The Hebb repetition effect (i.e., the enhanced recall performance for a sequence of items that is repeated during a serial recall experiment) is considered an experimental analogue to language learning. However, although language learning occurs in a context in which multiple verbal sequences are repeated concurrently, the effect of increasing the number of repeated sequences in the Hebb repetition paradigm has received little attention, and previous studies have used tasks that depart considerably from the natural language learning experience. In the present study, we manipulated the number of repeated sequences in a Hebb repetition paradigm that is a close experimental analogue of language learning. Participants were asked to orally recall sequences of 7 nonsense syllables that were aurally presented. The paradigm included 1 or 3 sequences that were repeated every 4th trial. The results showed that participants could learn 3 sequences simultaneously and they could do so as easily as they would learn a single sequence. The results provide additional evidence to models relating the Hebb repetition effect to word-form learning. (PsycINFO Database Record
赫布重复效应（即在系列回忆实验中重复呈现的一系列项目的回忆表现增强）被认为是语言学习的一种实验模拟。然而，尽管语言学习发生在多个言语序列同时重复的情境中，但在赫布重复范式中增加重复序列数量的影响却很少受到关注，并且先前的研究使用的任务与自然语言学习体验有很大差异。在本研究中，我们在一个与语言学习密切相关的实验模拟的赫布重复范式中操纵了重复序列的数量。参与者被要求口头回忆听觉呈现的7个无意义音节的序列。该范式包括每4次试验重复1个或3个序列。结果表明，参与者可以同时学习3个序列，并且他们学习3个序列的难易程度与学习单个序列一样。这些结果为将赫布重复效应与词形学习相关的模型提供了额外的证据。（PsycINFO数据库记录）
