The New Jersey Graduated Driver License (GDL) restrictions were updated in 2010 with changes that included a more active role of parents monitoring practice driving with their teens. In addition to extending the driving phases, there were new curfew and passenger limit restrictions. Teen drivers were also required to use red decals on license plates to identify themselves as inexperienced drivers. The Division of Highway Traffic Safety had partnered with the Motor Vehicle Commission in the past to produce practice driving guides for parents of teen drivers, but recognized the need to support this type of informational campaign with an educational program for helping parents to understand changes in the GDL and recognize the importance of their role in the GDL monitoring process. In 2010, the New Jersey Parent/Teen Driver Orientation program was developed to educate parents of teen drivers on the new GDL restrictions and Children’s Hospital of Philadelphia (CHOP) findings concerning the importance of parenting roles in teen driver safety. Additional resources were incorporated into the orientation that included the Centers for Disease Control (CDC) community based information and the University of Michigan Transportation Research Institute (UMTRI) parent-teen driver contracts.This community-based training, known as the New Jersey Parent/Teen Driver Orientation was later renamed Share the Keys, and had been developed for the state as a component of the New Jersey Highway Safety grant received by Kean University. The comprehensive program was designed to engage parents, teens, educators, and law enforcement in the teen driving process and help parents to understand how personal parenting styles and engagement may impact teen crash risk and compliance with the GDL restrictions. Local representatives from traffic safety and law enforcement teamed with school officials and driver education teachers to present programs in their communities. The evaluation process was built into the program as a pre-survey administered at the beginning of the session, a post-survey completed directly afterward, and a voluntary follow-up survey completed on line or mailed, beginning six months later.Evidence from the first year showed that parents maintained a significant level of engagement throughout the GDL process with their teen drivers. However, findings did establish the need to further examine why Authoritative parenting styles had declined, especially since this parenting approach was considered in the literature as most effective in reducing teen crash risks. Therefore, the scope of this study was broadened to a three year effort that reached over 2800 parents and investigated behavioral outcomes impacted by Share the Keys. While comparisons made between driving phases and parenting styles had yielded no significant results, changes within parenting style scores were shown to be effective over time. The reported levels of Permissive and Uninvolved parents remained consistent throughout all three driving phases, while Authoritarian parenting peaked during the Probationary phase, and Authoritative parenting was noted as highest once teens earned their license.  相似文献

When we dream, it is often assumed, we are isolated from the external environment. It is also commonly believed that dreams can be, at times, accurate, convincing replicas of waking experience. Here I analyse some of the implications of this view for an enactive theory of conscious experience. If dreams are, as described by the received view, “inactive”, or “cranially envatted” whilst replicating the experience of being awake, this would be problematic for certain extended conscious mind theories. Focusing specifically on Alva Noë’s enactive view, according to which the vehicles of perceptual experience extend beyond the brain, I argue that dreams are a quandary. Noë’s view is that dreaming is consistent with enactivism because even if dreams are inactive and shut off from the external environment, they are not “full-blown” perceptual consciousness, and also, there is some reason to reject the inactive claim. However, this view rests on an unjustified and reductive account of dreams which is not supported by empirical evidence. Dreams can indeed replicate waking phenomenal experience during inactive periods of sleep, and we have no reason to suspect that dreams which are more inactive are less “full-blown”. Taken together, this shows that dreams are indeed relevant to extended conscious mind theories and need to be taken into account by enactivists.  相似文献

本研究拟考察发展性计算障碍儿童的认知缺陷成因。实验1要求被试在三种形式(点/点,数/数,点/数)下进行数量比较,实验2仅将点集替换为汉字数字词。结果表明障碍组和正常组在数/数、点/数和汉字/汉字比较任务上的成绩存在显著差异,而在点/点和汉字/汉字比较上没有差异。据此推论,计算障碍儿童符号加工能力受到损伤,符号与非符号数量转换能力存在缺陷,但非符号加工能力和不同符号间数量转换没有缺陷,支持语义提取缺陷假设。  相似文献

采用事件相关电位,运用无启动的同一字判断(靶字延迟反应)范式,以大学生为被试探讨汉字刺激质量和频率是否具有交互作用。行为结果显示,刺激质量和频率在反应时上存在交互作用。脑电结果显示,重度模糊诱发了更大的N250和N400,且刺激质量和频率在N400上存在交互作用。结论是,汉字刺激质量和频率在反应时和N400上存在交互作用,表明在汉字识别中存在串级加工,支持IA模型。  相似文献

为探讨社会排斥和社会接纳情境下儿童奖惩分配公平性,研究采用个体-偶然排斥范式和第三方奖惩分配范式,对8~9岁儿童奖惩分配公平性行为和奖惩分配公平性判断进行研究,结果发现:(1)社会排斥组被试的奖惩分配公平性行为显著多于社会接纳组,奖惩分配不公平性行为显著少于社会接纳组。9岁组被试的奖惩分配公平性行为显著多于8岁组,奖惩分配不公平性行为显著少于8岁组;(2)社会排斥组被试的奖惩分配公平性判断显著高于社会接纳组,9岁组被试的奖惩分配公平性判断显著高于8岁组,奖惩分配不公平性判断显著低于8岁组。结论:社会情境影响儿童的奖惩分配公平性,在排斥情境下,8~9岁儿童的奖惩分配公平性明显提升;8~9岁儿童的奖惩分配公平性随年龄增长有上升趋势。  相似文献

为探讨小学生在交通情境中的视觉搜索发展特点,研究以一、二、四和六年级小学生,以及成人为被试,采用“找不同”任务和过马路决策眼动任务进行实验。结果发现,一、二年级小学生“找不同”的效率低于成人;一年级小学生冒险及错失过马路比例均较高;小学生的眼跳特征与成人相似,但对兴趣区的关注低于成人;女生错失过马路比例高于男生,视觉搜索水平及搜索策略的性别差异不显著。研究表明,小学生的视觉搜索能力随年龄逐渐提高,但搜索的有效性低于成人,性别分化不明显。  相似文献

This study focuses on the reliability and validation of the Chinese version of the Moral Attentiveness Scale. Factor analysis confirmed that the scale includes two factors: perceptual moral attentiveness and reflective moral attentiveness. Moral attentiveness is negatively correlated with normlessness and positively associated with internalization and symbolization, moral identity, and other academic dishonesty behaviors. Reflective moral attentiveness moderated the relationship between formalism and unethical decision making. All results showed that the Chinese version of the Moral Attentiveness Scale has satisfactory psychometric properties and is a valid and reliable measurement of moral attentiveness in the Chinese population.  相似文献
