Basic science (psychology)

Last updated

Some of the research that is conducted in the field of psychology is more "fundamental" than the research conducted in the applied psychological disciplines, and does not necessarily have a direct application. The subdisciplines within psychology that can be thought to reflect a basic-science orientation include biological psychology, cognitive psychology, neuropsychology, and so on. Research in these subdisciplines is characterized by methodological rigor. The concern of psychology as a basic science is in understanding the laws and processes that underlie behavior, cognition, and emotion. Psychology as a basic science provides a foundation for applied psychology. Applied psychology, by contrast, involves the application of psychological principles and theories yielded up by the basic psychological sciences; these applications are aimed at overcoming problems or promoting well-being in areas such as mental and physical health and education.

Abnormal psychology

Abnormal psychology is the branch of psychology devoted to the study unusual patterns of behavior, emotion, and thought, including that which can be understood to represent mental disorder. Abnormal psychology is distinct from clinical psychology, an applied field of psychology that seeks to assess, understand, and treat psychological conditions that are harmful to the individual. However, the field of abnormal psychology provides a backdrop for clinical work. Psychopathology is a term used in abnormal psychology that suggests an underlying pathology.

Behavioral genetics

Behavioral genetics, also referred to as behavior genetics, is a field of scientific research that uses genetic methods to investigate the nature and origins of individual differences in behavior. Although the name "behavioral genetics" connotes a focus on genetic influences, the field broadly investigates the extent to which genetic and environmental factors influence individual differences, using research designs that allow removal of the confounding of genes and environment.

Biological psychology

Biological psychology or behavioral neuroscience is the scientific study of the biological bases of behavior and mental processes. Biological psychologists view all behavior as dependent on the nervous system, and study the neural basis for behavior. This is the approach taken in behavioral neuroscience, cognitive neuroscience, and neuropsychology. The goal of neuropsychology is to understand how the structure and function of the brain relate to specific behavioral and psychological processes. Neuropsychology is particularly concerned with brain injury in attempting to understand normal psychological function. Cognitive neuroscientists often use neuroimaging tools, which can help them to observe which areas of the brain are active during a particular task.

Cognitive psychology

Cognitive psychology involves the study of cognition, including mental processes underlying perception, learning, problem solving, reasoning, thinking, memory, attention, language, and emotion. Classical cognitive psychology has developed an information processing model of mental function, and has been informed by functionalism and experimental psychology.

Cognitive science is an interdisciplinary research enterprise that involves cognitive psychologists, cognitive neuroscientists, artificial intelligence, linguists, human–computer interaction, computational neuroscience, logicians and social scientists. Computational models are sometimes used to simulate phenomena of interest. Computational models provide a tool for studying the functional organization of the mind whereas neuroscience is more concerned with brain activity.

Developmental psychology

Developmental psychology is concerned with the development of the human mind and behavior over the life course. Developmental psychologists seek to understand how people come to perceive, understand, and act within the world and how these processes change as they age. They may focus on intellectual, cognitive, neural, social, or moral development. Developmental researchers who study children use a number of unique research methods, including observations in natural settings and the engaging of children directly in experimental tasks. Some experimental tasks resemble specially designed games and activities that are both enjoyable for the child and scientifically useful. Developmental psychologists have even devised methods to study the mental processes of infants. In addition to studying children, developmental psychologists also study the relation of aging to mental processes.

Experimental psychology

Experimental psychology represents a methodological approach to psychology rather than a content area subject. Experimental psychology lends itself to a variety of fields within psychology, including neuroscience, developmental psychology, sensation, perception, attention, learning, memory, thinking, and language. There is even an experimental social psychology. Experimental psychologists are researchers who employ experimental methods to help discover processes underlying behavior and cognition.

Evolutionary psychology

A goal of evolutionary psychology is to explain psychological traits and processes such as memory, perception, or language in terms of adaptations that arose in the evolutionary history of humans. Traits and processes are thought to be functional products of random mutations and natural selection. Evolutionary biologists view physiological mechanisms, such as the heart, lungs, and immune system, in similar terms. Evolutionary psychology applies the same thinking to psychology. Evolutionary psychologists advance the view that much of human behavior is the cumulative result of psychological adaptations that evolved to solve problems in human ancestral environments. For example, Steven Pinker hypothesized that humans have inherited special mental capacities for acquiring language, making language acquisition nearly automatic, while inheriting no capacity specifically for reading and writing.

Mathematical psychology

Mathematical psychology represents an approach to psychological research that is based on mathematical modeling of perceptual, cognitive, and motoric processes. Mathematical psychology contributes to the establishment of law-like rules that pertain to quantifiable stimulus characteristics and quantifiable behavior. Because the quantification of behavior is fundamental to mathematical psychology, measurement is a central topic in mathematical psychology. Mathematical psychology is closely related to psychometric theory. However, psychometricians are largely concerned with individual differences in mostly static, trait-like variables. By contrast, the focal concern of mathematical psychology is process models in such areas as perception and cognition. Mathematical psychology is intimately involved in the modeling of data obtained from experimental paradigms, making it closely related to experimental psychology and cognitive psychology.

Neuropsychology

Neuropsychology involves the study of the structure and function of the brain as it relates to specific psychological processes and overt behaviors. Neuropsychological research includes studies of humans and animals with brain lesions. Neuropsychologists have also studied electrical activity in individual brain cells (or groups of cells) in humans and other primates. Neuropsychology shares much with neuroscience, neurology, cognitive psychology, and cognitive science.

