Combining the Projective Consciousness Model and Virtual Humans to assess ToM capacity in Virtual Reality: a proof-of-concept
AI总结：
本文提出了一种结合投影意识模型与虚拟人评估ToM能力的方法，通过虚拟现实实验验证了该方法在模拟行为和评估心理参数方面的有效性。
摘要：
将显性的心理机制与可观察的行为联系起来是心理学和行为科学的核心目标。我们将投影意识模型的原则引入了以虚拟人形式体现的人工代理体，作为一种方法论框架的证明概念，旨在模拟行为并评估底层的心理参数，特别是在虚拟现实实验的背景下。我们专注于模拟理论 of mind（ToM）在选择接近和回避策略行为中的作用，以优化代理体偏好满足的程度。我们设计了一个可以在真实人类中使用的虚拟环境实验，允许我们根据ToM的顺序将行为分类，最高到第二顺序。我们显示，在此实验中，我们的代理体表现出预期的行为，并且具有一致的ToM参数。我们还显示，这些代理体可以正确地估计彼此的ToM顺序。类似的方法也可以用于虚拟现实实验中的真实人类，不仅使人类参与者能够与参数化的虚拟人作为刺激互动，还可以作为推断的手段，推导出基于模型的心理评估。
英文摘要：
Relating explicit psychological mechanisms and observable behaviours is a central aim of psychological and behavioural science. We implemented the principles of the Projective Consciousness Model into artificial agents embodied as virtual humans, as a proof-of-concept for a methodological framework aimed at simulating behaviours and assessing underlying psychological parameters, in the context of experiments in virtual reality. We focus on simulating the role of Theory of Mind (ToM) in the choice of strategic behaviours of approach and avoidance to optimise the satisfaction of agents' preferences. We designed an experiment in a virtual environment that could be used with real humans, allowing us to classify behaviours as a function of order of ToM, up to the second order. We show that our agents demonstrate expected behaviours with consistent parameters of ToM in this experiment. We also show that the agents can be used to estimate correctly each other order of ToM. A similar approach could be used with real humans in virtual reality experiments not only to enable human participants to interact with parametric, virtual humans as stimuli, but also as a mean of inference to derive model-based psychological assessments of the participants.
