This paper quantifies differences in speaking rates in a first and second language, and examines the effects of slower rates on the speakers' abilities to convey information. The participants were 14 fluent (CEF B2/C1) English L2 speakers who held the same oral presentation twice, once in English and once in their native Swedish. The temporal…

One of the most controversial policies in minority education concerns the so-called inland ethnic minority schools or classes in Han-inhabited areas in China. From 2000 onward, the boarding Xinjiang Classes have been established in the eastern cities of China for high school students from the Xinjiang Uyghur Autonomous Region to educate young…

The authors investigated whether speakers who named several objects processed them sequentially or in parallel. Speakers named object triplets, arranged in a triangle, in the order left, right, and bottom object. The left object was easy or difficult to identify and name. During the saccade from the left to the right object, the right object shown…

Listeners are faced with enormous variation in pronunciation, yet they rarely have difficulty understanding speech. Although much research has been devoted to figuring out how listeners deal with variability, virtually none (outside of sociolinguistics) has focused on the source of the variation itself. The current experiments explore whether…

Purpose: The authors examined the effects of utterance length and linguistic complexity on speech movement consistency for 210 participants between the ages of 5 and 22 years. Variability and durational analyses were conducted to (a) determine a more complete picture of the developmental course of earlier observations of the effects of linguistic…

Locus equations (LEs) were derived from consonant-vowel-consonant (CVC) syllables produced by four speakers with profound hearing loss. Group data indicated that LE functions obtained for the separate CVC productions initiated by /b/, /d/, and /g/ were less well-separated in acoustic space than those obtained from speakers with normal hearing. A…

Why is it that young children use connectives correctly in conversation, yet frequently err when asked to use the same connectives in formal reasoning? One possibility is that connective acquisition is item-based in which usage rules are induced from natural language input. This possibility was evaluated by examining the correspondence between the…

Purpose: The present study was designed to investigate the performance of preschool children with specific language impairment (SLI) and their typically developing (TD) peers on sustained selective attention tasks. Method: This study included 23 children diagnosed with SLI and 23 TD children matched for age, gender, and maternal education level.…

Variation set structure--partial overlap of successive utterances in child-directed speech--has been shown to correlate with progress in children's acquisition of syntax. We demonstrate the benefits of variation set structure directly: in miniature artificial languages, arranging a certain proportion of utterances in a training corpus in variation…

The purpose of this study was to examine 32 mothers' sensitivity to social contingency during face-to-face interaction with their two- to four-month-old infants in a closed circuit TV set-up. Prosodic qualities and vocal sounds in mother's infant-directed (ID) speech during sequences of live interaction were compared to sequences where expressive…

The "weaker links" hypothesis proposes that bilinguals are disadvantaged relative to monolinguals on speaking tasks because they divide frequency-of-use between two languages. To test this proposal, we contrasted the effects of increased word use associated with monolingualism, language dominance, and increased age on picture naming times. In two…

Theoretical accounts of both speech perception and of short term memory must consider the extent to which perceptual representations of speech sounds might survive in relatively unprocessed form. This paper describes a novel version of the serial recall task that can be used to explore this area of shared interest. In immediate recall of digit…

The purpose of this study was to investigate the impact of visual strategies with preschool children with autism spectrum disorders (ASD) and their peers during play group sessions. A changing-criterion design was implemented with three preschool-aged children with ASD while they participated in play groups with four typically-developing peers.…

Prosody or speech melody subserves linguistic (e.g., question intonation) and emotional functions in speech communication. Findings from lesion studies and imaging experiments suggest that, depending on function or acoustic stimulus structure, prosodic speech components are differentially processed in the right and left hemispheres. This direct…

This is the first of two articles which will explore how written personal stories promote creativity, competence, belonging, self-expression, and a sense of purpose among students who, for a variety of reasons, have been labeled "at risk" or "delinquent." They present scenarios of students, teachers, elders, and others working together and samples…
