Psychology is the study of mind and behavior in humans and non-humans. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.
Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people or by social norms. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions.
Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method. For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated. There are different kinds of replication but typically replication studies involve different researchers using the same methodology. Only after successful replications should a result be recognized as scientific knowledge.
In psychology, illusory correlation is the phenomenon of perceiving a relationship between variables even when no such relationship exists. A false association may be formed because rare or novel occurrences are more salient and therefore tend to capture one's attention. This phenomenon is one way stereotypes form and endure. Hamilton & Rose (1980) found that stereotypes can lead people to expect certain groups and traits to fit together, and then to overestimate the frequency with which these correlations actually occur. These stereotypes can be learned and perpetuated without any actual contact occurring between the holder of the stereotype and the group it is about.
The implicit-association test (IAT) is an assessment intended to detect subconscious associations between mental representations of objects (concepts) in memory. Its best-known application is the assessment of implicit stereotypes held by test subjects, such as associations between particular racial categories and stereotypes about those groups. The test has been applied to a variety of belief associations, such as those involving racial groups, gender, sexuality, age, and religion but also the self-esteem, political views, and predictions of the test taker. The implicit-association test is the subject of significant academic and popular debate regarding its validity, reliability, and usefulness in assessing implicit bias.
Mahzarin Rustum Banaji FBA is an American psychologist of Indian origin at Harvard University, known for her work popularizing the concept of implicit bias in regard to race, gender, sexual orientation, and other factors.
The Journal of Personality and Social Psychology is a monthly peer-reviewed scientific journal published by the American Psychological Association that was established in 1965. It covers the fields of social and personality psychology. The editors-in-chief are Shinobu Kitayama, Colin Wayne Leach, and Richard E. Lucas.
Carol Susan Dweck is an American psychologist. She holds the Lewis and Virginia Eaton Professorship of Psychology at Stanford University. Dweck is known for her work on motivation and mindset. She was on the faculty at the University of Illinois, Harvard, and Columbia before joining the Stanford University faculty in 2004. She was named an Association for Psychological Science (APS) James McKeen Cattell Fellow in 2013, an APS Mentor Awardee in 2019, and an APS William James Fellow in 2020, and has been a member of the National Academy of Sciences since 2012.
Laurie A. Rudman is a social psychology feminist professor as well as the Director of the Rutgers University Social Cognition Laboratory who has contributed a great deal of research to studies on implicit and explicit attitudes and stereotypes, stereotype maintenance processes, and the media's effects on attitudes, stereotypes, and behavior on the Feminism movement. She was awarded the 1994 Gordon Allport Intergroup Relations Prize for her research examining the effects of sexist advertising on men's behavior toward female job applicants.
Anthony Galt Greenwald is a social psychologist and, since 1986, he is aprofessor of psychology at University of Washington.
The decline effect may occur when scientific claims receive decreasing support over time. The term was first described by parapsychologist Joseph Banks Rhine in the 1930s to describe the disappearing of extrasensory perception (ESP) of psychic experiments conducted by Rhine over the course of study or time. In its more general term, Cronbach, in his review article of science "Beyond the two disciplines of scientific psychology" referred to the phenomenon as "generalizations decay." The term was once again used in a 2010 article by Jonah Lehrer published in The New Yorker.
An implicit bias or implicit stereotype is the pre-reflective attribution of particular qualities by an individual to a member of some social out group.
Amy Joy Casselberry Cuddy is an American social psychologist, author and speaker. She is a proponent of "power posing", a self-improvement technique whose scientific validity has been questioned. She has served as a faculty member at Rutgers University, Kellogg School of Management and Harvard Business School. Cuddy's most cited academic work involves using the stereotype content model that she helped develop to better understand the way people think about stereotyped people and groups. Though Cuddy left her tenure-track position at Harvard Business School in the spring of 2017, she continues to contribute to its executive education programs.
The Center for Open Science is a non-profit technology organization based in Charlottesville, Virginia with a mission to "increase the openness, integrity, and reproducibility of scientific research." Brian Nosek and Jeffrey Spies founded the organization in January 2013, funded mainly by the Laura and John Arnold Foundation and others.
The replication crisis is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge.
The Reproducibility Project is a series of crowdsourced collaborations aiming to reproduce published scientific studies, finding high rates of results which could not be replicated. It has resulted in two major initiatives focusing on the fields of psychology and cancer biology. The project has brought attention to the replication crisis, and has contributed to shifts in scientific culture and publishing practices to address it.
Metascience is the use of scientific methodology to study science itself. Metascience seeks to increase the quality of scientific research while reducing inefficiency. It is also known as "research on research" and "the science of science", as it uses research methods to study how research is done and find where improvements can be made. Metascience concerns itself with all fields of research and has been described as "a bird's eye view of science". In the words of John Ioannidis, "Science is the best thing that has happened to human beings ... but we can do it better."
Intergroup relations refers to interactions between individuals in different social groups, and to interactions taking place between the groups themselves collectively. It has long been a subject of research in social psychology, political psychology, and organizational behavior.
Preregistration is the practice of registering the hypotheses, methods, and/or analyses of a scientific study before it is conducted. Clinical trial registration is similar, although it may not require the registration of a study's analysis protocol. Finally, registered reports include the peer review and in principle acceptance of a study protocol prior to data collection.
Crowdsourced science refers to collaborative contributions of a large group of people to the different steps of the research process in science. In psychology, the nature and scope of the collaborations can vary in their application and in the benefits it offers.
