【摘要】：时间知觉是认知心理学的一个前沿领域,大量研究表明视觉通道中的时间知觉与客体的空间位置编码间存在紧密联系。而同时监控和加工发生在不同空间位置的多个时间事件是人类的一项基本能力。很多研究(BuhusiMeek,2009; Klapproth,2011; Matell, King,Meek,2004; MeekChurch,1984; MeekWilliams,1997; Olton, Wenk, Church,Meek,1988)证明了人类和动物都具有同时性时间加工机制,机体内部对于时间的累计并不是只有单一的一个时钟,而是存在多个独立的时钟分别进行计时。然而迄今为止,对于发生在视觉领域的同时性时间加工的容量机制研究甚少。本研究中使用了一个新的实验范式——奇异时段觉察范式(Temporal Oddball-Detection Paradigm, TODP),该范式结合了奇异时段觉察任务和广泛测量视觉工作记忆容量的变化觉察范式(Change-Detection Paradigm)的优点,对基于空间位置编码的同时性时间加工的容量(the capacity of STP (CSTP))机制进行了最初的系列实验研究。所得到的结论有(1)证实了基于空间位置编码的同时性时间加工的容量为3~4个空间位置,即人们能够对同时发生在3~4个空间位置的时间事件进行有效的监控。当时间估计基于视觉领域的多个空间位置的编码时,有3~4个内部时钟同时进行加工。(2)局部的时钟和其特定位置的结合受到了自下而上的空间注意竞争的影响,随着空间注意的分散而逐渐受到了削弱,表明时间和空间的捆绑是要消耗注意资源的。(3)同时性时间加工的容量并不受到视觉工作记忆容量的影响和制约,进而可以认为STP的存储和操作单元不同于VWM。
[Abstract]:Time perception is a frontier field in cognitive psychology. A large number of studies have shown that time perception in visual channels is closely related to the spatial position coding of objects, while monitoring and processing multiple time events occurring in different spatial locations at the same time is a basic human ability. The multiple studies Buhusi Meeki 2009; Klapprothia 2011; Matell, Kingsberg 2004; Meek Church1984; Meek Williamsl1997; Olton, Churk, Churchn Meeki 1988) prove that both humans and animals have simultaneous time-processing mechanisms, The accumulation of time within the body is not a single clock, but the existence of a number of separate clocks to time separately. There is little research on the capacity mechanism of simultaneous time processing in the field of vision. In this study, a new experimental paradigm, the singular Oddball-Detection Paradigm, is used, which combines the singular time perception task and the singular time perception task. The advantages of widely measuring the change perception paradigm of visual working memory capacity, such as Change-Detection Paradigm, A series of experimental studies on the capacity of the capacity of STP processing based on spatial position coding are carried out in this paper. The conclusions are as follows: 1) the capacity of simultaneous processing based on spatial position coding is confirmed. 3 ~ 4 space positions, When time estimation is based on the coding of multiple spatial positions in the field of vision, Three to four internal clocks are processed simultaneously.) the combination of local clocks and their specific positions is influenced by bottom-up spatial attention competition, and gradually weakened with the dispersion of spatial attention. It shows that the binding of time and space is to consume the attention resource. 3) the capacity of simultaneous processing is not affected and restricted by the capacity of visual working memory, so we can conclude that the storage and operation unit of STP is different from VWM.
