The current study examined the incremental validity of the Luria interpretive scheme for the Kaufman Assessment Battery for Children-Second Edition (KABC-II) for predicting scores on the Kaufman Test of Educational Achievement-Second Edition (KTEA-II). All participants were children and adolescents (N = 2,025) drawn from the nationally…

Purpose: This study used a computational vocal tract model to investigate the relationship of diphthong duration and vocal tract movement magnitude to measures of the F2 trajectory in CV words. Method: Three words ("bough," "boy," and "buy") were simulated on the basis of an adult female vocal tract model, in which…

Purpose: The study examined whether semantic and phonological encoding processes were capacity demanding, involving the central cognitive mechanism, in adults who do and do not stutter (AWS and NS) to better understand the role of cognitive demand in linguistic processing and stuttering. We asked (a) whether the two linguistic processes in AWS are…

It is known that, on average, people adapt their choice of memory strategy to the subjective utility of interaction. What is not known is whether an individual's choices are "boundedly optimal." Two experiments are reported that test the hypothesis that an individual's decisions about the distribution of remembering between internal and…

Psychological testing can serve as a prototype on which to base a data-generated approach to instructional design. In "testing batteries" tests are used to predict achievement. In the proposed approach batteries of prescriptions would be used to produce achievement. In creating "test batteries" tests are selected for their…

We compared the ability of three different contextual models of lexical semantic memory (BEAGLE, Latent Semantic Analysis, and the Topic model) and of a simple associative model (POC) to predict the properties of semantic networks derived from word association norms. None of the semantic models were able to accurately predict all of the network…

This study examined the relationship among resilience, coping styles, and subjective well-being (SWB) among 239 Chinese university students, with a focus on the mediating role of coping styles in the relationship between resilience and SWB and the moderating function of resilience in the prediction of SWB from coping styles. Results of latent…

Environmental stewardship is an underlying theme in outdoor education (OE) and environmental education (EE), but maintaining natural areas in a sustainable balance between conservation and preservation requires knowledge about how natural areas respond to anthropogenic disturbance. My five-part study investigated the effects of disturbance on…

Estimating student proficiency is an important task for computer based learning systems. We compare a family of IRT-based proficiency estimation methods to Deep Knowledge Tracing (DKT), a recently proposed recurrent neural network model with promising initial results. We evaluate how well each model predicts a student's future response given…

Research in literature reports the importance of L2 vocabulary and syntactic knowledge on the learners' reading comprehension. In this regard, the current study investigated the role of vocabulary knowledge that is disunited into depth and breadth dimensions and syntactic knowledge in the reading comprehension scores of an advanced cohort of…

A significant amount of research effort has been put into finding variables that can identify students at risk based on activity records available in learning management systems (LMS). These variables often depend on the context, for example, the course structure, how the activities are assessed or whether the course is entirely online or a…

Researchers studying parent-child reminiscing in the preschool years have often focused on parents' and children's elaborative talk (i.e., provision of unique details). The current study proposes a novel conceptualization of parent-child reminiscing narratives by examining 4 levels of abstraction (i.e., a continuum of literal to inferential…

Children with autism spectrum disorder (ASD) vary greatly in social functioning, and in turn, long-term relational and academic outcomes. Responsive parenting which follows a child's lead and focus of attention is predictive of language and social gains for children with or without developmental risk. The present study prospectively assessed 176…

To draw informed conclusions from research studies, research consumers need full and accurate descriptions of study methods and procedures. Preregistration has been proposed as a means to clarify reporting of research methods and procedures, with the goal of reducing bias in research. However, preregistration has been applied primarily to research…

New approaches to support the early learning for young Indigenous children are important to government policies across Australia. This study explores whether the Abecedarian Approach Australia (3a) intervention, with strong cultural adaptations, can boost young Aboriginal children's early language and learning skills, prior to preschool.…
