Title: Dynamic events in mind and language
Abstract:
Humans are surprisingly adept at interpreting what is happening around them and organizing this information in terms of dynamic events. Furthermore, across human communities, language is used to describe the events that we experience. But what, exactly, is an event? In this talk, I propose a theory of eventhood that combines insights from logico-philosophical analysis, cognitive psychology and linguistic theory. On this theory, the representational units of events in cognition rely on abstract underlying structure, including temporal boundaries. In that sense, events are similar to objects (since objects also involve abstract structure, including spatial boundaries). This proposal predicts systematic patterns in the way people spontaneously perceive unfolding events. It also explains otherwise mysterious similarities in how events and objects behave as cognitive entities. Finally, this proposal naturally accounts for the existence of a homology between the cognitive and linguistic structure of events. This framework opens up exciting possibilities for future research on how people represent, remember and talk about what happens.

Title: Linguistic and neural consequences of iconicity in American Sign Language
Abstract:
Iconicity (a resemblance between form and meaning) in sign languages appears to be much more pervasive and structured compared to spoken languages. Currently, however, we know very little about how iconicity might impact the structure of the lexicon or whether iconic signs are processed differently in the brain. My colleagues and I have been exploring the nature of the distribution of iconic forms in the American Sign Language (ASL) lexicon, what drives the iconic depiction of semantic features, and whether iconic signs are perceived and processed differently than non-iconic signs. We have used Event-Related Potentials (ERPs) to examine whether iconic signs exhibit a distinct “neural signature” for deaf fluent signers or for hearing new learners and whether effects of iconicity are task-dependent. Thus far, this work indicates a) iconic signs have a unique lexical distribution that differs from that of iconic spoken words, b) salient/distinctive semantic features are more likely to be iconically depicted in signs, c) there appears to be no neural signature that tracks with the strength of iconicity during sign recognition for fluent signers, d) the effects of sign iconicity are task-dependent, facilitating picture-naming but not word-to-sign translation, and e) neural effects of iconicity diminish with learning. Overall, the results reveal linguistic consequences for grounding language in the body that shape the structure of the lexicon, but neural effects of iconicity may only occur under certain circumstances.
