DATA ANALYTICS AND PERSUASIVE TECHNOLOGY TO PROMOTE STUDENTS’ ENGAGEMENT AND LEARNING

The use of interactive systems and internet technology nowadays enhance the process of learning as they allow educational resources to be effectively distributed and delivered to students. This gives students the opportunity to learn at their own pace and convenience. Hence, universities employ these computing technologies to aid in teaching and learning in order to meet the needs of diverse learners. Thus, students could engage in learning activities at any time and even outside the four walls of universities. Despite the usefulness of these systems, students find it hard to engage for a long time with these learning resources. They are distracted by so many activities such as chatting, playing games, listening to music, watching movies, etc. As a result, a wide gap exists in academic performance between successful students and unsuccessful one (those that drop out of universities). Therefore, there is a need for research on how to increase students’ motivation to learn. The level of motivation of students to learn and progress in their education determine the length of time they spend on learning-related activities. This research investigated the use of persuasive technology in encouraging students to spend quality time in their learning resources. Persuasive technology describes computer applications which change users’ behaviour or opinion without using coercion or deception. Specifically, this research examined the effect of three social influence strategies of persuasive technology (social comparison, social learning, and competition) on students’ engagement in their learning activities. Socially-oriented strategies recognize the fact that humans are socially-driven and thus, our feeling, behaviour or opinion is affected by that of others (social influence). The strategies were operationalized in a persuasive system as three versions of visualization using students’ assessment grades. The persuasive system was applied to a real university course-based setting to determine its effect on students’ engagement in their learning activities. Quantitative and qualitative approaches were used in determining the effectiveness of the persuasive system versions implementing the three strategies in motivating the students to engage actively in learning activities. The results of this research show that the three socially-oriented strategies of persuasive technology employed can be used in educational software to influence students to achieve a positive goal in their learning. Precisely, the persuasive system attracted and motivated students to spend more time in their learning activities

The impact of online reviews on consumer evaluations and decision making: an analysis of review volume and user-generated photos

This thesis investigates the impact of online social influence on consumer behaviour, specifically within the context of online reviews. It examines how review volume and user-generated photos affect consumer evaluations and decision-making. In Chapter 2, I introduce a novel phenomenon, the N-effect, which explores how opinion volume influences the content of online evaluations. I find that as the number of opinions increases, the content becomes more emotional and less analytical. In Chapter 3, I investigate the role of user-generated photos in shaping purchase intentions. This research demonstrates that photos can enhance review helpfulness, even when they lack diagnostic information. This effect is driven by the confidence signalled by the reviewer when posting a review with a photo, which is later assimilated by readers, leading to increased perceived helpfulness and purchase likelihood. This thesis makes several theoretical and practical contributions to the literature on human interaction with technology. Theoretically, it expands our understanding of online social influence by examining the dynamics of online opinion expression and content. I contribute to the literature on group size by demonstrating how responsibility may be lost in online contexts. Furthermore, the findings provide insights into the social influence of photos on viewers and the role of pseudo-evidence in shaping beliefs and attitudes. From a practical standpoint, this research offers valuable insights for online platform managers and marketers on interpreting and using consumer-written reviews. Overall, this thesis contributes to the existing literature on online social influence and provides insights for businesses to improve communication and interpretation with consumers by better understanding and leveraging online reviews and opinions.Open Acces

Increasing career exploratory behavior through message framing

Career indecision is a growing problem for present day college students. As more and more students attend college right out of high school, rates of\u27 indecision are also rising. The consequences of this include increased time to graduation, increased student loans, and decreased likelihood of career satisfaction and fit. While most institutions of higher learning offer services to help students choose a major and career path, these services remain underutilized. Research in this area has focused on investigating the effectiveness of these interventions, with little attention given to methods of increasing utilization of these services as well as career exploratory behaviors. A method of increasing behavioral compliance which has been extensively researched is message framing, positing that the way a message is worded can affect an individual\u27s receptiveness to that message and likelihood of engaging in the target behavior of the message. This idea has been successfully applied within a wide range of domains, particularly health psychology; however, the application of message framing to increase career exploratory behaviors has not been sufficiently explored. This study sought to explore the effect of a message frame on career exploratory behaviors in a sample of college students in order to provide a better understanding of how message framing can be applied within the career domain, which may assist colleges in better marketing their career services in order to decrease career indecisiveness. A sample of undergraduate students was used and participants were randomly assigned to one of two groups, one received the gain frame message and one received the loss frame message. All participants completed two surveys measuring the variables that were hypothesized to moderate message frame receptivity, locus of control and career decision self-efficacy. Participants answered three questions about how persuasive they found the message and their self-reported intent to engage in career exploratory behaviors after reading the message. It was hypothesized that there would be significant between group differences and that locus of control and career decision self-efficacy would moderate message receptivity and behavioral response to the message. No significant between group differences were found and no significant effects of moderating variables were found; however, recommendations for further research are discussed

Consumer Neuroscience: A Multi-disciplinary Approach to Marketing Leveraging Advances in Neuroscience, Psychology and Economics

