Human vs. Artificial Intelligence
This study conceptualizes the interaction between consumers and artificial intelligence (AI) influencers as a dynamic persuasion game between human intelligence and artificial intelligence. Specifically, we investigate how consumers’ agent knowledge of algorithmic awareness (representing human intelligence) and the interactivity of AI influencers (representing artificial intelligence) jointly shape consumer responses grounded in the theoretical f…
Dark Patterns in Data-Consent Disclosures and Consumer Reactance to Online Behavioral Advertising
This research investigates how dark patterns in data consent disclosures influence consumer responses to online behavioral advertising (OBA). Integrating the persuasion knowledge model (PKM), psychological reactance theory (PRT), and a cognitive accessibility perspective, we propose a framework explaining how manipulative consent designs shape perceptions of privacy threat, control, and persuasion outcomes. Across three studies, we demonstrate th…
AI versus Human
Despite the exponential growth of influencer marketing, little research has examined how consumers’ coping mechanism differs with two types of influencers (AI vs. human). Drawing on the persuasion knowledge model, action identification theory, and construal-level theory, we redefined agent knowledge as a core belief that shapes different autonomy perceptions of the influencers. Employing two single-factor between-subject experiments, Study 1 reve…
Avoidance and Acceptance of Native Advertising on Social Media
Despite its growing popularity and importance, little research has been done to understand what mechanism drives consumers to avoid or accept native advertising on social media. This study applied the ideas of consumer social intelligence, persuasion knowledge (PK), and the typology of consumer response strategy to examine how consumers’ naive theory of persuasion is associated with their evaluation of the persuasion, which in turn relates with s…
Effects of Affect
An experiment was conducted with the goal of determining how mood and arousal influence the way consumers process ad information in a search engine result page (SERP) environment. By focusing on the relationships among mood, arousal, and search ad snippet length, the study shows that mood and arousal states influence information processing (heuristic vs. systematic) on search pages both independently and jointly. Using the heuristic-systematic mo…
How Political Interest and Gender Influence Persuasion Knowledge, Political Information Seeking, and Support for Regulation of Political Advertising in Social Media
Political advertising in the United States is regulated differently from commercial advertising, and regulations vary by media. The relative lack of regulations on social media has led to the dissemination of false information, often without source disclosure, which is harmful to democracy. In response, in a self-regulatory capacity, Twitter stopped accepting political advertising in 2019, launching a debate over political advertising regulation.…
Exploring how consumers cope with online behavioral advertising
This study explores how consumers cope with a computer technology-driven persuasion tactic called online behavioral advertising (OBA). By tracking consumers’ online behaviors, OBA delivers highly tailored advertising messages to individual consumers, giving rise to serious privacy concerns due to their covert nature. Integrating the persuasion knowledge model and the protection motivation theory, we employed a survey method (N = 442) to examine h…
A Double-Edged Sword? Predicting Consumers' Attitudes Toward and Sharing Intention of Native Advertising on Social Media
Despite the increasing popularity and advantage of native advertising on social media, advertisers are concerned about the possibility of native ads misleading consumers, resulting in boomerang effects. This study attempts to address this concern by comparing the predictive role of native ad nonintrusiveness with that of native ad manipulativeness in consumers' attitude toward and sharing intention of native advertising. Findings from an online s…
