Spatial attentional biases can be observed during the processing of linguistic material. For example, we previously reported that healthy subjects overestimate the semantic distance between word stimuli in the right vs. left space. Here, we explored whether or not attentional biases are also observed in tasks requiring an evaluation of phonological distance between words in the right and left hemifield. Forty-one healthy subjects were presented with triplets of words arranged in space and were asked to indicate the side of the space in which the phonological distance between the middle word and an outer word was smaller. In Experiment 1, real words and pseudowords were used, while in Experiment 2, only pseudowords and consonant strings were used. Subjects overestimated the phonological distance between the middle and outer words in the right space. These findings were specific to word stimuli. These results are consistent with the idea that semantic and phonological information may be internally mapped onto spatial representations.
在语言材料处理过程中可以观察到空间注意偏向。例如，我们之前报道过，健康受试者高估了右侧与左侧空间中单词刺激之间的语义距离。在此，我们探究了在需要评估左右半视野中单词之间语音距离的任务中是否也能观察到注意偏向。向41名健康受试者呈现按空间排列的单词三元组，并要求他们指出中间单词与外部单词之间语音距离较小的空间一侧。在实验1中，使用了真词和假词，而在实验2中，仅使用了假词和辅音串。受试者高估了右侧空间中中间单词与外部单词之间的语音距离。这些发现特定于单词刺激。这些结果与语义和语音信息可能在内部映射到空间表征的观点一致。
