Conditional cash transfers (CCTs) are used to reduce poverty while incentivizing investments in children. Targeting CCTs to certain groups of children can improve efficiency, but positive effects on eligible children may be offset by reductions in investments for ineligible siblings. Using data from Nicaragua, we estimate program effects on…

The longitudinal relationship between attention deficit hyperactivity disorder (ADHD) and violent criminality has been extensively documented, while long-term effects of autism spectrum disorders (ASDs), tic disorders (TDs), and obsessive compulsive disorder (OCD) on criminality have been scarcely studied. Using population-based registers of all…

Vitamin D deficiency has been proposed as a possible risk factor for developing autism spectrum disorder (ASD). 25-Hydroxyvitamin D3 (25(OH)D3) levels were examined in a cross-sectional population-based study in the Faroe Islands. The case group consisting of a total population cohort of 40 individuals with ASD (aged 15-24 years) had significantly…

Research on family background and educational success focuses almost exclusively on two generations: parents and children. This study argues that the extended family contributes significantly to the total effect of family background on educational success. Analyses using the Wisconsin Longitudinal Study show that, net of family factors shared by…

Reading performance data from 254 pairs of identical (MZ) and 420 pairs of fraternal (DZ) twins, 8.0 to 20.0 years of age, were subjected to multiple regression analyses. An extension of the DeFries-Fulker (DF) analysis (DeFries & Fulker, 1985, 1988) that facilitated inclusion of data from 303 of their nontwin siblings was employed. In addition to…

This study aimed to investigate the presence of an own-age bias in young children who accumulated different amounts of early experience with child faces. Discrimination abilities for upright and inverted adult and child faces were tested using a delayed two-alternative, forced-choice matching-to-sample task in two groups of 3-year-old children,…

We examined whether infants' preference for speech at 12 months is associated with autistic-like behaviors at 18 months in infants who are at increased risk for autism spectrum disorder (ASD) because they have an older sibling diagnosed with ASD and in low-risk infants. Only low-risk infants listened significantly longer to speech than to…

Self-representations play an important role in adolescent development. This study compared self-representations for siblings and explored whether sibling relationship characteristics are associated with similarities or differences in sibling self-concepts. We examined self-representations of 438 adolescent sibling dyads (M age younger sibling =…

This study explored the experiences of 2 young people with intellectual disability during launching into individual supported living, including the impact of a Western Australian (WA) funding approach. Method: Two case studies…

The famous Polgar sisters started chess very young, undertook extensive study, and two became grandmasters. This case often is cited as decisive evidence that practice alone is key in development of expertise, that innate talent is unimportant or non-existent, and that almost anyone can become a grandmaster. But on close examination these claims…

The deinstitutionalization movement that began 50 years ago remains a current issue for professionals and families. Using qualitative phenomenology methodology, we investigated the experience of mandated deinstitutionalization for parents and siblings whose relatives with intellectual and developmental disabilities (IDD) transitioned from…
