The indexical component (this liquid, our rivers) is crucial to reference determination: it wouldn't do to identify the referent of 'water' by way of some description ("liquid, transparent, quenches thirst, boils at 100°C, etc")., for something might fit the description yet fail to be water, as in Putnam's famous Twin Earth thought experiment (see the entry on reference).
Let it be noted that in Putnam's original proposal, reference determination is utterly independent of speakers' cognition: 'water' on Twin Earth refers to XYZ (not to H2O) even though the difference between the two substances is cognitively inert, so that before chemistry was created nobody on either Earth or Twin Earth could have told them apart.
And they use the 2D framework to represent a broadly internalist approach to reference determination.
The algorithm for current reference determination was adapted and implemented on DSP controller.
In this paper the current reference determination based on predictive filtering structure is presented.
Much of its appeal comes from the way it offers unified treatments of concept acquisition, categorization, and reference determination.
And reference determination, we've already seen, is a matter of whether the definitional constituents do apply to the target.
But just because the mechanisms of reference determination permit considerable psychological variability doesn't mean that there aren't, in fact, significant patterns for psychologists to uncover.
We've seen that conceptual structure is invoked to explain, among other things, typicality effects, reflective categorization, cognitive development, reference determination, and compositionality.
Beyond that, it is not easy for externalists to provide a satisfactory account of lexical semantic competence, as they are committed to regarding speakers' beliefs and abilities (e.g., recognitional abilities) as essentially irrelevant to reference determination, hence to meaning.
