The digital transformation in educational assessment has led to the proliferation of large-scale data, offering unprecedented opportunities to enhance language learning, and testing through machine learning (ML) techniques. Drawing on the extensive data generated by online English language assessments, this dissertation investigates the efficacy…

While recent studies find that contextual diversity (CD) is a better determinant of visual word recognition than token frequency, there is a dearth of work comparing contextual diversity and token frequency in developing readers. In two sets of character and lexical decision experiments we examined token frequency and contextual diversity effects…

The current work uses memory errors to examine the mental representation of verb-particle constructions (VPCs; e.g., "make up" the story, "cut up the meat"). Some evidence suggests that VPCs are represented by a cline in which the relationship between the VPC and its component elements ranges from highly transparent ("cut…

Recent research investigating embedded stem priming effects with the masked priming paradigm and pseudoword primes (e.g., "quickify"--"quick") has shown that priming effects can be obtained even when the embedded target word is followed by a non-morphological ending (e.g., "quickald"--"quick"). Here we…

This article on interactional competence provides an overview of the historical influences that have shaped theoretical conceptualisations of this construct as it relates to spoken language use, leading to the current view of it as involving both cognitive and social dimensions, and then describes its operationalisation in tests and assessment…

The present research examines the mechanisms underlying the comprehension of focus alternatives. In particular, we investigate whether listeners determine alternatives based on general semantic priming mechanisms or whether they only consider contrastive alternatives, elements that can replace the expression in focus. In a probe recognition…

Previous research has suggested that some discourse relations are easier to convey implicitly than others due to cognitive biases in the interpretation of discourse. In this article we argue that relations involving a perspective shift, such as confirmation relations, are difficult to convey implicitly. We assess this claim with two empirical…

Advances in natural language processing (NLP) and automatic speech recognition and processing technologies offer new opportunities for language testing. Despite their potential uses on a range of language test item types, relatively little work has been done in this area, and it is therefore not well understood by test developers, researchers or…

Two experiments examined the restriction of referential domains during unscripted conversation by analyzing the modification and online interpretation of referring expressions. Experiment 1 demonstrated that from the earliest moments of processing, addressees interpreted referring expressions with respect to referential domains constrained by the…

Adult native speakers (L1) of Russian and advanced nonnative second-language (L2) speakers read Russian sentences on a computer and were asked to choose one of two inflected past-tense verbs in a forced-choice task. Verbs either matched or mismatched gender of the subject-noun phrase. Data suggested that L1 and L2 speakers may depend on common…

The aim of this study was to find ways to improve online reading and vocabulary learning. Various new types of online reading comprehension and vocabulary development programs and tests were compared in this study to consider how useful they may be for guiding individual or classroom L2 vocabulary instruction. It explored how these programs seek…
