This study examined the differential effects of systematic perception and production practice and the role of musical ability in learning Mandarin tone-words by native English-speaking adults in a training study. In this study, all participants (N = 38; 19 for each practice group) were first taught declarative knowledge of Mandarin tones and of the target words on the first day. They had to reach criterion performance on the test of vocabulary before they started to engage in either perception or production practice on the second day. Each participant went through three practice sessions on three separate days. Immediate posttests assessing learning outcomes in both perceptive and productive skills were administered on the last day. Musical tonal ability tests were administered to all participants and used as a covariate. The results showed that performance was far worse when participants were tested on the reverse skill than when they were tested on the practiced skill in terms of both error rates and reaction times, providing strong support for the skill-specificity hypothesis. Musical tonal ability was found to correlate with accuracy performance in both tone-word perception and production.

In a visual world paradigm study, we manipulated gender congruence between a subject pronoun and two antecedents to investigate whether second language (L2) learners with a null subject first language (L1) acquire and process overt subject pronouns in a nonnull subject L2 in a nativelike way. We also investigated whether L2 speakers revise an initial interpretation assigned to an ambiguous pronoun when information in the visual context subsequently biased against it. Our results indicated both L1 English speakers and Greek L2 English speakers rapidly used gender information to guide pronoun resolution. Both groups also preferentially coindexed ambiguous pronouns to a sentence subject and current discourse topic, despite the fact that overt subject pronouns in the learners’ L1 index a topic shift. We also observed that L2 English speakers were less likely to revise their initial interpretation than L1 English speakers. These results indicate that L2 speakers from a null subject background can acquire the interpretive preferences of overt pronouns in a nonnull subject L2. The eye-movement data indicate that anaphora processing can become qualitatively similar in native and nonnative speakers in the domain of subject pronoun resolution, but indicate reanalysis may cause difficulty during L2 processing.

Although research shows that repetition increases second language vocabulary learning, only several studies have examined the long-term effects of increasing retrieval frequency in one learning session. With this in mind, the present study examined the effects of within-session repeated retrieval on vocabulary learning. The study is original in that it (a) gave posttests after a delay greater than 2 weeks, (b) employed a paired-associate format to exert strict control over the treatment, (c) considered time-on-task as a factor, and (d) used the same target items for different frequency levels. In this study, 98 Japanese learners studied 16 English-Japanese word pairs using one of the following four retrieval frequency levels: one, three, five, or seven. Results showed that five and seven retrievals contributed to significantly higher scores than one and three retrievals regardless of the posttest timing. When time-on-task was controlled, however, one retrieval led to the largest gain.

This study has aimed to investigate language learners’ emotional experiences through the lens of L2 future self-guides. To that end, the L2 motivational self system was chosen as the theoretical framework to relate learners’ emotions to their L2 selves. However, due to inconsistent results of past research concerning the motivational role of the ought-to L2 self, a revision of the model is proposed, discussed theoretically, and tested empirically. The results revealed a trichotomous model of L2 selves—ideal L2 self, ought-to L2 self/own, and ought-to L2 self/others—with distinct motivational profiles. Furthermore, different types of L2 self-discrepancies were found to result in different emotional reactions on the part of L2 learners. Overall, the study provides a clearer picture of L2 learners’ emotions and their motivation in second language acquisition.

A growing field of research has made use of a semiartificial language paradigm to investigate the role of awareness in L2 acquisition. A central and empirically still unresolved issue in this field concerns the possibility of learning implicitly, that is, without intention to learn and without awareness of what has been learned. Up until now, studies on implicit learning have mainly been conducted in laboratory settings under highly controlled conditions with university students as participants. The present study investigated whether and to what extent the results obtained in such settings can be extrapolated to the general population. Building on Williams (2005), we designed two crowdsourcing experiments that examined the learning of novel form-meaning mappings under incidental conditions in 163 participants. Our design allowed us to disentangle the effects of awareness at the level of noticing and understanding. The results of the two experiments demonstrated the implicit learning effect outside the lab in a more varied sample of participants and indicated that awareness at both levels appears to have a facilitative effect on learning outcomes.

