During a period of crisis in which someone becomes depressed and suicidal, an association is learned between the various symptoms (low mood, physical pain, suicidal tendencies, and so on). This means that when the negative mood returns, for any reason, it will tend to trigger all the other symptoms – a process called “cognitive reactivity”).
在患者陷入抑郁、试图轻生的危机时刻，各种症状在患者的体内建立了联系（情绪低落、生理痛楚、自杀倾向等诸如此类）。这意味着一旦负面情绪由于某种原因再度出现，就可能引发其它的所有症状¾这个过程被称为“认知反应”）。
