In this article, we present an approach to the automatic correction of preposition errors in L2 English. Our system, based on a maximum entropy classifier, achieves average precision of 42% and recall of 35% on this task. The discussion of results obtained on correct and incorrect data aims to establish what characteristics of L2 writing prove…

This research explores learner-learner interactions (n = 18) in an authentic EFL classroom. First, we examined the nature of interactional feedback provided during two decision-making tasks. We then investigated whether the learners had made use of the feedback by looking at whether (and if so, how) they had modified their output immediately after…

Preschoolers' theory of mind (ToM) was examined in relation to emotional features of their conflicts with siblings, using mothers as privileged informants. Fifty-four children aged 3 to 5 years and their 54 mothers took part. Children were given 10 standard false belief tasks and a standardized language test. Mothers completed questionnaires,…

This study investigated differences in attention and learning among Guatemalan Mayan and European American children, ages 5-11 years, who were present but not addressed while their sibling was shown how to construct a novel toy. Each child waited with a distracter toy for her or his turn to make a different toy. Nonaddressed children from Mayan…

Language samples elicited through a picture description task were recorded from 38 adolescents and adults with Williams syndrome (WS) and one control group matched on age, and another matched on age, IQ, and vocabulary knowledge. The samples were coded for use of various types of inferences, dramatic devices, and verbal fillers; acoustic analyses…

Two experiments examined whether text composition engages verbal, visual, and spatial working memory to different degrees. In Experiment 1, undergraduate students composed by longhand a persuasive text while performing a verbal, visual, or spatial concurrent task that was presented visually. In Experiment 2, participants performed a verbal or…

Many students identified with emotional or behavioral disorders have social skill deficits, often displayed as less mature or inappropriate social behavior. Students may have difficulty engaging in appropriate play or social interactions and may at times become aggressive. The inability to interact with others has a negative impact on academic…

Recent psychological and neuropsychological research suggests that executive functions--the cognitive control processes that regulate thought and action--are multifaceted and that different types of executive functions are correlated but separable. The present multivariate twin study of 3 executive functions (inhibiting dominant responses,…

This study draws on sociocultural theory to explore how adult ESL learners interact with either a higher- or a lower-proficiency peer during pair problem solving, and how they each perceive the interactions with their partners. Three ESL learners engaged in a three-stage task: pair writing; pair noticing; and individual writing with two learners,…

This study examined the relative contributions of emotion knowledge and teacher-child relational variables to school competence. Seventy-four economically and ethnically diverse preschoolers (40 boys, 34 girls) completed an emotion knowledge task and a standardized school competence measure. Classroom teachers and their assistants rated the…

The authors tested the hypothesis that a match between the gender relevance of a stressor and one's sex or gender role identification would elicit higher cardiovascular responses. Healthy female and male undergraduates (n = 108) were exposed to two stressors: the Cold Pressor Test (CPT) and the n-back task. Stressor relevance was manipulated to be…

Drawing on the psycholinguistic rationale and empirical research on output (e.g., [Izumi, S., 2002. "Output, input enhancement, and the noticing hypothesis: An experimental study on ESL relativization." "Studies in Second Language Acquisition" 24, 541-577; Izumi, S., Bigelow, M., 2000. "Does output promote noticing and second language…

This classroom-based study investigated the metatalk of learners working in pairs on a text reconstruction task. Specifically, the study investigated the learners' level of engagement with linguistic choices, and whether the level of engagement affected subsequent language development. Data were collected over a 2-week period. In the first week,…

In this paper, we describe an initial exploratory study designed to compare the outcomes of online listening and online text-based tasks in the context of the study of Italian at The University of Melbourne. Our findings allow us to characterise online listening and online reading as a qualitative difference between deep and surface approaches to…

Purpose: The purposes of this study were (a) to identify cognitive abilities and other factors related to successful completion of training for computer-based tasks that simulated real jobs and (b) to create a brief assessment battery useful in assessing older adults for these kinds of jobs. Design and Methods: Participants from three age groups…
