How do humans conceptualize time? One clear pattern is that temporal concepts are based on spatial ones, however how this is done is not universally determined in the human brain and varies significantly across cultures.
What information can young children use to aid them in understanding spoken language? Recent work in the Creel lab shows that preschoolers are able to use who is talking to limit the set of things that person might talk about.
Though prediction has been proposed across a variety of neural domains, language has not traditionally been one of them - until recently. Using event-related brain potentials, we show that prediction is part and parcel of sentence comprehension.
Artificial agents such as humanoid robots and interactive animated characters are rapidly becoming participants in many aspects of social and cultural life. With applications in domains such as education and health care, we need to understand human factors guiding our perceptions of and interactions with these agents.
Inhibitory control is the ability to withhold or modify prepotent or planned actions that are no longer appropriate in a behavioral context. We are studying the computational and neurophysiological basis of inhibitory control in healthy individuals and those affected by conditions such as ADHD and stimulant abuse.
The ability to recall our experiences as they evolved over time is truly an impressive feat accomplished in large part through the working of a thumb-sized portion of the brain called the hippocampus. How the brain encodes memories is a difficult, but exciting and burgeoning area of neuroscientific research.
People drive more poorly when they're talking on the phone. What is it about having a conversation that interferes with steering, changing gears, and noticing brake lights?

ChronoViz is a system to aid annotation, visualization, navigation, and analysis of multimodal time-coded data. Exploiting interactive paper technology, ChronoViz also integrates researcher's paper notes into the composite data set. The goal is to decrease the time and effort required to analyze multimodal data by providing direct indexing and flexible mechanisms to control data exploration.
To re-establish picture-sentence verification—discredited possibly for its over-reliance on post-sentence response time (RT) measures—as a task for situated comprehension, we collected event-related brain potentials (ERPs) as participants read a subject-verb-object sentence, and RTs indicating whether or not the verb matched a previously depicted action. For mismatches (vs. matches), speeded RTs were longer, verb N400s over centro-parietal scalp larger, and ERPs to the object noun more negative. RTs (congruence effect) correlated inversely with the centro-parietal verb N400s, and positively with the object ERP congruence effects. Verb N400s, object ERPs, and verbal working memory scores predicted more variance in RT effects (50%) than N400s alone. Thus, (1) verification processing is not all post-sentence; (2) simple priming cannot account for these results; and (3) verification tasks can inform studies of situated comprehension
Speech carries both linguistic content – phonemes, words, sentences – and talker information, sometimes called ‘indexical information’. While talker variability materially affects language processing, it has historically been regarded as a curiosity rather than a central influence, possibly because talker variability does not fit with a conception of speech sounds as abstract categories. Despite this relegation to the periphery, a long history of research suggests that phoneme perception and talker perception are interrelated. The current review argues that speech perception itself may arise from phylogenetically earlier vocal recognition, and discusses evidence that many cues to talker identity are also cues to speech-sound identity. Rather than brushing talker differences aside, explicit examination of the role of talker variability and talker identity in language processing can illuminate our understanding of the origins of spoken language, and the nature of language representations themselves.
We review the discovery, characterization, and evolving use of the
N400, an event-related brain potential response linked to meaning
processing. We describe the elicitation of N400s by an impressive
range of stimulus types—including written, spoken, and signed words or
pseudowords; drawings, photos, and videos of faces, objects, and
actions; sounds; and mathematical symbols—and outline the sensitivity
of N400 amplitude (as its latency is remarkably constant) to
linguistic and nonlinguistic manipulations. We emphasize the
effectiveness of the N400 as a dependent variable for examining almost
every aspect of language processing and highlight its expanding use to
probe semantic memory and to determine how the neurocognitive system
dynamically and flexibly uses bottom-up and top-down information to
make sense of the world. We conclude with different theories of the
N400's functional significance and offer an N400-inspired
reconceptualization of how meaning processing might unfold.
This is an upper-level undergraduate course focused on the design of gesture-based intearction techniques. The course will cover original research in HCI on various gesture-based input techniques, including mouse, pen, touch, and whole-body interaction. Students will work in small teams to complete prototyping activities related to various gesture-based techniques.
Human language is unlike any other naturally occurring communication system. It’s expressive, flexible, and in principle limitless. It’s also dirty.
This class is an introduction to language through the lens of its dark underbelly. We’ll look at vulgarities, taboo words, and epithets. They will tell us a lot about how people learn language, how they pronounce words, how they put words together into sentences, how they understand meaning, and why language changes over time.
There are no prerequisites for this course. However, students who believe they could be offended by the study of swearing and other taboo language might not find this course appropriate for them, and are encouraged not to enroll.

The impact of implicit learning and development of conceptual knowledge in children with SLI
It has recently been suggested that specific language impairment (SLI) is a domain general deficit in implicit learning. Ullman and colleagues have argued that the implicit learning impairments in SLI are restricted to procedural learning impairments and that procedural learning deficits impact the acquisition and use of bound morphology and syntax; leaving the acquisition and use of the mental lexicon largely intact. Our recent work ...

Machine learning and AI via large scale brain simulations
By building large-scale simulations of cortical (brain) computations, can we enable revolutionary progress in AI and machine learning? Machine learning often works very well, but can be a lot of work to apply because it requires spending a long time engineering the input representation (or "features") for each specific problem. This is true for machine learning applications in vision, audio, text/NLP and other problems. To address this, researchers have recently ...
