Research has suggested that the word recognition process is influenced by the integration of orthographic information across words. The precise nature of this integration process may vary, however, depending on whether words are in temporal or spatial proximity. Here we present a lexical decision experiment, designed to compare temporal and spatial integration processes more directly. Masked priming was used to reveal effects of temporal integration, while the flanker paradigm was used to reveal effects of spatial integration. Primes/flankers were high-frequency orthographic neighbors of the target (blue-blur) or unrelated control words (head-blur). We replicated prior observations of inhibition in trials where the neighbor was used as a masked prime, while facilitation was observed in trials where the neighbor was presented as flanker. We conclude that sub-lexical orthographic information is integrated both temporally and spatially, but that spatial information is used to segregate lexical representations activated by spatially distinct sources.
研究表明，单词识别过程会受到跨单词正字法信息整合的影响。然而，这种整合过程的确切性质可能会有所不同，这取决于单词在时间上还是空间上的接近程度。在此，我们呈现一项词汇判断实验，旨在更直接地比较时间和空间整合过程。使用掩蔽启动来揭示时间整合的效果，而侧翼范式则用于揭示空间整合的效果。启动词/侧翼词是目标词（blue-blur，蓝色-模糊）的高频正字法邻接词或无关的控制词（head-blur，头部-模糊）。我们重复了之前的观察结果，即在将邻接词用作掩蔽启动词的试验中出现抑制效应，而在将邻接词呈现为侧翼词的试验中观察到促进效应。我们得出结论，次词汇正字法信息在时间和空间上都会被整合，但空间信息用于分离由空间上不同来源激活的词汇表征。
