To investigate how task complexity cognitive factors influence the lexical complexity in essay writing, this study was guided by Robinson's Cognition Hypothesis (CH) and Skehan's Limited Attentional Capacity Model (LACM), and examined the effects of task complexity on lexical complexity in undergraduates' essay writing. Using Lu's Lexical…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

In recent years, several studies have provided evidence for the positive impact of augmented reality in language acquisition. In particular, augmented reality as a multimedia learning environment has been found to be potentially more effective than learning using traditional methods, such as paper-based textbooks. According to the cognitive theory…

Referential gaze has been shown to benefit language processing in situated communication in terms of shifting visual attention and leading to shorter reaction times on subsequent tasks. The present study simultaneously assessed both visual attention and, importantly, the immediate cognitive load induced at different stages of sentence processing.…

Across education, certification and licensure, there are repeated calls for the development of assessments that target "higher-order thinking," as opposed to mere recall of facts. A common assumption is that this necessitates the use of constructed response or essay-style test questions; however, empirical evidence suggests that this may…

Since the mid-1990s, the link between recasts and L2 development has been extensively tested, and the results from those studies have largely demonstrated that recasts have a positive effect on L2 learning. With this firm support from previous empirical evidence, studies have begun to focus on how recasts assist learning and under what conditions…

This study examined the role of learners' perceptions in a learner-controlled computer-based learning environment. Computer-based learning environments that offer learner control (LC) to the learners are assumed to enhance motivation and learning outcomes. Recently, the focus of LC research has shifted from measuring the direct effect of LC on…

The present study adopted a cognitive linguistic framework--Talmy's (1985, 1991, 2000) typological classification of motion events--to investigate how second-language (L2) Chinese learners come to express motion events in a targetlike manner. Fifty-five U.S. university students and 20 native speakers of Chinese participated in the study. A…

Two experiments tested the Conceptual Dependency Theory, stating that verbs are represented in memory as combinations of actions and relations encoding underlying conceptual structure. Experiment I results supported the conceptual complexity hypothesis, while II rejected complexity for imagery as the predictor of performance. (CHK)
