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.
Bottlenose dolphins are large-brained, social mammals that have an elaborate vocal repertoire which is, as yet, poorly understood. Using extensive audio-video recordings of a dolphin community at Brookfield Zoo, Chicago, we are investigating communication and social cognition in these animals. Interns on this project will be trained to score video ...
Vehicles are collecting more and more information that can in principle help a driver control a vehicle more safely. But when is more information helpful, and when is it distracting? The Language and Cognition Lab (http://www.cogsci.ucsd.edu/~bkbergen/lcl/) is looking for outstanding students interested in getting involved with experimental research on driving ...
The Embodied Cognition lab is interested in understanding cognition from the perspective of the embodied mind, investigating how the peculiarities of our bodies and how our experiences in and interactions with the world around us give rise to our understanding of abstract concepts such as time. In this particular study, ...
