Welcome! I'm David Leland, assistant professor of psychology at UW-Eau Claire. I teach courses in general psychology and neuroscience, as well as one in my area of specialization, cognitive neuroscience. My laboratory (CHEEZ) uses electroencephalography (EEG) to study the neural underpinnings of cognition, motivation, and action. Below you can check out course offerings, lab information, some personal info, and my CV.

COURSES

Spring 2012

PSYC271 Methods of Research in Psychology

IDIS125 Introduction to Neuroscience (co-taught with biology Professor Daniel Janik)

Cognition & Human ElectroEncephalography Zone

		The CHEEZ uses EGI 64-channel hydrocel geodesic sensor nets for EEG recording and E-Prime for stimulus presentation and behavioral data collection. Of the student research assistants, newbies get the designation "Little cheez" while veteran lab members earn the title "Big cheez." The current lineup: Big cheez: Paige Jablonski, Jacob Bradley, Danielle Barber, Bea Soderholm Little cheez: Eric Hanley, Amy Johnson, Emily Vanlandschoot Currently, we are investigating the influence of motivation levels on brain indices of attention. While undergoing EEG recording, participants respond to certain stimuli and withhold response to others, with correct performance earning few points in some cases and more points in the other cases. Points increase participants' odds of winning a gift card at the end of the study, thus creating two incentive conditions (high and low) across which we can compare brain event-related potentials (ERPs) in response to those stimuli. Our primary interest is in the P3, a positive deflection (peak) in the ERP that is associated with attention to important, informative stimuli. The P3 is a powerful index of cognitive processing in healthy individuals and in psychopathology (e.g., alcoholism). We predict P3 amplitude (power) will be increased in the higher incentive condition. With this project, we aim to broaden our understanding of how motivational salience influences attention-related brain activity. Also, we have a funding proposal submitted to look at effects of drinking patterns and alcohol stimuli on attention-related aspects of the EEG. More generally, we are exploring options for alcohol-related research in light of the recent CDC report on binge drinking

PERSONAL

My  feed focuses on experimentation with food, music, and of course brains. Hobbies include: Playing the ukulele (check out U.K.E.--the Ukulele Klub of Eau Claire) Cooking (e.g., pizza) Very amateur photography and video editing Singing (e.g., karaoke, vocals for my friend Geoff's cover songs) Hand-drumming (congas, bongos) Hiking, biking, snowshoeing Various zany art/music projects Role-playing games (haven't played in years though--not enough time!) In June 2010 I won a contest to meet and interview Wayne Coyne of the Flaming Lips at the Bonnaroo music festival.  Here's the crazy braintastic video my wife and I created as our entry into the contest and here's MySpace's video documenting the experience. Also there's a set of pictures from our time there.
