Psychology: Themes and Variations
Format: PDF / Kindle (mobi) / ePub
PSYCHOLOGY: THEMES AND VARIATIONS, 10th Edition, is a fusion of the full-length and briefer versions that preceded it. The text continues to offer a superb thematic organization together with practical applications and examples that help students see beyond research to big-picture concepts. Often described as a challenging book that is easy to learn from, the book surveys psychology's broad range of content with three aims: to illuminate the process of research and its relationship to application, to show both the unity and diversity of psychology's subject matter, and to help students master the basic concepts and principles of psychology with as little struggle as possible. Weiten's themes provide unifying threads across chapters that help students to see the connections among different research areas in psychology. A dynamic, teaching-oriented illustration program -- including new color-coded Concept Charts -- further enhances these themes.

placebo effects can be assessed by including a fake version of the experimental treatment (a placebo condition) in a study. Distortions in Self-Report Data Research psychologists often work with self-report data, consisting of subjects’ verbal accounts of their behavior. This is the case whenever questionnaires, interviews, or personality inventories are used to measure variables. Self-report methods can be quite useful. They take advantage of the fact that people have a unique opportunity to
