Title: Spatial Perception Is Action-Specific: Softballs Look Bigger to Batters Who Are Hitting Better Than Others

Abstract: Perception of the surrounding environment is shaped by a person’s body and ability to act within the environment. For example, hills appear steeper and distances appear farther to people who are obese, lack physical fitness, or are fatigued.  Sports targets appear bigger and slower to athletes who are playing better than others. Even though the optical information processed by the eye is exactly the same, target objects look different across perceivers and across situations as a function of the perceiver’s ability to act. This research calls for changes to current theories of spatial perception to incorporate the body and its actions as an influential source of information.

Title: Question Generation, More Than a Syntactic Transformation

Abstract: In this talk, I will focus on the role that questions play in human communication. Most of the data used in NLP has been WSJ and other expository text, with questions underrepresented in our data, to the extent that there are excellent parsers in existence that simply fail to parse the simplest question. The role of questions in automated tutoring systems has been explored, but only as needed for a specific domain. As we move to building NLP systems that understand and take part in general conversation, however, it is a good time to get curious about how questions are formulated and what they reveal about the underlying grounding of the conversation. I will review three related studies of question generation: determining the question focus given a sentence, question formulation with scope beyond the sentence, and question generation for images. For each of these topics, we demonstrate that question generation is not a matter of syntactic transformation, but rather presents a challenge to identify what the focus of the question should be, distinguishing what is in a question from what is understood or observed. We hope to use our study of questions to learn more about what people choose to be curious about, using only a small set of question words to explore the wide range of our experience.

INC 5 Year Anniversary Talk **NOTE LOCATION CHANGE: Center for Innovation & Creativity (1777 Exposition Dr. Bldr)

Join INC scientists as we celebrate our 5th anniversary and upgraded facilities. Dr. Marie Banich, Professor of Psychology and Executive Director of INC, will give an overview of brain imaging research at the INC. Drs. Angela Bryan, Tor Wager and McKell Carter will discuss and take questions regarding their research on aging and exercise, pain, and autism and social decision making. In addition, we will have ongoing tours of the INC facilities. Please RSVP by filling out the brief registration form:

Title: Linguistic Typology Meets Universal Dependencies - From Teaching Syntax to Annotating Digital Corpora

Abstract: Current work on universal dependency schemes in NLP do not make reference to the extensive typological research on language universals, but could benefit since many principles are shared between the two enterprises. I propose a revision of the dependency types in the Universal Dependencies scheme (UD 2014; Nivre 2015) based on the UD principles of lexicalism and content word to content word dependencies, and four principles derived from contemporary typological theory: dependencies should be based primarily on universal construction types over language-specific strategies; syntactic dependency labels should match lexical feature names for the same function; dependencies should be based on the information packaging function of constructions, not lexical semantic types; and dependencies should distinguish the “levels” of the functional dependency tree. The proposed revisions are based on a typological annotation scheme developed, and continuing to be developed, for teaching syntax to undergraduates at the University of New Mexico.

Title: Dissecting Prefrontal Circuits That Mediate Resilience

Abstract: The ability to exert behavioral control over an adverse event both blunts the behavioral and neurochemical impact of that event, and also blunts responses to future adverse events even if they are quite different. This talk will review research (in rodents) that indicates that the resilience-inducing impact of control is mediated by three separable and distinct prefrontal circuits—a prefrontal-striatal circuit that detects control and prefrontal-brainstem (DRN) and prefrontal limbic (amygdala) circuits that uses this detection information to blunt the impact of the adverse event on stressor-sensitive brainstem and limbic structures. These prefrontal circuits utilize different and non-overlapping prefrontal cells, and control induces plasticity selectively in the prefrontal-brainstem and prefrontal limbic circuit, thereby conferring protection in the future (resilience). Other issues to be discussed include whether all sequelae of aversive events are blunted or whether there is selectivity/specificity and whether all resilience-inducing experiential variables utilize this same prefrontal circuitry.
