Neurosurgical treatment for addiction: lessons from an untold story in China and a path forward

Addiction is a major public-health crisis associated with significant disability and mortality. Although various pharmacological and behavioral treatments are currently available, the clinical efficacy of these treatments is limited. Given this situation, there is a growing interest in finding an effective neurosurgical treatment for addiction. First, we discuss the use of ablative surgery in treating addiction. We focus on the rise and fall of nucleus accumbens ablation for addiction in China. Subsequently, we review recent studies that have explored the efficacy and safety of deep-brain-stimulation treatment for addiction. We conclude that neurosurgical procedures, particularly deep-brain stimulation, have a potentially valuable role in the management of otherwise intractable addictive disorders. Larger well-controlled clinical trials, however, are needed to assess clinical efficacy and safety. We end by discussing several key issues involved in this clinical field and identifying some areas of progress.     

Growth in emotion understanding across early childhood: A cohort-sequential model of firstborn children across the transition to siblinghood

Emotion understanding develops rapidly in early childhood. Firstborn children (N = 231, 55% girls/45% boys, 86% White, 5% Black, 3% Asian, 4% Latinx, M_age = 29.92 months) were recruited into a longitudinal study from 2004 to 2008 in the United States and administered a series of tasks assessing eight components of young children's emotion understanding from ages 1 to 5. Cohort sequential analysis across three cohorts (1-, 2-, and 3-year-olds) demonstrated a progression of children's emotion understanding from basic emotion identification to an understanding of false-belief emotions, even after controlling for children's verbal ability. Emotion understanding scores were related to children's theory of mind and parent reports of empathy, but not emotional reactivity, providing evidence of both convergent and discriminant validity.     

Latino Maternal Literacy Beliefs and Practices Mediating Socioeconomic Status and Maternal Education Effects in Predicting Child Receptive Vocabulary

Research Findings: This study investigated the association between Mexican American maternal education and socioeconomic status (SES) and child vocabulary as mediated by parental reading beliefs, home literacy environment (HLE), and parent–child shared reading frequency. As part of a larger study, maternal reports of education level, SES, HLE, and reading beliefs along with child expressive and receptive vocabulary were collected for 252 mothers and their preschool children from 2 demographically similar school districts in 1 county. Correlations were moderate and positive, with higher levels of maternal education related to family income, HLE, book availability, and children’s expressive and receptive vocabulary. Consistent with long-standing evidence, maternal education and SES were predictors of children’s vocabulary, albeit indirectly through maternal reading beliefs, HLE, and reading frequency. Practice or Policy: Findings extend current knowledge about specific pathways through which social class variables impact children’s language. Policy implications, directions for future research, and study limitations are noted.     

Advances in the Science of Assessment

Designing, developing, and administering assessments has remained fairly unchanged across the past century. However, recent developments in instructional technology, learning science theory, and advances in the design of assessments necessitate a newfound perspective on assessment. The objective of the present article is to review the topic of assessment in depth—past, present, and future. Specifically, we focus on the use of technologically rich learning environments that have spurred advances in student assessment, new methods and procedures from these advances, and consequently the need to consider implementing comprehensive assessment systems that provide rigorous and ubiquitous measurement of the whole student learning experience.
