Information accessibility as a moderator of judgments : The role of content versus retrieval ease

We hypothesize that the accessibility of task-relevant knowledge determines whether judgments reflect the substance of the information that is brought to mind or the ease of generating and retrieving such information. Our findings indicate that when relevant knowledge is highly accessible or not at all accessible, judgments are based on the content of the information considered. Between these extremes in knowledge accessibility, judgments are based on the perceived ease with which information can be retrieved. This perceived ease is a function of both the number of reasons requested and the wording of the retrieval request. (c) 2005 by JOURNAL OF CONSUMER RESEARCH, Inc..

Tariff choice of online contents based on usage goal and self-control: can I control myself?

Purpose – People can easily track and understand their usage pattern for any content (e.g. movies, games) or service (e.g. card payment, cell phone usage) by using technologies such as the internet and smart phones. When consumers evaluate their past consumption patterns, they may experience two different kinds of regret: content-based or monetary-based. The purpose of this paper is to propose that perceived self-control, defined as the extent to which people believe they can control their usage, plays a moderating role in the tariff-choice process (flatrate vs pay-per-use) for two types of content: vice-based and virtue-based. Design/methodology/approach – Two laboratory experiments were designed to test the hypotheses. There were a total of 200 participants (86 for Experiment 1 and 114 for Experiment 2) who completed the entire experimental process (i.e. stimulus exposure, questionnaire reporting, dependent variable measurement, manipulation of the independent variables, and control checks). Findings – ...

Analysis on the Diffusion and the Intention to Use among Technology Adopter Categories

Submitted:July 2, 2014 1 Revision:August 23, 2014 Accepted:August 27, 2014 * 대전대학교 경영대학 무역통상학과 교수 ** 연세대학교 경영대학 교수, 교신저자 *** 연세대학교 경영대학 교수 **** 연세대학교 기술경영협동과정 박사과정 ***** TNS Korea 연구원 The purpose of this study is to examine factors affecting the diffusion and the intention to use, and how these factors differ among adopter categories. A survey was done to analyze the diffusion of smart-phone, the most popular and innovative product nowdays. We collected 197 survey questionnaires from smart-phone user and analyzed the data using SPSS 18.0 and Smart PLS 2.0. PLS (Partial Least Square) analysis was implemented before multiple group-innovator, early adopter, eraly majorityanalysis which is categoriezed by Innovation Diffusion Model of Rogers (1995). The results show that firstly, in innovator group (n=63), the functional and the safety value have significantly positive effect on user satisfaction. In addition, we found that user satisfaction and the brand loyalty are significatly associated with the intention of use. Secondly, in early adopter group (n = 67), the design value has significantly positive effect on user satisfaction and it has significantly positive effect on brand loyalty. Finally, in early majority group (n = 67), the design value has significantly positive effect on the user satisfaction and it has stronger effect on the intention of use and brand loyalty. We conclude this paper with the implication of this study to both academia, business practice, and policy making.
