The paper is devoted to the relationship between psychophysics and physics of mind. The basic trends in psychophysics development are briefly discussed with special attention focused on Teghtsoonian's hypotheses. These hypotheses pose the concept of the universality of inner psychophysics and enable us to speak about psychological space as an individual object with its own properties. Turning to the two-component description of human behavior I. Lubashevsky (2017) [9] the notion of mental space is formulated and human perception of external stimuli is treated as the emergence of the corresponding images in the mental space. On one hand, these images are caused by external stimuli and their magnitude bears the information about the intensity of the corresponding stimuli. On the other hand, the individual structure of such images as well as their persistence after emergence is determined only by the properties of mental space on its own. Finally, the mental operations of image comparison and their scaling are defined in a way allowing for the bounded capacity of human cognition. As demonstrated, the developed theory of stimulus perception is able to explain the basic regularities of psychophysics, e.g., (i) the regression and range effects leading to the overestimation of weak stimuli and the underestimation of strong stimuli, (ii) scalar variability (Weber's and Ekman' laws), and (iii) the sequential (memory) effects. As the final result, a solution to the Fechner-Stevens dilemma is proposed. This solution posits that Fechner's logarithmic law is not a consequences of Weber's law but stems from the interplay of uncertainty in evaluating stimulus intensities and the multi-step scaling required to overcome the stimulus incommensurability.

心理物理定律反映了心理空间特性。

本文致力于心理物理学与心理物理学之间的关系。简要讨论了心理物理学发展的基本趋势，并特别关注了德格修尼的假设。这些假设构成了内部心理物理学的普遍性概念，使我们能够将心理空间作为具有自身属性的单个对象进行论述。转向人类行为的两部分描述I. Lubashevsky（2017）[9]提出了心理空间的概念，人类对外部刺激的感知被视为心理空间中相应图像的出现。一方面，这些图像是由外部刺激引起的，其大小带有有关相应刺激强度的信息。另一方面，这些图像的个体结构以及它们出现后的持久性仅取决于心理空间本身的属性。最后，以允许人类认知能力有限的方式定义图像比较的心理操作及其缩放。如所证明的那样，发达的刺激感知理论能够解释心理物理学的基本规律，例如，（i）导致过度估计弱刺激和低估强烈刺激的回归和范围效应，（ii）标量变异性（韦伯和埃克曼定律），以及（iii）顺序（记忆）效应。作为最终结果，提出了解决Fechner-Stevens难题的方法。该解决方案假定费希纳的对数定律不是韦伯定律的结果。
