We introduce a new agent-based model of opinion dynamics in which binary opinions of each agent can be measured and described regarding both pre- and post-influence at both of two levels, public and private, vis-à-vis the influence source. The model combines ideas introduced within the q-voter model with noise, proposed by physicists, with the descriptive, four-dimensional model of social response, formulated by social psychologists. We investigate two versions of the same model that differ only by the updating order: an opinion on the public level is updated before an opinion on the private level or vice versa. We show how the results on the macroscopic scale depend on this order. The main finding of this paper is that both models produce the same outcome if one looks only at such a macroscopic variable as the total number of the individuals with positive opinions. However, if also the level of internal harmony (viz., dissonance) is measured, then significant, qualitative differences are seen between these two versions of the model. All results were obtained simultaneously within Monte Carlo simulations and analytical calculations. We discuss the importance of our studies and findings from three points of view: the theory of phase transitions, agent-based modeling of social systems, and social psychology.
我们引入了一种新的基于主体的意见动态模型，其中每个主体的二元意见可以在两个层面上进行测量和描述，即公共层面和私人层面，同时考虑到与影响源的关系。该模型结合了物理学家提出的 q-投票者模型中的思想与噪声，以及社会心理学家提出的具有描述性的四维社会反应模型。我们研究了两种相同模型的版本，它们仅在更新顺序上有所不同：公共层面的意见先于私人层面的意见更新，或者反之。我们展示了在宏观尺度上，这种顺序如何影响结果。本文的主要发现是，如果只关注总数等宏观变量积极意见的个体，那么这两种模型会产生相同的结果。然而，如果还测量内部和谐程度（即不和谐程度），那么这两个版本的模型之间就会出现显著的定性差异。所有结果都是通过蒙特卡罗模拟和分析计算同时获得的。我们从三个角度讨论了我们的研究和发现的重要性：相变理论、社会系统的基于主体建模和社会心理学。
