The Global Precedence Effect (GPE) suggests that the processing of global properties of a visual stimulus precedes the processing of local properties. The generality of this theory was argued for four decades during different known Perceptual Field Variables. The effect size of various PFVs, regarding the findings during these four decades, were pooled in our recent meta-analysis study. Pursuing the study, in the present paper, we explore the effects of Congruency, Size, and Sparsity and their interaction on global advantage in two different experiments with different task paradigms; Matching judgment and Similarity judgment. Upon results of these experiments, Congruency and Size have significant effects and Sparsity has small effects. Also, the task paradigm and its interaction with other PFVs are shown significant effects in this study, which shows the prominence of the role of task paradigms in evaluating PFVs' effects on GPE. Also, we found that the effects of these parameters were not specific to the special condition that individuals were instructed to retinal stabilize. So, the experiments were more extendible to daily human behavior.

翻译：全局优先效应（GPE）表明，视觉刺激的整体属性加工先于局部属性加工。在过去四十年中，这一理论的普适性在不同的已知知觉场变量（PFV）下一直存在争议。我们最近的元分析研究汇总了这四十年间不同PFV对全局优先效应的影响大小。在此基础上，本文通过两项采用不同任务范式（匹配判断和相似性判断）的实验，进一步探究了一致性、大小和稀疏性及其交互作用对全局优势的影响。实验结果表明，一致性和大小具有显著影响，而稀疏性影响较小。此外，任务范式及其与其他PFV的交互作用在本研究中显示出显著效应，这表明任务范式在评估PFV对GPE影响中具有突出作用。同时，我们发现这些参数的影响并非局限于个体被指示进行视网膜稳定的特定条件，因此本实验更易于推广至日常人类行为。
