Eye-movement patterns of readers with down syndrome during sentence-processing: an exploratory study.

Eye movements were examined to determine how readers with Down syndrome process sentences online. Participants were 9 individuals with Down syndrome ranging in reading level from Grades 1 to 3 and a reading-level-matched control group. For syntactically simple sentences, the pattern of reading times was similar for the two groups, with longer reading times found at sentence end. This "wrap-up" effect was also found in the first reading of more complex sentences for the control group, whereas it only emerged later for the readers with Down syndrome. Our results provide evidence that eye movements can be used to investigate reading in individuals with Down syndrome and underline the need for future studies.

Intentional control and operational constraints in prosodic phrasing: a study of picture-elicited narrations by French children.

This study deals with the determinants of prosodic phrasing in French schoolchildren's narratives. Children (aged 7 to 11) told picture stories to a silent same-age peer. The establishment of temporal and/or causal relations between the events was more or less guided by the drawings (ordered vs. arbitrary sequences). The comprehension of the referential links was more or less supported by the way the frames were displayed (simultaneous vs. consecutive display mode). Four storytelling conditions that differed by the constraints imposed on inference-resolving and memory-searching were thus defined. Naïve French listeners were asked to segment tape-recorded narrations using prosodic variation as a criterion, and to decide whether each prosodic segment was "conclusive" or "continuative." The comparison of the listeners' segmentation labels to those of an expert (functional and formal annotation) showed that more than 91% of the labels corresponded to prosodic boundaries and more than 78% of the non-terminal labels corresponded to non-terminal boundaries, but only 55% of the terminal labels corresponded to terminal boundaries. The storytellers' boundaries were then analyzed as a function of age and storytelling conditions. Non-terminal and terminal boundaries varied with the picture-display mode. Terminal boundaries also depended on the type of event sequence, and non-terminal boundaries on the improvement of the linguistic and communicative skills of the narrators. Terminal judgments of non-terminal boundaries mainly occurred in texts where each event was told in a single proposition either without anaphoric references to the main character or with anaphoric pronouns.

Pitch cues for the recognition of yes-no questions in French.

Linguistic studies of the intonation of Yes-No questions in French show that, in questions containing more than two stress groups, interrogative intonation is characterized by a sequence of lowered pitches or downstepped tones which precede the final rise. The gating paradigm was used here to determine whether subjects listening to French NP utterances containing three stress groups could indicate whether the utterance was an statement or a question before the final rise was heard. Although the task was difficult, findings indicate that listeners can in fact to a certain extent, recognize with mid confidence ratings, the intonational device of a question while they were hearing the downstepped tones preceding the final rise.

On the use of the connective 'and' in oral narration: a study of French-speaking elementary school children.

The study deals with children's use of the connective and to end a story. One hundred and ninety-one children (aged 7.0 to 11.0) who were native speakers of French told two-character comic strip stories with no text to a same-age peer. In the consecutive-display condition, the comic strip was in booklet format with one frame per page, whereas in the simultaneous-display condition, all frames were on the same page. In the arbitrary-sequence condition, the events in each comic strip, although presented as a sequence, could have occurred in any order, whereas in the ordered-sequence condition, the order of the events could not be changed. In the maintained-topic condition, the materials were designed to induce a thematic subject right after the first frame (by the repeated presence of the same character in every picture, up to and including the last one), whereas in the changed-topic condition, the other character appeared alone in the last frame. The analysis focused on cases where the children began the narration of the last frame using and to change the text pattern established so far. The results showed that and was often used in this way (35.2% of the productions), especially in the experimental conditions that facilitated event interconnection (simultaneous display, ordered sequence, maintained topic). The ordered-sequence condition showed that the nine-year-olds in simultaneous display employed and in co-occurrence with another connective, whereas the eleven-year-olds mainly used and more specifically: when the topic changed. The discussion deals with the specialization during development of the use of and within a speaker's discourse.
