Psychologically means considering how someone's thoughts and feelings affect their behavior or reactions.
When people talk about something being psychologically significant, they usually mean that it has an impact on how we think, feel, or act. For example, a psychologist might study the psychological effects of a traumatic event on a person's life. In everyday conversations, you might hear someone say that a particular situation is "psychologically challenging," meaning it requires mental effort and resilience to deal with it. People also talk about being psychologically prepared for something, which means they've thought through their feelings and reactions in advance.
