【摘要】：近年来,视觉注意分配研究的重心逐渐从原来的人工合成刺激转变为真实世界的自然场景。场景主旨是一种特殊的刺激,它包含了场景刺激中一些粗糙的必要水平信息,依据这种信息我们能够高效的完成诸如场景分类等任务。然而对于这种高效的认知活动是否需要注意资源的参与却有着很大的分歧。依据注意资源特异性加工理论,本研究在两个实验中使用了双任务范式对真实场景分类任务的注意发生阶段问题进行了探究。在实验一中通过比较两种不同视觉属性任务与场景分类任务在双任务下的干扰情况,验证了不同视觉属性信息并不会造成的注意竞争。而在实验二中,为了进一步确定注意干扰发生在视觉加工阶段之后的猜想,我们使用了听觉任务对注意类型问题进行了进一步探究,结果发现,在听觉刺激条件下场景分类任务依旧会在双任务条件下产生注意竞争现象。据此,本研究提出了真实场景分类的注意消耗效应并不是发生在编码阶段的猜想,先前研究结果所得出的场景主旨需要消耗注意资源的结论是发生在中央注意阶段之上,从全新的角度解释了以往注意研究结果的分歧。
[Abstract]:In recent years, the focus of visual attention distribution has gradually changed from artificial stimulus to real world natural scene. The theme of the scene is a special stimulus, which contains some rough necessary level information in the scene stimulus, according to which we can efficiently accomplish tasks such as scene classification. However, there are great differences as to whether the efficient cognitive activities need to pay attention to the participation of resources. Based on the theory of attention resource specific processing, this study uses the two-task paradigm to explore the phase of attention generation of real-world scene classification tasks in two experiments. In the first experiment, by comparing the interference between two kinds of visual attribute tasks and scene classification tasks in two tasks, we verify that different visual attribute information does not cause attention competition. In experiment 2, in order to further confirm the conjecture that attention interference occurred after the visual processing stage, we used auditory task to further explore the problem of attention type, and found that, Scene classification tasks under auditory stimuli still produce attentional competition under dual-task conditions. Based on this, the present study proposes that the effect of attention consumption in real scene classification does not occur in the coding stage. The conclusion that the main purpose of the scene needs to consume attention resources is that it occurs above the central attention stage. This paper explains the differences of previous attention research results from a new perspective.