Research with native speakers indicates that, during word recognition, regularly inflected words undergo parsing that segments them into stems and affixes. In contrast, studies with learners suggest that this parsing may not take place in L2. This study’s research questions are: Do L2 Spanish learners store and process regularly inflected, morphologically complex words like native speakers? Does this depend on proficiency? Does type of inflection (verbal or adjectival) play a role? Native speakers, advanced learners, and intermediate learners of Spanish completed two lexical-decision tasks. Response times were measured to target words (verbs or adjectives) preceded by masked primes that were either identical to the targets, morphologically, orthographically, or semantically related, or unrelated. All groups responded more quickly to targets when they were preceded by identical and morphologically related primes than when they were preceded by unrelated primes, with no differences due to either proficiency or inflection type.

The data from this study investigate phrase-final vowel devoicing in Metropolitan French among L1 and L2 speakers, in terms of number of times a speaker devoices a phrase-final high vowel and percentage of the vowel that is devoiced. The goal is to assess whether experienced L2 speakers use style-based variation in response to the same factors as native speakers. Results from a set of role playing and word list tasks revealed that L2 devoicing rates matched those of the natives, but were conditioned by different factors in each group. The duration of L2 speaker devoicing, however, was found not to match native levels. Notable differences emerged in response to shifts in style: L1 speakers showed higher rates and enhanced degrees of devoicing in pragmatic contexts that favored either slower or more formal speech, while L2 speakers responded very little to pragmatic shifts within role plays, instead responding more pronouncedly to different tasks.

This study explores the second language (L2) acquisition of a segment that exists in learners’ first language (L1) and in their L2 but that differs in its phonetic realization and allophonic patterning in the two languages. Specifically, this research tracks development in one aspect of the production of the alveolar lateral /l/ in the L2 Spanish of 85 native English speakers from various levels of study and compares L2 productions to those of native Spanish speakers as well as to learners’ L1 English. Additionally, laterals produced in specific contexts are compared to examine learners’ acquisition of L2 allophonic patterning, as Spanish contains a subset of the lateral allophones that exist in English. Results suggest development toward nativelike norms in the phonetic details of Spanish /l/ and in allophonic patterning. These findings have implications for existing theoretical accounts of L2 speech learning, which cannot adequately account for the learning situation examined.

Understanding how language modality (i.e., signed vs. spoken) affects second language outcomes in hearing adults is important both theoretically and pedagogically, as it can determine the specificity of second language (L2) theory and inform how best to teach a language that uses a new modality. The present study investigated which cognitive-linguistic skills predict successful L2 sign language acquisition. A group (n = 25) of adult hearing L2 learners of American Sign Language underwent a cognitive-linguistic test battery before and after one semester of sign language instruction. A number of cognitive-linguistic measures of verbal memory, phonetic categorization skills, and vocabulary knowledge were examined to determine whether they predicted proficiency in a multiple linear regression analysis. Results indicated that English vocabulary knowledge and phonetic categorization skills predicted both vocabulary growth and self-rated proficiency at the end of one semester of instruction. Memory skills did not significantly predict either proficiency measures. These results highlight how linguistic skills in the first language (L1) directly predict L2 learning outcomes regardless of differences in L1 and L2 language modalities.

This study investigated the relationship between second language (L2) speakers’ success in learning a new morphosyntactic pattern and characteristics of one-on-one learning activities, including opportunities to comprehend and produce the target pattern, receive feedback from an interlocutor, and attend to the meaning of the pattern through self- and interlocutor-initiated eye-gaze behaviors. L2 English students (N = 48) were exposed to the transitive construction in Esperanto (e.g., filino mordas pomon [SVO] or pomon mordas filino [OVS] “girl bites apple”) through comprehension and production activities with an interlocutor, receiving feedback in the form of recasts for their Esperanto errors. The L2 speakers’ interpretation and production of Esperanto transitives were then tested using known and novel lexical items. The results indicated that OVS test performance was predicted by the duration of self-initiated eye gaze to images illustrating the OVS pattern during the comprehension learning activity and by accurate production of OVS sentences during the production learning activity. The findings suggest important roles for eye-gaze behavior and production opportunities in L2 pattern learning.
