Too much could explain addictive or compulsive behavior, because it would help a user ignore other things and focus a lot of attention on one particular goal. 過量則可以解釋成癮或強迫行為，因為它將讓使用者忽略其他事物，對某一特定目標投入極大關注。
Patients often become introverted, exhibit compulsive behaviors and lose inhibitions that would otherwise prevent them from acting inappropriately toward others in social settings. 患者常會變得內向，表現出強迫行為，而且平常在社交場合中，防止自己對別人做出不當行為的抑制能力也喪失了。
