A trigger event is an occurrence that initiates a specific response or action within a system or process. In various fields, such as software development or psychology, triggers can lead to changes in behavior, status, or conditions. For example, in programming, a trigger might execute a function when a user submits a form. In the context of psychology, a trigger can refer to a stimulus that provokes an emotional reaction, often linked to past experiences. Understanding triggers is essential for managing responses and improving coping strategies, especially in therapeutic settings.
