In this paper, we propose design strategies for persuasive technologies that help people who want to change their everyday behaviors. Our strategies use theory and prior work to substantially extend a set of existing design goals. Our extensions specifically account for social characteristics and other tactics that should be supported by persuasive technologies that target long-term discretionary use throughout everyday life. We used these strategies to design and build a system that encourages people to lead a physically active lifestyle. Results from two field studies of the system—a three-week trial and a three-month experiment—have shown that the system was successful at helping people maintain a more physically active lifestyle and validate the usefulness of the strategies.

This paper presents a model of the behavior of candidates for promotion to administrator status in Wikipedia. It uses a policy capture framework to highlight similarities and differences in the community’s stated criteria for promotion decisions to those criteria actually correlated with promotion success. As promotions are determined by the consensus of dozens of voters with conflicting opinions and unwritten expectations, the results highlight the degree to which consensus is truly reached. The model is fast and easily computable on the fly, and thus could be applied as a self-evaluation tool for editors considering becoming administrators, as a dashboard for voters to view a nominee’s relevant statistics, or as a tool to automatically search for likely future administrators. Implications for distributed consensus-building in online communities are discussed. Author Keywords Wikipedia, administrators, management, collaboration,

The consumption of energy is unlike most consumable goods. It is abstract, invisible, and untouchable. Without a tangible manifestation, home energy usage often goes unnoticed. Advances in resource monitoring systems will soon provide real-time data on electricity, gas, and water usage in the home. This will produce a tremendous amount of data that can be analyzed and fed back to the user—creating a rich space of opportunities for HCI research. This paper outlines common misconceptions of energy usage in the home, establishes the potential of feedback to change energy consumption behavior, and introduces ten design dimensions of feedback technology with which to build and evaluate future systems.

The present study discusses findings that replicate and extend the original work of Burns and Vollmeyer (2002), which showed that performance in problem solving tasks was more accurate when people were engaged in a non-specific goal than in a specific goal. The main innovation here was to examine the goal specificity effect under both observation-based and conventional action-based learning conditions. The findings show that goal specificity affects the accuracy of problem solving in the same way, both when the learning stage of the task is observationbased and when it is action-based. Additionally, the findings show that, when instructions do not promote goal specificity, observation-based problem solving is as effective as action-based problem solving. 2 Keywords: Problem solving; Skill acquisition and learning; Observation vs. intervention

Progress towards understanding human behavior has been hindered by discipline-bound theories, dividing our efforts. Fortunately, these separate endeavors are converging and can be effectively integrated. Focusing on the fundamental features of Picoeconomics, Expectancy, Cumulative Prospect Theory, and Need Theory, Temporal Motivational Theory (TMT) is constructed. TMT appears consistent with the major findings from many other investigations, including psychobiology. Potential applications of TMT are numerous, including: consumer behavior, aggression, stock market, and governmental behavior.

At personal goal-setting websites, people join others in committing to a challenging goal, such as losing ten pounds or writing a novel in a month. Despite the popularity of these online communities, we know little about whether or how they improve goal performance. Based on theories of goal-setting and group attachment, we examine the influence of two social factors in an online “songwriting challenge ” community: early feedback evoking a shared social identity, and one-on-one collaborations with other members. Combining five years of longitudinal behavioral data with member surveys, we find that users who engage in these social features perform better on their goals than those who are non-social. Furthermore, these early social experiences are associated with strong community-centric behaviors in the long term, including donating money and providing feedback to others.

I understand that my thesis may be made electronically available to the public. ii This paper examines the effect of impression management on goal level and commitment to the goal. Participants involved in a goal-setting program in the United States were asked to complete a web survey regarding their desire to impress superiors and their commitment to the goal. The specific dependant measures were self-set goal and goal commitment. No statistically significant differences were found between high and low desires to manage impressions with respect to goal set, but a higher desire to manage impressions was positively correlated with a higher degree of goal commitment. This finding suggests that triggering impression management is beneficial for situations in which high goal performance is desired as it increases goal commitment. Future studies could verify these results using larger sample sizes and tackle such issues as goal

When hard to use computers cause users to become frustrated, it can affect workplace productivity, user mood, and interactions with other co-workers. Previous research has examined the frustration that graduate students and their families face in using computers. To learn more about the causes and effects of user frustration with computers in the workplace, we collected modified time diaries from 50 workplace users, who spent an average of 5.1 hours on the computer. In this experiment, users reported wasting on average, 42-43 % of their time on the computer due to frustrating experiences. The causes of the frustrating experiences, the time lost due to the frustrating experiences, and the effects of the frustrating experiences on the mood of the users are discussed in this paper. Implications for designers, managers, users, information technology staff, and policymakers are discussed.

The role of action has been strongly emphasized, not only in cognitive research on learning and problem solving, but also in education and instructional psychology. The Constructivism tradition has long asserted that action plays a crucial role for learners in constructing their own knowledge. In an educational context, active engagement entails students examining their own ideas, considering alternative explanations for newly taught concepts, and evaluating competing perspectives. Some theorists (e.g., Anzai & Simon, 1979) propose that these processes are found when learning is by doing. However, a constructivist perspective implies that instructional formats enable self-monitoring (e.g., Covington, 2000; Pintrich & De Groot, 1990), which includes reflective activities such as describing, explaining, and evaluative thinking (e.g., Covington, 2000; Zimmerman, 1990), which are not exclusive to action. The present article discusses findings that concern two related and thus far, unexplored two questions: How affective is observation-based learning in a complex skill learning task that usually requires processes that involve active engagement with it? How does monitoring affect the transfer of problem solving ability in complex skill learning task? The first aim of the article is to introduce ways of using common educational tools like the self-observation technique, which involves re-exposing individuals to their own self-generated behaviors, in novel ways that can provides insight into how people use self-regulatory mechanisms like monitoring on internally represented behaviors. The second aim is provide support for the view that in the absence of active learning, learning indirectly (i.e. Observation-based learning) is a practical and in some cases necessary method of knowledge and skill acquisition, and does not in turn lead to decrements in acquired knowledge and skill. Finally, the article presents the argument that the degree of self-monitoring that takes place may be a mediating factor in preserving the view that action has a special status in knowledge acquisition.

Although white collar work is of vast importance to the economy, the Operations Management (OM) literature has focused largely on traditional blue collar work. In an effort to stimulate more OM research into the design, control and management of white collar work systems, this paper provides a systematic review of disparate streams of research relevant to understanding white collar work from an operations perspective. Our review classifies research according to its relevance to white collar work at individual, team and organizational levels. By examining the literature in the context of this framework, we identify gaps in our understanding of white collar work which suggest promising research directions.
