Dissociation is a research area within psychology that focuses on the psychological phenomenon of dissociation, which is a disconnection between a person's thoughts, emotions, memories, or sense of identity. Dissociation can range from mild experiences of spacing out or daydreaming to more severe experiences such as dissociative disorders, where a person may lose touch with reality, experience memory gaps, or feel disconnected from their own body. Research in dissociation often explores the causes, symptoms, and treatment options for individuals experiencing dissociative symptoms. It is a complex and multifaceted area of study that intersects with various fields such as clinical psychology, neuropsychology, and trauma research.
