Null hypothesis testing has long since been the 'go-to analytic approach' in quantitative second language (L2) research (Norris, 2015, p. 97). To many, however, years of reliance on this approach has resulted in a crisis of inference across the social and behavioral sciences (e.g., Rouder et al., 2016). As an alternative to the null hypothesis…

This dissertation consists of three manuscripts. The manuscripts contribute to a budding "methodological reform" currently taking place in quantitative second-language (L2) research. In the first manuscript, the researcher describes an empirical investigation on the application of two well-known effect size estimators, eta-squared (eta…

This chapter introduces three applications of Bayesian inference to common and novel issues in second language research. After a review of the critiques of conventional hypothesis testing, our focus centers on ways Bayesian inference can be used for dealing with missing data, for testing theory-driven substantive hypotheses without a default null…

This study investigated whether second language (L2) learners of English could learn to produce stranded prepositions through structural priming. Structural priming is the tendency for speakers to repeat the structure of previously experienced sentences, without intention or conscious awareness of such behaviour, and is thought to be associated…

Whereas studies show that comprehensible output facilitates L2 learning, hypothesis testing has received little attention in Second Language Acquisition (SLA). Following Shehadeh (2003), we focus on hypothesis testing episodes (HTEs) in which learners initiate repair of their own speech in interaction. In the context of a one-way information gap…

This study investigates how figurative language is processed by learners of a second language (L2). With an experiment testing L2 comprehension of figurative expressions in three categories, each combining shared and unshared first language (L1) and L2 lexical representations and conceptual representations in a different way, the study…

This study investigates the dynamics in the Spanish classroom between heritage language learner (HLL) dyads, second language learner (L2L) dyads, and mixed HLL-L2L dyads. Specifically, it examines oral, written and embodied discourse that informs our understanding of how learners attend to language. Analysis for this dissertation examined…

The central goal of this dissertation is to explore the relative perceptibility of vowel epenthesis in English onset clusters by second language learners whose native language is averse to onset clusters. The dissertation examines how audible vowel epenthesis in different onset clusters is, whether this perceptibility varies from one cluster to…

In this article, we present a study that tests the Interface Hypothesis (Sorace and Filiaci, 2006) at the syntax-pragmatics interface and its possible extension to the syntax-morphology interface in two groups of first language (L1) speakers of Shipibo with different levels of formal instruction in Spanish as a second language (L2). Shipibo is a…

This study examines the acquisition of the English laryngeal system by native speakers of (Belgian) Dutch. Both languages have a two-way laryngeal system, but while Dutch contrasts prevoiced with short-lag stops, English has a contrast between short-lag and long-lag stops. The primary aim of the article is to test two hypotheses on the acquisition…

This article examines the acquisition of Korean imperfective markers, the progressive "-ko iss-" and the resultative "-a iss-," with a view to understanding how tense/aspect morphology expands beyond prototype associations with inherent aspects of the verbs. We hypothesized that "-a iss-" will develop later than "-ko iss-," but that the…

We present the results from an experiment that tests the perception of English consonantal sequences by Korean speakers and we confirm that perceptual epenthesis in a second language (L2) arises from syllable structure restrictions of the first language (L1), rather than linear co-occurrence restrictions. Our study replicates and extends Dupoux,…

The aim of this article is two-fold: to test the Aspect Hypothesis, according to which the early use of tense-aspect morphology patterns by semantic/aspectual features of verbs, and Tense is initially defective (e.g. Antinucci and Miller, 1976; Bloom et al., 1980; Andersen and Shirai, 1994; 1996; Robison, 1995; Shirai and Andersen, 1995;…

The point of departure of this study is the well-known hypothesis according to which structures that involve the syntax-pragmatics interface and instantiate a surface overlap between two languages are more vulnerable to crosslinguistic influence than purely syntactic domains (e.g. Muller and Hulk, 2001). In exploring the validity of this…

While resumptive pronouns (RPs) are generally not allowed in English relative clauses, Chinese allows the use of RPs in indirect object position and genitive position but not in subject and direct object positions. Arabic languages allow RPs in direct object position as well as in indirect object position and genitive position, although not in…
