As we begin a new century, the astonishing spread of nationally and internationally accessible computer-based communication networks has touched the imagination of people everywhere. Suddenly, the Internet is in everyday parlance, featured in talk shows, in special business "technology" sections of major newspapers, and on the covers of national magazines. If the Internet is a new world of social behavior it is also a new world for those who study social behavior. This volume is a compendium of essays and research reports representing how researchers are thinking about the social processes of electronic communication and its effects in society. Taken together, the chapters comprise a first gathering of social psychological research on electronic communication and the Internet.
The authors of these chapters work in different disciplines and have different goals, research methods, and styles. For some, the emergence and use of new technologies represent a new perspective on social and behavioral processes of longstanding interest in their disciplines. Others want to draw on social science theories to understand technology. A third group holds to a more activist program, seeking guidance through research to improve social interventions using technology in domains such as education, mental health, and work productivity. Each of these goals has influenced the research questions, methods, and inferences of the authors and the "look and feel" of the chapters in this book.
Intended primarily for researchers who seek exposure to diverse approaches to studying the human side of electronic communication and the Internet, this volume has three purposes:
* to illustrate how scientists are thinking about the social processes and effects of electronic communication;
* to encourage research-based contributions to current debates on electronic communication design, applications, and policies; and
* to suggest, by example, how studies of electronic communication can contribute to social science itself.

How insights from the social sciences, including social psychology and economics, can improve the design of online communities. Online communities are among the most popular destinations on the Internet, but not all online communities are equally successful. For every flourishing Facebook, there is a moribund Friendster-not to mention the scores of smaller social networking sites that never attracted enough members to be viable. This book offers lessons from theory and empirical research in the social sciences that can help improve the design of online communities. The authors draw on the literature in psychology, economics, and other social sciences, as well as their own research, translating general findings into useful design claims. They explain, for example, how to encourage information contributions based on the theory of public goods, and how to build members' commitment based on theories of interpersonal bond formation. For each design claim, they offer supporting evidence from theory, experiments, or observational studies.

This special issue is made up of five articles which cover the emerging area of human-robot interaction. The first paper offers a theoretical ecological framework for the design of personal service robots in homes of elderly people. Next, a field study of two robots that visited a children's elementary school in Japan for two weeks, with the purpose of teaching children English, is presented. The third article reports on an opportunistic field study of search and rescue robots used as part of a night rescue training exercise. A different perspective on human-computer interaction for search and rescue robots is discussed in the fourth paper. Finally, an experimental laboratory study is presented that explores how people who have to work closely with professional service robots will perceive and work with them. Taken as a whole, these articles represent some of the first systematic empirical research in human-robot interaction.
