Past research indicates that short-term memory can be immune to the effects of proactive interference (PI). Past research also indicates that immunity to PI is found only in those circumstances where phonemic representations of to-be-remembered items are present and provide discriminative information. The first three experiments demonstrate the existence of a further boundary condition. PI is observed only if interfering and target items are subsumed by the same cue. This finding suggests that short-term recall, like long-term recall, is cue dependent. Cuing effects are further explored in two experiments that manipulate category dominance. The finding that category dominance effects parallel PI effects strongly suggests that retrieval cues play a critical role in short-term recall.
以往的研究表明,短期记忆可能不受前摄干扰(PI)的影响。以往的研究还表明,只有在待记忆项目的音素表征存在并提供辨别信息的情况下,才会出现对PI的免疫。前三个实验证明了另一个边界条件的存在。只有当干扰项和目标项被同一个线索包含时,才会观察到PI。这一发现表明,短期回忆与长期回忆一样,依赖于线索。在另外两个操纵类别优势的实验中,进一步探讨了线索效应。类别优势效应与PI效应相似的这一发现,有力地表明了检索线索在短期回忆中起着关键作用。
