心理语言信息在言语短时记忆中起着重要作用。一个这样的语言特征是邻域密度（ND）-通过改变单个音素或单个字母可以从给定单词中导出的单词数量-当单词序列来自密集而不是稀疏邻域时，vSTM性能通常更好。这种效应归因于密集的邻近词之间的支持激活水平较高。一般来说，它已被假设，词汇变量影响项目记忆，但顺序记忆，我们表明，典型的vSTM优势密集的邻域词在串行召回时，使用串行识别被淘汰。然而，我们也表明，ND的通常效果是相反的，无论是连续回忆和连续记忆，当使用这些相同的词的子集。研究结果提出了质疑的方式，ND已被纳入帐户的vSTM调用相互支持的长期表示编码或检索。
Psycholinguistic information plays an important role in verbal short-term memory (vSTM). One such linguistic feature is neighbourhood density (ND)-the number of words that can be derived from a given word by changing a single phoneme or single letter-with vSTM performance typically better when word sequences are from dense rather than sparse neighbourhoods. This effect has been attributed to higher levels of supportive activation among dense neighbourhood words. Generally, it has been assumed that lexical variables influence item memory but not order memory, and we show that the typical vSTM advantage for dense neighbourhood words in serial recall is eliminated when using serial recognition. However, we also show that the usual effect of ND is reversed-for both serial recall and serial recognition-when using a subset of those same words. The findings call into question the way in which ND has been incorporated into accounts of vSTM that invoke mutual support from long-term representations on either encoding or retrieval.
