In research with animals, my students and I use rats to study the role played by various neurotransmitters, especially dopamine, in reward-related incentive learning.
|
|
|
|
My primary research interests are in the perception, exploration and retention of information from complex, natural stimuli (i.e., real-world scenes).

In our laboratory we are interested in the perceptual, cognitive, and emotional processes involved in music appreciation and understanding. Recent work has focused on individual differences in musical and prosodic skills and sensitivities. We study such topics as absolute pitch, tone deafness, effects of music lessons on nonmusical cognitive skills, musical dyslexia, aging and music, amusia following stroke, and sparing of musical memories in Alzheimer's Disease.

The aim of research in the Cognition and Action Lab is to understand the cognitive and computational processes underlying movement control and learning.
|
|
|
|
I focus on the processes recruited as utterances (syllables, words and sentences) are transformed from an acoustic signal to meaning, and how these processes are organized in the brain.
|
|
|
|
My research is concerned with the neural circuits responsible for mediating fear as a useful adaptation, as well as with how altered brain function might promote maladaptive levels of fear.
|
|
|
|
My research concerns human performance and how to model it.
|
|
|
|
My general research interest is the understanding of the processes of speech production and speech perception.
|
|
|
|
My research is directed towards understanding the neural and psychological interface between motivation and cognition,- or how rewarding stimuli influence learning.
|
|
|
|
I am interested in how the visual system works and how it serves us to interact with objects and people.
|
|
|
|
Research is currently focused on training of attentional control, how attentional control shapes perceptual experience, working memory and attentional control, attention control in a virtual reality environment, and cortical mechanisms underlying attentional control.
