视觉对象知觉如何受到分散注意力的限制？然而，一些理论提出它根本不受限制（无限容量），另一些理论则提出，分散注意力引入了限制性容量限制或串行处理（固定容量）。我们使用一个任务来解决这个问题，在这个任务中，观察者搜索特定对象类别的实例，比如驼鹿或松鼠。我们采用扩展的同时-顺序范式来检验固定容量和无限容量模型（实验1）。结果与固定容量一致，拒绝无限容量。我们确定这些结果是由于注意力，而不是感官相互作用，如拥挤，通过重复实验，使用物理上相同的显示提示范式（实验2）。两个实验的结果都与固定容量的客体知觉理论一致，而否定了无限容量的客体知觉理论。具有固定容量的串联和并联模式仍然是可行的选择。
How is visual object perception limited by divided attention? Whereas some theories have proposed that it is not limited at all (unlimited capacity), others have proposed that divided attention introduces restrictive capacity limitations or serial processing (fixed capacity). We addressed this question using a task in which observers searched for instances of particular object categories, such as a moose or squirrel. We applied an extended simultaneous-sequential paradigm to test the fixed-capacity and unlimited-capacity models (Experiment 1). The results were consistent with fixed capacity and rejected unlimited capacity. We ascertained that these results were due to attention, and not to sensory interactions such as crowding, by repeating the experiment using a cuing paradigm with physically identical displays (Experiment 2). The results from both experiments were consistent with theories of object perception that have fixed capacity, and they rejected theories with unlimited capacity. Both serial and parallel models with fixed capacity remain viable alternatives.
