This open access textbook was developed as an upper division undergraduate textbook for theories of personality. Its intended audience are students from Portland State University enrolled in Psychology 432 Personality course. The chapters are shorter than some personality textbooks and in this particular course Psy 432 the textbook is combined with other readings including scientific articles on personality.

This open resources textbook contains 10 Units that describe and explain the main concepts in statistical analysis of psychological data (managing data, measures of central tendency, measures of spread, correlations, simple linear regression). In addition to conceptual descriptions and explanations of the basic analyses for descriptive statistics, this textbook also explains how to conduct those analyses with common statistical software (Excel) and open-source free software (R). This book is directed to undergraduates studying basic statistics, especially basic statistics in psychological research.

We think important objects and events in our world will automatically grab our attention, but they often don’t, particularly when our attention is focused on something else. The failure to notice unexpected objects or events when attention is focused elsewhere is now known as inattentional blindness. The study of such failures of awareness has a long history, but their practical importance has received increasing attention over the past decade. This module describes the history and status of research on inattentional blindness, discusses the reasons why we find these results to be counterintuitive, and the implications of failures of awareness for how we see and act in our world.

Abnormal Psychology is an Open Education Resource written by Alexis Bridley, Ph.D. and Lee W. Daffin Jr., Ph.D. through Washington State University. The book tackles the difficult topic of mental disorders in 15 modules. This journey starts by discussing what abnormal behavior is by attempting to understand what normal behavior is. Models of abnormal psychology and clinical assessment, diagnosis, and treatment are then discussed. With these three modules completed, the authors next explore several classes of mental disorders in 5 blocks. Block 1 covers mood, trauma and stressor related, and dissociative disorders. Block 2 covers anxiety, somatic symptom, and obsessive-compulsive disorders. Block 3 covers eating and substance-related and addictive disorders. Block 4 tackles schizophrenia spectrum and personality disorders. Finally, Block 5 investigates neurocognitive disorders and then ends with a discussion of contemporary issues in psychopathology. Disorders are covered by discussing their clinical presentation and DSM Criteria, epidemiology, comorbidity, etiology, and treatment options.

This introductory text has been created from a combination of original content and materials compiled and adapted from a number of open text publications.

Psychology students often find statistics courses to be different from their other psychology classes. There are some distinct differences, especially involving study strategies for class success. The first difference is learning a new vocabulary—it is similar to learning a new language. Knowing the meaning of certain words will help as you are reading the material and working through the problems. Secondly, practice is critical for success; reading over the material is not enough. Statistics is a subject learned by doing, so make sure you work through any homework questions, chapter questions, and practice problems available. Lastly, we recommend that you ask questions and get help from your instructor when needed. Struggling with the course material can be frustrating, and frustration is your enemy. Often your instructor can get you back on track quickly.

Learning Statistics with R covers the contents of an introductory statistics class, as typically taught to undergraduate psychology students, focusing on the use of the R statistical software. The book discusses how to get started in R as well as giving an introduction to data manipulation and writing scripts. From a statistical perspective, the book discusses descriptive statistics and graphing first, followed by chapters on probability theory, sampling and estimation, and null hypothesis testing. After introducing the theory, the book covers the analysis of contingency tables, t-tests, ANOVAs and regression. Bayesian statistics are covered at the end of the book.

Written by Lansing Community College Psychology professor Dr. Mark Kelland, this book covers general personality theory, with an emphasis on cultural aspects affecting personality development. There is also a section focusing on making positive choices in the development of one's personality from a number of different cultural/philosophical perspectives.

Psychology 2e is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.

The second edition contains detailed updates to address comments and suggestions from users. Significant improvements and additions were made in the areas of research currency, diversity and representation, and the relevance and recency of the examples. Many concepts were expanded or clarified, particularly through the judicious addition of detail and further explanation where necessary. Finally, the authors addressed the replication issues in the psychology discipline, both in the research chapter and where appropriate throughout the book.

Changes made in Psychology 2e are described in the preface to help instructors transition to the second edition. The first edition of Psychology by OpenStax is available in web view here.

The first chapter provides an overview of the textbook and reviews the history of psychology and its methodology. Psychology is described as a science studying how hereditary (nature) and experiential (nurture) variables interact to influence the thoughts, feelings, and behavior of individuals. The remainder of the text will be organized in sections entitled “Mostly Nature” (Biological Psychology; Sensation & Perception; Motivation & Emotion), “Mostly Nurture” (Direct Learning; Indirect Learning (i.e., observational learning and language); Cognition), and “Nature/Nurture” (Human Development; Personality; Social Psychology; Maladaptive Behavior; Professional Psychology and Human Potential).

Provides standard introduction to psychology course content with a specific emphasis on social aspects of psychology. This includes expanded content related to social cognition, aggression, attraction and similar topics.

To center a variable in regression means to set its value at zero and interpret all other values in relation to this reference point. Regarding race and gender, researchers often center male and White at zero. Further, it is typical that research vignettes in statistics textbooks are similarly seated in a White, Western (frequently U.S.), heteronormative, framework. ReCentering Psych Stats seeks provide statistics training for psychology students (undergraduate, graduate, and post-doctoral) in a socially and culturally responsive way. All lessons use the open-source statistics program, R (and its associated packages). Each lesson includes a chapter and screencasted lesson, features a workflow for statistical decision-making, and includes all R code necessary to conduct the statistic. Research vignettes are drawn from the published psychology literature. When possible, these articles are authored by individuals who hold identities that have, been marginalized in the scientific literature; correctly use the statistic that is being taught in the lesson; and focus on issues of justice, equity, inclusion, or and diversity. When possible, lessons include interviews with researchers from the featured vignettes. Each chapter includes suggestions for practice that are graded in complexity, such that learners can choose the degree of challenge. ReCentering Psych Stats is perpetually-in-progress; suggestions for corrections or chapters are welcomed: ReCenteringPsychStats@spu.edu

The purpose of this project was to create a set of ancillary materials for the open textbook Research Methods in Psychology, a textbook intended to be used for psychology research methods courses. At the start of this grant, the textbook was available through the University of Minnesota’s Open Textbook Library (open.lib.umn.edu/psychologyresearchmethods/) and could be found in most open material repositories. Since this grant was proposed, however, a more recent version of the text has been released by Price, Jhangiani, Chiang, Leighton, and Cuttler (https://opentext.wsu.edu/carriecuttler/). The resources developed for this grant can be used for the new edition of the text, although they were written for the earlier version.
