This classic problem of perception in practical work situations was introduced in a study by Sumby & Pollack in 1954. Their question remains vital. Their account calibrated a perceiver\u2019s ability to take advantage at every degree of intelligibility of an opportunity to view the talker. Today\u2019s accounts often treat a perceiver as a deaf viewer bound to a blind listener, puzzling through the differing phonetic impressions which result from such different sensory opportunities. Other accounts suppose that the incommensurate dimensions of visual and auditory sensation are recoded into a hypothetically common amodal metric to permit phonetic analysis. Almost every account derives its evidence from small inventories of test items presented under minimal uncertainty, and consider the role of phoneme incidence to guide perceptual analysis. I will discuss new evidence from our laboratory of intelligible audiovisual presentation of speech, using auditory and visual components which are unintelligible presented individually. Perceivers reported their impressions of the utterances in open set transcription under minimally constrained conditions of uncertainty. Such phenomena are consistent with primitive intersensory combination on which perceptual analysis of audiovisual speech might truly depend.\n\nAbout the speaker: \nRobert E. Remez is Professor of Psychology at Barnard College, Columbia University, where he has taught since 1980. A native New Yorker, Robert was a Predoctoral Research Trainee at Haskins Laboratories in New Haven, and received the doctorate in 1978 from the University of Connecticut. He received the Bachelor of Arts degree in 1971 from Brandeis University. At Barnard, he has held an Ann Whitney Olin Chair, has been Chair of the Departments of Psychology and Sociology, and is Chair of the Columbia University Seminar on Language & Cognition. He is co-editor of both the first and second edition of the Handbook of Speech Perception, and was Associate Editor of the journals Perception & Psychophysics and the Journal of Experimental Psychology: Human Perception and Performance. In service to the research community, he was a member of the Committee of Visitors for the Social, Behavioral and Economic Sciences of the National Science Foundation, and was a sitting member of the Communication Sciences Study Section of the Division of Research Grants and the Language and Communication Study Section of the Center for Scientific Review of the National Institutes of Health. He has been elected a Fellow of the Acoustical Society of America, the Association for Psychological Science, the American Psychological Association, the American Association for the Advancement of Science, and the Psychonomic Society. The Speech Perception Lab at Barnard has been supported by grants from the National Institute of Mental Health, the National Institute of Neurological Disorders and Stroke, the National Science Foundation, and a longstanding grant from the National Institute on Deafness and Other Communication Disorders.", "occurrence_notes":null, "guid":"145947-21898170@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/145947", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"Talk- Room 4448, Reception- Third Floor Terrace", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Psychology Departmental","conference"], "website":"", "sponsors":[ { "group_name":"Department of Psychology", "group_id":"3615", "website":"http:\/\/www.lsa.umich.edu\/psych\/" }, { "group_name":"Cognition & Cognitive Neuroscience", "group_id":"3664", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/02\/event_145947_original-2.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/02\/crop-event_145947_original-2.png" }, "occurrence_count":1, "first_occurrence":21898170 } , "147044-21900272": { "datetime_modified":"20260417T132028", "datetime_start":"20260417T140000", "datetime_end":"20260417T150000", "has_end_time":1, "date_start":"2026-04-17", "date_end":"2026-04-17", "time_start":"14:00:00", "time_end":"15:00:00", "time_zone":"America\/Detroit", "event_title":"Journey Lecture with Tim Johnson, PhD", "occurrence_title":"", "combined_title":"Journey Lecture with Tim Johnson, PhD", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"The Biostatistics Department is happy to present Journey Lectures, which are light-hearted, non-technical talks by distinguished Biostatistics faculty describing their career paths.\nJoin us on\u00a0Friday, April 17\u00a0to learn about the journey taken to Michigan Biostatistics by\u00a0Tim Johnson, PhD.\u00a0\nDiscover how Tim's journey in biostatistics began in California, where he studied mathematics at UC Riverside, worked as a software engineer, and later earned his PhD in Biostatistics at UCLA.

They proved that the associated double Edelman\u2013 Greene coefficients, the double Schur expansion of these functions, are positive, a result later refined by Anderson. They further asked for a combinatorial proof of this positivity. We provide the first such proof, together with a combinatorial formula that manifests the finer positivity established by Anderson. Our formula is built from two combinatorial models: bumpless pipedreams and increasing chains in the Bruhat order. The proof relies on three key ingredients: a correspondence between these two models, a natural subdivision of bumpless pipedreams, and a symmetry property of increasing chains.

