Framing effects concern the having of different attitudes towards logically or necessarily equivalent contents. Framing is of crucial importance for cognitive science, behavioral economics, decision theory, and the social sciences at large. We model a typical kind of framing, grounded in (i) the structural distinction between beliefs activated in working memory and beliefs left inactive in long term memory, and (ii) the topic- or subject matter-sensitivity of belief: a feature of propositional attitudes which is attracting growing research attention. We introduce a class of models featuring (i) and (ii) to represent, and reason about, agents whose belief states can be subject to framing effects. We axiomatize a logic which we prove to be sound and complete with respect to the class.

框架效应涉及对逻辑上或必然等同的内容具有不同的态度。框架对于认知科学、行为经济学、决策理论和整个社会科学至关重要。我们模拟了一种典型的框架，其基础是 (i) 在工作记忆中激活的信念与在长期记忆中不活跃的信念之间的结构区别，以及 (ii) 信念的主题或主题敏感性：命题的一个特征态度正在引起越来越多的研究关注。我们引入了一类具有 (i) 和 (ii) 特征的模型来表示和推理其信念状态可能受到框架效应影响的主体。我们公理化一个逻辑，我们证明它是关于类的合理和完整的。
