Previous evidence suggests that children's mastery of prosodic modulations to signal the informational status of discourse referents emerges quite late in development. In the present study, we investigate the children's use of head gestures as it compares to prosodic cues to signal a referent as being contrastive relative to a set of possible…

Purpose: To better understand the role of tongue visibility in speech, this study compared the spatiotemporal patterns of silent versus audible speech for lingual consonants of American English. Kinematic data were obtained for articulatory features assumed to be visually salient, including tongue movement (anterior displacement and midsagittal…

Until now, there has been very little unified analysis of metadiscourse across speech and writing. Drawing on a reflexive metadiscourse model, this article conducts a multidimensional analysis of metadiscourse across 10 spoken and written registers in a corpus of 626 texts. Two metadiscourse dimensions, participants' interaction and discourse…

The presence of a human figure in a scene appears to change how people describe it. About 20% of participants take the human figure's viewpoint (Tversky and Hard in Cognition 110:124-129, 2009. http://doi.org/10.1016/j.cognition.2008.10.008). Five exploratory studies compare descriptions of a scene with no person to descriptions of a scene with a…

When communicating with other people, adults reduce or lengthen words based on their predictability, frequency, and discourse status. But younger listeners have less experience than older listeners in processing speech variation across time. In 2 experiments, we tested whether English-speaking parents reduce word durations differently across…

Purpose: This study evaluated interrater reliability (IRR) and test-retest stability (TRTS) of seven linguistic measures (percent correct information units, relevance, subject-verb-[object], complete utterance, grammaticality, referential cohesion, global coherence), and communicative success in unstructured conversation and in a story narrative…

Purpose: Speech perception in noise becomes difficult with age but can be facilitated by audiovisual (AV) speech cues and sentence context in healthy older adults. However, individuals with Alzheimer's disease (AD) may present with deficits in AV integration, potentially limiting the extent to which they can benefit from AV cues. This study…

Drawing on Conversation Analysis, this paper investigates how an English native speaker interviewer utilizes clarification requests as a form of recipient design during an interview to resolve problems of non-understanding. This data is contrasted with interviews between English language learners at a private university in Taiwan. The findings…

Speakers use speech and gestures to represent referents in discourse. Depending on referents' information status, in speech speakers will vary richness of expression (e.g., lexical noun phrase [NP]/pronoun), nominal definiteness (indefinite/definite), and grammatical role (subject/object). This study tested whether these three linguistic markers…

We investigate whether infant-directed speech (IDS) could facilitate word form learning when compared to adult-directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented…

This study examines the discourse basis for referent accessibility and its relation to the choice of referring expressions by children with Autism Spectrum Disorder (ASD) and typically developing children. The aim is to delineate how the linguistic and extra-linguistic context affects referent accessibility to the speaker. The study also examines…

Sighted speakers of different languages vary systematically in how they package and order components of a motion event in speech. These differences influence how semantic elements are organized in gesture, but only when those gestures are produced with speech (co-speech gesture), not without speech (silent gesture). We ask whether the…

Purpose: Politeness markers (PMs) are words that enhance cooperativity in dialogue and are an essential component of professional/work communication. Persons with moderate/severe traumatic brain injury (TBI) underuse PMs in connected speech and have employment stability issues. The voicemail elicitation task (VET) is a standardized computerized…

This article investigates the amount of input and the quality of mother-child interactions in mothers who differ in socio-economic status (SES): mid-to-high SES (mhSES) and low SES. The amount of input was measured as the number of utterances per hour, the total duration of speech per hour and the number of turns per hour. The quality of the…

The current study compared perceived language gains between learners of different preprogram proficiencies, academic interests, and genders who participated in the same predeparture preparation and short-stay service learning program abroad. L2 learners studying Spanish and computer science students participated in a semester-long program to…
