In this paper it is shown a quantum-like cognitive model that predicts the slowdown of opinion change. The model proposed is a heuristic model that can reproduces some experimental results, but no assumptions about quantum descriptions of the physical brain are made. In quantum-like cognitive models the measurement postulate represents a decision. It is well known that the measurement postulate is not an essential ingredient of quantum theory, a dynamical account of measurements can also be given. Experimental results corroborate with the equivalence between both accounts. The quantum Zeno effect is an exemplary case. In this paper it is shown that, in a quantum-like cognitive model, the equivalence between the projective and dynamical accounts reveal that evaluations of intentions to act can slow down the opinion change. A thought experiment is proposed and simulations indicate that the predicted slowdown can be observed for a wide variety of parameter values.

在本文中，它显示了一个类似量子的认知模型，可以预测观点变化的放缓。提出的模型是一种启发式模型，可以重现一些实验结果，但是没有对物理大脑的量子描述做任何假设。在类量子认知模型中，测量假设表示一个决定。众所周知，测量假设不是量子理论的必要组成部分，还可以给出测量的动力学说明。实验结果与两个帐户之间的等效性相符。量子芝诺效应是示例性情况。本文表明，在类似量子的认知模型中，投射性和动态性描述之间的等价关系表明，对行动意图的评估可以减缓观点的改变。
