David W. Martin's unique blend of informality, humor, clear instruction, and solid scholarship make this concise text a popular choice for research methods courses in psychology. DOING PSYCHOLOGY EXPERIMENTS guides students through the experimentation process in a step-by-step manner, teaching them how to design, execute, interpret, and report on simple psychology experiments. Martin emphasizes the decision-making aspects of research, as well as the logic behind research procedures. He also devotes two separate chapters to many of the ethical questions that confront new experimenters - making this text a complete introduction to the psychology laboratory.
- Thoroughly updated research references have been added throughout.
- Chapter 3 now contains a short discussion of the difference between theories that answer proximate question versus ultimate questions.
- Chapter 4 has an expanded discussion of using the term "participants" rather than "subjects" to include some dissenting points of view. The section on animal ethics has been updated.
- In Chapter 5 the author expanded the discussion of plagiarism, discussed plagiarizing from the internet, and added some specific examples of violations, and now includes the latest version of the APA Ethical Principles of Psychologists and Code of Conduct as it relates to research.
- The section in Chapter 6, on doing electronic searches including additional information on PsycINFO and PsycARTICLES, has been updated.
- The discussion of the logic of inferential statistics in Chapter 12, now includes more information about null hypothesis testing, Type I and Type II errors, and determining the power of statistical tests, in addition there is also a brief discussion of three-way interactions.
- The section in Chapter 13, on giving conference presentations, has been updated because nearly all presentations are now computer-based.
- In response to reviewer suggestions, the author now includes the proper way to format statistical outcomes within the text of a manuscript, so these are included after each of the worked examples in Appendix A.
- Includes extensive coverage of survey techniques, including surveys by means of interviews, phone, mail, and the Internet.
- Discusses the benefits derived from animal research, as well as the strict standards required of labs doing this research.
- Early coverage of external and internal validity and various threats to internal validity help clarify students' understanding of confounding variables.
- Discussion of between-subject designs precedes coverage of within-subject designs.
- Martin shows students how to perform electronic searches - and he outlines the advantages and pitfalls of using the Internet as an information source.
