Definition: Antedating is a concept in psychology that refers to an individual's perception of events or actions occurring earlier than their actual occurrence. It is often used as a way to understand how individuals perceive and react to past events, especially those that are perceived as negative or unexpected. Antedating can be seen as a reflection of a person's tendency to overstate the importance of certain events or decisions in the past, leading them to view these events negatively or even blame themselves for previous mistakes.
