Psychology is the study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological 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.
Personality psychology is a branch of psychology that examines personality and its variation among individuals. It aims to show how people are individually different due to psychological forces. Its areas of focus include:
Personality is any person's collection of interrelated behavioral, cognitive and emotional patterns that comprise a person’s unique adjustment to life. These interrelated patterns are relatively stable, but can change over long time periods.
In social psychology, self-assessment is the process of looking at oneself in order to assess aspects that are important to one's identity. It is one of the motives that drive self-evaluation, along with self-verification and self-enhancement. Sedikides (1993) suggests that the self-assessment motive will prompt people to seek information to confirm their uncertain self-concept rather than their certain self-concept and at the same time people use self-assessment to enhance their certainty of their own self-knowledge. However, the self-assessment motive could be seen as quite different from the other two self-evaluation motives. Unlike the other two motives, through self-assessment people are interested in the accuracy of their current self view, rather than improving their self-view. This makes self-assessment the only self-evaluative motive that may cause a person's self-esteem to be damaged.
Gordon Willard Allport was an American psychologist. Allport was one of the first psychologists to focus on the study of the personality, and is often referred to as one of the founding figures of personality psychology. He contributed to the formation of values scales and rejected both a psychoanalytic approach to personality, which he thought often was too deeply interpretive, and a behavioral approach, which he thought did not provide deep enough interpretations from their data. Instead of these popular approaches, he developed an eclectic theory based on traits. He emphasized the uniqueness of each individual, and the importance of the present context, as opposed to history, for understanding the personality.
Delayed gratification, or deferred gratification, is the resistance to the temptation of an immediate pleasure in the hope of obtaining a valuable and long-lasting reward in the long-term. In other words, delayed gratification describes the process that the subject undergoes when the subject resists the temptation of an immediate reward in preference for a later reward that is more favorable. Generally, delayed gratification is associated with resisting a smaller but more immediate reward in order to receive a larger or more enduring reward later. A growing body of literature has linked the ability to delay gratification to a host of other positive outcomes, including academic success, physical health, psychological health, and social competence.
Walter Mischel was an Austrian-born American psychologist specializing in personality theory and social psychology. He was the Robert Johnston Niven Professor of Humane Letters in the Department of Psychology at Columbia University. A Review of General Psychology survey, published in 2002, ranked Mischel as the 25th most cited psychologist of the 20th century.
Carl Emil Seashore, born Sjöstrand was a prominent American psychologist and educator. He was the author of numerous books and articles principally regarding the fields of speech–language pathology, music education, and the psychology of music and art. He served as Dean of the Graduate College of University of Iowa from 1908–1937. He is most commonly associated with the development of the Seashore Tests of Musical Ability.
Implicit personality theory describes the specific patterns and biases an individual uses when forming impressions based on a limited amount of initial information about an unfamiliar person. While there are parts of the impression formation process that are context-dependent, individuals also tend to exhibit certain tendencies in forming impressions across a variety of situations. There is not one singular implicit personality theory utilized by all; rather, each individual approaches the task of impression formation in his or her own unique way. However, there are some components of implicit personality theories that are consistent across individuals, or within groups of similar individuals. These components are of particular interest to social psychologists because they have the potential to give insight into what impression one person will form of another.
Social perception is the study of how people form impressions of and make inferences about other people as sovereign personalities. Social perception refers to identifying and utilizing social cues to make judgments about social roles, rules, relationships, context, or the characteristics of others. This domain also includes social knowledge, which refers to one's knowledge of social roles, norms, and schemas surrounding social situations and interactions. People learn about others' feelings and emotions by picking up information they gather from physical appearance, verbal, and nonverbal communication. Facial expressions, tone of voice, hand gestures, and body position or movement are a few examples of ways people communicate without words. A real-world example of social perception is understanding that others disagree with what one said when one sees them roll their eyes. There are four main components of social perception: observation, attribution, integration, and confirmation.
