Verified step by step guidance

1. Understand the concept of abnormal behavior in psychology, which refers to patterns of emotion, thought, or action considered pathological (dysfunctional or maladaptive) according to cultural norms.
2. Recognize that abnormal behavior is not always a sign of mental illness; some behaviors may be unusual but not indicative of a disorder.
3. Note that abnormal behavior does not necessarily involve criminal activity; legality and abnormality are distinct concepts.
4. Consider that abnormal behavior can sometimes be distressing to the individual, but this is not always the case; some individuals may not perceive their behavior as distressing.
5. Conclude that abnormal behavior is largely defined by cultural norms and can vary across societies, meaning what is considered abnormal in one culture may be normal in another.
