The current study investigated disfluency and self-repair in L2 presentational and interpersonal speech to determine whether speech modes may affect L2 self-repair. Knowledge of self-initiated repair behavior in L2 speech is particularly relevant for understanding psycholinguistic processes of L2 speech production. Different speech modes, such as…

Researchers have been investigating the effects of different planning conditions on learners' second language (L2) writing performance. However, whether such effects differ regarding specific planning conditions and task complexity has remained underexplored. This study examined the effects of pre-task planning (PTP) versus unpressured online…

Interaction has received attention in different fields of applied linguistics. In the field of Second Language Acquisition (SLA), scholars have perceived interaction as a platform where L2 learners can engage in language experimentation. It has been considered in light of Long's (1981) Interaction Hypothesis, which posits that negotiation of…

From the perspective of complexity theory and based on Robinson's Cognition Hypothesis and the Triadic Componential Framework, this paper investigated the effect of manipulating task complexity along resource-dispersing dimension on L2 written performance. The results showed that: 1) Significant interactive effects were found between the two…

Bilingual experience has an impact on an individual's linguistic processing and general cognitive abilities. The relation between these linguistic and non-linguistic domains, in turn, is mediated by individual linguistic proficiency and developmental changes that take place across the lifespan. This study evaluated this relationship by assessing…

This study examines possible semantic interaction in fully fluent adult simultaneous and early second language (L2) bilinguals. Monolingual and bilingual speakers of Spanish and English (n = 144) were tested for their understanding of lexical categories that differed in their two languages. Simultaneous bilinguals came from homes in which Spanish…

Movement artifacts are still considered a problematic issue for imaging research on overt language production. This motion-sensitivity can be overcome by functional near-infrared spectroscopy (fNIRS). In the present study, 50 healthy subjects performed a combined phonemic and semantic overt verbal fluency task while frontal and temporal cortex…

The study reported in this paper investigated the relationship between components of aptitude and the fluency, lexical variety, syntactic complexity, and accuracy of performance in two types of written and spoken narrative tasks. We also addressed the question of how narrative performance varies in tasks of different cognitive complexity in the…

This cross-sectional study investigated the bilingual lexical skills of 175 US school-age children (5 to 18 years old) with Cantonese, Mandarin, or Korean as their heritage language (HL), and English as their dominant language. Primary study goals were to identify potential patterns of development in bilingual lexical skills over the elementary to…

This study investigated how task complexity affected native and non-native speakers' speaking performance in terms of a measure of communicative success (functional adequacy), three types of fluency (breakdown fluency, speed fluency, and repair fluency), and lexical diversity. Participants (208 non-native and 59 native speakers of Dutch) carried…

This study employed Bachman and Palmer's (2010) Assessment Use Argument framework to investigate to what extent the use of a second language oral test as an exit test in a Hong Kong university can be justified. It also aimed to help test developers of this oral test identify the most critical areas in the current test design that might need…

From an information processing perspective, humans have a limited attentional capacity for processing information. Thus, second language (L2) researchers have investigated the role of pretask planning in task performance, finding that planning results in greater fluency and complexity but has mixed effects on accuracy. However, most planning…

This study examines the effects of subtitled similar task videos on language production by nonnative speakers (NNSs) in an online task-based language learning (TBLL) environment. Ten NNS-NNS dyads collaboratively completed four communicative tasks, using an online TBLL environment specifically designed for this study and a chat tool in…

As we age, our ability to select and to produce words changes, yet we know little about the underlying neural substrate of word-finding difficulties in old adults. This study was designed to elucidate changes in specific frontally mediated retrieval processes involved in word-finding difficulties associated with advanced age. We implemented two…

Previous studies have found that proficiency in a second language affects how the meanings of words are accessed. Support for this hypothesis is based on data from explicit memory tasks with bilingual participants who know two languages that are relatively similar phonologically and orthographically (e.g., Dutch-English, French-English). The…
