Graduate students from all areas within the psychological and brain sciences presented their posters on December 8, 2025 at the IU McCalla School’s exhibition space on campus. The space was full to the brim with the voices of graduate students explaining their posters, conversation and camaraderie, and topics too numerous to list, but among them were the following:
LeCoder: A Large-Scale Automated Coder for Coding Errors in Word Production Tasks. In the lab of Professor Bonnie Nozari, Shanhua Hu presented a tool that would quickly and accurately code and categorize the speech errors that enable the lab to better understand the architecture of the language production system.
We often begin to speak like those with whom we are speaking. In Transfer of Statistical Learning from Speech Perception to Production Transfers to Reading, Kyle Huffaker, also in Nozari’s lab, explored the question of “How far does this change in our speech go?” and “Does it affect our representations of language when we read?”
Structural Views of Prejudice Predict Engagement in Collective Action. What motivates an individual to participate in collective action? Graduate student Cheryl Nong and PBS Professor Dorainne Green propose that the belief in the systemic nature of prejudice and injustice makes one more likely to engage in social activism.
Does Cannabis Use Moderate the Relationship between Psychotic-Like Experiences and Stress-Related Autonomic Arousal? Graduate student Jacob Nudelman, a student of Professor Krista Wisner in the Clinical and Cognitive Neuroscience Center explores the way cannabis use alters the relationship between stress and psychotic-like experiences.
Do Latinas Experience Cultural Mismatch in STEM. Graduate student Maria Velasco and her mentor Professor Amanda Diekman investigate the potential mismatch between STEM culture’s sense of independent individuals and an interdependent Latina self-concept.
Parent Motivational Beliefs Predict Autonomy-Supportive Behaviors during Spatial Play. Graduate student Mariana Sosa Ferri in Professor Elizabeth Gunderson’s Cognition and Learning Lab, explores the effect of parents’ autonomy-supportive behavior on children’s spatial abilities.
Limits of the Wisdom of the Crowd. Graduate students Daniil Azarov in the lab of Professor Rob Goldstone tests the limits of the notion that the Wisdom of the Crowd leads to an accurate answer to certain questions by examining the Wisdom of the Inner Crowd, the aggregated answers of a single individual over time. Does this Wisdom of the Inner Crowd likewise lead to greater accuracy than any single individual judgement?
