We investigated potential relationships between cannabis use and 2 phenomena associated with autobiographical remembering: the fading affect bias (FAB) and memory specificity. The FAB is an emotional affect regulation mechanism that is observed when the intensity of affect associated with experiencing negative memories fades faster than the intensity of affect associated with experiencing positive memories. Memory specificity refers to the level of detail with which events are recalled. No studies have examined the relationships between cannabis use, the FAB, and memory specificity simultaneously. Chronic cannabis users (N = 47) and non-users (N = 52) recalled and described positive and negative autobiographical events and rated the affective intensity for the events at the time of occurrence and at time of test. Participants retrieved additional memories using a sentence-completion recall task, which were coded for specificity. Cannabis users showed reduced fading affect for unpleasant events and reduced memory specificity compared to non-users.
情绪消退偏差（FAB）和记忆特异性。FAB 是一种情绪情感调节机制，当与体验消极记忆相关的情感强度比与体验积极记忆相关的情感强度消退得更快时，就会观察到这种机制。记忆特异性是指事件被回忆的详细程度。没有研究同时检查大麻使用、FAB 和记忆特异性之间的关系。慢性大麻使用者（N=47）和非使用者（N=52）回忆和描述了积极和消极的自传体事件，并在事件发生时和测试时对事件的情感强度进行了评级。参与者使用句子完成回忆任务检索其他记忆，这些记忆被编码为特异性。与非使用者相比，大麻使用者的不愉快事件情绪消退和记忆特异性降低。
