To act out (or be acting out) is an English phrasal verb that means to express hidden or repressed feelings through disruptive behavior, or to physically perform a story or role. Depending on the context, it is used in two primary ways:
- Behavioral & Psychological: To express emotional distress, frustration, or unstated needs through unacceptable, aggressive, or disruptive actions rather than words (e.g., “When children feel anxious, they often start acting out.”).
- Dramatic & Literal: To perform a story, scene, role, or mental image using physical actions and dialogue (e.g., “The kids loved acting out their favorite movie scenes.”).
In psychology, acting out specifically refers to a defense mechanism where a person performs actions to discharge unconscious emotional tension without fully understanding why they are doing it.
“Acting Up” vs. “Acting Out” in Children
Although both terms describe misbehavior, they convey very different emotional meanings:
- Acting Up refers to routine, situational misbehavior caused by temporary conditions like tiredness, hunger, boredom, or overstimulation. It carries no assumption that the child is emotionally troubled.
- Acting Out implies that the misbehavior is a symptom of deeper emotional distress, grief, anxiety, or unaddressed trauma that the child cannot express verbally.
