Automation is often problematic because people fail to rely upon it appropriately. Because people respond to technology socially, trust influences reliance on automation. In particular, trust guides reliance when complexity and unanticipated situations make a complete understanding of the automation impractical. This review considers trust from the organizational, sociological, interpersonal, psychological, and neurological perspectives. It considers how the context, automation characteristics, and cognitive processes affect the appropriateness of trust. The context in which the automation is used influences automation performance and provides a goal-oriented perspective to assess automation characteristics along a dimension of attributional abstraction. These characteristics can influence trust through analytic, analogical, and affective processes. The challenges of extrapolating the concept of trust in people to trust in automation are discussed. A conceptual model integrates research regarding trust in automation and describes the dynamics of trust, the role of context, and the influence of display characteristics. Actual or potential applications of this research include improved designs of systems that require people to manage imperfect automation.

This study examines patterns of cellular phone adoption and usage in an urban setting. One hundred and seventy-six cellular telephone users were surveyed about their patterns of usage, demographic and socioeconomic characteristics, perceptions about the technology, and their motivations to use cellular services. The results of this study confirm that users' perceptions are significantly associated with their motivation to use cellular phones. Specifically, perceived ease of use was found to have significant effects on users ' extrinsic and intrinsic motivations; apprehensiveness about cellular technology had a negative effect on intrinsic motivations. Implications of these findings for practice and research are examined.

Even though the literature on the adoption and use of mobile services is quite extensive, surprisingly few studies are found applying traditional models of ICT adoption such as the technology acceptance model. This suggests different perspectives are applied in studies of mobile ICT adoption and traditional ICT adoption. With the introduction of 3G services, a convergence of mobile services and traditional Internet services is expected. Thus, traditional models of ICT adoption may be applied improving our understanding of the adoption of these services. However, studies of the use and adoption of mobile services indicate that traditional adoption models need to be extended and modified when applied to mobile services. In this study, we apply a modified version of the decomposed theory of planned behavior to the adoption behavior of early adopters of mobile commerce services. The study shows that the extended and modified model has good fit to the early adopter data, and that it explains 49 percent of the early adopters' intentions to use mobile commerce services. The model may be used as a basis for industry players' evaluation of the adoption potential of new mobile services.

Tested the hypothesis that perceived controllability and stringency of performance standards would affect self-regulatory mechanisms governing performance attainments of a simulated organization. Ss who managed the simulated organization under a cognitive set that organizations are not easily controllable displayed low perceived self-efficacy, even when standards were within easy reach, and lowered their organizational goals. Ss who operated under a cognitive set that organizations are controllable maintained a strong sense of self-efficacy, set increasingly challenging goals, and exhibited effective analytic thinking. The divergent changes in these self-regulatory factors were accompanied by large differences in organizational attainments. Path analyses revealed that perceived self-efficacy, which was affected by prior accomplishments, influenced subsequent organizational performance through its effects on analytic strategies. After further experience, the performance system was regulated more extensively and intricately by Ss ' self-conceptions of efficacy. Perceived self-efficacy affected subsequent organizational attainments both directly and indirectly through its influence on personal goal challenges. Personal goals, in turn, enhanced organizational attainments directly and through mediation of analytic strategies. Research on cognitive motivators and regulators of action has

Modeling Modeling is not merely a process of behavioral mimicry. Highly functional patterns of behavior, which constitute the proven skills and established customs of a culture, may be adopted in essentially the same form as they are exemplified. There is little leeway for 25 improvisation on how to drive automobiles or to perform arithmetic operations. However, in many activities, subskills must be improvised to suit varying circumstances. Modeling influences can convey rules for generative and innovative behavior as well. This higher-level learning is achieved through abstract modeling. Rule-governed behavior differs in specific content and other details but it contains the same underlying rule. For example, the modeled statements, "The dog is being petted," and "the window was opened" refer to different things but the linguistic rule-- the passive form--is the same. In abstract modeling, observers extract the rule embodied in the specific behavior exhibited by others. Once they lear...

and Creative Modeling Modeling is not simply a process of response mimicry as commonly believed. Modeled judgments and actions may differ in specific content but embody the same rule. For example, a model may deal with moral dilemmas that differ widely in the nature of the activity but apply the same moral standard to them. Modeled activities thus convey rules for generative and innovative behavior. This higher level learning is achieved through abstract modeling. Once observers extract the rules underlying the modeled activities they can generate new behaviors that go beyond what they have seen or heard. Creativeness rarely springs entirely from individual inventiveness. A lot of modeling goes on in creativity. By refining preexisting innovations, synthesizing them into new ways and adding novel elements to them something new is created. When exposed to models of differing styles of thinking and behaving, observers vary in what they adopt from the different sources and thereby create ...
