Differential Psychology
Differential psychology studies the ways in which individuals differ in their behavior and the processes that underlie it. It is a discipline that develops classifications (Taxonomy, taxonomies) of psychological individual differences. This is distinguished from other aspects of psychology in that, although psychology is ostensibly a study of individuals, modern psychologists often study groups, or attempt to discover general psychological processes that apply to all individuals. This particular area of psychology was first named and still retains the name of "differential psychology" by William Stern (psychologist), William Stern in his 1900 book "''Über Psychologie der individuellen Differenzen''" (On the Psychology of Individual Differences). While prominent psychologists, including Stern, have been widely credited for the concept of differential psychology, historical records show that it was Charles Darwin (1859) who first spurred the scientific interest in the study of ind ...

Taxonomy
image:Hierarchical clustering diagram.png, 280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the Taxonomy (biology), classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchy, hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a Taxonomy for search e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-efficacy
In psychology, self-efficacy is an individual's belief in their capacity to act in the ways necessary to reach specific goals. The concept was originally proposed by the psychologist Albert Bandura in 1977. Self-efficacy affects every area of human endeavor. By determining the beliefs a person holds regarding their power to affect situations, self-efficacy strongly influences both the power a person actually has to face challenges competently and the choices a person is most likely to make. These effects are particularly apparent, and compelling, with regard to investment behaviors such as in health, education, and agriculture. A strong sense of self-efficacy promotes human accomplishment and personal well-being. A person with high self-efficacy views challenges as things that are supposed to be mastered rather than threats to avoid. These people are able to recover from failure faster and are more likely to attribute failure to a lack of effort. They approach threatening situatio ...

Positron Emission Tomography
Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging purposes, depending on the target process within the body, such as: * Fluorodeoxyglucose ( 18F">sup>18FDG or FDG) is commonly used to detect cancer; * 18Fodium fluoride">sup>18Fodium fluoride (Na18F) is widely used for detecting bone formation; * Oxygen-15 (15O) is sometimes used to measure blood flow. PET is a common imaging technique, a medical scintillography technique used in nuclear medicine. A radiopharmaceutical—a radioisotope attached to a drug—is injected into the body as a tracer. When the radiopharmaceutical undergoes beta plus decay, a positron is emitted, and when the positron interacts with an ordinary electron, the tw ...

Psychophysiology
Psychophysiology (from Greek , ''psȳkhē'', "breath, life, soul"; , ''physis'', "nature, origin"; and , '' -logia'') is the branch of psychology that is concerned with the physiological bases of psychological processes. While psychophysiology was a general, broad field of research in the 1960s and 1970s, it has now become quite specialized, based on methods, topic of studies, and scientific traditions. Methods vary as combinations of electrophysiological methods (such as EEG), neuroimaging ( MRI, PET), and neurochemistry. Topics have branched into subspecializations such as social, sport, cognitive, cardiovascular, clinical, and other branches of psychophysiology. Background Some people have difficulty distinguishing a psychophysiologist from a physiological psychologist, which has two very different perspectives. Psychologists are interested in why we may fear spiders and physiologists may be interested in the input/output system of the amygdala. A psychophysiologis ...

Event-related Potential
An event-related potential (ERP) is the measured brain response that is the direct result of a specific sense, sensory, cognition, cognitive, or motor system, motor event. More formally, it is any stereotyped electrophysiology, electrophysiological response to a stimulus. The study of the brain in this way provides a Invasiveness of surgical procedures, noninvasive means of evaluating brain functioning. ERPs are measured by means of electroencephalography (EEG). The magnetoencephalography (MEG) equivalent of ERP is the ERF, or event-related field. Evoked potentials and induced potentials are subtypes of ERPs. History With the discovery of the electroencephalogram (EEG) in 1924, Hans Berger revealed that one could measure the electrical activity of the human brain by placing electrodes on the scalp and amplifying the signal. Changes in voltage can then be plotted over a period of time. He observed that the voltages could be influenced by external events that stimulated the sense ...

Neo-Piagetian Theories Of Cognitive Development
Neo-Piagetian theories of cognitive development criticize and build upon Jean Piaget's theory of cognitive development. Overview The neo-Piagetian theories aim to correct one or more of the following weaknesses in Piaget's theory: * Piaget's developmental stage theory proposes that people develop through various stages of cognitive development, but his theory does not sufficiently explain why development from stage to stage occurs. Mansoor Niaz has argued that Piaget's stages were merely a heuristic for operationalizing his theory of equilibration. * Piaget's theory does not sufficiently explain individual differences in cognitive development. The theory does not account for the fact that some individuals move from stage to stage faster than other individuals. * The idea of rigid universal stages of cognitive development is incorrect. Research shows that the functioning of a person at a given age varies significantly from domain to domain (such as the understanding of social, ma ...

Developmental Psychology
Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation. Developmental psychology examines the influences of nature ''and'' nurture on the process of human development, as well as processes of change in context across time. Many researchers are interested in the interactions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Behavioral Genetics
Behavioural genetics, also referred to as behaviour genetics, is a field of scientific research that uses genetic methods to investigate the nature and origins of individual differences in behaviour. While the name "behavioural genetics" connotes a focus on genetic influences, the field broadly investigates the extent to which genetic and environmental factors influence individual differences, and the development of research designs that can remove the confounding of genes and environment. Behavioural genetics was founded as a scientific discipline by Francis Galton in the late 19th century, only to be discredited through association with eugenics movements before and during World War II. In the latter half of the 20th century, the field saw renewed prominence with research on inheritance of behaviour and mental illness in humans (typically using twin and family studies), as well as research on genetically informative model organisms through selective breeding and cros ...

Social Psychology
Social psychology is the methodical study of how thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. Although studying many of the same substantive topics as its counterpart in the field of sociology, psychological social psychology places more emphasis on the individual, rather than society; the influence of social structure and culture on individual outcomes, such as personality, behavior, and one's position in social hierarchies. 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. History 19th century In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial And Organizational Psychology
Industrial and organizational psychology (I-O psychology) "focuses the lens of psychological science on a key aspect of human life, namely, their work lives. In general, the goals of I-O psychology are to better understand and optimize the effectiveness, health, and well-being of both individuals and organizations." It is an applied discipline within psychology and is an international profession. I-O psychology is also known as occupational psychology in the United Kingdom, organisational psychology in Australia, South Africa and New Zealand, and work and organizational (WO) psychology throughout Europe and Brazil. Industrial, work, and organizational (IWO) psychology is the broader, more global term for the science and profession.Spector P. E. (2021). Industrial and Organizational Psychology: Research and Practice 8th ed. Hoboken, NJ: John Wiley. I-O psychologists are trained in the scientist–practitioner model. As an applied psychology field, the discipline involves both res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Educational Psychology
Educational psychology is the branch of psychology concerned with the scientific study of human learning. The study of learning processes, from both cognitive psychology, cognitive and behavioral psychology, behavioral perspectives, allows researchers to understand individual differences in intelligence, cognitive development, Affect (psychology), affect, motivation, self-regulation, and self-concept, as well as their role in learning. The field of educational psychology relies heavily on quantitative methods, including testing and measurement, to enhance educational activities related to instructional design, classroom management, and assessment, which serve to facilitate learning processes in various educational settings across the lifespan.Snowman, Jack (1997). Educational Psychology: What Do We Teach, What Should We Teach?. "Educational Psychology", 9, 151-169 Educational psychology can in part be understood through its relationship with other disciplines.
