In this article, we propose a reconceptualization of the principles and parameters (P&P) framework. We argue that in lieu of discrete parameter values, a parameter value exists on a gradient plane that encodes a learner's confidence that a particular parametric structure licenses the utterances in the learner's linguistic input. Crucially,…

This study explores the effects of extensive audio-visual input with three captioning modes -- unenhanced captions, textually enhanced captions, and no captions -- on learning a variety of L2 grammatical constructions and examines the effects of three learnability factors: construction type, frequency, and recency. A total of 112 participants…

This article addresses the benefits of audio-visual input for learning second language (L2) vocabulary and grammatical constructions. Specifically, it explores the role of frequency, the effects of subtitles and captions, and the mediating role of learner proficiency on language gains in two longitudinal studies. Study 1 targets vocabulary…

When viewed through a generic, one-size-fits-all perspective, use of input enhancement does not appear effective. Through analysis of individual grammatical features and different learner proficiency levels, a significant impact may be revealed. To study the impact of input enhancement on diverse grammatical features, 16 short reading texts and…

This paper presents an experimental study of the rarely explored question of how input through instruction interacts with L2 acquisition at the level of modular linguistic knowledge. The investigation focuses on L2 knowledge of the English polarity item "any," whose properties are only partially covered by typical language-teaching…

The purpose of this article is to analyze a task included in the LINC Home Study (LHS) program. LHS is a federally funded distance education program offered to newcomers to Canada who are unable to attend regular LINC classes. A task, in which a language structure (a gerund) is chosen and analyzed, was selected from one instructional module of LHS…
