"I am doing work on human sexual psychophysiology. I am interested in the origins of patterns of sexual attraction and sexual arousal, in other words what turns people on and why. Most recently I have been looking at the role of learning processes and alcohol use as triggers for sexual compulsivity and sexual risk taking. I also have an animal lab that is set up to look at the neurochemical correlates of behavior. My original interest had been in developmental differences in learning in rats and the role of monoamine and neuropeptide transmitters in such ontogenetic differences. Students in this lab also work on a broader range of projects, examining how various drugs affect behavior, many focusing on drugs of abuse. Both of these areas of research involve inter- and intra- departmental cooperation, i.e., I have worked with other psychology and neuroscience faculty and students from the biology, biochemistry, and the chemistry departments."

What Students Say
"The energy and enthusiasm Professor Hoffmann brings to the classroom is immeasurable. Her obvious interest in the material is reflected in her fast-paced and engrossing lectures. Lectures are never strictly textbook-Heather relays valuable information from several creative and perhaps even unorthodox sources. She always asks questions that encourage the class to question concepts and contemplate their implications."

Through his music capstone project, Nate Beck -- who has a minor in business and management -- finds that the processes of brand management and music composition have more in common than you'd probably expect.
Baby talk is serious business for senior Megan Beney, a double major in music and anthropology and sociology. Her Honors research focuses on the musical qualities of the ways that people talk to infants.
Leading up to a worldwide event -- Gun Control Theatre Action Week, May 27 through June 2 -- a play by Knox College theatre professor Neil Blackadder is selected for a new collection, "24 Gun Control Plays."
