This volume was designed as both introduction and reminder - an introduction to the topic for graduate students, advanced undergraduates and younger researchers, and a reminder to more experienced researchers, in and out of academia, that the problems of artifacts in behavioural research have not gone away.

This new combination volume of three-books-in-one, dealing with the topic of artifacts in behavioral research, was designed as both introduction and reminder. It was designed as an introduction to the topic for graduate students, advanced undergraduates, and younger researchers. It was designed as a reminder to more experienced researchers, in and out of academia, that the problems of artifacts in behavioral research, that they may have learned about as beginning researchers, have not gone away. For example, problems of experimenter effects have not been solved. Experimenters still differ in the ways in which they see, interpret, and manipulate their data. Experimenters still obtain different responses from research participants (human or infrahuman) as a function of experimenters' states and traits of biosocial, psychosocial, and situational origins. Experimenters' expectations still serve too often as self-fulfilling prophecies, a problem that biomedical researchers have acknowledged and guarded against better than have behavioral researchers; e.g., many biomedical studies would be considered of unpublishable quality had their experimenters not been blind to experimental condition. Problems of participant or subject effects have also not been solved. We usually still draw our research samples from a population of volunteers that differ along many dimensions from those not finding their way into our research. Research participants are still often suspicious of experimenters' intent, try to figure out what experimenters are after, and are concerned about what the experimenter thinks of them.

This work shows how unintended or uncontrolled factors (artifacts) can confound the outcome of behavioural research, demonstrates how things can go wrong when people are involved and addresses ways to overcome the difficulties of applying the scientific method to behavioural studies. For Psychology students in further and higher education.

Providing both a theoretical understanding of research issues and a nuts-and-bolts guide, this book presents the critical issues in psychological research in a clear and easy-to-read manner. Presented within the critical context of validity and reliability the author addresses all the steps of the research process: from formulating a hypothesis, to specifying variables, to creating a research design, to collecting and analyzing data, to drawing conclusions, to reporting the results. A companion website (www.sagepub.com//cherulnik) for professors and students contains additional supporting materials.

Design-type research deals with the multidisciplinary issues of methodology of design, design principles and guidelines, and philosophy of design with the aim of producing knowledge that aids designers in becoming more effective and efficient. Design-Type Research in Information Systems: Findings and Practices aims to demonstrate that Design-Type Research is a legitimate scientific activity, particularly in the context of the field of Information Systems. Contending that the philosophy, methodology and principles of traditional science also apply to design-type of science, the research contained within this book is important to the widespread acceptance and promotion of design-type research.

An interdisciplinary overview of current research on imitation in animals and artifacts.
