My main purpose here is to provide an account of context selection in utterance understanding in terms of the role played by schemata and goals in top-down processing. The general idea is that information is organized hierarchically, with items iteratively organized in chunks—here called “schemata”—at multiple levels, so that the activation of any items spreads to schemata that are the most accessible due to previous experience. The activation of a schema, in turn, activates its other components, so as to predict a likely context for the original item. Since each input activates its own schemata, conflicting schemata compete with (and inhibit) each other, while multiple activations of a schema raise its likelihood to win the competition. There is therefore a double movement—with bottom-up activation of schemata enabling top-down prediction of other contextual components—triggered by multiple sources. Another claim of the paper is that goals are represented by schemata placed at the highest-levels of the executive hierarchy, in accordance with Fuster’s model of the brain as a hierarchically organized perception action cycle. This account can be considered, in part at least, a development of ideas contained in Relevance Theory, though it may imply that some other claims of the theory are in need of revision. Therefore, a secondary purpose of the paper is a contribution to the analysis of that theory.

In the philosophical and cognitive literature, the word ‘intention’ has been used with a variety of meanings which occasionally have been explicitly distinguished. I claim that an important cause of this polysemy is the fact that intentions are complex entities, endowed with an internal structure, and that sometimes different theories in the field are erroneously presented as if they were in conflict with each other, while they in fact just focus on different aspects of the phenomenon. The debate between Gallese’s embodied simulation theory and Csibra and Gergely’s teleological stance hypothesis is discussed as a case in point, and some misunderstandings occurring in that debate are analyzed. The thesis that intentions are complex entities is argued for by shedding light on the following aspects of intentions: conscious control; perceptual (and not only motoric) representations of end-states; attributions of value to those representations; appreciation of the rational relationships between means and ends.

According to Grice's “Modified Occam's Razor”, in case of uncertainty between the implicature account and the polysemy account of word uses it is parsimonious to opt for the former. However, it is widely agreed that uses can be partially conventionalised by repetition. This fact, I argue, raises a serious problem for MOR as a methodological principle, but also for the substantial notion of implicature in lexical pragmatics. In order to overcome these problems, I propose to reinterpret implicatures in terms of implicature-like effects delivered by non-inferential processes.
