The behavior of "peak response-log intensity" functions generated by the "dark glasses model" is examined and is shown to describe previously observed light adapted behavior in cone photoreceptors. The models of Boynton and Whitten (1970) and Norman and Werblin (1974) are closely related to the dark glasses model--the Boynton-Whitten model being more specific and the Normann-Werblin model more general. For the models, a certain parameter relationship will produce systems which have optimal intensity discriminative capacities. When the data are fitted, this parameter relationship--unitary adaptive strength--seems to emerge. Possible evolutionary and psychophysical implications are discussed.
研究了由“墨镜模型”生成的“峰值响应-对数强度”函数的行为,并表明其描述了先前在视锥光感受器中观察到的明适应行为。博因顿和惠滕(1970年)以及诺曼和韦布林(1974年)的模型与墨镜模型密切相关——博因顿-惠滕模型更具体,诺曼-韦布林模型更通用。对于这些模型,特定的参数关系将产生具有最佳强度辨别能力的系统。当对数据进行拟合时,这种参数关系——单一适应强度——似乎会出现。讨论了可能的进化和心理物理学意义。
