回顾T. Caraco等人的发现（见记录1981-05141-001），即动物的觅食偏好对食物奖励概率分布的变化很敏感。T. Caraco（1980）提出，风险敏感性的某些方面可以通过最小化饥饿概率来解释。本文形式化了这一备选最优假设，并分析地证明了它解释了风险敏感性的存在及其某些方面的性质。（4 ref）（PsycINFO Database Record (c) 2017 APA，版权所有）
Reviews the findings of T. Caraco et al (see record 1981-05141-001) that the foraging preferences of animals are sensitive to variance in the proability distribution of a food reward. Also examined was T. Caraco's (1980) suggestion that some aspects of risk sensitivity may be explained by minimization of the probability of starvation. The present author formalizes this alternative optimality hypothesis and shows analytically that it accounts for the existence and some aspects of the nature of risk sensitivity.(4 ref)(PsycINFO Database Record (c) 2017 APA, all rights reserved)
