The human–computer interaction (HCI) for mobile applications is becoming increasingly important as mobile applications have become an integral part of everyday life. Mobile app developers need to continuously improve the users’ experience to fulfill their conditions, which in turn, can trigger the purchase decision. Trust is another important factor, driving users to adopt mobile apps and use them to make online purchases. However, mobile app developers constantly face the dilemma between user trust and HCI experiences. This study’s primary purpose is to investigate the HCI and trust factors for the continued use of mobile payment apps and their services. Based on the human–computer interaction, task–technology fit, and IS success theories, an integrative framework is proposed to examine the relationships between continuance intention and its antecedents. An online survey was conducted to collect data from 544 mobile users. The results of the analyses indicate that trust plays a more significant role than HCI in increasing the users’ continuance usage of mobile payment services. As for improving HCI experiences for users, this study shows that system quality plays the most important role, followed by the skill of using mobile payment services and the perceived task–technology fit (TTF) for using the services. Information quality does not significantly impact the enhancement of positive HCI experiences. The results provide insights for the developers of mobile payment services to improve the user experience.

Communication scholars have conducted a significant amount of research to explore the conditions under which exposure to narrative messages affects individuals’ attitudes and behaviors. Perceived character typicality, defined as the degree to which characteristics of a character are perceived to be present among the portrayal’s real-world counterparts, as well as cued typicality, defined as statements about a population that indicate whether the character or the narrative is typical or not, have not been examined in understanding the effectiveness of health messages. The present research explored the effects of perceived character typicality and contextually-embedded typicality cues on persuasive outcomes. It also investigated the underlying mechanisms mediating the impact of narratives with character or cued typicality. A 2 (character typicality: typical vs. nontypical character) × 3 (typicality cues: typical cues vs. nontypical cues vs. no cues) between-subjects experiment was conducted, focusing on the risks of sun exposure without applying sunscreen. The findings showed that a narrative with a character perceived as typical led to higher perceived realism, more positive attitude toward sunscreen use, and less message novelty than a narrative with a character perceived as nontypical. Typical cues had more positive impact on issue attitude than nontypical cues.

Corporate social responsibility (CSR) plays a critical role in the relationships between an organization and its stakeholders. Previous studies showed that CSR initiatives positively affected a company’s image, consumer satisfaction, and product evaluation. Effective communication of an organization’s CSR commitment with stakeholders is not only an ethical practice, but also a strategic concern. The present study aims to explore the effects of message format (narrative vs. nonnarrative) and disclosure type (present vs. absence) when communicating a brand’s CSR initiatives on message effectiveness and sponsorship transparency. The findings showed that a narrative message led higher level of transportation than a nonnarrative message. When the message did not contain endorsement information, participants who read the nonnarrative message rated the message higher in sponsorship transparency than those who read the narrative message.