For general \\emph{belief restrictions}, we characterize the set of incentive compatible direct transfer mechanisms in general environments with interdependent values. Based on a \\emph{first-order approach}, we obtain a design principle to attain incentive compatibility via `belief-based' terms. In environments that satisfy a property of \\emph{generalized independence}, our results imply a \\emph{robust} version of \\emph{revenue equivalence}. Extending the notion of correlated information, we introduce a notion of \\emph{comovement} between types and beliefs, defined based on a moment condition. Under comovement, we characterize the full set of `belief-based' terms. Based on this, we show that from Bayesian settings the following result extends to this fairly mild restriction on beliefs: any allocation rule can be implemented, even in environments without single-crossing or monotonicity. However, full rent extraction need not follow. Information rents typically remain, and they decrease monotonically as the robustness requirement is weakened.", "occurrence_notes":null, "guid":"143384-21892974@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/143384", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4300", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["Theory","seminar","Economics"], "website":"http:\/\/www.lsa.umich.edu\/econ", "sponsors":[ { "group_name":"Department of Economics", "group_id":"3302", "website":"http:\/\/www.lsa.umich.edu\/econ" }, { "group_name":"Economic Theory", "group_id":"3555", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/04\/event_143384_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/04\/event_143384_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21892974 } , "136610-21893495": { "datetime_modified":"20260417T142029", "datetime_start":"20260417T143000", "datetime_end":"20260417T163000", "has_end_time":1, "date_start":"2026-04-17", "date_end":"2026-04-17", "time_start":"14:30:00", "time_end":"16:30:00", "time_zone":"America\/Detroit", "event_title":"SAPAC GROWE: Engendering Respectful Communities Workshops - SY25 - 26", "occurrence_title":"LSA - Engendering Respectful Communities (ERC) Open Workshop", "combined_title":"SAPAC GROWE: Engendering Respectful Communities Workshops - SY25 - 26: LSA - Engendering Respectful Communities (ERC) Open Workshop", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Engendering Respectful Communities (ERC) is a one session workshop that engages graduate students in meaningful dialogue about various forms of sexual misconduct they may encounter in both professional and social spaces, and provides resources for intervention or support in such circumstances.The primary goal of the workshop is to address complexities experienced by graduate students as they engage in bystander intervention, so that participants gain an increase in awareness of barriers to action and familiarity with strategic planning to overcome them. The workshop also introduces participants to on-campus resources and provides knowledge on how sexual misconduct can unfold in graduate-specific settings.The ERC workshop uses small-group circles intended to promote active reflection and space to build community. The procedure of circles is introduced at the beginning of the workshop in order to help participants get used to the process, which they do through a circle for introductions and value-sharing for the workshop space. These circles depict various, realistic scenarios related to sexual misconduct within the graduate community. The circle process allows circle members to process the monologues, reflect on complexities with identity and power dynamics within them, name potential barriers to intervention, and think of various ways in which they might respond if faced with similar situations. The circles provide a way to foster collective building of ideas, where participants learn from one another and all input is equally valued. Participants are encouraged to share but can always pass if desired, creating an environment where participation is open but not forced. Due to the participatory nature of the workshop, if you are to arrive more than 20 minutes late, we will ask you to re-register for another workshop session.If you have any questions about or concerns with taking this workshop, or are in need of an exemption, please contact jhippe@umich.edu or fill out this\u00a0form. We know some students come to campus having already experienced harm. If you have circumstances that make completing this course challenging, please reach out to the GROPWE team. SAPAC GROWE provides exemptions to the ERC workshop (where requirements are set in place) on a case by case basis. The Program Manager will communicate with students requesting exemptions via email and\/or meet with students via zoom meetings to discuss their need for exemptions and provide any relevant and necessary resources.", "occurrence_notes":null, "guid":"136610-21893495@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/136610", "building_id":"", "building_name":"", "campus_maps_id":"", "room":"", "location_name":"LSA 3254; 500 S State St, Ann Arbor, MI 48109", "has_livestream":0, "cost":"", "tags":["Sessions"], "website":"https:\/\/sessions.studentlife.umich.edu\/p\/track\/14683", "sponsors":[ { "group_name":"Sessions @ Michigan", "group_id":"4791", "website":"https:\/\/sessions.studentlife.umich.edu\/" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21893495 } }
