Inhibition of Return on Three-dimensional Slant Plane
作者 沈模卫李伟健水仁德乔歆新高在峰张光强
中文摘要
以随机点立体图为实验材料,采用三维空间线索-目标范式,将刺激呈现于同一视野位置以排除眼跳因素干扰,通过观察有意注意倾斜平面和无意注意倾斜平面与测试平面间的方向一致性和角度一致性对测试平面加工的影响,探讨了注意在不同倾斜平面间的转移是否产生返回抑制。结果表明:(1)以视差线索构造的三维视觉空间中,存在与注意有关的返回抑制效应;(2)无意注意加工能导致致返回抑制,注意引导平面比无意注意平面引起更大的抑制效应。本研究的结果支持Posner返回抑制是由注意转移所致的观点。
英文摘要
Inhibition of return (IOR) has been a major research focus in the field of attention since Posner and Cohen (1984) discovered this phenomenon. There are two main views on the generation of IOR. The first view is postulated by Posner and Cohen (1984), which claims that IOR is the withdrawal of attention from a location that leaves an inhibitory tag. The second view is that IOR has a close relation with oculomotor system (Rafal, et al, 1989), and that superior colliculus plays a very important role (Sapir & Soroker, 1999). Both views have obtained much support. However, all the previous research used the cue-target paradigm in the two dimension space, in which a cue was displayed first to indicate a peripheral location before the target appeared. In this paradigm, the cue world lead to attention shift as well as a saccade (or a saccade plan), so the previous research on IOR generation could not separate the attention factor from oculomotor factor effectively. To eliminate saccade’s contribution to IOR, we explored the generation of IOR by using random dot stereogram with slant information as material.Sixteen individuals participated in the study. Two experiments were conducted using a three dimension spatial cue-target paradigm. First, a random dot stereogram was displayed in the center of the screen as a cue, and the participants were asked to pay attention to the slant orientation of the plane. Then a target displayed in the center of screen with the same or different slant orientation as the cue, and the participants were required to respond to the target’s slant orientation. Thus, in this paradigm the participants did not need to make saccades or saccade planes to complete the task. We varied the consistency of orientation and angle between focused plane and tested plane in experiment 1 and 2. We also varied the consistency of orientation and angle between unattended plane and tested plane in experiment 2. ANOVAs were performed in both experiments.The data analyses showed that the response to the plane having the same orientation with the cuing focused plane was much slower than that with different orientation. The response to the plane having the same orientation with cuing unattended plane was much slower than that with no cuing plane at all. The results suggested that there was attention-related inhibition of return in three dimension space which was formed by disparity. Both the focused plane and the unattended plane led to IOR, but the former condition had a greater inhibition effect. The results support that inhibition of return id related to attention.
