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.
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.
In the analysis of multivariate observations designed to assess subjects with respect to an attribute, a Guttman scale is a single (unidimensional) ordinal scale for the assessment of the attribute, from which the original observations may be reproduced. The discovery of a Guttman scale in data depends on their multivariate distribution's conforming to a particular structure. Hence, a Guttman scale is a hypothesis about the structure of the data, formulated with respect to a specified attribute and a specified population and cannot be constructed for any given set of observations. Contrary to a widespread belief, a Guttman scale is not limited to dichotomous variables and does not necessarily determine an order among the variables. But if variables are all dichotomous, the variables are indeed ordered by their sensitivity in recording the assessed attribute, as illustrated by Example 1.
Raymond Bernard Cattell was a British-American psychologist, known for his psychometric research into intrapersonal psychological structure. His work also explored the basic dimensions of personality and temperament, the range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of abnormal personality, patterns of group syntality and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains. Cattell authored, co-authored, or edited almost 60 scholarly books, more than 500 research articles, and over 30 standardized psychometric tests, questionnaires, and rating scales. According to a widely cited ranking, Cattell was the 16th most eminent, 7th most cited in the scientific journal literature, and among the most productive psychologists of the 20th century. He was a controversial figure due in part to his friendships with, and intellectual respect for, white supremacists and neo-Nazis.
Jane LoevingerWeissman was an American developmental psychologist who developed a theory of personality which emphasized the gradual internalization of social rules and the maturing conscience for the origin of personal decisions. She also contributed to the theory of measurements by introducing the coefficient of test homogeneity. In the tradition of developmental stage models, Loevinger integrated several "frameworks of meaning-making" into a model of humans' constructive potentials that she called ego development. The essence of the ego is the striving to master, to integrate, and make sense of experience. She also is credited with the creation of an assessment test, the Washington University Sentence Completion Test.
Seymour Bernard Sarason was Professor of Psychology Emeritus at Yale University, where he taught from 1945 to 1989. He is the author of over forty books and over sixty articles, and he is considered to be one of the most significant American researchers in education, educational psychology, and community psychology. One primary focus of his work was on education reform in the United States. In the 1950s he and George Mandler initiated the research on test anxiety. He founded the Yale Psycho-Educational Clinic in 1961 and was one of the principal leaders in the community psychology movement. In 1974, he proposed psychological sense of community, a central concept in community psychology. Since then, sense of community has become a well-known and commonly used term both in academic and non-academic settings.
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.
An ink blot test is a personality test that involves the evaluation of a subject's response to ambiguous ink blots. This test was published in 1921 by Swiss psychiatrist Hermann Rorschach. The interpretation of people's responses to the Rorschach Inkblot Test was originally based on psychoanalytical theory but investigators have used it in an empirical fashion. When this test is used empirically, the quality of the responses is related to the measurements of personality.
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 Animal Metaphor Test is a projective psychological test created by Albert J. Levis, the director and founder of the Museum of the Creative Process, in 1988. The Animal Metaphor Test is one of many tests that are part of Levis' Conflict Analysis Battery, a collection of psychological tests.
The Rorschach Performance Assessment System (R-PAS) is a scoring and interpretive method to be used with the Rorschach inkblot test. This system is being developed by several members of the Rorschach Research Council, a group established by John Exner to advance the research on the Comprehensive System, the most widely used scoring system for the Rorschach. Following Exner's death, the council admitted that the current Comprehensive System scoring was in need of revision. R-PAS was developed as an empirically based revision of the Exner Comprehensive System.
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.
