Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. 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.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010.

Health Psychology
Health psychology is the study of psychological and behavioral processes in health, illness, and healthcare. The discipline is concerned with understanding how psychological, behavioral, and cultural factors contribute to physical health and illness. Psychological factors can affect health directly. For example, chronically occurring environmental stressors affecting the hypothalamic–pituitary–adrenal axis, cumulatively, can harm health. Behavioral factors can also affect a person's health. For example, certain behaviors can, over time, harm (smoking or consuming excessive amounts of alcohol) or enhance (engaging in exercise) health.Ogden, J. (2012). ''Health Psychology: A Textbook (5th ed.).'' Maidenhead, UK: Open University Press. Health psychologists take a biopsychosocial approach. In other words, health psychologists understand health to be the product not only of biological processes (e.g., a virus, tumor, etc.) but also of psychological (e.g., thoughts and beliefs), ...

Forensic Psychology
Forensic psychology is the development and application of scientific knowledge and methods to help answer legal questions arising in criminal, civil, contractual, or other judicial proceedings. Forensic psychology includes both research on various psychology-law topics, such as jury selection, reducing systemic racism in criminal law, and eyewitness testimony, as well as professional practice, such as evaluating individuals to determine competency to stand trial or assessing military veterans for service-connected disability compensation.

Sport psychology was defined by the European Federation of Sport in 1996, as the study of the psychological basis, processes, and effects of sport. Otherwise, sport is considered as any physical activity where the individuals engage for competition and health. Sport psychology is recognized as an interdisciplinary science that draws on knowledge from many related fields including biomechanics, physiology, kinesiology and psychology.

Counseling Psychology
Counseling psychology is a psychological specialty that encompasses research and applied work in several broad domains: counseling process and outcome; supervision and training; career development and counseling; and prevention and health. Some unifying themes among counseling psychologists include a focus on assets and strengths, person–environment interactions, educational and career development, brief interactions, and a focus on intact personalities. History The term "counselling" is of American origin, coined by Carl Rogers, who, lacking a medical qualification was prevented from calling his work psychotherapy. In the U.S., counselling psychology, like many modern psychology specialties, started as a result of World War II. During the war, the U.S. military had a strong need for vocational placement and training. In the 1940s and 1950s, the Veterans Administration created a specialty called "counseling psychology", and Division 17 (now known as the Society for Coun ...

In addition, positron emission tomography, PET scans and functional magnetic re ...

Community Psychology
Community psychology is concerned with the community as the unit of study. This contrasts with most psychology which focuses on the individual. Community psychology also studies the community as a context for the individuals within it,Jim Orford, ''Community Psychology: Challenges, Controversies and Emerging Consensus'', John Wiley and Sons, 2008 and the relationships of the individual to communities and society. Community psychologists seek to understand the functioning of the community, including the quality of life of persons within groups, organizations and institutions, communities, and society. Their aim is to enhance quality of life through collaborative research and action.Dalton, J.H., Elias, M.J., & Wandersman, A. (2001). "Community Psychology: Linking Individuals and Communities." Stamford, CT: Wadsworth. Community psychology employs various perspectives within and outside psychology to address issues of communities, the relationships within them, and related people's ...

Psychotherapy
Psychotherapy (also psychological therapy, talk therapy, or talking therapy) is the use of psychological methods, particularly when based on regular personal interaction, to help a person change behavior, increase happiness, and overcome problems. Psychotherapy aims to improve an individual's well-being and mental health, to resolve or mitigate troublesome behaviors, beliefs, compulsions, thoughts, or emotions, and to improve relationships and social skills. Numerous types of psychotherapy have been designed either for individual adults, families, or children and adolescents. Certain types of psychotherapy are considered evidence-based for treating some diagnosed mental disorders; other types have been criticized as pseudoscience. There are hundreds of psychotherapy techniques, some being minor variations; others are based on very different conceptions of psychology. Most involve one-to-one sessions, between the client and therapist, but some are conducted with groups, inc ...
