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.
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales.
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:
Psychological testing refers to the administration of psychological tests. Psychological tests are administered or scored by trained evaluators. A person's responses are evaluated according to carefully prescribed guidelines. Scores are thought to reflect individual or group differences in the construct the test purports to measure. The science behind psychological testing is psychometrics.
The Rorschach test is a projective psychological test in which subjects' perceptions of inkblots are recorded and then analyzed using psychological interpretation, complex algorithms, or both. Some psychologists use this test to examine a person's personality characteristics and emotional functioning. It has been employed to detect underlying thought disorder, especially in cases where patients are reluctant to describe their thinking processes openly. The test is named after its creator, Swiss psychologist Hermann Rorschach. The Rorschach can be thought of as a psychometric examination of pareidolia, the active pattern of perceiving objects, shapes, or scenery as meaningful things to the observer's experience, the most common being faces or other pattern of forms that are not present at the time of the observation. In the 1960s, the Rorschach was the most widely used projective test.
Thematic apperception test (TAT) is a projective psychological test developed during the 1930s by Henry A. Murray and Christiana D. Morgan at Harvard University. Proponents of the technique assert that subjects' responses, in the narratives they make up about ambiguous pictures of people, reveal their underlying motives, concerns, and the way they see the social world. Historically, the test has been among the most widely researched, taught, and used of such techniques.
A personality test is a method of assessing human personality constructs. Most personality assessment instruments are in fact introspective self-report questionnaire measures or reports from life records (L-data) such as rating scales. Attempts to construct actual performance tests of personality have been very limited even though Raymond Cattell with his colleague Frank Warburton compiled a list of over 2000 separate objective tests that could be used in constructing objective personality tests. One exception however, was the Objective-Analytic Test Battery, a performance test designed to quantitatively measure 10 factor-analytically discerned personality trait dimensions. A major problem with both L-data and Q-data methods is that because of item transparency, rating scales and self-report questionnaires are highly susceptible to motivational and response distortion ranging all the way from lack of adequate self-insight to downright dissimulation depending on the reason/motivation for the assessment being undertaken.
Hermann Rorschach was a Swiss psychiatrist and psychoanalyst. His education in art helped to spur the development of a set of inkblots that were used experimentally to measure various unconscious parts of the subject's personality. His method has come to be referred to as the Rorschach test, iterations of which have continued to be used over the years to help identify personality, psychotic, and neurological disorders. Rorschach continued to refine the test until his premature death at age 37.
In psychology, a projective test is a personality test designed to let a person respond to ambiguous stimuli, presumably revealing hidden emotions and internal conflicts projected by the person into the test. This is sometimes contrasted with a so-called "objective test" / "self-report test", which adopt a "structured" approach as responses are analyzed according to a presumed universal standard, and are limited to the content of the test. The responses to projective tests are content analyzed for meaning rather than being based on presuppositions about meaning, as is the case with objective tests. Projective tests have their origins in psychoanalysis, which argues that humans have conscious and unconscious attitudes and motivations that are beyond or hidden from conscious awareness.
The Holtzman inkblot technique (HIT), also known as the Holtzman inkblot test, is an ink blot test aimed at detecting personality and was conceived by Wayne H. Holtzman and colleagues. It was first introduced in 1961 as a projective personality test similar to the Rorschach. The HIT is a standardized measurement. The Holtzman Inkblot Test was developed as an attempt to address some controversial issues surrounding the Rorschach Inkblot Test.
Bruno Klopfer was a German psychologist, born in Bavaria.
Psychogram is a term sometimes used in fields within psychology such as personality theory and perception as well as graphology and handwriting analysis, although the term has multiple senses, many of them outdated, and none of the senses of the term are defined clearly or used consistently.
John E. Exner, Jr., born in Syracuse, New York, was an American psychologist. He received a BS and an MS degree in psychology from Trinity University and a PhD in clinical psychology from Cornell University in 1958. From 1968 to 1969 he served as a director for the East Asia/Pacific and North Africa, Near East, South Asia Regions of the Office of Selection, Peace Corps of the United States of America. Later he became a faculty member at Long Island University, where he was director of clinical training from 1969 to 1979. He became professor emeritus in 1984.
The Blacky pictures test was a projective test, employing a series of twelve picture cards, used by psychoanalysts in mid-20th century America and elsewhere, to investigate the extent to which children's personalities were shaped by Freudian psychosexual development.
Molly Harrower was an American clinical psychologist. During the Second World War she created a large-scale multiple choice Rorschach test. She was one of the first clinical psychologists to open a private practice. Specializing in diagnostics, Harrower developed a scale allowing practitioners to predict which patients would profit from psychotherapy.
Irving B. Weiner is an American psychologist and past president of Division 12 of the American Psychological Association. and past president of the Society for Personality Assessment. He is the author and editor of many books on psychology.
The APA Award for Distinguished Professional Contributions to Applied Research is a scientific award presented by the American Psychological Association "to a psychologist whose research has led to important discoveries or developments in the field of applied psychology."
Klecksography is the art of making images from inkblots. The work was pioneered by Justinus Kerner, who included klecksographs in his books of poetry. Since the 1890s, psychologists have used it as a tool for studying the subconscious, most famously Hermann Rorschach in his Rorschach inkblot test.
Wayne Harold Holtzman was an American psychologist best known for the development of the Holtzman Inkblot Test. Holtzman received a master's degree from Northwestern University and a doctorate from Stanford University. He worked at the University of Texas at Austin from 1949 until he retired in 1993. He developed the Holtzman Inkblot Test to address deficiencies in the Rorschach test.
Scott O. Lilienfeld was a professor of psychology at Emory University and advocate for evidence-based treatments and methods within the field. He is known for his books 50 Great Myths of Popular Psychology, Brainwashed, and others that explore and sometimes debunk psychological claims that appear in the popular press. Along with having his work featured in major U.S. newspapers and journals such as The New York Times, The New Yorker, and Scientific American, Lilienfeld made television appearances on 20/20, CNN and the CBS Evening News.
