Virtual reality headsetA virtual reality headset (or VR headset) is a head-mounted device that provides virtual reality for the wearer. VR headsets are widely used with VR video games but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display (providing separate images for each eye), stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world.
HypnosisHypnosis is a human condition involving focused attention (the selective attention/selective inattention hypothesis, SASI), reduced peripheral awareness, and an enhanced capacity to respond to suggestion. There are competing theories explaining hypnosis and related phenomena. Altered state theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary state of consciousness.
Immersion (virtual reality)Immersion into virtual reality (VR) is a perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment. The name is a metaphoric use of the experience of submersion applied to representation, fiction or simulation.
Anti-psychiatryAnti-psychiatry, sometimes spelled antipsychiatry, is a movement based on the view that psychiatric treatment is often more damaging than helpful to patients, highlighting controversies about psychiatry. Objections include the reliability of psychiatric diagnosis, the questionable effectiveness and harm associated with psychiatric medications, the failure of psychiatry to demonstrate any disease treatment mechanism for psychiatric medication effects, and legal concerns about equal human rights and civil freedom being nullified by the presence of diagnosis.
HypnotherapyHypnotherapy is a type of mind–body intervention in which hypnosis is used to create a state of focused attention and increased suggestibility in the treatment of a medical or psychological disorder or concern. The United States Department of Labor's Dictionary of Occupational Titles (DOT) describes the job of the hypnotherapist:"Induces hypnotic state in client to increase motivation or alter behavior patterns: Consults with client to determine nature of problem.
EyeEyes are organs of the visual system. They provide living organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons (neurones).
Prolonged exposure therapyProlonged exposure therapy (PE) is a form of behavior therapy and cognitive behavioral therapy designed to treat post-traumatic stress disorder. It is characterized by two main treatment procedures – imaginal and in vivo exposures. Imaginal exposure is repeated 'on-purpose' retelling of the trauma memory. In vivo exposure is gradually confronting situations, places, and things that are reminders of the trauma or feel dangerous (despite being objectively safe). Additional procedures include processing of the trauma memory and breathing retraining.
Human eyeThe human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm. The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis.
Virtual reality sicknessVirtual reality sickness, or VR sickness occurs when exposure to a virtual environment causes symptoms that are similar to motion sickness symptoms. The most common symptoms are general discomfort, eye strain, headache, stomach awareness, nausea, vomiting, pallor, sweating, fatigue, drowsiness, disorientation, and apathy. Other symptoms include postural instability and retching. Common causes are low frame rate, input lag, and the vergence-accommodation-conflict.
Child and adolescent psychiatryChild and adolescent psychiatry (or pediatric psychiatry) is a branch of psychiatry that focuses on the diagnosis, treatment, and prevention of mental disorders in children, adolescents, and their families. It investigates the biopsychosocial factors that influence the development and course of psychiatric disorders and treatment responses to various interventions. Child and adolescent psychiatrists primarily use psychotherapy and/or medication to treat mental disorders in the pediatric population.
