What are examples of abnormal behavior in psychology?

Abnormal behavior in psychology can include a range of actions or thoughts that deviate significantly from societal norms, such as persistent fear or anxiety that interferes with daily life (e.g., phobias or generalized anxiety disorder), extreme mood swings indicative of Bipolar disorder, or compulsive behaviors seen in obsessive-compulsive disorder. Other examples include hallucinations or delusions associated with schizophrenia, and withdrawal from social interactions in conditions like depression. These behaviors often lead to significant distress or impairment in functioning and are typically assessed using established diagnostic criteria.
