人工代理通过确定性机制表现出主观偏好行为，暗示情感意识可能源于信息处理。
Inferring Affective Consciousness in an Artificial Agent: A Case Study
- 基于内在需求与环境资源的不确定性，构建确定性人工代理
- 该代理能产生类似愉悦偏好行为，无需真实感受
- 为意识与自由意志的物理基础提供新思路，适合认知科学爱好者
许多科学家认为，表现出‘享乐偏好行为’的生物体具有感受能力，因为它们对无营养但能带来快感的物质（如可卡因、吗啡）产生偏好，这种行为难以用无意识本能解释。本文探讨一种简单的人工代理，其具备情感系统特征，能对内在需求与环境资源的不确定性产生‘感受性’认知。尽管该代理完全由确定性规则驱动，却仍能表现出享乐偏好行为——这是一种看似主观的信息处理形式。我们进一步分析了这种人工构造行为对理解意识物理基础及自由意志体验的启示。
原文摘要 · Abstract (English)
Creatures that display 'hedonic place preference behaviour' are thought by many scientists to experience feelings, on the assumption that their attraction to pleasure-producing substances which lack nutritional value (e.g. cocaine, morphine) cannot easily be attributed to unconscious instinctual behaviour. In this paper, we discuss how a simple artificial agent that instantiates attributes of an affective system engaging in felt uncertainty about its intrinsic needs in relation to environmental resources can similarly display hedonic place preference behaviour -- through an apparently subjective form of information processing -- while simultaneously being entirely deter-ministic. We outline some implications of this artificially engineered behaviour for our understanding of the physical basis of consciousness and the experience of free will.
