Fodor和Pylyshyn对联结主义的批判对联结主义者提出了挑战：在不假设一种“思想语言”（LOT）的情况下，准确地解释诸如系统性和生产力之类的法则性问题。一些联结主义者，如斯摩棱斯基，非常认真地对待这一挑战，并试图通过发展那些被认为是非经典的模型来迎接它。这些尝试的核心在于声称，连接主义模型可以提供一个表征系统与组合句法和句法结构敏感的过程。它们不是实现模型，因为它们获得语法和结构敏感性的方式不是“连接”的，因此与古典主义者处理它们的方式“根本不同”。在本文中，我提供了一个物理上满足/实现一个正式的系统是什么分析。在此背景下，我研究了LOT假设的最小真值条件。从我的分析可以得出，形式系统的连接实现与LOTH无关，因为LOT的概念与连接这样的实现级别问题无关。我的结论是，在某种程度上，它们能够解释类规律的认知活动，某些联结主义模型被提出来作为经典LOT范式的激进替代品，实际上将成为LOT模型，尽管是新的和潜在的非常令人兴奋的模型。
Fodor and Pylyshyn's critique of connectionism has posed a challenge to connectionists: Adequately explain such nomological regularities as systematicity and productivity without postulating a ''language of thought'' (LOT). Some connectionists like Smolensky took the challenge very seriously, and attempted to meet it by developing models that were supposed to be non-classical. At the core of these attempts lies the claim that connectionist models can provide a representational system with a combinatorial syntax and processes sensitive to syntactic structure. They are not implementation models because, it is claimed, the way they obtain syntax and structure sensitivity is not ''concatenative,'' hence ''radically different'' from the way classicists handle them. In this paper, I offer an analysis of what it is to physically satisfy/realize a formal system. In this context, I examine the minimal truth-conditions of LOT Hypothesis. From my analysis it will follow that concatenative realization of formal systems is irrelevant to LOTH since the very notion of LOT is indifferent to such an implementation level issue as concatenation. I will conclude that to the extent to which they can explain the law-like cognitive regularities, a certain class of connectionist models proposed as radical alternatives to the classical LOT paradigm will in fact turn out to be LOT models, even though new and potentially very exciting ones.
