The current study examined parental advice given to fourth‐ and fifth‐grade preadolescents who imagined being bystanders to different forms of bullying (physical, verbal, property attack, social manipulation, exclusion). We assessed the frequency with which parents advised youth to follow specific intervention strategies (stop the bully, help/comfort the victim, tell adults), and we tested whether the frequency by which parents provided each kind of advice varied by the form of bullying described. One hundred and six fourth‐ and fifth‐grade preadolescents completed an interaction in which their parent gave them advice about how to respond if they were bystanders to five hypothetical bullying situations. Each situation described a different form of bullying. Across forms of bullying, parents most frequently told bystander children to intervene by telling an adult. However, advice differed based on the form of bullying presented. Parents most frequently advised children to “tell an adult” in response to physical bullying or property attacks, most frequently advised children to “help/comfort victims” in response to social exclusion and physical attacks, and most frequently advised children to “stop the bully” in response to verbal and social manipulation bullying. 相似文献

The idea that language skills support school readiness, predicting later self‐regulation and academic success, is widely accepted. Although vocabulary is often emphasized in the developmental literature, the ability to use language appropriately in the classroom, or social communication skills, may also be critical. This article examined longitudinal contributions of children's vocabulary and social communication skills, from preschool to kindergarten, to kindergarten academic achievement (reading and math) and self‐regulation (executive functions and learning behaviors). Participants were 164 children (14% Latinx, 30% Black, 56% White; 57% girls) enrolled in Head Start programs. Results revealed that initial levels and growth in vocabulary and communication skills predicted better academic achievement. Social communication skills uniquely predicted self‐regulation, after accounting for vocabulary. We discuss potential mechanisms for these links and recommend that strategies to build social communication skills be incorporated in preschool interventions promoting school readiness. 相似文献
