Different measurements of bilingualism and their effect on performance on a Simon task

We investigated how operationalizing bilingualism affects the results on a Simon task in a population of monolingual and bilingual native English speakers (N = 166). Bilingualism was measured in different ways within participants, and the measurements were used both as dichotomous and continuous variables. Our results show that the statistical significance and effect size varied across operationalizations. Specifically, the Composite Factor Score (the Language and Social Background Questionnaire’s general score), showed a bilingual disadvantage on reaction times regardless of how it was used (dichotomously or continuously). When dividing participants into monolinguals and bilinguals based on the Nonnative Language Social Use score (a Language and Social Background Questionnaire subscore), differences in accuracy and reaction times were found between the groups, but the Nonnative Language Social Use score did not predict accuracy when used as a continuous variable (only reaction times). Finally, earlier age of acquisition predicted faster reaction times, but only when used on a continuum. Effect sizes were between the small and medium range. No differences on the Simon effect were found. Our results call for cautiousness when comparing studies using different types of measurements, highlight the need for clarity and transparency when describing samples, and stresses the need for more research on the operationalization of bilingualism.

Quantifying individual differences in native and nonnative sentence processing

Research in sentence processing has increasingly examined the role of individual differences in language comprehension. In work on native and nonnative sentence processing, examining individual differences can contribute crucial insight into theoretical debates about the extent to which nativelike processing is possible in a nonnative language. Despite this increased interest in individual differences, whether commonly used psycholinguistic tasks can reliably measure individual differences between participants has not been systematically examined. As a preliminary examination of this issue in nonnative processing, we report a self-paced reading experiment on garden-path sentences in native and nonnative comprehension. At the group level we replicated previously observed findings in native and nonnative speakers. However, while we found that our self-paced reading experiment was a reliable way of assessing individual differences in overall reading speed and comprehension accuracy, it did not consistently measure individual differences in the size of garden-path effects in our sample (N = 64 native and 64 nonnative participants, and 24 experimental items). These results suggest that before individual differences in sentence processing can be meaningfully assessed, the question of whether commonly used tasks can consistently measure individual differences requires systematic examination.

In defense of ‘copying and restructuring’

In her keynote article advocating the Linguistic Proximity Model for third language (L3) acquisition, Westergaard (2019) presents several arguments against ‘copying and restructuring’ in nonnative language acquisition, mechanisms central to Schwartz and Sprouse’s (1996) Full Transfer/Full Access model of second language (L2) acquisition. In this commentary, we seek to counter her arguments and also show that the results of a large body of studies on nonnative language acquisition are explained only by ‘copying and restructuring’.

The Contributions of Crosslinguistic Influence and Individual Differences to Nonnative Speech Perception

Perception of a nonnative language (L2) is known to be affected by crosslinguistic transfer from a listener’s native language (L1), but the relative importance of L1 transfer vis-a-vis individual learner differences remains unclear. This study explored the hypothesis that the nature of L1 transfer changes as learners gain experience with the L2, such that individual differences are more influential at earlier stages of learning and L1 transfer is more influential at later stages of learning. To test this hypothesis, novice L2 learners of Korean from diverse L1 backgrounds were examined in a pretest-posttest design with respect to their perceptual acquisition of novel L2 consonant contrasts (the three-way Korean laryngeal contrast among lenis, fortis, and aspirated plosives) and vowel contrasts (/o/-/ʌ/, /u/-/ɨ/). Whereas pretest performance showed little evidence of L1 effects, posttest performance showed significant L1 transfer. Furthermore, pretest performance did not predict posttest performance. These findings support the view that L1 knowledge influences L2 perception dynamically, according to the amount of L2 knowledge available to learners at that time. That is, both individual differences and L1 knowledge play a role in L2 perception, but to different degrees over the course of L2 development.

THE EFFECTIVNESS OF MONOLINGUAL COMMUNICATIVE METHOD IN TEACHING ENGLISH LANGUAAGE

This article is about the effectiveness of monolingual communicative method which makes students to be able to understand, speak and think in nonnative language. It also demonstrates variety of teaching methods and techniques, and other language targeted exercises to succeed in this splendid sphere. Much attention was given to the receptive and productive speech activities, which can be defined as the most difficult ones in studying English language.

Infant learning of words in a typologically distant nonnative language

Infants attune to their native language during the first two years of life, as attested by decreases in the processing of nonnative phonological sounds and reductions in the range of possible sounds accepted as labels for native words. The present study shows that French-learning infants aged 1;8 can learn new words in an unfamiliar language, Cantonese, after just 6 repetitions of each word. This shows that word learning in a nonnative language remains possible during the second year of life even in a nonnative language that is typologically distinct from the native language.

Speech Recognition in Noise in Adults and Children Who Speak English or Chinese as Their First Language

Speech recognition of individuals who are listening to a nonnative language is significantly degraded in the presence of background noise and may be influenced by proficiency, age of acquisition, language experience, and daily use of the nonnative language.The purpose of this study is to examine and compare speech recognition in noise performance across test conditions with varying signal-to-noise ratios (SNRs) as well as the presence of vocal and spatial cues in listeners who speak American English as a native language or Mandarin Chinese as a native language. Self-rated English proficiency and experience were collected for native Mandarin Chinese speakers to determine its relationship to performance on the test measures.A cross-sectional repeated measures design was used for the study.Four groups of participants were included in the study. The adult groups consisted of 25 adults who speak native English and 25 adults who speak native Mandarin Chinese with English as an additional language. The pediatric groups consisted of 16 children who speak native English and 16 children who speak native Mandarin Chinese with English as an additional language.Percent correct speech recognition in noise was assessed at three SNRs (−3, 0, +3 dB) using the adult or pediatric versions of the AzBio sentence test. The Listening in Spatialized Noise-Sentence (LiSN-S) test was used to determine the effect of providing spatial and vocal cues on the speech recognition in noise performance of the groups of participants. The data for each age group and test measure were analyzed with a repeated measures analysis of variance. Correlation analyses were performed to examine relationships between English proficiency and experience on performance across the speech recognition test conditions.Analysis of the data from the adult or pediatric AzBio sentence test identified a significant effect of native language for adults but no significant effect for children. The higher SNRs yielded better performance for all listeners. On the LiSN-S test, results for the adult and pediatric groups were similar and showed significantly better performance for the native English speakers in every test condition. The demographic and language characteristics that most affected speech recognition performance across the test measures included the length of time the person lived in the United States, the age of English acquisition, the number of minutes per day English was spoken by the participant, and the self-rated English proficiency.The findings in this study highlight the importance and benefit of higher SNRs as well as the provision of vocal and spatial cues for improving speech recognition performance in noise of adult and pediatric listeners who speak Mandarin Chinese as a native language.
