Abstract: In the present study, we wanted to investigate whether under different quality of object-based representation conditions, the high quality of object-based representation and the low quality of object-based representation, we could both find object-based attention effect, and what the role of the quality of object-based representation was in object-based attention effect. The results were as follows: There was a significant object-based attention effect under the high quality of semantic object-based representation condition, but more importantly, we did not find a significant object-based attention effect under the low quality of semantic object-based representation condition. These results indicated that the quality of object representation played an important role in the generation of the semantic object-based attention effect.

Key words: Object-based attention, semantic object, the quality of object representation

摘要： 已有研究表明，除自下而上因素外，自上而下因素也能够对客体知觉起到调节作用，从而影响注意的分配。本研究以不同词频（高频和低频）的汉语双字词为实验材料，采用双矩形线索范式变式考察不同语义客体表征质量对基于语义客体注意效应的影响。结果发现，在高语义客体表征质量的条件下出现了基于语义客体的注意效应，而在低语义客体表征质量的条件下并未出现基于语义客体的注意效应。该结果表明，语义客体表征质量的高低是影响基于语义客体注意效应的重要因素。
