonese Linguistic Communication Measure (CLCM) in monitoring changes of narrative production in five Chinese adults with aphasia in the period of spontaneous recovery (SR group) and four who underwent anomia therapies (Tx group). Language samples elicited from a picture description task were…

This study examined the representation of knowledge in text writing in 20 ten-year-old children and 20 adults in the Netherlands. The research analyzed the use of clause linking devices to compose larger text units. Special attention was given to the use of causal relational markers and the extent to which causal relations within the texts matched…

Connected speech of 134 healthy, Canadian French-speaking adults, grouped according to age and education level, was analyzed using an aphasia battery. Results demonstrated that older subjects with less education produced fewer content units and were less efficient in transmitting lexico-semantic information. Effects of age and education level on…
