一些视觉选择性注意模型忽视了物体表征间的关联关系的存在。在此，我们认为这种关联关系特别影响人们注意的分布。 本研究包括两个实验：视觉搜索—言语报告任务中不同类型搜索项目的启动作用；视觉搜索—新近刺激判断任务中不同类型项目的竞争。 本研究得出如下结论： (1)不同年龄的被试在各类型视觉搜索、再认任务中的正确率和反应时以及自由回忆的正确率均表现出相同的趋势。视觉搜索的正确率和自由回忆以及再认的正确率随年龄的增长而提高，视觉搜索、再认的反应时则随年龄的提高而降低。 (2)关联项目作为搜索项目出现，对视觉搜索、再认的正确率和反应时以及自由回忆的正确率有显著影响，关联项目的出现使得视觉搜索和自由回忆以及再认的正确率降低，视觉搜索和再认的反应时提高。 (3)实验二与实验一相比，视觉搜索正确率提高，反应时降低。同时，再认正确率比自由回忆正确率提高。关联项目能够影响视觉选择性注意的特殊作用表现得更为明显。
Some visual selective attention models ignore the existence of associative links among object representations. Here we show that such associations can strongly influence deployment of attention in humans.The present research included two experiments: visual search and free recall task; visual search and recognition tasks.The study"s results showed that:(1)There is common trend with age in visual search and recognition tasks" accurate rate and reaction time, and free recall task"s accurate rate. Accurate rate of visual search, free recall, and recognition task increased with age, otherwise, reaction time of visual search and recognition decreased with age.(2)Taking the associated object as searching object will significantly affect both visual search and recognition tasks" accurate rate and reaction time, and only significantly affect free recall task"s accurate rate. The existence of associated object made the accurate rate of visual search, free recall, and recognition decreased, meanwhile made the reaction time of visual search and recognition increased.(3)Comparing experiment 1 with experiment 2, the latter visual search task"s accurate rate increased and reaction time decreased, meanwhile, accurate rate of the recognition task was higher than the free recall task. The special effect of associated object"s affecting visual selective attention is clearer in experiment 2.
