Psycology

Modern Psychology

Modern psychology is divided into several subdisciplines, each based on differing models of behavior and mental processes. Psychologists work in a number of different settings, including universities and colleges, primary and secondary schools, government agencies, private industry, hospitals, clinics, and private practices. Recent years have seen a rise in the significance of applied psychology—as can be seen from the areas contemporary psychologists concern themselves with—with an attendant decline in the importance of psychology in academia. In the United States, clinical psychology has become a significant focus of the discipline, largely separate from psychological research. Clinical psychologists are responsible for the diagnosis and treatment of various psychological problems.
Biological models of behavior have become increasingly prominent in psychological theory, particularly with the development of various tools—such as the positron emission tomography (PET) scan—for mapping the brain. The field of neuropsychology, which studies the brain and the connected nervous system, has been an outgrowth of this contemporary focus on biological explanations of human thought and behavior. Cognitive models, derived from the Gestalt school of psychology, focus on the various thinking processes which mediate between stimuli and responses.
Educational psychology, derived from the 18th and 19th cent. educational reforms of Friedrich W. Froebel, Johann Pestalozzi, and their follower Johann Herbart, was later expanded by G. Stanley Hall and by E. L. Thorndike. It is concerned with the development of improved methods of teaching and learning.
Social psychology, developed by British psychologists William McDougall and Havelock Ellis, studies the effects of various social environments on the individual. Some other branches of the field include developmental psychology, which studies the changes in thought and behavior through the course of life; experimental psychology, which is the laboratory research involved in the understanding of the mind; and personality psychology, which deals specifically with individual personality and the processes by which it is formed.
In recent years a number of new fields of psychology have emerged. Industrial/organizational psychology, emerging from social psychology, focuses on the workplace and considers such topics as job satisfaction, leadership, and productivity. Health psychology examines how psychological factors contribute to pathology, and demonstrates how psychology can contribute to recovery and illness prevention for such somatic disorders as heart disease, cancer, and diabetes. In environmental psychology, research focuses on how individuals react to their physical environments, and suggests improvements which may be beneficial to psychological health. Other new areas of psychology include counseling psychology, school psychology, forensic psychology, and community psychology.

psychology

 [sahy-kol-uh-jee] Show IPA
psychology,  science or study of the thought processes and behavior of humans and other animals in their interaction with the environment. Psychologists study processes of sense perception, thinking, learning, cognition, emotions and motivations, personality, abnormal behavior, interactions between individuals, and interactions with the environment. The field is closely allied with such disciplines as anthropology and sociology in its concerns with social and environmental influences on behavior; physics in its treatment of vision, hearing, and touch; and biology in the study of the physiological basis of behavior. In its earliest speculative period, psychological study was chiefly embodied in philosophical and theological discussions of the soul.

Development of Modern Psychology

The De anima  of Aristotle is considered the first monument of psychology as such, centered around the belief that the heart was the basis for mental activity. The foundations of modern psychology were laid by 17th-century philosopher Thomas Hobbes, who argued that scientific causes could be established for every sort of phenomenon through deductive reasoning. The mind-body theories of Rene Descartes, Baruch Spinoza, and G. W. Leibniz were equally crucial in the development of modern psychology, where the human mind's relation to the body and its actions have been significant topics of debate.
In England the empirical method employed in modern psychological study originated in the work of John Locke, George Berkeley, Thomas Reid, and David Hume. David Hartley, James Mill, John Stuart Mill, and Alexander Bain stressed the relation of physiology to psychology, an important development in the scientific techniques of modern psychology. Important contributions were made in the physiological understanding of human psychology by French philosopher Condillac, F. J. Gall, the German founder of phrenology, and French surgeon Paul Broca, who localized speech centers in the brain.
In the 19th cent., the laboratory work of Ernst Heinrich Weber, Gustave Fechner, Wilhelm Wundt, Hermann von Helmholtz, and Edward Titchener helped to establish psychology as a scientific discipline—both through the use of the scientific method of research, and in the belief that mental processes could be quantified with careful research techniques. The principle of evolution, stemming from Charles Darwin's theory of natural selection, gave rise to what became known as dynamic psychology. The new approach, presented by American psychologist William James in his Principles of Psychology  (1890), looked at consciousness as an evolutionary process.
Out of the new orientation in psychology grew the clinical experiments in hysteria and hypnotism carried on by J. M. Charcot and Pierre Janet in France. Sigmund Freud, in his influential theory of the unconscious, gave a new direction to psychology and laid the groundwork for the psychoanalytic model. Freudian theory took psychology into such fields as education, anthropology, and medicine, and Freudian research methods became the foundations of clinical psychology.
The behaviorism of American psychologist John B. Watson was highly influential in the 1920s and 30s, with its suggestion that psychology should concern itself solely with sensory stimuli and behavioral reaction. Behaviorism has been important in modern psychology, particularly through the work of B. F. Skinner since the 1930s.
Equally important was the development of Gestalt psychology by German psychologists Kurt Koffka, Wolfgang Köhler, and Max Wertheimer. Gestalt theory contended that the task of psychology was to study human thought and behavior as a whole, rather than breaking it down into isolated instances of stimulus and response.
Another influential school of psychology was developed in the 1950s and 60s by Abraham Maslow and Carl Rogers. Their humanistic theory asserts that people make rational, conscious decisions regarding their lives, and optimistically suggests that individuals tend to reach toward their greatest potential.

