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.

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.

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.

Pitfalls in Human Research examines 10 ten pivotal points in human research where investigators and experimenters can go astray. Two questions are addressed: At what pivotal points in the complex research process can the experimental study go astray and give rise to misleading results and conclusions? What steps can researchers take to avoid these pitfalls? To answer these questions, those aspects of experimental studies that are under the control of the investigator as well as those aspects that are under the control of the experimenter are examined. This book begins by making a distinction between the investigator and the experimenter, arguing that their roles are functionally quite different. The discussion then turns to the 10 pitfalls in human research, divided into investigator effects and experimenter effects: investigator paradigm effect; investigator experimental design effect; investigator loose procedure effect; investigator data analysis effect; investigator fudging effect; experimenter personal attributes effect; experimenter failure to follow the procedure effect; experimenter misrecording effect; experimenter fudging effect; and experimenter unintentional expectancy effect. This monograph will be a useful resource for both investigators and experimenters, as well as those who utilize research results in their teaching or practice.
