Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to 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:
In personality typology, the Myers–Briggs Type Indicator (MBTI) is an introspective self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. It enjoys popularity despite being widely regarded as pseudoscience by the scientific community. The test attempts to assign a binary value to each of four categories: introversion or extraversion, sensing or intuition, thinking or feeling, and judging or perceiving. One letter from each category is taken to produce a four-letter test result representing one of sixteen possible personalities, such as "ISTJ" or "ENFP".
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 career is an individual's metaphorical "journey" through learning, work and other aspects of life. There are a number of ways to define career and the term is used in a variety of ways.
Clinical psychology is an integration of human science, behavioral science, theory, and clinical knowledge for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development. Central to its practice are psychological assessment, clinical formulation, and psychotherapy, although clinical psychologists also engage in research, teaching, consultation, forensic testimony, and program development and administration. In many countries, clinical psychology is a regulated mental health profession.
Counseling psychology is a psychological specialty that began with a focus on vocational counseling, but later moved its emphasis to adjustment counseling, and then expanded to cover all normal psychology psychotherapy. There are many subcategories for counseling psychology, such as marriage and family counseling, rehabilitation counseling, clinical mental health counseling, educational counseling, etc. In each setting, they are all required to follow the same guidelines.
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.
Learning styles refer to a range of theories that aim to account for differences in individuals' learning. Although there is ample evidence that individuals express personal preferences for how they prefer to receive information, few studies have found any validity in using learning styles in education. Many theories share the proposition that humans can be classified according to their "style" of learning, but differ in how the proposed styles should be defined, categorized and assessed. A common concept is that individuals differ in how they learn.
Personnel selection is the methodical process used to hire individuals. Although the term can apply to all aspects of the process the most common meaning focuses on the selection of workers. In this respect, selected prospects are separated from rejected applicants with the intention of choosing the person who will be the most successful and make the most valuable contributions to the organization. Its effect on the group is discerned when the selected accomplish their desired impact to the group, through achievement or tenure. The procedure of selection takes after strategy to gather data around a person so as to figure out whether that individual ought to be utilized. The strategies used must be in compliance with the various laws in respect to work force selection.
The Strong Interest Inventory (SII) is an interest inventory used in career assessment. As such, career assessments may be used in career counseling. The goal of this assessment is to give insight into a person's interests, so that they may have less difficulty in deciding on an appropriate career choice for themselves. It is also frequently used for educational guidance as one of the most popular career assessment tools. The test was developed in 1927 by psychologist Edward Kellog Strong, Jr. to help people exiting the military find suitable jobs. It was revised later by Jo-Ida Hansen and David P. Campbell. The modern version of 2004 is based on the Holland Codes typology of psychologist John L. Holland. The Strong is designed for high school students, college students, and adults, and was found to be at about the ninth-grade reading level.
Career counseling is a type of advice-giving and support provided by career counselors to their clients, to help the clients manage their journey through life, learning and work changes (career). This includes career exploration, making career choices, managing career changes, lifelong career development and dealing with other career-related issues. There is no agreed definition of the role of a career or employment counsellor worldwide, mainly due to conceptual, cultural and linguistic differences. However, the terminology of 'career counseling' typically denotes a professional intervention which is conducted either one-on-one or in a small group. Career counseling is related to other types of counseling. What unites all types of professional counseling is the role of practitioners, who combine giving advice on their topic of expertise with counseling techniques that support clients in making complex decisions and facing difficult situations.
A situational judgement test (SJT), or situational stress test (SStT) or inventory (SSI) is a type of psychological test which presents the test-taker with realistic, hypothetical scenarios and ask them to identify the most appropriate response or to rank the responses in the order they feel is most effective. SJTs can be presented to test-takers through a variety of modalities, such as booklets, films, or audio recordings. SJTs represent a distinct psychometric approach from the common knowledge-based multiple choice item. They are often used in industrial-organizational psychology applications such as personnel selection. Situational judgement tests tend to determine behavioral tendencies, assessing how an individual will behave in a certain situation, and knowledge instruction, which evaluates the effectiveness of possible responses. Situational judgement tests could also reinforce the status quo with an organization.
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.
Psychological evaluation is a method to assess an individual's behavior, personality, cognitive abilities, and several other domains. A common reason for a psychological evaluation is to identify psychological factors that may be inhibiting a person's ability to think, behave, or regulate emotion functionally or constructively. It is the mental equivalent of physical examination. Other psychological evaluations seek to better understand the individual's unique characteristics or personality to predict things like workplace performance or customer relationship management.
In the United States education system, School Psychological Examiners assess the needs of students in schools for special education services or other interventions. The post requires a relevant postgraduate qualification and specialist training. This role is distinct within school psychology from that of the psychiatrist, clinical psychologist and psychometrist.
Anne Anastasi was an American psychologist best known for her pioneering development of psychometrics. Her generative work, Psychological Testing, remains a classic text in which she drew attention to the individual being tested and therefore to the responsibilities of the testers. She called for them to go beyond test scores, to search the assessed individual's history to help them to better understand their own results and themselves.
Individual psychological assessment (IPA) is a tool used by organizations to make decisions on employment. IPA allows employers to evaluate and maintain potential candidates for hiring, promotion, and development by using a series of job analysis instruments such as position analysis questionnaires (PAQ), occupational analysis inventory (OAI), and functional job analysis (FJA). These instruments allow the assessor to develop valid measures of intelligence, personality tests, and a range of other factors as means to determine selection and promotion decisions. Personality and cognitive ability are good predictors of performance. Emotional Intelligence helps individuals navigate through challenging organizational and interpersonal encounters. Since individual differences have a long history in explaining human behavior and the different ways in which individuals respond to similar events and circumstances, these factors allow the organization to determine if an applicant has the competence to effectively and successfully do the work that the job requires. These assessments are administered throughout organizations in different forms, but they share one common goal in the selection process, and that is the right candidate for the job.
A pre-hire assessment is a test or questionnaire that candidates complete as part of the job application process. The use of a valid and expert assessment is an effective way to determine which applicants are the most qualified for a specific job based on their strengths and preferences. Employers typically use the results to determine how well each candidate's strengths and preferences match the job requirements.
Walter Van Dyke Bingham (1880–1952) was an applied and industrial psychologist who made significant contributions to intelligence testing. A pioneer in applied psychology, Bingham got his start in experimental psychology, receiving his Ph.D. at the University of Chicago under James R. Angell. Bingham went from Dartmouth in 1915 to organize the Division of Applied Psychology at the Carnegie Institute of Technology. When war came to the United States, Bingham was recruited by Robert Yerkes as a member of a small group that developed the Army Alpha and Beta tests. During World War I Bingham served as executive secretary of the committee on classification of personnel in the U.S. Army, and later in the war served as lieutenant colonel in the Personnel Branch of the Army General Staff. From 1940 to 1947 Bingham was chief psychologist of the Adjutant General's Office of the War Department, serving as consultant or advisor to the Surgeon General, the Army General Staff, and the Secretary of Defense. Walter Bingham's contribution on the army classification methods paved the development of the field of industrial psychology. Bingham carried out editorial responsibilities for several journals and was the author of over 200 articles and books. His "Aptitude and Aptitude Testing" (1937/1942) is a classic in the field.
