  • Communication, cognitive processing, and public knowledge about climate change

    • Authors: Shirley S. Ho; Xiaodong Yang (2018)

  • This study advances the cognitive mediation model (CMM) by examining the factors behind acquiring knowledge about climate change. Based on a nationally representative survey of Singaporeans (N = 1,083), this study supported the original CMM. The extended CMM showed that surveillance gratification was positively associated with traditional and online media attention, while social utility was positively associated with online media attention. While attentions to traditional and online media were positively associated with elaboration, online media attention was positively associated with selective scanning. Elaboration was positively associated with knowledge. Implications for theory an...

  • Examining public acquisition of science knowledge from social media in Singapore: an extension of the cognitive mediation model

    • Authors: Shirley S. Ho; Xiaodong Yang; Amber Thanwarani; Juliana M. Chan (2017)

  • This study extends the cognitive mediation model (CMM) by examining the role of social media in cultivating public science knowledge. A sample of 901 Singaporeans was collected through an online survey panel. The results showed that the CMM could be applied to a social media context with a focus on science literacy. Specifically, the findings indicated that people with higher levels of surveillance gratification and social utility motivations tended to pay more attention and to elaborate more about science news that they encounter on social media. Likewise, people with greater social utility motivation tended to engage in greater interpersonal discussions on social media. Notably, att...

  • Explicating factual and subjective science knowledge: knowledge as a mediator of news attention and attitudes

    • Authors: Shirley S. Ho; Jiemin Looi; Alisius D. Leong; Yan Wah Leung (2019)

  • Communication scholars have conflicting views on the relationship between exposure to science news and knowledge, and its subsequent influence on attitudes. Such mixed sentiments could arise from the vague definition of knowledge. Therefore, this paper explicates science knowledge into factual knowledge and subjective knowledge. It also compares the mediating roles of both types of knowledge between news attention and public support for science and technology (S&T). A survey of 967 Singaporeans showed that news attention was positively related to both factual and subjective knowledge. The findings revealed a stronger relationship between subjective knowledge and news attention than factua...

  • Scientists as public communicators: individual-and institutional-level motivations and barriers for public communication in Singapore

    • Authors: Shirley S. Ho; Jiemin Looi; Tong Jee Goh (2020)

  • This study identifies the outreach activities that scientists engage in, as well as their perceived motivations and barriers towards such activities. It examines the forms of communication training that Singapore-based scientists have undergone and the types of communication training they would like to receive. Five focus groups were conducted with scientists across scientific disciplines from public universities and research institutes who engaged in direct and mediated outreach activities. Overall, the lack of time and institutional constraints were the main barriers to outreach activities. Their desire to impact public welfare and secure research funds were primary motivators to cond...

  • Staying abreast of breast cancer: examining how communication and motivation relate to Singaporean women's breast cancer knowledge

    • Authors: Edmund W. J. Lee; Shirley S. Ho (2015)

  • Numerous health communication studies have highlighted the importance of factual knowledge as an antecedent to health behavior, but few have explored other dimensions of health knowledge, such as structural knowledge. This study seeks to fill this gap by investigating conceptual differences between these two kinds of knowledge in the context of breast cancer in Singapore, and find out how communication and motivational factors are related to them. Using a nationally representative random-digit-dialing survey of women aged 30–70 (N = 802), results showed that interpersonal communication and elaboration were associated with both knowledge types. Attention to online health news and the l...
