This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

Although most children learn to communicate in their first language (L1), there is normal and expected variation in their rate of acquisition across all components of the language system. Until recently, most second language acquisition and second language (L2) researchers have assumed that individual differences (IDs) in L1 acquisition are small…

We take a multidimensional perspective on the development of second language (L2) speaking ability and examine how changes in the underlying cognitive variables of linguistic knowledge and processing speed interact with complexity, fluency, and accuracy over the course of a 3-month Spanish study abroad session. Study abroad provides a unique…

Investigates mixed early two-word utterances by bilinguals to determine whether function words match the language context less frequently than content words. Data collected from two language contexts from a child acquiring English and Spanish from birth were used to identify those two-word utterances occurring in the first 2 months of two-word…

Reports on a qualitative study of dyadic discourse between university students of Spanish as a foreign language. Explored the social and cognitive behavior of learners as they participated in second language speaking activities. Repair, as it is formulated in the ethnomethodological approach to conversation analysis provided the lens through which…

Examines the difficulty foreign language learners of Spanish experience in distinguishing between indicative and subjunctive moods after four semesters of study. An analysis of two oral production tasks suggests that, at this intermediate level, they are unlikely to possess enough linguistic foundation to fully benefit from instruction in mood…

A study of the effectiveness of a language proficiency testing method using partial dictation is reported. The study used 60 undergraduate students at a Mexican university studying English as a second language under a traditional four-skills approach. The partial dictation exam was a combination of dictation and cloze procedure. The entire text is…
