Facilitatory priming effects due to similarity of orthographic form are obtained for high-N target words provided that they have low-frequency bodies and the body is shared between the prime and target (e.g., perd-HERD). Conversely, it is shown that low-N target words show priming regardless of the frequency of the body, provided that the prime and target do not share the same body (e.g., drice-DRIVE). If the body is shared, then priming occurs only for targets with low-frequency bodies. These results suggest that neighborhood density should be defined in terms of both individual letter units and subsyllabic units and that both types of density jointly determine priming.
对于高邻接密度的目标词，如果它们具有低频的词干部分且启动词和目标词共享该词干（例如，perd - HERD），那么由于正字法形式的相似性会产生促进性启动效应。相反，研究表明，低邻接密度的目标词无论词干频率如何都会表现出启动效应，只要启动词和目标词不共享相同的词干（例如，drice - DRIVE）。如果词干是共享的，那么启动效应仅出现在具有低频词干的目标词上。这些结果表明，邻接密度应根据单个字母单元和次音节单元来定义，并且这两种类型的密度共同决定启动效应。
