Answer :
Final answer:
The normal-abnormal continuity theory posits a spectrum of behavior with no clear line between normal and abnormal, emphasizing distress and dysfunction as defining factors.
Explanation:
Normal-abnormal continuity theory is the psychological perspective that suggests there is no clear dividing line between normal and abnormal behavior. This theory emphasizes that behaviors and experiences exist on a continuum, ranging from more accepted and typical to more deviant and abnormal.
Psychological disorders are diagnosed based on clinical observations that behaviors operate on a spectrum, with no distinct separation between normal and abnormal. For example, behaviors like hand washing can be a normal healthy activity but can become excessive in conditions like obsessive-compulsive disorder (OCD).
According to this perspective, the distinction between normal and abnormal behavior is not rigid but depends on the level of distress, dysfunction, and impairment caused to the individual in social or occupational activities.
