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.
The brain is able to acquire information about an unknown word’s meaning from a highly constraining
sentence context with minimal exposure. In this study, we investigate the potential contributions of
the cerebral hemispheres to this ability. Undergraduates first read weakly or strongly constraining
sentences completed by known or unknown (novel) words. Subsequently, their knowledge of the
previously exposed words was assessed via a lexical decision task in which each word served as visual
primes for lateralized target words that varied in their semantic relationship to the primes (unrelated,
identical or synonymous). As expected, smaller N400 amplitudes were seen for target words preceded
by identical (vs. unrelated) known word primes, regardless of visual field of presentation. When
Unknown words served as primes, N400 reductions to synonymous target words were observed only if
the prime had appeared under High sentential constraint; targets appearing in the LVF/RH elicited a
small N400 effect and modulation of a subsequent late positivity whereas those in the RVF/LH elicited
modulation on the late positivity only. Unknown words initially seen in Low constraint contexts
showed priming effects only in a late positivity and only in the RVF/LH. Strength of contextual
constraint clearly seems to impact the hemispheres’ rapid acquisition of novel word meanings. N400
modulation for novel words under strong contextual constraint in the LVH/RH suggests that fast-
mapped lexical representations may initially activate meanings that are weakly, distantly, associatively
or thematically-related. More extensive and bilateral semantic processing seems to occur at longer
processing latencies (post-N400).
The role of cognition and computation in the development of state-of-the art technologies such as human computational interaction in aviation, air traffic control, medical diagnosis, robotics and telerobotics, and the design and engineering of cognitive artifacts.
How do the languages we speak shape the ways we think? This course examines interrelationships between language & thought. Do people who speak different languages think differently? Does learning new languages change the way you think? Do polyglots think differently when speaking different languages? Are some thoughts unthinkable without language? The course will bring together ideas and findings from psychology, linguistics, anthropology, communication, neuroscience, and philosophy.
We are evaluating two interventions for dyslexia that involve training the temporal dynamics of the visual system (magnocellular pathway) and the auditory system, and whether the two interventions together have super-additive effects. As a Research Assistant, you would be traveling to one or two of five participating local elementary schools ...
Can comprehending a sentence literally change how you see? What about the other way around? How is it that reading or hearing about an event can seemingly transport you to another place and make you feel like you are there? What are the psychological mechanisms that contribute to the meaning ...
Background sounds often interfere with spoken language comprehension and noise from nearby conversations can be particularly disruptive. We are conducting a new study to test whether multisensory training can, over time, enhance the ability to recognize speech in noisy environments.

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. ...
The uncanny valley hypothesis posits that when humanoid robots or animated characters look and act almost, but not perfectly, like actual human beings, the human reaction can be negative. Although anecdotal evidence for this phenomenon is abundant, scientific exploration has thus far been limited. Our lab studies the perception of ...
Rady Behavioral Lab is looking for research assistants: One project we are working on examines the whether people’s trait concern for the welfare of others moderates the relationship between the experience of power and different types of lying; another examines the effect of Facebook use on social interaction and cognition. ...
Very little is known about how people formulate the thoughts they want to convey through language. Some of the best evidence comes from what happens when speech production fails. The speech errors that people make can reveal subtle aspects of how they're planning what to say. The Language and Cognition ...
We study how the human brain processes language, including at the single word level and sentence level. Our primary methodology in this pursuit is to record event-related potentials (ERP) from the scalp. These brain potentials can provide a real-time window into the neural processes underlying language comprehension. One of our ...
Do bilinguals think differently in each of their languages? For instance, do Spanish-English bilinguals pay attention to different aspects of the world when performing a task in Spanish versus English? When they're performing a task in Spanish, do they show a bias towards Spanish-sounding names that disappears when they're performing ...

The Future is Now: Effects of Planning Ahead in Word Production and Comprehension
Although speech is produced sequentially, both speakers and listeners plan ahead: Speakers prepare words in advance to maintain a fluent speech rate, and listeners generate expectations about the meaning and form of upcoming words. In this talk, I will present my dissertation research on how these linguistic feats are accomplished. Study 1 establishes that selecting a word for production requires domain-general attentional resources and that differences ...

Remediation of abnormal visual motion processing in dyslexics significantly improves reading, attention, and working memory
Temporal processing deficits resulting from sluggish magnocellular pathways in dorsal stream cortical areas have been shown to be a key factor limiting reading performance in dyslexics. To investigate the efficacy of reading interventions designed to improve temporal processing speed, we performed a randomized trial on dyslexic second graders in four public elementary schools in San Diego, comparing the school’s regular reading intervention (control ...

Photoacoustic Tomography: Beat Optical Diffusion and Diffraction
We develop photoacoustic imaging technologies for in vivo early-cancer detection and functional, metabolic, molecular, and histologic imaging by physically combining non-ionizing electromagnetic and ultrasonic waves. Unlike ionizing x-ray radiation, non-ionizing electromagnetic waves—such as optical and radio waves—pose no health hazard and reveal new contrast mechanisms. Unfortunately, electromagnetic waves in the non-ionizing spectral region do not penetrate biological tissue in straight paths as x-rays do. Consequently, high-resolution tomography based on non-ionizing electromagnetic waves ...
