Addressing Change: Perceptions of Threat in Today's World
The goal of this symposium is to have University of Minnesota graduate students from a broad range of programs (e.g. Child Psychology, Economics, Business, Neuroscience, etc.) present their work as it pertains to perception of threat in today's changing world. The symposium will be structured in order to present research that considers the causes and/or consequences of new sources of threat, as well as the nature of the responses necessary to preserve the future security of society.
"Neural correlates of statistical learning in adults and infants"
Since the initial demonstrations of statistical learning two decades ago, a variety of questions have been raised about the neural mechanism(s) that support these behavioral findings. Studies of statistical learning in adults using fMRI have focused on the outcome of the implicit extraction process -- i.e., differential activation to structured and unstructured test items during a post-learning recognition phase. I will summarize several fMRI studies that focus on the learning phase itself, using both auditory (temporal) stimuli and visual (temporal and spatial) stimuli. Because fMRI is extremely difficult to use with infants, I will also summarize some recent work that uses fNIRS (functional near-infrared spectroscopy) to study basic aspects of learning in 6-month-olds. These findings suggest some fundamental differences between how the infant and adult brain respond to sensory information, as well as some commonalities about how the infant and adult brain respond to violations of learned stimulus co-occurrences.
