We investigated whether the accuracy of grammatical morphemes in second language (L2) learners' writing is associated with usage-based distributional factors. Specifically, we examined whether the accuracy of L2 English inflectional morphemes is associated with the availability (i.e., token frequency) and contingency (i.e., token frequency…

Previous research has demonstrated the effectiveness of captioning in second language (L2) comprehension and vocabulary learning. However, little attention has been paid to its potential in supporting grammar development, another challenging area in L2 acquisition. In this research, we used a randomised control design to investigate the role of…

Adult learners have persistent difficulty processing second language (L2) inflectional morphology. We investigate associative learning explanations that involve the blocking of later experienced cues by earlier learned ones in the first language (L1; i.e., transfer) and the L2 (i.e., proficiency). Sagarra (2008) and Ellis and Sagarra (2010b) found…

The current study investigates the limited attainment of adult language acquisition in terms of an associative learning phenomenon whereby earlier learned cues attentionally block those that are experienced later. Short- and long-term blocking are demonstrated in experimental investigations of learned attention in the acquisition of temporal…

This study investigates associative learning explanations of the limited attainment of adult compared to child language acquisition in terms of learned attention to cues. It replicates and extends Ellis and Sagarra (2010) in demonstrating short- and long-term learned attention in the acquisition of temporal reference in Latin. In Experiment 1,…

The aspect hypothesis (Andersen & Shirai, 1994) proposes that language learners are initially influenced by the inherent semantic aspect in the acquisition of tense and aspect (TA) morphology. Perfective past emerges earlier with accomplishments and achievements and progressive with activities. Although this hypothesis has been extensively…
