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.
Insanity, madness, lunacy, and craziness are behaviors caused by certain abnormal mental or behavioral patterns. Insanity can manifest as violations of societal norms, including a person or persons becoming a danger to themselves or to other people. Conceptually, mental insanity also is associated with the biological phenomenon of contagion as in the case of copycat suicides. In contemporary usage, the term insanity is an informal, un-scientific term denoting "mental instability"; thus, the term insanity defense is the legal definition of mental instability. In medicine, the general term psychosis is used to include the presence of delusions and/or hallucinations in a patient; and psychiatric illness is "psychopathology", not mental insanity.
Applied psychology is the use of psychological methods and findings of scientific psychology to solve practical problems of human and animal behavior and experience. Educational and organizational psychology, business management, law, health, product design, ergonomics, behavioural psychology, psychology of motivation, psychoanalysis, neuropsychology, psychiatry and mental health are just a few of the areas that have been influenced by the application of psychological principles and scientific findings. Some of the areas of applied psychology include counseling psychology, industrial and organizational psychology, engineering psychology, occupational health psychology, legal psychology, school psychology, sports psychology, community psychology, neuropsychology, medical psychology and clinical psychology, evolutionary psychology, human factors, forensic psychology and traffic psychology. In addition, a number of specialized areas in the general area of psychology have applied branches. However, the lines between sub-branch specializations and major applied psychology categories are often mixed or in some cases blurred. For example, a human factors psychologist might use a cognitive psychology theory. This could be described as human factor psychology or as applied cognitive psychology. When applied psychology is used in the treatment of behavioral disorders there are many experimental approaches to try and treat an individual. This type of psychology can be found in many of the subbranches in other fields of psychology.
School psychology is a field that applies principles from educational psychology, developmental psychology, clinical psychology, community psychology, and behavior analysis to meet the learning and behavioral health needs of children and adolescents. It is an area of applied psychology practiced by a school psychologist. They often collaborate with educators, families, school leaders, community members, and other professionals to create safe and supportive school environments.
Forensic psychology is the practice of psychology applied to the law. Forensic psychology is the application of scientific knowledge and methods to help answer legal questions arising in criminal, civil, contractual, or other judicial proceedings. Forensic psychology includes research on various psychology-law topics, such as jury selection, reducing systemic racism in criminal law, eyewitness testimony, evaluating competency to stand trial, or assessing military veterans for service-connected disability compensation. The American Psychological Association's Specialty Guidelines for Forensic Psychologists reference several psychology subdisciplines, such as social, clinical, experimental, counseling, and neuropsychology.
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.
Clinical neuropsychology is a sub-field of cognitive science and psychology concerned with the applied science of brain-behaviour relationships. Clinical neuropsychologists use this knowledge in the assessment, diagnosis, treatment, and or rehabilitation of patients across the lifespan with neurological, medical, neurodevelopmental and psychiatric conditions, as well as other cognitive and learning disorders. The branch of neuropsychology associated with children and young people is pediatric neuropsychology.
Criminal psychology, also referred to as criminological psychology, is the study of the views, thoughts, intentions, actions and reactions of criminals and suspects. It is a subfield of criminology and applied psychology.
Stephen J. Ceci is an American psychologist at Cornell University. He studies the accuracy of children's courtroom testimony, and he is an expert in the development of intelligence and memory. He has been the recipient of numerous awards, including the prestigious Lifetime Contribution Awards from the American Psychological Association (APA) and the Association for Psychological Science (APS) as well as many divisional and smaller society awards.
Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. The ancestor of modern profiling, R. Ressler of the FBI, considered profiling as a process of identifying all the psychological characteristics of an individual, forming a general description of the personality, based on the analysis of the crimes committed by him or her.
Forensic psychotherapy is the application of psychological knowledge to the treatment of offender-patients who commit violent acts against themselves or others. This form of treatment allows for a therapist to potentially understand the offender and their mental state. It gives the individual providing treatment the opportunity to examine further whether the offender’s criminal behavior was a conscious act or not, what exactly their association with violent behavior is, and what possible motives could have driven them. The discipline of forensic psychotherapy is one that requires the involvement of individuals other than simply the therapist and patient. A therapist may collaborate with other professionals, such as physicians, social workers, nurses and other psychologists in order to best serve the offenders’ needs. Whether the treatment is successful or not relies on a multitude of things, but typically ensuring that a systemic approach is taken and that all involved in the treatment process are well informed and supportive has proven to be the most effective. In addition to group work forensic psychotherapy may also involve therapeutic communities, individual interaction with victims as well as offenders, and family work. In order for this specialized therapy to be as effective as possible, it demands the compliance of not only the patient and therapist, but of the rest of society as well. The main focus of forensic psychotherapy is not to condone the acts of the offender, but to obtain a psychodynamic understanding of the offender in order to attempt to provide them with an effective form of treatment to help them take responsibility for any crimes committed and to prevent the perpetration of crimes by the offender in the future. Guidelines have been set to ensure proficiency in the field of Forensic Psychology.

Eyewitness testimony is the account a bystander or victim gives in the courtroom, describing what that person observed that occurred during the specific incident under investigation. Ideally this recollection of events is detailed; however, this is not always the case. This recollection is used as evidence to show what happened from a witness' point of view. Memory recall has been considered a credible source in the past, but has recently come under attack as forensics can now support psychologists in their claim that memories and individual perceptions can be unreliable, manipulated, and biased. As a result of this, many countries, and states within the United States, are now attempting to make changes in how eyewitness testimony is presented in court. Eyewitness testimony is a specialized focus within cognitive psychology.
A clinical formulation, also known as case formulation and problem formulation, is a theoretically-based explanation or conceptualisation of the information obtained from a clinical assessment. It offers a hypothesis about the cause and nature of the presenting problems and is considered an adjunct or alternative approach to the more categorical approach of psychiatric diagnosis. In clinical practice, formulations are used to communicate a hypothesis and provide framework for developing the most suitable treatment approach. It is most commonly used by clinical psychologists and is deemed to be a core component of that profession. Mental health nurses, social workers, and some psychiatrists may also use formulations.
Jack A. Apsche was an American psychologist who has focused his work on adolescents with behavior problems. Apsche was also an author, artist, presenter, consultant and lecturer.
Psychology encompasses a vast domain, and includes many different approaches to the study of mental processes and behavior. Below are the major areas of inquiry that taken together constitute psychology. A comprehensive list of the sub-fields and areas within psychology can be found at the list of psychology topics and list of psychology disciplines.
A psychological injury is the psychological or psychiatric consequence of a traumatic event or physical injury. Such an injury might result from events such as abusive behavior, whistleblower retaliation, bullying, kidnapping, rape, motor vehicular collision or other negligent action. It may cause impairments, disorders, and disabilities perhaps as an exacerbation of a pre-existing condition.
