The author suggests that there is a general relationship betweenstimulus τ and its effect E, the so-called effect equation E=B log(1+γ),where B is a conditional constant having the same dimension or naturewith that of the corresponding effect E. This new idea is more or less supported by neuro-physiologicalexperiments and is strengthened by considering the fact that. humansensory acceptor organs can respond to stimuli of enormous intensitydifference. It is quite interesting to note that many psychological laws indistinct fields can be unified into one psychological model given by theeffect equation. For instance, from this equation we may derive the lawof forgetting and the Hyman formula of choice reaction time in thefield of experimental psychology, and also various experimental laws inpsychophysics, such as Fechner's law, Weber's law, the Ferry-Porterlaw and the Granit-Harper equation etc. The law of forgetting is thus modified to extend its validity to thetime range 0≤t<1, rendering it more comprehensive. Fechner's law isalso modified, avoiding the appearance of negative sensation. Besides,the relation between effect E and sensation S is discussed. TheGranit-Harper equation viewed in this model has been rendered moreeasily understandable. During the derivation of the Ferry-Porter law the author discoveredan apparent principle with regard to the speed and accuracy of infor-mation porcessing in the brain. Direct tests of the unified model can be obtained by analyzingcertain previously published data. The sample given in this paper is aneuro-physiological experiment on king crabs. Another sample will bepresented in a separate paper where the relationship between reactiontime and stimulus intensity will be dealt with.

本文通过对某些神经生理学实验结果的分析,从人体感受器官能够经受信号强度的巨大变化出发,建立了反映刺激τ和效应E一般关系的效应方程E=Blog(1+τ)。式中系数B为与效应E同量纲或性质的条件恒量。 值得注意的是,效应方程把心理学领域中许多不相关的经验定律用统一的模型联系起来。例如,从效应方程出发,能够推出实验心理学中的遗忘定律、海曼公式,心理物理学中的费希纳定律、韦伯定律、费瑞—帕特定律和格拉涅-哈帕公式等。 此外,对遗忘定律进行了修正,使其能适用于0≤t<1的时间范围,从而变得较全面。对费希纳定律也作了类似的修正,避免了出现负的感觉,并从不同角度阐述了效应E与感觉S的某些性质。对格拉涅-哈帕公式则作了较前更为合理的解释。 在推导关于闪光融合频率的费瑞-帕特定律时,得出一条影响中枢神经处理信息的速度和精度的规律。 作为这一模型的直接验证,可以从前人所作的一些实验数据分析中得出。本文举的例子为鲎鱼单根神经的实验;在另文里将举出反应时间依赖于刺激强度的另一个实例。

Schemes intending to improve Weber's law have been often proposed

近百年来,针对韦伯定律的各种修正方案,虽经多次提出,但始终未能成功地揭示差别阈对标准刺激强度的普适规律,或称“差别阈定理”。 本文以刺激-效应的统一模型为基础,推导出的差别阈定理,能在较小误差范围内拟合简单的提重实验以至韦伯分数变动百倍以上的明度实验。 对结果的分析还表明:在10~(-3)-10~3毫朗这个日常生活的照明范围里,人眼感受性的调制,主要靠瞳孔变化完成;间视觉的主要分析器是棒体本身;并给出了这个视觉区间的刺激强度上限。

The present paper begins with constructing a mathematical model for cortex effect E caused by stimulus code along the afferent channel.The model E=Blog(1+kI),k=I ̄(-b)/a in terms of stimulus intensity I is based on neurophysiological experiments and the practicality of receptor functions acquired in the long run of evolution.Accordingly, the criterion of difference limen for moderate stimuli has been shown to be △E=constant, which, being generaized to weak stimuli,leads to a resonable extension of Weber's law:△I/(I+aI ̄b)=constant...

The present paper begins with constructing a mathematical model for cortex effect E caused by stimulus code along the afferent channel.The model E=Blog(1+kI),k=I ̄(-b)/a in terms of stimulus intensity I is based on neurophysiological experiments and the practicality of receptor functions acquired in the long run of evolution.Accordingly, the criterion of difference limen for moderate stimuli has been shown to be △E=constant, which, being generaized to weak stimuli,leads to a resonable extension of Weber's law:△I/(I+aI ̄b)=constant N,which is valid to weak and strong stimuli. Thus the old problem over a hundred years ago concerning extend of the validity of Weber’s law to include weak stimuli seems to be more or less settled.

本文以神经生理学为基础,结合感官具有调节和比较两功能的实用性,建立起刺激在大脑皮层上引起感知效应E的数学模型:E=Blog(1+kI),其中k=I ̄(-b)/a。从此出发,可推出中等以上刺激的差别阈判据:△EM=恒量。将此判据推广到弱刺激,即得到差别阈的普适规律:△I/(I+aI ̄b)=N,亦即韦伯定律的修订公式。从弱到强的广大刺激范围内,它都能与实验数据拟合良好。