Negative affectivity (NA), or negative affect, is a personality variable that involves the experience of negative emotions and poor self-concept. Negative affectivity subsumes a variety of negative emotions, including anger, contempt, disgust, guilt, fear, and nervousness. Low negative affectivity is characterized by frequent states of calmness and serenity, along with states of confidence, activeness, and great enthusiasm.
Thin-slicing is a term used in psychology and philosophy to describe the ability to find patterns in events based only on "thin slices", or narrow windows, of experience. The term refers to the process of making very quick inferences about the state, characteristics or details of an individual or situation with minimal amounts of information. Research has found that brief judgments based on thin-slicing are similar to those judgments based on much more information. Judgments based on thin-slicing can be as accurate, or even more so, than judgments based on much more information.
Interpersonal perception is an area of research in social psychology which examines the beliefs that interacting people have about each other. This area differs from social cognition and person perception by being interpersonal rather than intrapersonal, and thus requiring the interaction of at least two actual people. There are three stages of the perception process including selection, organization, and interpretation.
Douglas T. Kenrick is professor of psychology at Arizona State University. His research and writing integrate three scientific syntheses of the last few decades: evolutionary psychology, cognitive science, and dynamical systems theory. He is author of over 170 scientific articles, books, and book chapters, the majority applying evolutionary ideas to human cognition and behavior.
The Stanford marshmallow experiment was a study on delayed gratification in 1970 led by psychologist Walter Mischel, a professor at Stanford University In this study, a child was offered a choice between one small but immediate reward, or two small rewards if they waited for a period of time. During this time, the researcher left the child in a room with a single marshmallow for about 15 minutes and then returned. If they did not eat the marshmallow, the reward was either another marshmallow or pretzel stick, depending on the child's preference. In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures. A replication attempt with a sample from a more diverse population, over 10 times larger than the original study, showed only half the effect of the original study. The replication suggested that economic background, rather than willpower, explained the other half. The predictive power of the marshmallow test was challenged in a 2020 study.
The person–situation debate in personality psychology refers to the controversy concerning whether the person or the situation is more influential in determining a person's behavior. Personality trait psychologists believe that a person's personality is relatively consistent across situations. Situationists, opponents of the trait approach, argue that people are not consistent enough from situation to situation to be characterized by broad personality traits. The debate is also an important discussion when studying social psychology, as both topics address the various ways a person could react to a given situation.
Personality judgment is the process by which people perceive each other's personalities through acquisition of certain information about others, or meeting others in person. The purpose of studying personality judgment is to understand past behavior exhibited by individuals and predict future behavior. Theories concerning personality judgment focus on the accuracy of personality judgments and the effects of personality judgments on various aspects of social interactions. Determining how people judge personality is important because personality judgments often influence individuals' behaviors.
Paul J. Moses was a clinical professor in charge of the Speech and Voice Section, Division of Otolaryngology at the Stanford University School of Medicine, San Francisco, where he conducted research into the psychology of the human voice, seeking to show how personality traits, neuroses, and symptoms of mental disorders are evident in the vocal tone or pitch range, prosody, and timbre of a voice, independent of the speech content.
A zero-acquaintance situation requires a perceiver to make a judgment about a target with whom the perceiver has had no prior social interaction. These judgments can be made using a variety of cues, including brief interactions with the target, video recordings of the target, photographs of the target, and observations of the target's personal environments, among others. In zero-acquaintance studies, the target's actual personality is determined through the target's self-rating and/or ratings from close acquaintance(s) of that target. Consensus in ratings is determined by how consistently perceivers rate the target's personality when compared to other raters. Accuracy in ratings is determined by how well perceivers' ratings of a target compare to that target's self-ratings on the same scale, or to that target's close acquaintances' ratings of the target. Zero-acquaintance judgments are regularly made in day-to-day life. Given that these judgments tend to remain stable, even as the length of interaction increases, they can influence important interpersonal outcomes.
Marvin Zuckerman was Professor Emeritus of Psychology at the University of Delaware. Zuckerman is best known for his research into the psychobiological basis of human personality, sensory deprivation, mood state measurement, and sensation seeking. His work was particularly inspired by eminent research psychologists, Hans Eysenck and Arnold Buss.
