Establishing Evidence of Learning in Experiments Employing Artificial Linguistic Systems
Peer reviewed Peer reviewed
Direct linkDirect link
Hamrick, Phillip; Sachs, Rebecca – Studies in Second Language Acquisition, 2018
Artificial linguistic systems (ALSs) offer many potential benefits for second language acquisition (SLA) research. Nonetheless, their use in experiments with posttest-only designs can give rise to internal validity problems depending on the baseline that is employed to establish evidence of learning. Researchers in this area often compare…

Reexamining Effects of Form-Focused Instruction on L2 Pronunciation Development: The Role of Explicit Phonetic Information
Peer reviewed Peer reviewed
Direct linkDirect link
Saito, Kazuya – Studies in Second Language Acquisition, 2013
The present study examines whether and to what degree providing explicit phonetic information (EI) at the beginning of form-focused instruction (FFI) on second language pronunciation can enhance the generalizability and magnitude of FFI effectiveness by increasing learners' ability to notice a new phone. Participants were 49 Japanese learners of…

Communicative Focus on Form and Second Language Suprasegmental Learning: Teaching Cantonese Learners to Perceive Mandarin Tones
Peer reviewed Peer reviewed
Direct linkDirect link
Saito, Kazuya; Wu, Xianghua – Studies in Second Language Acquisition, 2014
The current study examined how form-focused instruction (FFI) with and without corrective feedback (CF) as output enhancement facilitated second language (L2) perception of Mandarin tones at both the phonetic and phonological levels by 41 Cantonese learners of Mandarin. Two experimental groups, FFI only and FFI-CF, received a 90-min FFI treatment…

The Incidental Acquisition of English Plural "-S" by Japanese Children in Comprehension-Based and Production-Based Lessons: A Process-Product Study
Peer reviewed Peer reviewed
Direct linkDirect link
Shintani, Natsuko; Ellis, Rod – Studies in Second Language Acquisition, 2011
Most studies that have investigated the effects of instruction on the SLA of specific grammatical features have focused on intentional learning. This study investigated incidental acquisition by comparing the relative effects of two types of instruction--comprehension-based instruction (CBI) and production-based instruction (PBI)--on young…

Processing of the Reduced Relative Clause versus Main Verb Ambiguity in L2 Learners at Different Proficiency Levels
Peer reviewed Peer reviewed
Direct linkDirect link
Rah, Anne; Adone, Dany – Studies in Second Language Acquisition, 2010
This article presents new evidence from offline and online processing of garden-path sentences that are ambiguous between reduced relative clause resolution and main verb resolution. The participants of this study are intermediate and advanced German learners of English who have learned the language in a nonimmersed context. The results show that…

Effects of Form-Focused Practice and Feedback on Chinese EFL Learners' Acquisition of Regular and Irregular Past Tense Forms
Peer reviewed Peer reviewed
Direct linkDirect link
Yang, Yingli; Lyster, Roy – Studies in Second Language Acquisition, 2010
Conducted in English-as-a-foreign-language (EFL) classrooms at the university level in China, this quasi-experimental study compared the effects of three different corrective feedback treatments on 72 Chinese learners' use of regular and irregular English past tense. Three classes were randomly assigned to a prompt group, a recast group, or a…

Implicit and Explicit Corrective Feedback and the Acquisition of L2 Grammar
Peer reviewed Peer reviewed
Direct linkDirect link
Ellis, Rod; Loewen, Shawn; Erlam, Rosemary – Studies in Second Language Acquisition, 2006
This article reviews previous studies of the effects of implicit and explicit corrective feedback on SLA, pointing out a number of methodological problems. It then reports on a new study of the effects of these two types of corrective feedback on the acquisition of past tense -ed. In an experimental design (two experimental groups and a control…
