Focusing on experimental methods, authors Anne Myers and Christine Hansen lead students step by step through the entire research process, from generating testable hypotheses to writing the research report. The major sections of the book parallel the major sections of a research report (Introduction, Method, Results, and Discussion), giving students the skills they'll need to design and conduct an experiment, analyze and interpret the research findings, and report those findings. Although the main focus is on experimentation, alternative approaches are discussed as important complements.
- Chapter 1 now includes information about the history of experimental psychology and expanded explanations of experimentation and control.
- Chapter 14, "Analyzing Results," now discusses the importance of selecting the statistical technique for a study before collecting data--so that the research design is appropriate for the question to be answered.
- Chapter 15, "Drawing Conclusions: The Search for the Elusive Bottom Line," includes new material on the importance and benefits of error and correction, presented at the end of the section on generalizing from procedures to concepts.
- Chapter 16, "Writing the Research Report," has been completely revamped to comply with the new APA publication manual, and includes a new annotated sample article.
- Examples are updated throughout the text in the primary narrative, feature boxes, and lists of Internet resources.
- Expanded discussion of interpretation of nonexperimental designs is accomplished through several new boxes; for example, one on pseudoscience in Chapter 1 and another on ethics in Chapter 4.
- New charts, tables, and figures have been added for visual appeal and to clarify the narrative.
- A new Appendix D includes answers to selected study questions and all critical thinking exercises.
- Chapter 2, "Research Ethics," features expanded coverage of informed consent related to class projects and anonymous questionnaires (including a new Informed Consent Form). There's also expanded information on minors and special populations, more on plagiarism (particularly with respect to material from the Internet), and a new discussion of requirements for the care of lower vs. higher animal species. Finally, the authors added a discussion of a classic Milgram study to explain the concept of beneficence.
- Chapter 3, "Alternatives to Experimentation: Nonexperimental Designs," features a revised discussion of internal validity and new coverage of ethnography.
- Chapter 4, "Alternatives to Experimentation: Surveys and Interviews," includes expanded coverage of interviewing, increased coverage of ethics and Internet surveys, and a new discussion of sampling as a concern for all research (as opposed to being a concern of only surveys).
- Chapter 7, "The Basics of Experimentation," includes an augmented definition of variable.
- Chapter 8, "Solving Problems: Controlling Extraneous Variables," presents expanded coverage on placebo.
- Chapter 10, "Between-Subjects Factorial Designs," integrates material on shorthand notation (formerly in a box) into the primary narrative.
- Chapter 12, "Within-Subjects Designs: Small N," includes expanded coverage on variability and statistics.
- Chapter 13, "Why We Need Statistics," now includes material on prep (an APS journal requirement) in the section on going beyond hypothesis testing.
- The book includes direct links between examples in the text and application via the online Wadsworth Statistics Workshops, accessible at www.cengage.com/psychology/workshops.
- The authors incorporate research examples throughout the text by integrating journal articles in every chapter.
- New American Psychological Association guidelines for reporting statistical results are described and explained.
- Statistical material is included to help students interpret research findings. The results section of the text provides students with a conceptual overview of the process of statistical inference and step-by-step instructions for selecting and carrying out some of the tests commonly used in simple experiments.
- Examples are drawn from a variety of research areas to emphasize the importance of experimental procedures throughout psychological research. The examples, both classic and current, provide clear, concrete illustrations of the concepts under discussion. The eclectic choice of examples gives instructors freedom to supplement the text with content-oriented readings in areas of their choice.
- A detailed chapter on report writing includes a sample journal article to illustrate the most current reporting conventions. (To aid students in producing an APA style report, the manuscript version of this article is reproduced in Appendix C).
- Each chapter ends with an exercise that requires students to think critically about a given research topic.
