生物运动知觉加工的朝向偏向特征

【摘要】：冠状面视角的生物运动知觉中存在一个特殊现象,正射投影的光点行走人物具有双稳态特性,即对于同一个刺激,既可被知觉为朝向观察者(facing-the-viewer),也可被知觉为背向观察者(facing-away),但人们知觉到朝向观察者的概率往往远高于背向观察者,这个现象被称为生物运动的朝向偏向(facingbias)。以往研究显示,自上而下和自下而上的因素可能对朝向偏向均存在一定的影响。但是,这些研究并未区分自下而上因素与自上而下因素的不同作用。另外,局部运动信息对生物运动朝向偏向这种特殊的高水平知觉过程是否也存在影响,也尚待探究。鉴于此,本研究一方面通过改变局部运动信息的时间关系和空间关系,探讨局部运动信息对朝向偏向的影响;另一方面通过对社交焦虑水平(自上而下因素)和局部运动信息(自下而上因素)的作用进行比较,揭示朝向偏向的加工特征。本研究的结果有利于进一步揭示生物运动知觉,尤其是朝向偏向知觉的加工规律。本研究总共包含3个实验:实验1考察局部运动空间关系信息对朝向偏向的影响;实验2考察局部运动时间关系信息对朝向偏向的影响;实验3则综合考察局部运动的时间和空间关系对朝向偏向的影响,同时比较社会焦虑水平和局部运动信息的不同作用。本研究获得以下结果:(1)与侧面视角的朝向知觉不同,冠状面视角的生物运动朝向知觉不受局部运动信息的影响,这与后者的双稳态特性和社会生物特性相关;(2)与局部运动信息对朝向偏向没有影响不同,社会焦虑水平对朝向偏向产生了显著的影响,即自上而下的因素在生物运动的朝向偏向加工中起主导作用,自下而上因素的重要程度相对较弱。总之,本研究认为,与其他生物运动的知觉过程不同,生物运动的朝向偏向主要基于对自上而下因素的加工而引发,自下而上因素的加工对其的作用较弱。
[Abstract]:There is a special phenomenon in the biological motion perception of the coronal angle of view, in which the walking figure with positive projection has a bistable characteristic, that is, for the same stimulus, It can be perceived as either a facing-the-viewer or a facing-away, but people tend to be far more likely to feel towards the observer than the back observer, a phenomenon known as the orientation bias (facingbias). Of biological movement Previous studies have shown that both top-down and bottom-up factors may have an effect on the orientation bias. However, these studies do not distinguish between bottom-up factors and top-down factors. In addition, whether the local movement information has influence on the special high level perception process of biological movement orientation is still to be explored. In view of this, on the one hand, by changing the temporal and spatial relationship of local motion information, the influence of local motion information on orientation bias is discussed. On the other hand, the effects of social anxiety level (top-down factor) and local movement information (bottom-up factor) were compared to reveal the processing characteristics of orientation bias. The results of this study are helpful to further reveal the processing law of biological motion perception, especially towards biased perception. This study consists of three experiments: experiment 1 examines the effect of local motion spatial relationship information on orientation bias, experiment 2 studies the effect of local motion time relation information on orientation bias; In experiment 3, the effects of temporal and spatial relationship of local movement on orientation bias were comprehensively investigated, and the different effects of social anxiety level and local motion information were compared at the same time. The results of this study are as follows: (1) different from the orientation perception of the lateral angle, the biological motion orientation perception of the coronal angle is not affected by the local motion information. This is related to the bistable and sociobiological characteristics of the latter. (2) the level of social anxiety has a significant effect on the orientation bias, and the local movement information has no effect on the orientation bias. That is, top-down factors play a leading role in the orientation bias processing of biological movement, and the importance of bottom-up factors is relatively weak. In conclusion, this study suggests that, unlike other biological movements, the orientation bias of biological movement is mainly caused by the processing of top-down factors, but the effect of bottom-up factors is weak.
