Designing Experiments and Analyzing Data: A Model Comparison Perspective (3rd edition) offers an integrative conceptual framework for understanding experimental design and data analysis. Maxwell, Delaney, and Kelley first apply fundamental principles to simple experimental designs followed by an application of the same principles to more complicated designs. Their integrative conceptual framework better prepares readers to understand the logic behind a general strategy of data analysis that is appropriate for a wide variety of designs, which allows for the introduction of more complex topics that are generally omitted from other books. Numerous pedagogical features further facilitate understanding: examples of published research demonstrate the applicability of each chapter's content; flowcharts assist in choosing the most appropriate procedure; end-of-chapter lists of important formulas highlight key ideas and assist readers in locating the initial presentation of equations; useful programming code and tips are provided throughout the book and in associated resources available online, and extensive sets of exercises help develop a deeper understanding of the subject. Detailed solutions for some of the exercises and realistic data sets are included on the website (DesigningExperiments.com). The pedagogical approach used throughout the book enables readers to gain an overview of experimental design, from conceptualization of the research question to analysis of the data. The book and its companion website with web apps, tutorials, and detailed code are ideal for students and researchers seeking the optimal way to design their studies and analyze the resulting data.

This book concerns the wanting, getting, and giving of power. Recent advances in medicine, sociology, and psychology have deepened our understanding of the motives, skills, and experience that operate between leaders and those who are led. Since power is about decision-making, it figures not only in offi cial institutions but in other organizations, including political parties, pressure groups, trade associations, business enterprises, trade unions, and many other types of organizations.A general theory of the political personality is set forth here. Lasswell describes the process by which power becomes a value of first importance and the way appropriate skills in exercising power are acquired. He shows that special political types such as agitators or administrators are related to basic types of character that contribute to how they lead. Finally, his analysis offers original perspectives to understand democratic leadership.Lasswell offers definite suggestions for perfecting self-observatories in national and world affairs and for forming democratic personalities, selecting and training democratic leaders, and reducing destructive conflicts in human relationships. Power and Personality followed the author's 1930 work Psychopathology and Politics, which was widely hailed for its pioneering approach. Power and Personality reevaluated the entire issue of the relationship between psychology and politics in the light of subsequent experience and scientific developments since publication of that earlier work. Lasswell's ideas continue to carry great weight and persuasiveness.

Through this book's unique model comparison approach, students and researchers are introduced to a set of fundamental principles for analyzing data. After seeing how these principles can be applied in simple designs, students are shown how these same principles also apply in more complicated designs. Drs. Maxwell and Delaney believe that the model comparison approach better prepares students to understand the logic behind a general strategy of data analysis appropriate for various designs; and builds a stronger foundation, which allows for the introduction of more complex topics omitted from other books. Several learning tools further strengthen the reader's understanding: •flowcharts assist in choosing the most appropriate technique; •an equation cross-referencing system aids in locating the initial, detailed definition and numerous summary equation tables assist readers in understanding differences between different methods for analyzing their data; •examples based on actual research in a variety of behavioral sciences help students see the applications of the material; •numerous exercises help develop a deeper understanding of the subject. Detailed solutions are provided for some of the exercises and •realistic data sets allow the reader to see an analysis of data from each design in its entirety. Updated throughout, the second edition features: •significantly increased attention to measures of effects, including confidence intervals, strength of association, and effect size estimation for complex and simple designs; •an increased use of statistical packages and the graphical presentation of data; •new chapters (15 & 16) on multilevel models; •the current controversies regarding statistical reasoning, such as the latest debates on hypothesis testing (ch. 2); •a new preview of the experimental designs covered in the book (ch. 2); •a CD with SPSS and SAS data sets for many of the text exercises, as well as tutorials reviewing basic statistics and regression; and •a Web site containing examples of SPSS and SAS syntax for analyzing many of the text exercises. Appropriate for advanced courses on experimental design or analysis, applied statistics, or analysis of variance taught in departments of psychology, education, statistics, business, and other social sciences, the book is also ideal for practicing researchers in these disciplines. A prerequisite of undergraduate statistics is assumed. An Instructor's Solutions Manual is available to those who adopt the book for classroom use.

This award-winning book provides an analysis of the genetic/evolutionary, cultural/historical, and developmental aspects of prejudice and discrimination. It emphasizes how certain genetic/evolutionary mechanisms are utilized to both produce and prevent prejudice and discrimination from occurring or to modify these behaviors once established. The goals of the book are to help us understand the limitations of interventions and increase tolerance and acceptance of outsiders. Peer Prejudice and Discrimination, Second Edition is ideal for advanced-level courses on prejudice and/or discrimination taught in departments of psychology, education, and sociology, as well as a valuable addition to any serious scholars personal library.

Originally published in 1984, this book is a developmental psychology text with substantial evolutionary and cross-cultural work. It presents cognitive developmental issues, as well as personality, social and socialization issues, with an emphasis on culture. It also includes education-related research, such as material on schools, reading, mathematics, and IQ.

A report of research on two groups of residentially placed, emotionally disturbed adolescents compared on the basis of their adoptive status. A post hoc comparison with a nondisturbed adoptive group is also included.... McRoy, Grotevant, and Zurcher examine factors related to adoption that may contribute to the development of emotional difficulties. The authors'suggestions are worthy of consideration by professionals in the field.... The theoretical reviews of potential sources of difficulty in adoption are well done and informative, and the presentation of the perspectives of both adoptees and adoptive parents is also laudable. ChoiceMany adopted children experience emotional disorders during adolescence that require residential treatment. This volume reports research findings comparing adopted and non-adopted adolescents in treatment. The authors first discuss the difficulties of the adolescent period itself, particularly as it relates to identity problems. Based on extensive interviews with adoptive and non-adoptive parents, adolescents, and their therapists, successive chapters analyze genetic risk and prenatal care, explore the impact of family and peer relationships, examine familiar and contextual factors that initiate and maintain emotional problems, and examine adoptive family dynamics and adoption issues in nonclinical families. The various theoretical perspectives research findings, and well-reasoned recommendations in this volume will interest social workers, clinical and developmental psychologists, and special education professionals.
