A natural language based system has been used to author and mark short-answer free-text assessment tasks. Students attempt the questions online and are given tailored and relatively detailed feedback on incorrect and incomplete responses, and have the opportunity to repeat the task immediately so as to learn from the feedback provided. The answer…

The research presented in this dissertation examined changes in brain activity associated with learning, forgetting and using a second language. The first experiment investigated the changes that occur when novice adult second language learners acquire and forget second language words. Event-related brain potentials were measured while native…

As a group, children with hearing loss demonstrate delays in language development relative to their peers with normal hearing. Early intervention has a profound impact on language outcomes in children with hearing loss. Data examining the relationship between degree of hearing loss and language outcomes are variable. Two approaches are used in the…

Second language (L2) learners notoriously have trouble using articles in their target languages (e.g., "a", "an", "the" in English). However, researchers disagree about the patterns and causes of these errors. Past studies have found that L2 English learners: (1) Predominantly omit articles (White 2003, Robertson 2000), (2) Overuse "the" (Huebner…

Unlike English, Standard Arabic has two forms of subject pronouns: Independent such as "?na" ("I"), and a pronominal suffix that is an integral part of the verb such as "katab-tu" ("I wrote"). Independent subject pronouns are commonly used in nominal sentences, not verbal sentences. Use of independent…

Computer technology improves the process of SLA by providing access to an ample amount of input within a communicative context in which participants can engage in synchronous and asynchronous conversations (Payne & Whitney, 2002; Sykes, 2005). This research project aims to investigate the role of alignment in learning a second language within the…

Neighborhood density refers to the number of words that sound similar to a given word. Previous studies have found that neighborhood density influences the recognition of spoken words (Luce & Pisoni, 1998); however, this work has focused almost exclusively on monosyllabic words in English. To investigate the effects of neighborhood density on…

This study investigated whether masked priming is mediated by existing memory representations by determining whether nonwords targets would show repetition priming. To avoid the potential confound that nonword repetition priming would be obscured by a familiarity response bias, the standard lexical decision and naming tasks were modified to make…

This article describes an in-class exercise that illustrates the advantage of semantic over nonsemantic study habits. The exercise includes a survey of students' current study strategies, followed by the presentation of an abbreviated version of Craik and Tulving's(1975) classic levels-of-processing experiment. We observed significant benefits of…

Two experiments investigated the mechanism by which listeners adjust their interpretation of accented speech that is similar to a regional dialect of American English. Only a subset of the vowels of English (the front vowels) were shifted during adaptation, which consisted of listening to a 20-min segment of the "Wizard of Oz." Compared…

The cognitive profiles of children with Developmental Reading Disorder (RD) and Attention-Deficit/Hyperactivity Disorders (ADHD) have been extensively studied in alphabetic language communities. Deficits in phonological processing and rapid naming have been implicated as core features of RD although whether the latter is a deficit specific to RD…

This article investigates the effect of age of first exposure and the quantity and quality of input to which non-native acquirers (L2ers) are exposed in their acquisition of grammatical gender in Dutch. Data from 103 English-speaking children, preteens and adults were analyzed for gender agreement on definite determiners. It was observed that…

Previous studies have suggested that previews of words prior to fixation can be processed orthographically, but not semantically, during reading of sentences (K. Rayner, D. A. Balota, & A. Pollatsek, 1986). The present study tested whether semantic processing of previews can occur within words. The preview of the second constituent of…

We have developed a process model that learns in multiple ways while finding faults in a simple control panel device. The model predicts human participants' learning through its own learning. The model's performance was systematically compared to human learning data, including the time course and specific sequence of learned behaviors. These…

With a goal of investigating psycholinguistic bases of spoken word processing in a second language (L2), this study examined L2 learners' sensitivity to phonological information in spoken L2 words as a function of their L2 experience and attentional demands of a learning task. Fifty-two Chinese learners of English who differed in amount of L2…
