The present study investigates English-learning infants' early understanding of the link between the grammatical category "verb" and the conceptual category "event," and their ability to recruit morphosyntactic information online to learn novel verb meanings. We report two experiments using an infant-controlled…

This article investigates the population heterogeneity of test data for the case of teacher licensure assessments in Saudi Arabia. The results from factor mixture modeling of the data (N = 15,962) on the construct of "promoting learning" revealed the presence of two latent classes of examinees based on their performance profiles across…

Purpose: The purpose of this paper is to study relative age effects (RAEs) in a selected sample of university students. The majority of education systems across the globe adopt age-related cut-off points for eligibility. This strategy has received criticism for (dis)advantaging those older children born closer to the "cut-off" date for…

Early intervention (EI) and early childhood special education (ECSE) practitioners participating in the Child Outcomes Summary (COS) process must understand age-expected development, the ages at which children typically acquire different skills. This resource provides answers to commonly asked questions about age anchoring as it applies to the COS…

This report is the 34th edition of the annual National Deaf-Blind Child Count, the first and longest running count of children who are deaf-blind in the world. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on Deaf-Blindness (NCDB), its predecessors, and state…

Applied linguistics may benefit from a morphological complexity measure to get a better grip on language learning problems and to better understand what kind of typological differences between languages are more important than others in facilitating or impeding adult learning of an additional language. Using speaking proficiency scores of 9,000…

Background: Outcomes for people with an intellectual disability (ID) may differ depending on the severity of the condition. This study evaluated whether a tool used to screen for the presence of ID could also give an early indication of severity, in order to help inform future support needs. Methods: Multicategory receiver operating characteristic…

In response to the articles in this forum, the authors write that they were struck by the way most of the authors assumed that generations are stable entities characterized by readily identifiable factors, such as age, attitudes or circumstances. Following a constitutive philosophy of communication and instruction (Fassett & Warren, 2007;…

Hala, Brown, McKay, and San Juan (2013) found that children as young as 2.5 years of age demonstrated high levels of accuracy when asked to recall whether they or the experimenter had carried out a particular action. In the research reported here, we examined the relation of early-emerging source monitoring to executive function abilities.…

Purpose: The purpose of this study was to test the convergent validity of Omron 306 using Biospace InBody 720. Method: A total of 267 participants (145 boys; aged 10.4-17.9 years) completed testing during a single session. Each measure provided percent body fat (%BF), while the InBody 720 included fat-free mass (FFM). The validity was examined…

Visual appearance is one of the main cues children rely on when categorizing novel objects. In 3 studies, testing 128 3-year-olds and 192 5-year-olds, we investigated how various kinds of information may differentially lead children to overlook visual appearance in their categorization decisions across domains. Participants saw novel animals or…

This report is the 33rd edition of the annual National Child Count of Children and Youth Who Are Deaf-Blind, the first and longest running registry and knowledge base of children who are deaf-blind in the world. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on…

In recently published studies on cyberbullying, students are frequently categorized into distinct (cyber)bully and (cyber)victim clusters based on theoretical assumptions and arbitrary cut-off scores adapted from traditional bullying research. The present study identified involvement classes empirically using latent class analysis (LCA), to…

During their education, students are presented with information across a variety of academic domains. How students ask questions as they learn has implications for understanding, retention, and problem solving. The current research investigates the influence of age and prior knowledge on the ways students approach questioning across history and…

How does cognitive control change with age, and what are the processes underlying these changes? This question has been extensively studied using versions of the task-switching paradigm, which allow participants to actively prepare for the upcoming task (Kray, Eber, & Karbach, 2008). Little is known, however, about age-related changes in this…
