This experiment investigated the impact of suggestion focus on posthypnotic amnesia (PHA) for memories of a first romantic relationship. During hypnosis, high and low hypnotisable participants recalled specific memories from this period in response to 10 cue phrases (Elicitation). They then received a PHA suggestion that targeted either the entire period or specific memories from that period. Participants' explicit memory was indexed by cued recall after PHA was administered (memories recalled to "old" and "new" cues; Recall 1) and after it was cancelled (Recall 2). A social judgement task indexed dissociations between implicit and explicit memory. PHA had the greatest impact on highs', but not lows', memory performance (in terms of memories recalled to old cues, recall latency, and qualitative memory ratings) when the suggestion targeted the entire period rather than specific events. We discuss these findings in terms of the parameters of PHA's influence on memory, its value for exploring the nature and structure of autobiographical memory, and its utility as a laboratory analogue of functional amnesia.
本实验研究了暗示焦点对首次恋爱关系记忆的催眠后遗忘（PHA）的影响。在催眠过程中，高催眠易感性和低催眠易感性的参与者根据10个提示短语（唤起）回忆了这一时期的特定记忆。然后，他们接受了一个PHA暗示，该暗示要么针对整个时期，要么针对该时期的特定记忆。参与者的外显记忆通过在给予PHA后（回忆给“旧”和“新”提示；回忆1）和取消后（回忆2）的线索回忆来索引。一项社会判断任务索引了内隐记忆和外显记忆之间的分离。当暗示针对整个时期而非特定事件时，PHA对高催眠易感性参与者的记忆表现（根据回忆给旧提示的记忆、回忆潜伏期和记忆质量评分）影响最大，而对低催眠易感性参与者则没有影响。我们从PHA对记忆影响的参数、其在探索自传体记忆的性质和结构方面的价值以及其作为功能性失忆的实验室模拟的效用等方面讨论了这些发现。
