Widely accepted as a low-cost, fast-turnaround solution with acceptable validity, Amazon's Mechanical Turk (MTurk) is increasingly being used to source participants for academic studies. Yet two commonly raised concerns remain: the presence of quasi-professional respondents, or “Super-Turkers”, and the presence of “Spammers”, those that compromise quality while optimising their pay rate. We isolate the influence on research results of experienced subjects (Super-Turkers), and of unreliable subjects (Spammers), jointly and separately. Jointly including these subjects produces very similar results to jointly excluding them, yet effect sizes decrease disproportionately to their sample representation. Furthermore, separately including experienced subjects in research results is shown to be as problematic as inclusion of unreliable subjects, although the noise introduced by these subjects is divergent and measure dependent. Hence removing only one of these types of respondents can be even more damaging to the reliability of results, than including both.

A venture into the art and science of measuring religion in everyday life In an era of rapid technological advances, the measures and methods used to generate data about religion have undergone remarkably little change. Faithful Measures pushes the study of religion into the 21st century by evaluating new and existing measures of religion and introducing new methods for tapping into religious behaviors and beliefs. This book offers a global and innovative approach, with chapters on the intersection of religion and new technology, such as smart phone apps, Google Ngrams, crowdsourcing data, and Amazon buying networks. It also shows how old methods can be improved by using new technology to create online surveys with experimental designs and by developing new ways of mining data from existing information. Chapter contributors thoroughly explain how to employ these new techniques, and offer fresh insights into understanding the complex topic of religion in modern life. Beyond its quantitative contributions, Faithful Measures will be an invaluable resource for inspiring a new wave of creativity and exploration in our connected world.

What impact can various research methods have on consumer psychology? How can they help us understand the workings of the consumer mind? And how can the field of consumer psychology best utilize these methods? In the Handbook of Research Methods in Consumer Psychology, leading consumer psychologists summarize key aspects of the research process and explain how different methods enrich understanding of how consumers process information to form judgments and opinions and to make consumption-related decisions. Kardes, Herr, and Schwarz provide an in-depth analysis of the scientific research methods needed to understand consumption-related judgments and decisions. The book is split into five parts, demonstrating the breadth of the volume: classic approaches, contemporary approaches, online research methods, data analysis, and philosophy of science. A variety of leading researchers give insight into a wide range of topics, reflecting both long-standing debate and more recent developments in the field to encourage discussion and the advancement of consumer research. The Handbook of Research Methods in Consumer Psychology is essential reading for researchers, students, and professionals interested in consumer psychology and behavior.

The Dark Triad of Personality: Narcissism, Machiavellianism, and Psychopathy in Everyday Life summarizes the latest research on how these personality traits (psychopathology, narcissism, Machiavellianism) are defined and displayed, while also exploring the impact they have on individuals and society, the relationship between clinical conditions and personality traits, and their adaptivity. The book introduces the Dark Triad through the lens of existing clinical and personality literature, discussing shared and unique cognitive and empathetic profiles associated with each trait. Antisocial, antagonistic, and criminal behaviors associated with the Dark Triad are also covered, as is the way these individuals compete socially and in the workplace. - Reviews the development, measurement and evolutionary origins of these traits - Explores how these traits may be adaptive - Assesses the relationship between clinical conditions and Dark Triad personality traits - Includes sections on manipulation, competition and cooperation

This book tackles a subject that has captured the imagination of many researchers in the field: attitudes. Although the field has always recognized that people‘s attitudes could be assessed in different ways, from direct self-reports to disguised observations of behavior, the past decade has shown several new approaches to attitude measurement. Des

Dark personality traits, and traits with dark features, are connected to destructive behaviors and interpersonal problems. Even moderate levels of these traits can cause significant issues. Understanding them will play an integral role in treating individuals who exhibit dark, unhealthy characteristics. Thus, a primary goal of this book is to unite personality psychology and clinical psychology. It synthesizes recent research that connects pathological personality features to the Big Five personality dimensions, creating an interdisciplinary taxonomy of dark personality traits. This volume brings together a diverse panel of experts who provide complex, nuanced perspectives on a variety of personality traits, including those that are readily accepted as dark (e.g., the Dark Triad of narcissism, psychopathy, and Machiavellianism), have been largely ignored by the broader psychological literature (e.g., spitefulness), have not been included in previous discussions of dark personality traits (e.g., authoritarianism), or appear to be at least somewhat positive on a superficial level (e.g., perfectionism and fearless dominance). Chapters explore both maladaptive and adaptive features of these traits, including how to address them in clinical settings. The final chapter ties the entire volume together with a thorough review of common themes, clinical implications, and research goals across all traits.

Although sexuality is an integral part of close romantic relationships, research linking these two constructs has been less systematic than other areas pertaining to close relationships. To date, researchers in communication, sociology, family studies, psychology, and psychiatry, have made significant advances in both of these fields. The editors' goal is to integrate this research into one volume. They bring together major scholars from the diversity of fields working on close relationship topics to examine past contributions and new directions in sexuality. The emphasis is on theoretical integration and stimulation, methodological rigor, and critical analysis. This volume explores: *early sexual experiences and their impact on late life sexuality; *how life's stresses impact sexuality and satisfaction with closeness; *the affect of postpartum depression on sexuality; and *the relationship between control, power, anger, as well as revenge and sexual processes in couples. The Handbook of Sexuality in Close Relationships is intended for students and researchers in the disciplines of social, clinical, developmental, and health psychology; family studies; counseling; and interpersonal, family, and health communication. An excellent reference in advanced courses in close relationships taught in psychology, communications, sociology, anthropology, and family studies, the material in Part V will also appeal to clinical psychologists, health professionals, and policymakers.
