Native language (L1) attrition is ubiquitous in modern globalized society, but its cognitive/psycholinguistic mechanisms are poorly understood. We investigated lexico-semantic L1 attrition in L1 Russian immigrants in Israel, who predominantly use their second language (L2), Hebrew, in daily life. We included Russian monolinguals as a control…

The present study investigates the impact of bidialectalism on L2 production, focusing on the role of dialect modes. Shanghai-Mandarin Chinese bidialectal speakers were recruited to produce second language (L2) English vowels under the influence of either Shanghai or Mandarin Chinese mode. Results showed that in the Shanghai mode, participants'…

We explore how general principles of learning apply to and combine with usage-based approaches to language learning and teaching, with a focus on the effects of order of exposure to new information in second language (L2) instruction. Although the effects of input spacing and timing on memory and learning have been previously explored (see Rogers,…

Second language (L2) grammar learning is difficult. Two frameworks--the psycholinguistic lexical bottleneck hypothesis and the neurocognitive declarative/procedural model--predict that faster L2 lexical processing should facilitate L2 incidental grammar learning. We tested these predictions in a pretest-posttest syntactic adaptation study of…

Chinese learners of English often experience difficulty with English tense presumably because their native language is tenseless. We showed that this difficulty relates to their incomplete conceptual representations for tense rather than their poor grammatical rule knowledge. Participants made acceptability judgments on sentences describing…

This study expands on the practical application of the critical role of auditory processing in the rate of naturalistic L2 speech acquisition. In Study 1, the prosodic production of English by 46 Chinese college students was tracked over a five-month study abroad program in the UK. Learners with extensive L2 input opportunities demonstrated…

This longitudinal study examines the effects of a pre-study abroad (SA) pedagogic intervention and subsequent SA experience on second language (L2) Mandarin fluency. It explores two temporal aspects of oral fluency--planning time and speech rate--along with one performance measure, duration of response. Additionally, L2 contact data were included…

This study investigated how repeating a video-lecture-based task affects second language (L2) learners' processing and incidental acquisition of technical vocabulary as well as the relationship between processing and lexical gains. The participants were 75 Chinese learners of L2 English. Thirty participants performed the task once (control group),…

This study investigated how students' self-reported individual differences predicted second language (L2) spoken discussion task output, an objective behavioral outcome, in the Japanese university English as a Foreign Language (EFL) context. Although numerous psychological theories are used as a rationale for task-based language teaching (TBLT),…

This study examined the relationship of linguistic complexity, captured using a set of lexical richness, syntactic complexity, and discoursal complexity indices, to second language (L2) learners' perception of text difficulty, captured using L2 raters' comparative judgment on text comprehensibility and reading speed. Testing materials were 180…

Learning multiword expressions (MWEs) typically involves exposure to language input, such as through reading and listening. However, this way of learning can be rather slow. Therefore, finding strategies to enhance learning from input is crucial for language acquisition. In this study, 80 Iranian learners of English as a foreign language read…

This study reports on strategies to indicate plural referents in hearing learners of Sign Language of the Netherlands. This is the first explorative study that focuses on L2 expressions of plurality in a sign language. Using data from two datasets, I examined when learners start to express plural and which strategies they apply, and I noted…

Color terms divide the color spectrum differently across languages. Previous studies have reported that speakers of languages that have different words for light and dark blue (e.g., Russian "siniy" and "goluboy") discriminate color chips sampled from these two linguistic categories faster than speakers of languages that use…

A handful of second language (L2) studies have explored "bidirectional pragmatic transfer": "forward pragmatic transfer"--the influence of learners' first language (L1) on their L2--and "reverse pragmatic transfer"--the impact of learners' L2 on their L1. This explanatory sequential mixed-methods study investigated…

In this paper, we report a longitudinal study of the effects of procedural task repetition on learners' task performance (i.e., syntactic complexity in relation to lexical complexity). We investigated how task repetition results in differences at the group and individual level across each task interval (T = 7). Intermediate-level Saudi learners of…
