 Proponents of the semantic conception differ as to how exactly they gloss the core claim that some computations are “sensitive” to semantic properties. They also differ in their stance towards CCTM. Block (1990) and Rescorla (2014a) focus upon CCTM. They argue that a symbol’s semantic properties can impact mechanical operations executed by a Turing-style computational system. In contrast, O’Brien and Opie (2006) favor connectionism over CCTM.
