调查如何掩蔽不同的起源在9个实验与天真和有经验的大学生（N= 36）。刺激掩蔽的目标形式，只有单光学（或双眼），或单光学和dichoptically。外周前向掩蔽和后向掩蔽通过目标刺激能量与允许逃避掩蔽的目标偏移和掩蔽起始之间的最小间隔之间的简单关系来描述：最小间隔乘以目标能量等于常数。外周前掩蔽，但是，更敏感的掩模强度比外周后掩蔽。中央掩蔽，这主要是向后的，是相对不受刺激能量和2个刺激的发作之间的间隔流逝。乘法和发作发作规则的特点，分别是周边和中央视觉过程。外围过程被看作是一组并行的系统或网络信号的原始特征的刺激和中央过程作为一系列的决定进行，部分地，在这些功能，并导致刺激识别。它的结论是，周边和中央的过程是相关的并发和偶然的方式，显然是并行发生的，与中央的决定取决于输出的周边系统的信号以不同的速率不同的功能。（参考文献4页）（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Investigated how masking varies with origin in 9 experiments with naive and experienced undergraduates (N= 36). Stimuli masked the target forms only monoptically (or binocularly), or both monoptically and dichoptically. Peripheral forward and backward masking were described by a simple relation between target stimulus energy and the minimal interval between target offset and mask onset permitting evasion of masking: The minimal interval multiplied by the target energy equaled a constant. Peripheral forward masking, however, was more sensitive to mask intensity than was peripheral backward masking. Central masking, which was primarily backward, was relatively unaffected by stimulus energy and was determined by the interval elapsing between the onsets of the 2 stimuli. The multiplicative and the onset-onset rules characterized, respectively, peripheral and central visual processes. The peripheral processes are viewed as a set of parallel systems or nets signaling crude features of the stimulus and the central processes as a series of decisions conducted, in part, on these features and resulting in stimulus recognition. It is concluded that the peripheral and central processes are related in a concurrent and contingent fashion, apparently occurring in parallel, with the central decisions contingent on the output of the peripheral systems which signal different features at different rates.(4 p. ref.)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
