This study examined the group and individual part score profiles of individuals with mild intellectual disability (ID) who participated in a clinical validity study supporting the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) and a comparison group without ID derived from the WISC-V norming sample. Descriptive analyses revealed…

With just one exception, all of the volumes in Terman's Genetic Studies of Genius report the results of a longitudinal study of more than a thousand intellectually gifted children. That single exception is Volume II, Cox's single-authored "The Early Mental Traits of Three Hundred Geniuses," which instead was a retrospective study of 301…

Prior research suggests that Black children are at risk for delays in diagnosis of autism, but factors that influence diagnostic timing across races remain unclear. This study analyzed data from Black and White children who received a first-time autism diagnosis at a specialty clinic. Black youth were under-represented in the group who received a…

The purpose of this paper is to explore the factor structure of the Wechsler Intelligence Scale for Children--Fifth edition (WISC-V). As such, this is the first study that will examine the factor structure of the WISC-V in a non-standardization sample of Black children. Utilizing confirmatory and exploratory factor analytic techniques in AMOS our…

Pew Research Center conducted this study to understand how parents of kids ages 12 and younger approach their children's technology use and screen time. For this analysis, 3,054 parents who have children ages 12 and under were surveyed from May 13 to 26, 2025. The sample for this survey includes respondents from two different sources--Pew Research…

Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10 subtest primary battery was evaluated across sex, age (6-8, 9-11, 12-14, and 15-16 year-olds), and three diagnostic (attention-deficit/hyperactivity disorder, anxiety, and encephalopathy) groups within a large clinical sample (N = 5359) referred to a…

Academic acceleration, which enhances challenges for academically gifted students, can be subject-based or whole-grade. Limited research has explored its application in the twice-exceptional population, where students possess notable cognitive strengths and challenges due to psychological diagnoses. Our clinical study investigates the likelihood…

The purpose of this study is to examine the bidirectional relationship between children's language development and challenging behaviors as well as the moderating roles of gender and race/ethnicity. We conducted a number of structural equation modeling analyses with a national representative sample (N = 2,462) of Head Start children from the 2014…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

There is significant debate over the value and ethics of IQ testing for children, including those from diverse cultural groups, particularly in light of studies examining performance on various subtests that are uncovering important processing differences between cultural and linguistic groups (Sotelo-Dynega, Ortiz, Flanagan, & Chaplin, 2013).…

Research Findings: This study examines efforts by Head Start programs to coordinate with elementary schools and seeks to better understand how coordination practices may support children's transition to and success in kindergarten. Data were drawn from a nationally representative sample of Head Start children (N = 2,019) followed through…

Research Findings: Home language and literacy inputs have been consistently linked with enhanced language and literacy skills among children. Most studies have focused on maternal inputs among monolingual populations. Though the proportion of American children growing up in primarily non-English-speaking homes is growing and the role of fathers in…

A high-quality estimate of the mean IQ of a country requires giving a well-validated test to a nationally representative sample, which usually is not feasible in developing countries. So, we used a convenience sample and four corrections based on theory and empirical findings to arrive at a good-quality estimate of the mean IQ in Bali. Our study…

This descriptive study examines the complexity of psychiatric comorbidity in treatment-seeking youth with ASD and anxiety symptoms. Forty-two parents of youth with ASD and anxiety (ages 8-14) completed a structured diagnostic interview (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version). Youth…

There is a virtual consensus regarding the types of language processes, interactions, and material supports that are central for young children to become proficient readers and writers (Shanahan et al., 2008). In this study, we examine these supports in both home and school contexts during children's critical transitional kindergarten year.…
