Following the release of the first COVID-19 vaccinations many people utilized social media to promote vaccination among their social circles. These attempts to persuade others to get vaccinated ranged from positive encouragement (e.g., emphasizing the prosocial benefits and positive outcomes) to shame and threats (e.g., name calling and threating to end friendships over vaccination status). The present study investigated how these different social media messages affected COVID-19 vaccination intentions. In June 2021, shortly after vaccines had been made freely available to anyone over the age of 16 in the United States, unvaccinated participants read a manipulated Twitter message designed to be either encouraging or shaming. Message-type did not significantly affect intentions to become vaccinated against COVID-19; however, participants who saw the encouraging message reported that the post made them feel more likely to get vaccinated. Self-efficacy was also manipulated but did not reveal any significant effects. Additional analyses suggest that having personal experience with COVID-19 moderates reactions to these different messages. We discuss limitations and promising avenues for future research on the effects of social media messages on health behaviors. 相似文献

Underpinned by the stimulus–organism–response model, this study explores the underlying mechanism through which green advertising skepticism on social media affects consumer green purchase intention. It also investigates the boundary factors that moderate this indirect relationship. Performing structural equation modeling on data collected from an online survey on Sina Weibo, this study finds that green advertising skepticism on social media negatively affects green purchase intention through the mediation of perceived information utility. Moreover, interdependent self‐construal positively moderates, and independent self‐construal negatively moderates this indirect relationship. These findings suggest that truthful and consumer‐tailored green advertising is crucial to green product marketing. 相似文献

This experiment investigated effects of report order and training on multidimensional stimulus identification. Subjects were required to identify each two-dimensional symbol. There were two orders of reporting the two dimensions of a stimulus. Subjects performed the task for three practice sessions. Both behavioral data and event-related potentials were recorded. Analysis showed order of report had no significant effect on behavior data. But when participants responded in Order Shape/ Part, they showed more N2 inhibition for Order Part/Shape. The P3 mean amplitude was marginally significantly greater for Order Part/Shape than Order Shape/Part. This indicated Order Part/Shape, according to natural language habits, was more appropriate and less cognitively demanding than Order Shape/Part. For the two report orders, along with reduction of reaction time, amplitude of N1 and N2 increased with practice. Amplitude of P2 decreased with practice, and no P3 habituation was found. ERP data indicated no habituation effect. Results suggested neural activity depended not only on perceptual mechanism but also on extent of learning. 相似文献

A number of studies have supported the hypothesis that negative attributional styles may confer vulnerability to the development of depression. The goal of this study was to explore factors that may contribute to the development of negative attributional styles in children. As hypothesized, elevated levels of depressive symptoms and hopelessness at the initial assessment predicted negative changes in children's attributional styles over the 6-month follow-up period. In addition, elevated levels of verbal victimization occurring between the 2 assessments, as well as that occurring in the 6 months preceding the initial assessment, prospectively predicted negative changes in children's attributional styles over the follow-up. Further, initial depressive symptoms and verbal victimization during the follow-up continued to significantly predict attributional style change even when the overlap among the predictors was statistically controlled. Contrary to the hypotheses, however, neither parent-reported levels of overall negative life events nor parents' attributions for their children's events predicted changes in children's attributional styles. 相似文献

新课程背景下上海市中小学教师职业角色认同的研究 总被引:4,自引:0,他引:4
本研究是在了解新课程背景所倡导的教师角色的基础上,对教师职业角色认同状况的调查和分析。结果发现:教师在职业角色认同上可以分两个组:“高认同组”和“一般认同组”。在调查的十个教师职业角色中,“教师是文化的传播者”;“教师是学生学习能力的培养者”;“教师是学生人生的引路人”处于角色认同排序的前三位,“教师是专家”、“教师是教育家”、“教师是社区型的开放的教师”处于排序的后三位,其余“教师是教育教学的研究者”;“教师是学生的心理顾问”;“教师是课程的建设者和开发者”和“教师是学者”居中。教师所处的学校类型、教师性别和是否担任行政职务,在职业角色认同上有非常显著和显著的差异。小学教师的职业角色认同要高于初中教师,初中教师又高于高中教师。女教师的职业角色认同要高于男教师。学校行政领导的职业角色认同要高于普通教师。 相似文献

脑科学研究发现,简单心算主要涉及算术事实的提取,依赖于左半球的语言中枢,而复杂心算激活了左侧顶—额叶网络和双侧颞下回,与视觉空间表征和视觉表象加工有关;精算主要激活左额叶下部区域,而估算激活了两半球更大的区域。在计算过程中所激活的脑区受年龄发展与个体差异以及训练的影响。研究对有效地促进儿童计算能力的发展提供了重要启示。 相似文献