Personality psychology

A goal of personality psychology is to investigate enduring patterns of behavior, thought, and emotion in individuals. Personality psychologists are especially interested in individual differences. Within the framework of personality psychology, trait theorists attempt to analyze personality in terms of a limited number of key psychological traits. This type of research is highly dependent on statistical methods. The number of proposed traits has varied; however, there is some consensus over an empirically driven theory known as the "Big 5" personality model.

Psychophysics

Psychophysics is a discipline concerned with the relation between physical stimuli and their subjective correlates, or percepts or sensations. Psychophysics involves a set of methods that can be employed in research on perceptual systems. Modern applications of psychophysics rely heavily on ideal observer analyses and signal detection theory.

Social psychology

Social psychology involves the study of social behavior and mental processes that pertain to social behavior. Social psychology is concerned with how humans think about each other and how they relate to each other. Social psychologists study topics such as social influences on individual behavior (e.g. conformity and persuasion), belief formation, attitudes, and stereotypes. Social cognition integrates social and cognitive psychology in order to help discover how people process, remember, and distort social information. Research on group dynamics is pertinent to understanding the nature of leadership and communication.

<span class="mw-page-title-main">Cognitive science</span> Interdisciplinary scientific study of cognitive processes

Cognitive science is the interdisciplinary, scientific study of the mind and its processes with input from linguistics, psychology, neuroscience, philosophy, computer science/artificial intelligence, and anthropology. It examines the nature, the tasks, and the functions of cognition. Cognitive scientists study intelligence and behavior, with a focus on how nervous systems represent, process, and transform information. Mental faculties of concern to cognitive scientists include language, perception, memory, attention, reasoning, and emotion; to understand these faculties, cognitive scientists borrow from fields such as linguistics, psychology, artificial intelligence, philosophy, neuroscience, and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision to logic and planning; from neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."

Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning.

Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regards to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural and sexual selection or non-adaptive by-products of other adaptive traits.

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.

<span class="mw-page-title-main">Cognitive neuroscience</span> Scientific field

Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes. It addresses the questions of how cognitive activities are affected or controlled by neural circuits in the brain. Cognitive neuroscience is a branch of both neuroscience and psychology, overlapping with disciplines such as behavioral neuroscience, cognitive psychology, physiological psychology and affective neuroscience. Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from neurobiology, and computational modeling.

Psychology is an academic and applied discipline involving the scientific study of human mental functions and behavior. Occasionally, in addition or opposition to employing the scientific method, it also relies on symbolic interpretation and critical analysis, although these traditions have tended to be less pronounced than in other social sciences, such as sociology. Psychologists study phenomena such as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Some, especially depth psychologists, also study the unconscious mind.

Philosophy of psychology is concerned with the history and foundations of psychology. It deals with both epistemological and ontological issues and shares interests with other fields, including philosophy of mind and theoretical psychology. Philosophical and theoretical psychology are intimately tied and are therefore sometimes used interchangeably or used together. However, philosophy of psychology relies more on debates general to philosophy and on philosophical methods, whereas theoretical psychology draws on multiple areas.

<span class="mw-page-title-main">Neuropsychology</span> Study of the brain related to specific psychological processes and behaviors

Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology focus on how injuries or illnesses of the brain affect cognitive and behavioral functions.

Social cognition is a topic within psychology that focuses on how people process, store, and apply information about other people and social situations. It focuses on the role that cognitive processes play in social interactions.

Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior. The mathematical approach is used with the goal of deriving hypotheses that are more exact and thus yield stricter empirical validations. There are five major research areas in mathematical psychology: learning and memory, perception and psychophysics, choice and decision-making, language and thinking, and measurement and scaling.

Social neuroscience is an interdisciplinary field devoted to understanding the relationship between social experiences and biological systems. Humans are fundamentally a social species, rather than solitary. As such, Homo sapiens create emergent organizations beyond the individual—structures that range from dyads, families, and groups to cities, civilizations, and cultures. In this regard, studies indicate that various social influences, including life events, poverty, unemployment and loneliness can influence health related biomarkers. The term "social neuroscience" can be traced to a publication entitled "Social Neuroscience Bulletin" which was published quarterly between 1988 and 1994. The term was subsequently popularized in an article by John Cacioppo and Gary Berntson, published in the American Psychologist in 1992. Cacioppo and Berntson are considered as the legitimate fathers of social neuroscience. Still a young field, social neuroscience is closely related to personality neuroscience, affective neuroscience and cognitive neuroscience, focusing on how the brain mediates social interactions. The biological underpinnings of social cognition are investigated in social cognitive neuroscience.

Evolutionary educational psychology is the study of the relation between inherent folk knowledge and abilities and accompanying inferential and attributional biases as these influence academic learning in evolutionarily novel cultural contexts, such as schools and the industrial workplace. The fundamental premises and principles of this discipline are presented below.

Neurodevelopmental framework for learning, like all frameworks, is an organizing structure through which learners and learning can be understood. Intelligence theories and neuropsychology inform many of them. The framework described below is a neurodevelopmental framework for learning. The neurodevelopmental framework was developed by the All Kinds of Minds Institute in collaboration with Dr. Mel Levine and the University of North Carolina's Clinical Center for the Study of Development and Learning. It is similar to other neuropsychological frameworks, including Alexander Luria's cultural-historical psychology and psychological activity theory, but also draws from disciplines such as speech-language pathology, occupational therapy, and physical therapy. It also shares components with other frameworks, some of which are listed below. However, it does not include a general intelligence factor, since the framework is used to describe learners in terms of profiles of strengths and weaknesses, as opposed to using labels, diagnoses, or broad ability levels. This framework was also developed to link with academic skills, such as reading and writing. Implications for education are discussed below as well as the connections to and compatibilities with several major educational policy issues.

Psychology encompasses a vast domain, and includes many different approaches to the study of mental processes and behavior.
