Jennifer Coppola wins the Lisa M. Quesenberry Scholarship
April 22, 2015—The Lisa M. Quesenberry Scholarship Fund was established by Irvin and Mary Ann Quesenberry and Kathryn Quesenberry to memorialize the accomplishments of their daughter and sister, Lisa M. Quesenberry. The scholarship is designed to provide research or study awards to motivated graduate students. The award is targeted to female graduate student who overcame significant personal hurdles to pursue their education. Jennifer is currently a first-year graduate student with Anita Disney. She received her undergraduate degree from the Ohio State University. Not only is Jennifer the first in her family to enter a PhD program, but she is the first to go to college and the first to finish high school. Congratulations, Jennifer.
May Shen and Yao Jiang win The William F. Hodges Teaching Assistant Award
April 22, 2015—This award recognizes outstanding achievement as a teaching assistant by a graduate student in the Department of Psychology. William Hodges was an undergraduate and a graduate student at Vanderbilt in the 1960s. After his untimely death in 1992, family and friends established the William F. Hodges Teaching Assistant Award at Vanderbilt to honor outstanding teaching assistants in the department. May Shen is a graduate student with Thomas Palmeri. She has completed a Certificate in College Teaching from the Center for Teaching and has TAed for a wide array of courses in the department, including PSY208 (Principles of Experimental Design), PSY209 (Quantitative Methods), and PSY225 (Cognitive Psychology); this semester, she is TAing for a statistics course in Psychology and Human Development. Adriane Seiffert, for whom May TAed in PSY208 and PSY209, noted that her work was “exemplary in both courses”, and that students commented that “she was responsive and helpful - gave exact answers to questions”, “conveyed the material in a way she knew would be effective, logical and memorable”. Geoff Woodman, for whom May TAed in PSY225, noted that she “jumped on a week’s worth of lectures when given the opportunity.” Yao Jiang is a graduate student with Vivien Casagrande. She most recently TAed for the introductory NSC201 Neuroscience course. Students commented that Yao is “very energetic and very very smart”, and that “her review sessions helped so much”. Dr. Leslie Smith, who Yao TAed for in Neuroscience, commented that “She was always eager to volunteer for jobs as they sprung up during the semester. Her exam reviews were spot on, and students raved about her upbeat, enthusiastic personality during these sessions. … I truly enjoyed working with her. She was so positive, a breath of fresh air every lecture day.” Congratulations, May and Yao.
Rob Reinhart wins The Pat Burns Memorial Graduate Student Research Award
April 22, 2015—This award is named after Pat Burns, who was Education Coordinator in the Department of Psychology until her death several years ago; Pat touched generations of doctoral students during her nearly four decades of service to Vanderbilt University. In memory of her tireless efforts to help guide our students through all phases of their graduate education, this award recognizes outstanding achievement in research by a graduate student in the department. This year’s winner, Rob Reinhart, is a PhD student working with Geoff Woodman, Jeff Schall, and Sohee Park. He received his BA from the University of Connecticut. Rob was awarded a pre-doctoral NRSA fellowship and already has 12 peer-reviewed publications in top journals, such Psychological Science, Proceedings of the National Academy of Science, Cerebral Cortex, and Journal of Neuroscience. Congratulations, Rob.

Suppressive neural mechanisms: from perception to intelligence
Perception operates on an immense amount of incoming information that greatly exceeds the brain's processing capacity. Because of this fundamental limitation, the ability to suppress irrelevant information is a key determinant of perceptual efficiency. Here, I will present a series of studies investigating suppressive mechanisms in visual motion processing, namely perceptual suppression of large, background-like motions. These spatial suppression mechanisms are adaptive, operating only when sensory inputs are sufficiently robust to guarantee visibility. Converging correlational and causal evidence links these behavioral results with inhibitory center-surround mechanisms, namely those in cortical area MT.
What are functional roles of spatial suppression? Spatial suppression is weaker in old age and schizophrenia—as evident by paradoxically better-than-normal direction discriminations of large moving stimuli. Moreover, these subjects also exhibit deficits in figure-ground segregation, suggesting a functional connection. In recent studies, we report direct experimental evidence for a functional link between spatial suppression and figure-ground segregation
Finally, I will argue that the ability to suppress information is a fundamental neural process that applies not only to perception but also to cognition in general. Supporting this argument, we find that individual differences in spatial suppression of motion signals strongly predict individual variations in WAIS IQ scores (r = 0.71).

Emotion inside out: From cartoon neuroscience to the predictive brain
This talk will review theory and research to reveal the surprising ways in which the brain uses prediction to construct experiences and perceptions of emotion. Two themes will be covered: (1) the shift from typological thinking (an emotion has a particular facial expression and autonomic fingerprint) to population thinking (an emotion word names a population of unique instances tailored to the specifics of the immediate situation); (2) the shift from essentialism (all instances of an emotion category share an underlying neural circuit) to degeneracy (instances of an emotion category are constructed as different configurations within the brain’s functional architecture of interacting domain-general core networks). These themes not only explain the nature of emotion, but they represent a shift in the scientific paradigm for mapping brain structure and function to mental categories. They dissolve the artificial boundaries between cognition, perception, emotion, and action, and between categorization, prediction, and memory, to unify the mind, providing new insights for understanding mental disorders, neurodegenerative diseases, and even physical illness.

Saccade vigor encodes subjective value of reward
Until close to the end of the 20th century, saccade speed was considered strictly a function of movement size (the so-called “main sequence”). More recent studies suggest that saccade vigor is not strictly dictated by amplitude. Motivational factors such as reward also affect saccade vigor. For instance, monkeys make faster saccades to targets promising juice reward than to non-rewarded targets. Similarly, humans make faster saccades to faces than to visual noise. We wanted to determine whether subjective value of reward, assessed during a temporal discounting task, affected saccade vigor. We asked 60 volunteers to complete a standard temporal discounting task, in which they chose between a small reward to be delivered immediately, and a larger reward delivered after 30 days. We manipulated the amounts of immediate and delayed reward offered over 120 trials, and estimated each subject’s discount rate. While subjects completed the task, we monitored their eye movements with video-oculography. It is important to note that subjects’ saccades did not affect trial outcome; saccades only served as a means of acquiring information about the rewards offered. We found that, after subjects made their decision, within-trial saccade vigor dropped immediately by roughly 4%. Among the saccades made just before and just after the decision, saccades to the preferred option were more vigorous than saccades to the non-preferred option. The disparity between vigor of saccades to the two options became larger as the difference in the subjective values of the two options increased. Therefore, during decision-making, the subjective value that the brain assigned to a stimulus influenced the vigor with which the eyes moved toward that stimulus.
