The present study examines the mechanisms of lexical case acquisition in Russian by two-to-five-year-old Russian monolingual (n = 54) and Russian-English bilingual children (n = 38). Participants performed a picture-based sentence completion task. Sentences were constructed to elicit production of real Russian words (n = 24) and nonce words (n =…

Within the same learning context, learners' outcomes in terms of oral fluency vary greatly. This study tracked the relative contributions that first language (L1) and initial second language (L2) fluency skill and working memory (WM) made to L2 fluency development. We assessed the performance of French-speaking Grade 6 learners' (n = 47, mean age:…

Previous studies independently demonstrated impairments in rapid orienting/disengagement and zooming-out of spatial attention in autism spectrum disorder (ASD). These attentional mechanisms, however, are not completely independent. Aiming at a more complete picture of spatial attention deficits in ASD, we examined the relationship between…

When speakers coordinate with one another, they have available a range of alternatives for conceptualizing and describing spatial relationships. To understand the features of successful communication in collaborative spatial tasks, it is important to identify factors that shape speakers' linguistic choices and evaluate them in relation to task…

The learned predictiveness effect or LPE is the finding that when people learn that certain cues are reliable predictors of an outcome in an initial stage of training (phase 1), they exhibit a learning bias in favor of these cues in a subsequent training involving new outcomes (phase 2) despite all cues being equally reliable in phase 2. In…

This article investigates how children leverage intonational and gestural cues to an individual's belief state through unimodal (intonation-only or facial gesture-only) and multimodal (intonation + facial gesture) cues. A total of 187 preschoolers (ages 3-5) participated in a disbelief comprehension task and were assessed for Theory of Mind (ToM)…

In an intelligent tutoring system (ITS), it can be useful to know when a student has disengaged from a task and might benefit from a particular intervention. However, predicting disengagement on a trial-by-trial basis is a challenging problem, particularly in complex cognitive domains. In the present work, data-driven methods were used to address…

Purpose: This study investigates the effects of left- and right-hemisphere damage (LHD and RHD) on the production of idiomatic or literal expressions utilizing acoustic analyses. Method: Twenty-one native speakers of Korean with LHD or RHD and in a healthy control (HC) group produced 6 ditropically ambiguous (idiomatic or literal) sentences in 2…

The purpose of this study was to evaluate the effects of a system of least prompts procedure with a video prompt serving as the model in teaching office tasks to three high school students with moderate intellectual disability. A multiple probe across behaviors design replicated across participants was used to evaluate the intervention. The…

Studies consistently show that Catholic schools produce positive impacts on educational outcomes. Many charter school networks in the United States now provide, what are essentially, secularized versions of the Catholic education model. However, charter schools cannot legally replicate the overt religious curriculum and mission of Catholic…