For decades, neuroscience has greatly contributed to our foundational understanding of human behavior. More recently, the findings and methods of neuroscience have been applied to study the process of decision-making in order to offer advanced insights into the neural mechanisms that influence economic and consumer choices. In this thesis, I will address how customized marketing strategies can be enriched through the integration of consumer neuroscience, an integrative field anchored in the biological, cognitive and affective mechanisms of consumer behavior. By recognizing and utilizing these multidisciplinary interdependencies, marketers can enhance their advertising and promotional mix to elicit desired neural and affective consumer responses and measure these reactions in order to enhance purchasing decisions. The principal objective of this thesis is to present a comprehensive review of consumer neuroscience and to elucidate why it is an increasingly important area of study within the framework of human behavior. I will also describe how the insights gained from this emerging field can be leveraged to optimize marketing activities. Finally, I propose an experiment that illuminates key research questions, which may have considerable impact on the discipline of consumer neuroscience as well as the marketing industry

Designing Culture-Tailored Persuasive Technology to Promote Physical Activity

Physical inactivity has been recognized as one of the leading risk factors that account for cardiovascular disease, type-2 diabetes, stroke, hypertension, etc., with the World Health Organization labeling it as the fourth leading risk factor for global mortality. Research has shown that persuasive technology (PT) can be leveraged as a motivational/supportive tool in tackling the physical-inactivity problem. In particular, research shows that persuasive health applications (PHAs) are more likely to be effective if they are theorydriven and tailored to the target audience. Yet, most existing PHAs on the market are neither theory-driven nor tailored to the target audience. Rather, their designers often employ a one-size- fits-all approach. This makes it difficult to know what design decisions are effective or ineffective among a given target audience. To bridge this gap, I proposed a framework, called the "EMVE-DeCK Framework," grounded in Bandura's Triad of Reciprocal Determinism, for designing, implementing and evaluating tailored PT interventions. Basically, the EMVE-DeCK Framework employs "Theory" and "Technology" to explain and change "Behavior." Moreover, research shows that culture can be leveraged as a personalization mechanism for tailoring PHAs to the target users to make them more effective. However, there is limited cross-cultural research|grounded in theory and empirical evidence|on the effectiveness of culture-based tailoring, especially comparative studies involving understudied populations in the PT research landscape. Hence, using the Hofstede's cultural framework (individualism vs. collectivism), Social Cognitive Theory, Technology Acceptance Model and the EMVE-DeCK Framework, I conducted a number of comparative studies to understand the culture-speci c determinants of physical-activity behavior and the acceptance of a proposed PHA. I used the ndings to inform the design, implementation and evaluation of two versions of a tness app called BEN'FIT - personal version (PV) and social version (SV) - aimed to motivate bodyweight exercise at home. In this dissertation, using the EMVE-DeCK Framework and Canada/United States (individualist culture) and Nigeria (collectivist culture) as a case study, I describe: (1) the cross-cultural user studies and empirical f indings that informed the PT intervention; (2) the design and implementation of the culture-tailored PHA; (3) the evaluation of the overall and culture-tailoring e ectiveness of the PHA in a eld setting. Finally, based on empirical evidence, I present a set of validated PT design guidelines in the eld for designing and tailoring PHAs to users in the individualist and collectivist cultures. This dissertation makes three major contributions to PT research in the Human-Computer-Interaction domain. Firstly, it demonstrates how theory and culture can be employed in the design and development of PT interventions to motivate behavior change. Secondly, it reveals and validates in the eld how the individualist and collectivist cultures fundamentally differ in their motivational mechanism of behavior change. Thirdly, it provides an in-the- field validates PT design guidelines for developing tailored PHAs for the two main types of culture. In the physical-activity domain, the dissertation is the rst to conduct a theory-driven, in-the-fi eld cross-cultural PT research that focuses on an understudied population from Africa (Nigeria) and compare its ndings with those of a widely studied population from North America (Canada/United States)

Examining Biased Assimilation of Brand-related Online Reviews

This paper examines the impact of pre-existing brand attitudes on consumer processing of electronic word-of-mouth (eWOM). This topic is particularly important for brands that simultaneously possess strongly pronounced proponents as well as opponents. Two experimental studies using univalent (study 1, N = 538) and mixed (study 2, N = 262) sets of online reviews find indications for biased assimilation effects of eWOM processing. Consumers perceive positive (negative) arguments in online reviews as more (less) persuasive when having a positive (negative) attitude towards the brand. Perceived persuasiveness in turn influences behavioral intentions and acts as a mediator on the relationship between attitude and behavioral intentions. We examine two moderators of this effect. When priming individuals to focus on other consumers (vs. a self-focus prime), the biased assimilation effect is weaker (study 3a, N = 131). In contrast, we show that biased assimilation becomes stronger under conditions of high (vs. low) cognitive impairment (study 3b, N = 124). Our findings contribute to the literature on the relationship between eWOM and brands and advance our understanding of potential outcomes of brand polarization

Does the experience of parasocial interaction enhance persuasiveness of video public service messages?

Does the experience of parasocial interaction (EPSI) increase the persuasiveness of a video message? In a between-subjects experiment (N = 465) we used bodily addressing to successfully vary EPSI in viewers of three brief video-recorded health messages. This manipulation, however, yielded no significant effect on viewers’ perceived persuasiveness of the message and their attitude toward the recommended behavior, and the effect on viewers’ felt obligation to comply with the presenter of the message was only marginally significant. However, self-reported EPSI was significantly positively correlated with all persuasion measures, and exploratory analyses yielded significant indirect effects of the manipulation on persuasion via self-reported EPSI. Limitations and implications are discussed
