説明

<jats:p>Abstract: We examined the effect of the stimulus type and semantic categorization of the unexpected stimulus on sustained Inattentional Blindness (<jats:styled-content style="fixed-case">IB</jats:styled-content>). Results showed that observers could establish attentional set based on a higher level of semantic categorization, which tuned one's attention to prioritizing semantic content over others. The unexpected stimulus, congruent with the attended objects in semantic categorization, was more likely to be noticed, whereas the incongruent semantic stimulus seemed to be unseen. Semantic category‐level attentional set played a crucial role in breaking through <jats:styled-content style="fixed-case">IB</jats:styled-content>. The semantically congruent <jats:styled-content style="fixed-case">C</jats:styled-content>hinese characters stimulus was detected and recognized more often than a semantically congruent picture stimulus, indicating that <jats:styled-content style="fixed-case">C</jats:styled-content>hinese characters had more power to attract attention to escape sustained <jats:styled-content style="fixed-case">IB</jats:styled-content> than pictures involved in visual processing. Presumably the finding of <jats:styled-content style="fixed-case">C</jats:styled-content>hinese characters breaking through <jats:styled-content style="fixed-case">IB</jats:styled-content> more easily might be due to the fact that <jats:styled-content style="fixed-case">C</jats:styled-content>hinese characters look more distinct from pictures, rather than <jats:styled-content style="fixed-case">C</jats:styled-content>hinese characters being processed more easily. Further research should be taken to test the semantic processing efficiency between pictures and <jats:styled-content style="fixed-case">C</jats:styled-content>hinese characters in sustained <jats:styled-content style="fixed-case">IB</jats:styled-content>.</jats:p>
