Title: The Mind Hidden in Our Hands
Abstract: Gesture is versatile in form and function.  Under certain circumstances, gesture can substitute for speech, and when it does, it embodies the properties of language that children themselves bring to language learning, and underscores the resilience of language itself. Under other circumstances, gesture can form a fully integrated system with speech.  When it does, it both predicts and promotes learning, and underscores the resilience of gesture in thinking. Together, these lines of research show how much of our minds is hidden in our hands.

Sept 25 — Alexander Todorov (Booth School of Business, Chicago).

Title: Modeling subjective visual evaluations

Abstract: People effortlessly and spontaneously evaluate stimuli in their environment. There are two challenges understanding these evaluations. The first challenge is that reducing a complex evaluation (e.g., “beautiful”) to the physical description of the stimulus is far from trivial, because the space of hypotheses of what perceptual features drive evaluations is infinitely large. My research group has developed data-driven computational methods that allow us to find a consistent mapping from features to evaluations. Although the original methods were developed for face evaluation, modern machine learning methods extend the approach to modeling evaluations of any visual category. The second challenge is that evaluations are highly idiosyncratic. In fact, statistical modeling shows that stable idiosyncratic preferences account for most of the variance of complex evaluations (e.g., more than 80% in the case of “trustworthiness”). These findings suggest that the mapping from features to evaluations is highly heterogeneous across people. Yet almost all existing models of evaluations are models of aggregated judgments, assuming consistent mapping across people and, essentially, masking idiosyncratic differences. I describe one approach of building models of evaluations of individual participants. The models are meaningful and reveal the diversity of human preferences.

               Title:  Problems of our own making: Exploration, insight, and identity.

               Abstract: Work on exploration is closely tied to work on rational learning. Researchers have proposed that humans are motivated to explore variously in the face of novelty, prediction error, information gaps, opportunities for information gain, uncertainty reduction, anticipatory utility, increased empowerment, and increased rates of learning progress. Although there are important distinctions among these accounts, they are united by the idea that organisms are motivated to build more accurate models of themselves and the world. I’ve long worked in the tradition of exploratory play as rational learning and I will present some of this work. However, I will also suggest that we should take an expansive view of the kind of behavior that exploration permits. Human motivation is vastly flexible: We can want to think about and explore anything, whether or not it has any apparent social, epistemic, or instrumental value. Indeed, much of what children (and adults) do involves inventing problems we don’t (otherwise) have and incurring unnecessary costs to obtain seemingly arbitrary rewards. Second, motivation cannot be easily decoupled from cognition. I will present some new work suggesting that social goals can affect not just what we choose to think about but what we can think about. I end by speculating about the connection between cultural variability, division of labor, and distinctively human motivation.

Title: Playing with musical rhythm: New frontiers in therapeutic interventions

Abstract: Rhythm is a fundamental aspect of human behavior, shaping the way we walk, speak, and interact with others. It tightly links perception and action through general-purpose cortico-subcortical networks. Individual differences in rhythmic abilities can now be assessed with standardized tools such as the Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA), revealing distinct profiles across healthy and clinical populations. Importantly, rhythm processing is often disrupted in conditions such as Parkinson’s disease and neurodevelopmental disorders (e.g., ADHD, developmental dyslexia, developmental stuttering). In recent years, research has shown that rhythmic skills are not only central to everyday life but can also be harnessed to support health and well-being. Translational research demonstrates that targeted rhythmic training can enhance motor performance and executive functions, paving the way for novel therapeutic approaches. In this talk, I will show how gamified rhythm interventions, which engage multisensory processes, ensure high compliance, and have shown feasibility and preliminary efficacy in both neurodegenerative and neurodevelopmental disorders. These serious games selectively improve rhythmic skills and may generalize to broader cognitive functions. Together, this work outlines a promising frontier where rhythm-based, technology-supported interventions can support rehabilitation in clinical populations.
