In 2 experiments, we taught 120 3-year-olds and 120 adults novel words for unfamiliar solid objects or perceptually similar nonsolid substances described as belonging either to the toy domain or the food domain. In a forced-choice task, participants extended the novel words to one of two test items: a same-shape test item (i.e., one that shared a common shape with the standard but differed in colour, texture, or smell) or a same-substance test item (i.e., one that shared a common colour, texture, and smell with the standard but differed in shape). Participants made more same-shape choices in the solid than in the nonsolid conditions. This tendency varied depending on whether the same-shape item differed from the standard in colour, texture, or smell. Participants also made more same-shape choices for items described as toys than for the same items described as food. This tendency was consistent regardless of whether the same-shape item differed from the standard in colour, texture, or smell. The findings confirm previous reports that children's word extensions are affected by the solidity of the referent. They also reveal that these extensions are guided by information about the referent's conceptual domain. Finally, these results provide the first evidence that these extensions are influenced by the smell, texture, and colour of the referent. / Arts, Faculty of / Psychology, Department of / Graduate

Despite claims by some theorists to the contrary, investigators have shown that information about grammatical errors is available to young children learning language via the conversational responses of their parents. The present study described five categories of responses in the conversations of working mothers and fathers to their normally developing two-year-old sons, and investigated whether any of these responses were differentially related to well-formed vs. ill-formed child utterances. Subjects were six middle-class, monolingual (English) parent-child dyads. Parents worked full-time jobs and the children were enrolled in full-time daycare. Within a two week period, four 20-minute conversational samples were audio and video recorded for each dyad in the subjects' homes during freeplay activities of the subjects' choice. Results indicated that the pattern of responses for these six parents was very similar to that reported for other parent-child dyads. The most frequent type of response for all parents was one that continued the conversation without either repeating or clarifying the child's previous utterance. The least frequent type of response was one that explicitly corrected portions of the child's utterance. Of all responses, repetitions--both clarifying and nonclarifying--appeared to be the type of response most differentially related to well-formed and ill-formed child utterances. Exact repetitions were more likely to follow well-formed utterances, while the remaining repetitions were more likely to follow ill-formed utterances. This pattern of differential responses was similar for all six dyads. Very few differences regarding the style or pattern of interaction were noted for fathers and mothers. Implications were drawn regarding the nature of linguistic input that is available to two-year-old children learning language.

The phonological awareness skills of children with language disorders has been well addressed throughout the literature. Research into the phonological awareness skills of children with highly unintelligible speech, however, is still in its infancy. One published study has looked at the relationship between phonological awareness skills in children with persistent phonological impairments and in children with normal phonology (Webster & Plante, 1992). Significantly higher scores were recorded on three of the four phonological awareness measures for the children with normal phonology As phonology improved, so did the children's phonological awareness skills. The purposes of the present study were to determine if there is an improvement in phonological awareness skills of children with highly unintelligible speech who receive speech sound intervention services, and to determine if there is a difference in phonological awareness skills between children who receive a phoneme-oriented treatment approach and those who receive a phonological cycling treatment approach. Children who took part in a larger study (Buckendorf, 1996) in which the effectiveness of the two treatment approaches was examined, were given the Assessment of Metaphonological Skills-Prekindergarten (Hodson, 1995) early in the course of treatment and again 2 to 3 months later. The following specific questions were addressed: 1. Is there an increase in phonological awareness skills for children who receive articulation/phonological intervention? 2. Is there a difference in the amount of improvement of phonological awareness skills for children who receive a phoneme-oriented treatment approach as compared with children who receive a phonological cycling treatment approach? To test if the subject's phonological awareness skills improved from pretest to posttest, a one tailed !-test for paired differences, and the Wilcoxon Matched-Pairs Signed-Ranks test were performed. Results on both of these analyses indicated a statistically significant improvement between pretest and posttest scores. To test if there is a difference in the improvement of phonological awareness skills between the two groups, a !-test for independent samples of group and the Mann-Whitney LI-Wilcoxon Rank Sum W-Test were performed on pretest, posttest, and pretest-to-posttest. Results on both analyses indicated no statistically significant differences between the two groups on any of these variables.

Children with slow expressive language development often catch up to their normally developing peers in expressive language, but may still exhibit difficulties with metalinguistic skills. Research shows that children who have difficulty with phonemic awareness also have difficulty with reading, which is important for success in school. Speech-language pathologists assist children who have difficulty with expressive oral language and facilitate language development in children who have difficulties with learning metalinguistic skills, such as phonemic awareness. The purpose of the present study was to compare the phoneme segmentation skills in three groups of children: (a) children with a history of oral expressive language delay (HELD) (n= 22) who were identified as toddlers with slow developing expressive language, but caught up to their normally developing peers by first grade; (b) children identified as toddlers with slow developing oral expressive language and by first grade still maintained the expressive language delays (ELD) (n= 7); and (c) children who were identified at age two as developing normal oral expressive language and maintained normal oral expressive language development (NL) (n= 23) in first grade. The children participated in a phonological segmentation test. The study answered four questions: Is there a significant difference among the three groups of children in the number of correct responses on a phonological segmentation test at ( 1 ) the one phoneme level, (2) the two phoneme level, (3) the three phoneme level, and ( 4) the total number of correct responses. Utilizing an ANOVA test, a significant difference was found among the groups at the two phoneme level, with a trend toward a significant difference at the one phoneme level. Other significant differences were not found. The difference at the two phoneme level was between the ELD group and the normal group, as well as between the ELD group and the HELD group.
