My current and planned research is aimed at deepening understanding of emotional cognition by developing new models of goal revision, emotional change, and a kind of irrationality I call "gut overreaction". I plan to develop neural network models of the development and revision of goals, greatly expanding my previous accounts of their contributions to decision making. The first objective for understanding goal revision is to explain how goals such as get a grant might be represented by a pattern of firing in a population of neurons. The second objective is to explain how people come to adopt new goals. The third objective is to explain how people sometimes come to abandon goals. My fourth objective is to explain how people increase or decrease the estimated importance of goals to a problem or decision. The theory of goal revision will be part of a larger theory of emotional change. The first objective in modeling emotional change will be to develop an account of all the ways in which appraisals can be modified. The second objective is to model ways in which physiological changes can influence emotional change that occur through external perception of stimuli such as scary images and through interventions such as drugs, relaxation exercises, and meditation practices. The third objective is to put the cognitive appraisal and physiological perception together in the integrated fashion proposed by the previously developed EMOCON model. The fourth objective is to identify mechanisms for long-term emotional change. The fifth objective is to apply an improved understanding of emotional change to processes of conflict resolution. One kind of emotional change produces a pattern of irrationality that can lead both to excessively positive assessments and to excessively negative ones. Such overreactions occur in many spheres of human life, with undesirable effects on financial decisions, personal relationships, and medical behavior. In order to understand the influence of gut overreactions on inference, I plan to develop computer simulations of the effects of amplifying feedback loops on inferential dynamics.

我目前和计划中的研究旨在通过开发目标修正、情绪变化和一种我称之为“直觉过度反应”的非理性的新模型来加深对情绪认知的理解。 我计划开发神经网络模型的发展和修订的目标，大大扩展了我以前的帐户的贡献，决策。 理解目标修正的第一个目标是解释诸如获得资助这样的目标是如何用神经元群体中的放电模式来表示的。第二个目的是解释人们是如何接受新目标的。第三个目的是解释人们有时是如何放弃目标的。 我的第四个目标是解释人们如何增加或减少目标对问题或决策的估计重要性。 目标修正理论将成为更大的情绪变化理论的一部分。 建立情绪变化模型的第一个目标是建立一个可以修改评价的所有方式的账户。 第二个目标是模拟生理变化影响情绪变化的方式，这些情绪变化是通过对刺激（如可怕的图像）的外部感知以及药物、放松练习和冥想练习等干预措施发生的。 第三个目标是把认知评价和生理感知在一起的综合方式提出了以前开发的EMOCON模型。第四个目标是确定长期情绪变化的机制。第五个目标是将对情绪变化的更好理解应用于解决冲突的过程。 一种情绪变化会产生一种非理性模式，既会导致过度积极的评价，也会导致过度消极的评价。 这种过度反应发生在人类生活的许多领域，对财务决策，个人关系和医疗行为产生不良影响。为了了解肠道过度反应对推理的影响，我计划开发计算机模拟放大反馈回路对推理动力学的影响。
