During the past two decades there has been a growing level of concern worldwide regarding the importance of ethical issues within the conduct of behavioral sciences research. This book seeks to reflect that concern, attempting throughout to strike a balance between the rights and welfare of the participants of research and the rights of the researchers to pursue a fuller understanding of behavior. Discussion within the text ranges from problems encountered in the conduct of human subject and animal subject research in both laboratory and field settings to the issues surrounding integrity in the analysis of data and professional ethical principles. Each chapter includes illustrative case studies of ethically controversial investigations which, combined with a full bibliography, encourage the reader to more in-depth study.
