In the present paper I analyse the modularity thesis and, more specifically, the thesis of domain-specificity of processing. I argue that this thesis is not trivial only under the assumption of a variety of processes which differ from each other at the implementation level; otherwise, the variety of cognitive processes can only be explained as emergent on the basic mechanism of associative activation in that it operates on domain-specific representations, which is something that no one would deny. But that assumption (...) is untenable: there are no other processes than associative activation (and inhibition) at the implementation level. Any claim to the contrary is the result of a conceptual confusion between two senses of “associative”: a behavioural one, relative to which there are cognitive processes that exceed the ability to code elementary spatio-temporal contingencies, and one that lies instead at the implementation level. Since the assumption of a plurality of processes at the implementation level is untenable, the only viable interpretation of modularism (as far as domain-specificity is concerned) is a trivial one. By this I do not mean that the thesis is devoid of any content. However, its content is scarcely debatable, and far less thrilling than the debate has suggested so far. (shrink)

Relevance Theory (RT) argues that human language comprehension processes tend to maximize “relevance,” and postulates that there is a relevance-based procedure that a hearer follows when trying to understand an utterance. Despite being highly influential, RT has been criticized for its failure to explain how speaker-related information, either the speaker’s abilities or her/his preferences, is incorporated into the hearer’s inferential, pragmatic process. An alternative proposal is that speaker-related information gains prominence due to representation of the speaker within higher level goal-directed (...) schemata. Yet the goal-based account is still unable to explain clearly how cross-domain information, for example linguistic meaning and speaker-related knowledge, is integrated within a modular system. On the basis of RT’s cognitive requirements, together with contemporary cognitive theory, we argue that this integration is realized by utilizing working memory and that there exist conversational constraints with which the constructed utterance interpretation should be consistent. We illustrate our arguments with a computational implementation of the proposed processes within a general cognitive architecture.Abbreviations: ACT-R Adaptive Control of Thought - RationalCOGENT Cognitive Objects within a Graphical ENvironmenTCS/SS Contention Scheduling/Supervisory SystemRBCP Relevance-Based Comprehension ProcedureRT Relevance Theory.

The paper investigates the epistemological and communicative competences the experts need to use and communicate evidence in the reasoning process leading to diagnosis. The diagnosis and diagnosis communication are presented as intertwined processes that should be jointly addressed in medical consultations, to empower patients’ compliance in illness management. The paper presents defeasible reasoning as specific to the diagnostic praxis, showing how this type of reasoning threatens effective diagnosis communication and entails that we should understand diagnostic evidence as defeasible as well. (...) It argues that metaphors might be effective communicative devices to let the patients understand the relevant defeasors in the diagnostic reasoning process, helping to improve effective diagnosis communication, and also encouraging a change in patients’ beliefs and attitudes on their own experience of illness and illness’ management.
