Biologically plausible models of language-related behavior (such as learning to apply words correctly to perceived objects, judging concept similarity, or assessing sentiment) can be constructed without symbolic representations
Determining the emotional tone or feeling expressed in language—whether something is positive, negative, or neutral.
symbolic representations(Contrasted with imagistic representations in the context of language processing)
Mental representations that encode content through abstract symbols rather than sensory images; the form posited by representationalist and connectionist accounts of language content.
On the other hand, if the computational goal is to demonstrate human-like performance in a biologically plausible (or biologically valid!) model of some form of language-related behavior, such as learning to apply words correctly to perceived objects or relationships, or learning to judge concept similarity, or to assess the tone (underlying sentiment) of a discourse segment, then symbolic representations need not play any role in the computational modeling. (However, to the extent that language
