Sociolinguistics and Second Language Acquisition is a comprehensive textbook that bridges the gap between the fields of sociolinguistics and second language acquisition, exploring the variety of ways in which social context influences the acquisition of a second language. It reviews basic principles of sociolinguistics, provides a unified account of the multiple theoretical approaches to social factors in second languages, summarizes the growing body of empirical research, including examples of findings from a wide range of second languages, and discusses the application of sociolinguistics to the second language classroom. Written for an audience that extends beyond specialists in the field, complete with summary tables, additional readings, discussion questions, and application activities throughout, this volume will serve as the ideal textbook for advanced undergraduate or graduate students of second language acquisition and instruction, and will also be of interest to researchers in the fields of second language acquisition, second language instruction and sociolinguistics.

This study tests the theoretical predictions regarding effects of increasing task complexity (Robinson, 2001a, 2001b, 2007, 2010; Robinson & Gilabert, 2007) for second language (L2) pronunciation. Specifically, we examine whether more complex tasks (a) lead to greater incidence of pronunciation-focused language-related episodes (LREs) and (b) positively impact accuracy of phonetic form during task completion. Seventeen dyads of intermediate L2 Spanish learners completed simple (+few elements) and complex (-few elements) information-gap map tasks in which the pronunciation of Spanish vowels was made task essential through the inclusion of minimal pair street names (e.g.,Calle Copa“Copa Street” andCalle Capa“Capa Street”). Results revealed no statistical difference in learner-produced pronunciation-related LREs in the simple and complex tasks. Vowel production, however, moved in a targetlike direction for one of five segments (/e/) during the complex task. Results therefore point to some benefits of task complexity manipulations for L2 pronunciation.

Input is a central, driving component in nearly all theories of second language acquisition, but little is known about the relationship between the instructor-provided input to which classroom second language learners are exposed and attested patterns of acquisition. Our study investigates this relationship through an examination of instructors’ Spanish subject expression in oral and written classroom input, as well as their subject expression during three sociolinguistic tasks. Our analysis of five native-speaking instructors’ subject expression, a variable structure, revealed several common patterns across input modes, such as the distribution of the three most common subject forms, as well as subtle differences in the factors constraining use across input modes and tasks. Findings are discussed in relationship to what is known about the acquisition of Spanish subject forms by second language learners, and implications and areas for future research are outlined.

This study explores the impact of study abroad (SA) on second language Spanish phonetic development. Twenty-seven English-speaking learners of Spanish, 15 who were participating in a 4-week SA program in the Dominican Republic and 12 who were studying at their home (AH) institution, were recorded 5 weeks apart (at the approximate beginning and end of their respective programs). Recordings were analyzed acoustically, and four groups of segments were examined: word-initial /p t k/, intervocalic /b d ɡ/, intervocalic /ɾ/ and /r/, and word-final /l/. Productions at Time 1 and Time 2 as well as between the SA and AH groups were compared. Results suggested a minor benefit of the SA environment for phonetic development of some of the segments but with notable individual variation in both groups.

Decades of research on task-based language teaching and learning (TBLT) have demonstrated that tasks may encourage second/foreign language (L2) development by providing conditions for cognitive processes and social interactions that facilitate L2 acquisition (e.g., Long, 2015; Robinson, 2011; Skehan, 2014; for alternative, noncognitive viewpoints on TBLT, see Jackson & Burch, 2017). Specifically, manipulating task features has been shown to draw learners' attention to target forms within meaningbased interaction; to encourage automatization and fluency of target structures; and to promote use of more accurate, varied, and/or complex forms. However, most research examining the facilitative role of tasks and task features thus far has focused on tasks that center on grammatical or lexical structures, or even pragmatics (Plonsky & Kim, 2016). To date, there is a lack of systematic investigation into the role of tasks and task manipulation in promoting opportunities for the development of L2 pronunciation, an important aspect of L2 acquisition and communicative competence. In fact, despite recognition that the theoretical rationale for TBLT includes pronunciation (Ellis, 2009) The authors would like to thank the SSLA editors, board, and editorial assistants for their guidance on this thematic issue; the contributors for their enthusiasm for this idea from the very beginning; external reviewers for their insightful suggestions; and the audience members who attended our colloquium at TBLT 2015. Finally, we would like to thank YouJin Kim for providing feedback on an earlier draft of this introduction. Any remaining oversights are ours.

The present study explored development in Spanish vowel production during a short-term study abroad program. The production patterns of a group of learners studying abroad in a 4-week program in the Dominican Republic were compared in terms of overall vowel quality, tendency to diphthongize /e/ and /o/, and vowel duration to those of a similar group of learners studying in the at-home context. Results revealed no significant changes or differences between groups in vowel quality or diphthongization, but a significant improvement (i.e., reduction) in vowel duration for /a/, /o/, and /u/ for the at-home group only. Findings are discussed in relation to previous research, and areas for future research are outlined.
