Modelling Memory with Types: semantics and neural representation

I will argue that record types in TTR (a type theory with records) can be used to model mental states such as memory or belief. For example, a type modelling a belief or memory state is a type of the way the world would be if our beliefs or memories were true. A sentence like: Sam thinks that Kim left is true just in case the type which is the content of "Kim left" matches the type modelling Sam's belief/memory state.I will discuss some of the ...

The neuropragmatics of dialogue and discourse

In real life communication, language is usually used for more than the exchange of propositional content. Speakers and listeners want to get things done by their exchange of linguistic utterances. For this to be achieved, brain networks beyond those for recognizing and speaking words and establishing syntactic and thematic relations between them (who did what to whom) need to be recruited. The same holds for the alignment of speakers and listeners in conversational settings. In my presentation I will discuss some of our fMRI studies ...

Dialogue Context in Memory

Recent years have seen the emergence of theories that can be used to analyze a variety of phenomena characteristic of conversational interaction, including non-sentential utterances, manual gestures, collaborative utterances and laughter. In all these cases the content of the utterance gets much of its content from the context (eliminating the antecedent leaves the utterance highly vague). Much of the rapid progress attained by theories of semantics and pragmatics in recent decades has involved a dynamic strategy where meaning emerges from gradual accumulation of information ...

A neural model of sensorimotor experience, and of the representation, storage and communication of events

Many cognitive scientists have advanced ‘embodied’ models of human language, in which language is connected in some way to the sensorimotor (SM) mechanisms that engage with the world. I’ll introduce a particular version of this idea, that has relevance for models of how language interfaces with long-term memory and with the emotional system.The foundation for my model is Dana Ballard’s (1997) proposal that the SM processes through which an agent engages with the world are structured as deictic routines: well-defined sequences of relatively discrete atomic attentional, sensory or motor actions (called deictic operations). I propose that agents experience sentence-sized ‘events’ ...

Episodic memory and the importance of attribution processes to assess the retrieved memory contents

The Integrative Memory model describes the core mechanisms leading to recollection (i.e., to recall qualitative details about a past event) and familiarity (i.e., to identify some event as previously encountered) as specific computational operations applying to specific types of representation. Critically, the model distinguishes them from the subjective experiences of remembering and knowing that only emerge following additional attribution operations. I will present evidence supporting several principles from the Integrative Memory model, notably data indicating that one can report a highly vivid experience of ...

Universal Anaphora and Dialogue Phenomena

The objective of the <a href="http://www.universalanaphora.org" target="_blank">Universal Anaphora initiative is to facilitate progress in the empirical study of anaphora by covering not just identity anaphora, but all aspects of anaphoric interpretation from identity of sense anaphora to bridging to discourse deixis in all languages and covering not just written language, but spoken dialogue as well. In fact, the first shared task associated with the initiative, the CODI/CRAC 2021 Shared Task, will be focused on dialogue. However, many of the characteristics of current ...

Language within the mosaic of social cognition

In spite of high genetic overlap and broadly similar neural organization between humans and non-human primates, humans surpass all other species in their abilities to solve novel problems, in the sophistication of their social and emotional reasoning mechanisms, and in the richness and flexibility of their communication system. How exactly these cognitive capacities evolved in humans remains debated. I will discuss three brain networks that support high-level cognition and the relationship among them: (i) the domain-general Multiple Demand (MD) network that has been linked ...

Multimodality and Memory: Outlining Interface Topics in Multimodal Natural Language Processing

Multimodal dialogue, the use of speech and non-speech signals, is the basic form of interaction. As such, it is couched in the basic interaction mechanism of grounding and repair. This apparently straightforward view already has a couple of repercussions: firstly, non-speech gestures need representations that are subject to parallelism constraints for clarification requests known from verbal expressions. Secondly, co-activity between speaker and addressee on some channel is the rule virtually for the whole timecourse of interaction and ...
