The authors examined patterns of facilitation under forward-masked priming conditions across 3 list contexts (Experiments 1-3) that varied with respect to properties of filler trials -- (a) mixed (morphological, orthographic, semantic), (b) identity, and (c) semantic -- but held the relatedness proportion constant (75%). Facilitation for targets that were related morphologically to their prime occurred regardless of filler context, but facilitation for semantically related pairs occurred only in the context of identity and semantic fillers. Facilitation was absent for orthographically similar prime-target pairs in all 3 filler contexts when matching numbers of orthographically similar word-word and word-nonword prime-target pairs rendered orthographic similarity uninformative with respect to lexicality of the target. Enhanced semantic and morphological facilitation in the context of identity and semantic relative to mixed fillers support a semantically attuned, as contrasted with a purely form-based, account of early morphological processing.
作者研究了在正向掩蔽启动条件下，跨越3种词表情境（实验1 - 3）的促进模式，这些情境在填充试验的属性方面有所不同——（a）混合的（形态、正字法、语义），（b）相同的，以及（c）语义的——但保持相关比例恒定（75%）。无论填充情境如何，与启动词在形态上相关的目标词都会出现促进效应，但语义相关对的促进效应仅出现在相同和语义填充的情境中。当数量匹配的正字法相似的词 - 词和词 - 非词启动 - 目标对使得正字法相似性对于目标词的词汇性而言无信息价值时，在所有3种填充情境中，正字法相似的启动 - 目标对都不存在促进效应。与混合填充相比，在相同和语义填充情境中增强的语义和形态促进效应支持了一种语义协调的早期形态加工解释，与纯粹基于形式的解释形成对比。