Psychology Schools of Thought and History

While people have always been fascinated by human behavior, it wasn’t until the late 19th century that psychology began to be considered an actual science. Wilhelm Wundt established the first psychology lab in Germany. He believed in an area of psychology called structuralism—believing that certain structures in the mind caused behavior. Over the course of psychology’s history, different schools of thought have competed for prominence. Here are the major psychology schools of thought:

•Structuralism. This area in pyschology holds the belief that there is a connection between sensation and emotion and behavior.

•Functionalism. This area in psychology suggests the idea that the human brain is much like a computer, designed to carry out specific functions.

•Psychoanalysis. This psychology school of thought was created by Sigmund Freud, and believes in the rigorous probing of an individual's personal problems, motives, goals and attitudes as a way to heal the mind.

•Behaviorism. Proponents of this area of psychology essentially hold that all human behavior is learned from one's surrounding context and environment.

•Humanism. This much more recent psychology school of thought came as a reaction to behaviorism and Psychoanalysis, and emphasizes the importance of values, intentions, and meaning in the individual. The concept of the "self" is a central focus for most humanistic psychologists.

•Cognitivism. This area in psychology believes that psychology should be concerned with a person's internal representations of the world and with the internal or functional organization of the mind.

As psychology moved away from its philosophical roots, psychologists began to employ more and more scientific methods to study human behavior; this opened up many more psychology careers. Today, researchers employ a variety of scientific methods, including experiments, correlational studies, longitudinal studies, and others to test, explain, and predict behavior.
Areas of Psychology

Students of psychology soon realize that the subject covers a huge range of material, and may never provide a definitive answer to the question, "What is psychology?" The diverse topics students might study as they explore the various areas in psychology include social behavior, personality, research methods, therapeutic techniques, and much more. Because it’s such a broad and diverse field, a number of different subfields and specialty areas have emerged. The following are some of the major areas of research and application within psychology, and provide some of the many rewarding and satisfying psychology careers:

•Abnormal Psychology is the study of abnormal behavior. This specialty area of psychology is focused on research and treatment of a variety of mental disorders and is linked to psychotherapy and clinical psychology.

•Biological Psychology studies how biological processes influence the mind and behavior. This area of psychology is closely linked to neuroscience and utilizes tools such as MRI and PET scans to look at brain injury or brain abnormalities.

•Clinical Psychology is focused on the assessment, diagnosis, and treatment of mental disorders.

•Cognitive Psychology is the study of human thought processes and cognitions. Cognitive psychologists study topics such as attention, memory, perception, decision-making, problem solving, and language acquisition.

•Comparative Psychology is the branch of psychology concerned with the study of animal behavior.

•Developmental Psychology is the area of psychology that looks at human growth and development over the lifespan.

•Forensic Psychology is an applied field focused on using psychological research and principles in the legal and criminal justice system.

•Industrial-Organizational Psychology is the area of psychology that uses psychological research to enhance work performance, select employee, improve product design, and enhance usability.

•Personality Psychology looks at the various elements that make up individual personalities.

•School Psychology is the area of psychology that works within the educational system to help children with emotional, social, and academic issues.

•Social Psychology is a psychology school of thought that uses scientific methods to study social influence, social perception, and social interaction. Social psychology studies diverse subjects including group behavior, social perception, leadership, nonverbal behavior, conformity, aggression, and prejudice.

Today, psychologists prefer to use more objective scientific methods to understand, explain, and predict human behavior. Psychological studies are highly structured, beginning with a hypothesis that is then empirically tested. Academic psychologists focus on the study of different sub-topics within psychology including personality psychology, social psychology, and developmental psychology. These psychologists conduct basic research that seeks to expand our theoretical knowledge, while other researchers conduct applied research that seeks to solve everyday problems. Applied psychology focuses on the use of different psychological principles to solve real world problems. Examples of applied areas of psychology include forensic psychology, ergonomics, and industrial-organizational psychology. Many other psychologists work as therapists, helping people overcome mental, behavioral, and emotional disorders.

Psychology is a broad and diverse field with a variety of related professions. If you are considering a career in psychology, you are pursuing one of the most important and basic of the human sciences. You can expect to have a long, satisfying, and fascinating career if psychology is your field.
