Background: Constraint-induced (language) aphasia therapy (CIAT), based on constraint usage of the language channel only, massed practice and shaping through therapeutic language games, has been suggested as a more efficient therapy approach than traditional aphasia therapies. Aims: To examine the comparative efficacy of CIAT and a traditional…

The robust relation between maternal education and child language that is observed in monolingual populations has not been reliably replicated among bilingual children from immigrant families in the United States. We hypothesized that a variable that operates in immigrant populations--the language in which mothers achieved their highest level of…

The goal of this study was to investigate non-adjacent consonant sequence patterns in target words during the first-word period in infants learning American English. In the spontaneous speech of eighteen participants, target words with a Consonant-Vowel-Consonant (C[subscript 1]VC[subscript 2]) shape were analyzed. Target words were grouped into…

The relationship between prosody and comprehension, previously demonstrated in K--12 students, was examined in university students enrolled in first-year writing classes. Students completed the Gray Oral Reading Test-5 both before and after an expressive reading intervention (ER) or no oral reading instruction (NI). Throughout the semester, the ER…

Purpose: Cantonese lexical tone awareness is closely associated with 1st language Cantonese vocabulary knowledge, but its role in 2nd language English vocabulary knowledge was unclear. We addressed this issue by investigating whether and, if so, how Cantonese lexical tone awareness contributes to English expressive vocabulary knowledge in Hong…

Infants' pointing is associated with concurrent and later language development. The communicative intention behind the point -- i.e., imperative versus declarative -- can affect both the nature and strength of these associations, and is therefore a critical factor to consider. Parents' pointing is associated with both infant pointing and infant…

The present study examined the effects of different types of written input on the learning and retention of collocational knowledge. Eighty-three second language (L2) learners from four intact classes were divided into a control group and three treatment groups. The treatment groups were provided with infrequent grammatical collocations embedded…

Knowing enough vocabulary is crucial for second language learners to comprehend and produce the language. Therefore, a substantial bulk of research has aimed at finding the most effective ways to acquire new words. The Task-induced Involvement Load Hypothesis (Laufer & Hulstijn, 2001) states that vocabulary tasks are efficient when they induce…

Background: Many people with aphasia have word-finding difficulties, with some showing particular difficulties with verbs. Picture-naming therapy is often used to improve naming, but gains are usually limited to therapy items and do not transfer to conversation. Therapy where words are produced in sentences and in real-life activities may be more…

This cross-sectional study investigated first (L1) and second (L2) language receptive and expressive vocabulary in a sample of 542 typically developing bilingual children of immigrants (age range 6-13), coming from six different L1 backgrounds in Norway. Results demonstrated that children's L1 and L2 vocabulary skills increased with age. From a…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…

There have been a number of studies on the use of complaints as a speech act. The majority of these studies have included analysis of how different first language speakers make complaints while only a limited number of studies have examined the effects of instruction on the development of complaints as a speech act. Those that have examined this…

Purpose: We report on a replicated single-case design study that measured the feasibility of an expressive vocabulary intervention for three Cantonese-speaking toddlers with small expressive lexicons relative to their age. The aim was to assess the cross-cultural and cross-linguistic feasibility of an intervention method developed for…

What aspects of infants' prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalizations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they (a) are early instances of intentional communication and (b) elicit verbal responses from caregivers. In…

Contemporary parent-implemented early intervention programs for children with autism spectrum disorder usually incorporate a range of techniques with different theoretical underpinnings. While research suggests that parents often learn to implement interventions with an acceptable degree of overall fidelity, there is limited research into parent…
