“…The effect of topic familiarity on attention to semantic content was much more pronounced for undergraduate and postgraduate students than for high school students, however, and high school students had difficulties with considering other types of features when topic familiarity was low (Lucassen et al., ). Similarly, Jung, Walsh‐Childers, and Kim () found that when undergraduates were more knowledgeable and involved in a topic, indicating higher topic familiarity, they took message content but not source expertise into consideration when evaluating documents. However, when participants were less familiar with the topic, source expertise was also taken into consideration.…”

“…We investigated the extent to which source credibility, content relevance, and instructional prompts affected high school students’ selection, processing, and use of documents about a more familiar (i.e., climate change) or a less familiar socioscientific topic (i.e., nuclear power). Topic familiarity referred to learners’ topic knowledge and topic interest for the specific topics (Jung et al., ; Lucassen et al., ; McCrudden et al., ). Participants were randomly assigned to work with 20 documents that pertained to either the more familiar or the less familiar topic.…”

This study investigated the effects of author expertise and content relevance on Norwegian secondary school students’ (n = 190) selection, processing, and use of multiple documents. Participants were presented with documents that pertained to more or less familiar topics, and received brief instructions that highlighted the importance of source credibility or content relevance, whereas those in a control group just received a general task instruction (to write a letter to the editor about their assigned topic). Results showed that content relevance had strong and nearly identical effects on students’ selection, processing, and use of documents independently of whether the topic was more or less familiar, whereas they valued author expertise to a greater extent when the topic was less familiar. Moreover, content relevance had a strong effect on students’ selection, processing, and use of documents independently of instructional condition, whereas brief instructions to focus on source credibility increased the value placed on author expertise when students selected, processed, and used documents for the less familiar topic. Theoretical and practical implications of the results are discussed.

“…In order to effectively use internet‐based devices to find information, children must determine whether to trust the information that these devices provide. By adolescence, internet users are aware that not all the information they find online is credible or accurate (e.g., Jung, Walsh‐Childers, & Kim, ; St. Jean, Greene Taylor, Kodama, & Subramaniam, ), yet they are still vulnerable to believing false information found online (Metzger, Flanagin, Markov, Grossman, & Bulger, ). Moreover, adults show a good deal of trust in internet search engines and confidence in their own ability to use search engines to find the most relevant information (Pan et al, ; Purcell, Rainie, & Brenner, 2012).…”

Children are increasingly exposed to devices that can access the internet, such as computers, smartphones, and tablets, beginning early in life. This review summarizes current evidence regarding the understanding and use of internet‐based devices among children from birth through age 8, while highlighting gaps in the literature and opportunities for future research. The first section describes children's access to internet‐based devices, and discusses the role that parents play in mediating children's access to internet‐based devices. The second section describes children's developing understanding of how internet‐based devices work and what they can do, and how capable children are of accessing information from the internet using these devices. The third section discusses potential implications of children's use of internet‐based devices for children's cognitive development, with an emphasis on the development of memory, metacognition, and exploration.

“…Computers do not have a direct impact on physical health activities but play an intellectual role in online social awareness. The reliability of messages and information along with the trustworthiness of websites are important with regards to health [24]. However, users' views about their health conditions were the same after using an app as before using the app [25].…”

Although social presence plays an essential role under general conditions, its role becomes significant for societal protection during the quarantine period in epidemic outbreak. In this study, we attempted to identify the role of E-government and COVID-19 word of mouth in terms of their direct impact on online social presence during the outbreak as well as their impacts mediated by epidemic protection and attitudes toward epidemic outbreaks. For this purpose, a unique multi-mediation model is proposed to provide a new direction for research in the field of epidemic outbreaks and their control. Through random sampling, an online survey was conducted and data from 683participants were analyzed. Partial least squares structural equation modeling was used to test the relationships between the variables of interest. The study results revealed that the roles of E-government and COVID-19 word of mouth are positively related to online social presence during the outbreak. Epidemic protection and attitude toward epidemic outbreak were found to positively moderate the impact of the role of E-government and COVID-19 word of mouth on online social presence during the outbreak. The key findings of this study have both practical and academic implications. health protection. This phenomenon encouraged us to formulate a theoretical model based on social presence theory and the role of social media to help examine safety and participation in quarantine. The conceptual model is presented in Figure 1.Word of mouth can be defined as "the intention to share a certain story using one's own social media account" [2]. Many researchers proved that communication has more of an impact through social media with regards to different health issues, and message sharing was found to be the best predictor of emotive and passionate response [3]. Online health information is regularly updated [4]. Nowadays, universal and worldwide flow cannot be ignored [5] and search engines are the most effective method to find information [6]. The Internet is also a useful source for people in the medical field for discussions and interactions about medical issues [7]. A nine-year big data study showed that the use of computers projected emotive improvement [8]. From the health protection point of view, many factors were found to affect the dispersal of cancer information, including anxiety, courage, anticipation, and sharing of experience [9].A study proved that the gestation time of infection (corona virus) was assessed at about 2-14 days [7]. So, a research question was raised about protection during an epidemic outbreak. Social media campaigns with complete research frameworks with theoretical and statistical support for these time periods are essentially to protect society during emergencies. To address this need, our research model includes the factors that trigger safety campaigns and the main effects (direct) of direct relations and the association of mediators on online social presence.The literature shows that for different disease management programm...
