Stimulus quality and word frequency produce additive effects in lexical decision performance, whereas the semantic priming effect interacts with both stimulus quality and word frequency effects. This pattern places important constraints on models of visual word recognition. In Experiment 1, all three variables were investigated within a single speeded pronunciation study. The results indicated that the joint effects of stimulus quality and word frequency were dependent upon prime relatedness. In particular, an additive effect of stimulus quality and word frequency was found after related primes, and an interactive effect was found after unrelated primes. It was hypothesized that this pattern reflects an adaptive reliance on related prime information within the experimental context. In Experiment 2, related primes were eliminated from the list, and the interactive effects of stimulus quality and word frequency found following unrelated primes in Experiment 1 reverted to additive effects for the same unrelated prime conditions. The results are supportive of a flexible lexical processor that adapts to both local prime information and global list-wide context.
刺激质量和词频在词汇判断表现中产生累加效应，而语义启动效应则与刺激质量和词频效应相互作用。这种模式对视觉单词识别模型施加了重要限制。在实验1中，在一项单一的快速发音研究中对所有三个变量进行了调查。结果表明，刺激质量和词频的联合效应取决于启动词的相关性。具体而言，在相关启动词之后发现了刺激质量和词频的累加效应，而在不相关启动词之后发现了交互效应。据推测，这种模式反映了在实验情境中对相关启动词信息的适应性依赖。在实验2中，从列表中删除了相关启动词，并且在实验1中不相关启动词之后发现的刺激质量和词频的交互效应在相同的不相关启动词条件下恢复为累加效应。结果支持了一种灵活的词汇处理器，它既能适应局部启动词信息，也能适应全局列表范围的语境。
