According to a standard view in psychology and neuroscience, there are multiple memory systems in the brain. Philosophers and scientists of memory rely on the idea that there are multiple memory systems in the brain to infer that procedural memory is not a cognitive form of memory. As a result, memory is considered to be a disunified capacity. In this article, I evaluate two criteria used by Michaelian to demarcate between cognitive and non-cognitive memory systems: appeal to stored content and retrieval flexibility. By considering several empirical cases I argue that the criteria offered ultimately fail to distinguish between memory systems. The procedural memory system is neither contentless nor inflexible.

记忆系统和程序记忆的记忆特征

根据心理学和神经科学的标准观点，大脑中有多个记忆系统。记忆哲学家和科学家依靠大脑中存在多个记忆系统的观点来推断程序性记忆不是记忆的认知形式。因此，记忆被认为是一种不统一的能力。在本文中，我评估了米迦勒用来区分认知和非认知记忆系统的两个标准：对存储内容的吸引力和检索灵活性。通过考虑几个经验案例，我认为所提供的标准最终无法区分记忆系统。程序性记忆系统既不是无内容的，也不是僵化的。
