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.
The introduction of computer workstations into the medical interview process makes it important to consider the impact of such technology on older patients as well as new types of interfaces that may better suit the needs of older adults.
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.
Language interpretation is often assumed to be incremental. However, our studies of quantifier expressions in isolated sentences found N400 event-related brain potential (ERP) evidence for partial but not full immediate quantifier interpretation (Urbach & Kutas, 2010). Here we tested similar quantifier expressions in pragmatically supporting discourse contexts (Alex was an unusual toddler. Most/Few kids prefer sweets/vegetables …) while participants made plausibility judgments (Experiment 1) or read for comprehension (Experiment 2). Control Experiments 3A (plausibility) and 3B (comprehension) removed the discourse contexts. Quantifiers always modulated typical and/or atypical word N400 amplitudes. However, the real-time N400 effects only in Experiment 2 mirrored offline quantifier and typicality crossover interaction effects for plausibility ratings and cloze probabilities. We conclude that quantifier expressions can be interpreted fully and immediately, though pragmatic and task variables appear to impact the speed and/or depth of quantifier interpretation.
This course will cover theoretical foundations and practical applications of signal processing to neural data. Topics include EEG/field potential methods (filtering, Fourier (spectral) analysis, coherence) and spike train analysis (reverse correlation, spike sorting, multi-electrode recordings). Some applications to neural imaging (optical microscopy, fMRI) data will also be discussed.

In this seminar we examine the development of social cognition in human ontogeny and examine similarities and differences between human socio-cognitive skills and those of other animals, great apes, birds and dogs in particular. We will focus mostly on infant and preschoolsers and on the principal building blocks of social cognition that pave the way to becoming competent members of a community. We start by examining the development of gaze following and voice following, the capacity to engage in joint attention and to communicate through gestures, specifically, pointing, during the first and second year of life. We then explore the role that human prosocial tendencies play in our capacity to carry out social lives and care for others, the complexity and importance of imitation for cultural transmission and how group mentality and group biases emerge. We then discuss how cultural transmission relies on conformity, normativity and on collaboration to construct and sustain social institutions and address how concerns such as fairness, procedural justice and ultimately our moral compass develop and to what degree they differ between human and non-human animals.

Interaction Design Startup: In this course, students will learn tools and processes for innovating novel business concepts to solve problems involving the interaction between humans and technology. Students will work with an interdisciplinary team to understand unmet user needs and to create a value proposition that balances technical feasibility, financial viability, and desirability. Ultimately, student teams will prototype a novel mobile information service, write a business plan, and produce a video sketch suitable for launching a crowdfunding campaign. To inform the innovation process, students will learn new techniques for leveraging social media and crowdsourcing to discover users' needs and to obtain feedback on preliminary concepts. Selected readings will cover ubiquitous computing, service design, business modeling, creativity methods, crowdsourcing, and crowdfunding. Pre-req: Cogs 120/CSE 170 or Dsgn 1.

The course explores the intersection of social behavior and computational systems. The growth of online environments like Facebook, Wikipedia, Twitter, Instagram, WhatApp, blogs, online support groups, open-source development projects, and crowdsourcing platforms shows that web technology is no longer just about delivering information, but also connecting people. Students will examine a range of social, technical, and business challenges related to social computing, and learn how to use tools to analyze, design, and build online communities. Course work will include lectures, class discussion, homework, class presentations, and a group research or design project. Pre-req: Cogs 120/CSE 170 or Dsgn 1.

When speaking to another person, we tailor our speech production based on information we know about that person: for example, you probably don't use the same vocabulary with a professor as you do with a 2-year-old. This project will investigate how specific this adaptation in the speech production system is. ...
