displacement

In psychology, displacement refers to the redirection of an emotion or impulse from its original object to another. This often occurs when an individual is experiencing conflicting drives, such as fear and aggression. Instead of expressing the emotion directly, it is redirected towards a less threatening target.12

Displacement can also manifest as a substitution of behavior, where an unusual or socially inappropriate response replaces a typical one. This might involve performing an act that is inappropriate for the situation, such as grooming or eating when feeling anxious or conflicted. Displacement is considered a defense mechanism, a mental process that helps individuals cope with internal conflicts and reduce anxiety.123
