The particular influence associated with framework position together with dosage settlement around the quality of single chemical reconstructions.
Targeting these mechanisms could be important for effective intervention. The papers further explore factors that might mitigate or amplify the association between parental and offspring use of cannabis, such as active coping or harsh parenting. Finally, to ensure bridging between substance abuse epidemiology and intervention research, this article considers research training practices.

Study teams recruited youth in Iowa, Washington, Oregon, New York, and Arizona in the 1980s-1990s, assessed them into adulthood, and recruited their partners and offspring for another study. All of the studies assessed substance use in 2 or more generations. Other strengths in this section include the strong representation of fathers, the demographic diversity of the samples as a whole, and the demonstrations of varied statistical and replication approaches. The findings highlight features of parental histories of cannabis use during adolescence that are associated with their children's risk for cannabis use and factors that explain or weaken intergenerational similarities. Two groups of prevention scholars also offered commentaries on the implications of these studies for prevention and training, and collaboration. It is hoped that the Special Section will stimulate new hypotheses, replications, and communication among etiological and prevention researchers. Furthermore, the papers highlight that the familial transmission of substance use risk should be taken into account more fully in the design of prevention programs to maximize impacts for youth as well as their future offspring.

We developed a theory informed by these perspectives that explains how institutional contexts affect emerging adults' success in transitioning to and progressing through college. We theorize that institutional contexts increase individuals' probability of attaining specific goals when they provide stronger channels that offer more versus fewer structural supports for these goals. Moreover, we theorize, these institutional channels influence which individual differences, including belonging certainty, growth mindset of intelligence, and grit, will be useful in goal pursuit, above and beyond individuals' academic preparation and demographic factors. We examined postsecondary goal pursuit over a 6-year period among 1,850 students who attended one of four district high schools in Pennsylvania or Massachusetts. On average, they began the study at 17.91 years of age; 48% were male, 43% belonged to a historically marginalized ethnicity, and 56% had free or reduced lunch status. We found that channel strength and psychological factors interacted in ways predicted by our theory. Higher belonging certainty and growth mindset in Grade 12, which encourage a focus on process and progress, predicted better outcomes in weaker postsecondary channels, especially college enrollment and on-track progress. Higher grit, which encourages a commitment to goal attainment, predicted better outcomes in stronger postsecondary channels, especially on-time graduation. The study locates the importance of psychological factors in predicting goal attainment in different-strength institutional channels during emerging adulthood.

We studied children 6-8 and 10-14 years old and college students (in all, 104 women and 76 men; 3% Hispanic, 3% Black or African American, 3% Asian, 7% multiracial, and 84% White). On each dual-task trial, the participant received an array of colored squares to be retained for a subsequent probe recognition test and then an easy or more difficult signal requiring a quick response (a speeded task, clicking a key on the same side of the screen as the signal or the opposite side). Finally, each trial ended with the presentation of the array item recognition probe and the participant's response to it. TPEN cost In our youngest age group (6-8 years), array memory was often displaced by the speeded task performed under load, especially when it was the opposite-side task, but speeded-task accuracies were unaffected by the presence of an array memory load. In contrast, in older participants (10-14 years and college students), the memory load was maintained better, with some cost to the speeded task. With maturity, participants were better able to adopt a proactive stance in which not only present processing demands but also upcoming demands were taken into account, allowing them to balance the demands of the two tasks.

The present study investigated infants' sensitivity to these contrasts in a habituation-based discrimination and word learning task (total N = 168, 78 males and 90 females). All infants were native to Singapore and were of Chinese origin. Family socioeconomic status (SES) was measured by parental education. The mean number of years of parental education was 4.02 years after high school. Using a habituation-based discrimination paradigm, monolingual, and bilingual infants' sensitivity to the Hindi dental/retroflex voiceless stop was investigated at 14 months (Experiment 1). Neither group discriminated the contrast. Using the Switch paradigm, we assessed sensitivity to the same contrast in a word learning task. Monolingual and bilingual infants were tested at 14- and 19 months (Experiment 2a) and subsequently, an older group of bilingual infants was tested at 24 months (Experiment 2b).
