Iconic words imitate their meanings. Previous work has demonstrated that iconic words are more common in infants' early speech, and in adults' child-directed speech (e.g., Perry et al., 2015; 2018). This is consistent with the proposal that iconicity provides a benefit to word learning. Here we explored iconicity in four diverse language…

An insight regarding few of the experiences during video games playing activity is still fuzzy. This paper presents an extensive empirical study that analyzes the experiences of 100 participants (i.e. 25 children, younger adults, older adults, and elders each) during brain games play. This concludes a number of significant correlations among the…

Over the past decade or so, developments in language comprehension research in the domain of cognitive aging have converged on support for resilience in older adults with regard to situation model updating when reading texts. Several studies have shown that even though age-related declines in language comprehension appear at the level of the…

This paper aims at connecting Self-Determination Theory (SDT) with research on moral identity. It is argued that SDT provides a unique and integrative framework for addressing important questions that have guided research on moral identity for many years: What is a moral identity? How is it linked to moral action? How do moral identities develop?…

Using public information from birth certificates and prison records from Florida, we adopt a reduced-form approach to estimate the effect of relative age on the probability of incarceration in adulthood (until age 30-40). We use a Regression Discontinuity Design around the cutoff date for Kindergarten enrollment (Sept. 1). We find strong evidence…

This study examined whether the proposed bilingual advantage in inhibitory control and working memory can be extended to a trilingual advantage, and assessed any age-related effects on a continuum in young adults to older adults. Trilinguals, bilinguals and monolinguals' performance on the Simon task and a numerical version of the N-back task was…

This occasional paper presents subgroup findings from the Monitoring the Future (MTF) study on levels of, and trends in, the use of a number of substances for nationally representative samples of high school graduates ages 19-30, "Monitoring the Future National Survey Results on Drug Use, 1975-2018.

The Youth Transition Report presents data that underscore the gap between youth with disabilities and those without disabilities on measures of success in education and employment. While other reports present information about the working-age adult population and children with disabilities, there are no reports that specifically focus on the youth…

The COVID-19 pandemic has raised huge concerns for the mental health of an entire generation of children. But the pandemic may represent only the tip of a mental health iceberg -- an iceberg we have ignored for far too long. For the first time, "The State of the World's Children" examines the mental health of children and adolescents.…

To learn about whether young adults with intellectual disabilities in the vocational rehabilitation (VR) program are getting work experience, the authors of this Data Note examined the age at application of people with intellectual disabilities who exited the VR program in 2012. Findings show the largest age group at application was people who…

The present article responds to Males and Brown's "Teenagers' High Arrest Rates: Features of Young Age or Youth Poverty?" which claims that the widely observed pattern of crime rates peaking in late adolescence or early adulthood is an artifact of age differences in poverty. We note that the authors' interpretation of their aggregated…

On February 17, 2014, Dr. Jonathan Perry, former director of counseling at the University of Arkansas, sparked a lively debate on the listserv of the Association of University and College Counseling Center Directors (AUCCCD) by warning about the likelihood and dangers of underdiagnosing borderline II disorder. Standing out among the many…

"Language awareness and language aptitude" often crop up in discussion of various second language acquisition phenomena, including age-related phenomena. There is a troublesome and ongoing definitional and theoretical problem in this connection: Different researchers have different perspectives on what is to be included in the respective…

Although previous research documents high rates of child abuse, street victimization, and substance use among homeless youth, few studies have investigated these three constructs simultaneously, and thus little is known about how various forms of victimization are uniquely associated with substance use among this population. The purpose of this…
