How prosody helps infants and children to break into communication

The talk will present four sets of studies with young infants and children to show who prosody helps them learn about different aspects of language, from learning basic word order through understanding focus to decoding emotional valence. The sets of studies are losely connected, but common to them is how prosody, an overaching feature of language, already encountered prenatally in the womb and manifesting in newborns' communicative cries, helps infants break into language and guides them through different developmental steps from grammar to communication.

How Do Pre- and Post-Encoding Processes Affect Episodic Memory?

What post-encoding processes cause forgetting? For decades there had been controversy as to whether forgetting is caused by decay over time or by interference from irrelevant information, and a coherent account for forgetting was lacking. My colleagues and I have proposed the Representation Theory of Forgetting, according to which forgetting can occur either due to decay or due to interference, depending on the nature of the memory-representation and the brain-structure supporting it. The hippocampus—a structure playing a crucial role in recollection—has a unique neurobiological ...

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 ...
