"Learning, memory, development, and evolution"

该提案的重点是建立和测试学习，记忆，发展和进化的计算模型，以更好地了解这些过程如何在人类中工作。对于学习和发展，我们使用受大脑工作原理启发的人工神经网络。这些模型有助于理解心理发展中的各种问题：为什么儿童会经历思维阶段，为什么儿童会犯错误，以及儿童认知发展障碍的原因和补救措施。好的模型实现了一个具体的，易于研究的现象版本，其中不重要的细节被剥离，以便更容易理解基本原理。在这个建议中，我们更具体地集中在模拟儿童对他人思想的想法的发展，特别是行为背后的信念和欲望。儿童在早期阶段会认为其他人与他们有着相同的信念。后来孩子们开始意识到其他人有时可能会怀有错误的信念。我们还提出了模型记忆检索如何把这些记忆在一个不稳定的状态，允许他们被重新巩固。在新的、相关的信息出现时，提取的记忆可以被改变。这对错误的目击者证词以及治疗创伤后压力都有影响。我们还将模拟婴儿在自己的学习中发挥积极作用的能力，例如，通过放弃对他们来说太难的任务来学习。这表明他们可能有能力监控自己的学习进度，并在缺乏进展时有意识地转向其他东西。最后，我们还模拟了不同种类的学习能力的生物进化，这些学习能力是在相互作用、解决问题、根据适应度繁殖并最终死亡的代理群体中进行的。我们感兴趣的是个体学习、模仿和关于世界的理论从一个主体传递到另一个主体之间的相互作用。我们的目标是发现这些不同的学习技术是如何通过自然选择创造的，以及它们如何反过来影响生物进化的过程。********

This proposal focuses on building and testing computational models of learning, memory, development, and evolution to better understand how these processes work in humans. For learning and development, we use artificial neural networks inspired by principles of how brains work. Such models contribute to understanding of a variety of issues in psychological development: why children go through stages in their thinking, why children make the mistakes that they do, and the causes and remedies for disorders in children's cognitive development. Good models implement a concrete, easy-to-study version of phenomena, in which unimportant details are stripped away so that the basic principles can be more easily understood. In this proposal, we concentrate more specifically on simulating the development of children's ideas about other people's minds, particularly the beliefs and desires that underlie behaviour. Children go through an early stage in which they assume that other people share the same beliefs as they themselves possess. Then later children come to appreciate that other people may sometimes harbour false beliefs. We also propose to model how memory retrieval puts those memories in an unstable state allowing them to be reconsolidated. In the presence of new, relevant information, retrieved memories can be changed. This has implications for faulty eyewitness testimony as well as treating post-traumatic stress. We will also simulate the ability of infants to take an active role in their own learning, e.g., by quitting tasks that are too difficult for them to learn. This suggests that they might have the ability to monitor their own progress in learning and the sense to move on to something else when there is lack of progress. Finally, we also simulate the biological evolution of different kinds of learning ability in populations of agents that interact, solve problems, reproduce according to their fitness, and eventually die. We are interested in the interplay between individual learning, imitation, and the passing of theories about the world from one agent to another. We aim to discover how these different learning techniques are created by natural selection and how they, in turn, affect the course of biological evolution. ********
