In the current globalized world, innovation in science and technology are vital for economic competitiveness, quality of life, and national security. This trend is accelerating the increasing reliance on virtual teams and their collaborative effort to solve complex environmental, social and public health problems. To contend with these dynamic conditions, communication, and collaborative problem-solving (CPS) competencies have taken a principal role in educational policy, research, and technology. Adaptive educational technologies provide a platform to deliver personalized training to improve learners’ CPS skills. However, for these systems to optimally tailor instruction, they must have key insights into learners’ interaction dynamics and team behaviors. We have been exploring these properties by employing Group Communication Analysis (GCA), a computational linguistics methodology for quantifying and characterizing the socio-cognitive processes between learners in online interactions. This talk will focus on recent studies where we have used GCA to gain a deeper understanding of role ecologies, learning and problem-solving, and issues of inclusivity in digitally-mediated group interactions. The scalability of GCA opens the door for future research efforts directed towards improving collaborative competencies and creating more inclusive online interactions.

Scales are used in almost every psychological study. Sum (or average) scores of scales are a common approach yet computing sum scores when factor scores are more appropriate can reduce validity and stifle substantive theory. Recently, psychometric network analysis has emerged as another model, rapidly rising in use. The addition of network modeling raises further questions about the effects of when an inappropriate model is used to score scales. In this talk, I introduce network models, demonstrate the relationship between their parameters (e.g., communities, centralities) and factor model parameters (e.g., dimensions, loadings), and present a novel neural network algorithm to determine whether data are generated from a factor or network model. Using an empirical example, I demonstrate the potential consequences of applying the (in)appropriate model. I close with discussion on the importance of using the appropriate model (even when the stakes are low)

"In noisy environments, the human auditory system fills in speech sounds obscured by noise, a perceptual illusion known as phonemic (or auditory) restoration. The neural mechanisms allowing the brain to generate predictions that override ascending sensory information remain poorly understood. Using data from extracellular recordings of many neurons, we tested whether zebra finches (Taeniopygia guttata) exhibit patterns of activity consistent with the illusion of auditory restoration. We find that applying a linear decoder to occluded songs reveals the spectrotemporal structure of the missing syllables. Surprisingly, restoration occurs under anesthesia and for unfamiliar as well as familiar songs. These results show that circuit dynamics within the auditory system instantiate an internal model of the general structure of conspecific vocalizations that can fill in missing acoustic features in ambiguous stimuli, even in the absence of top-down attention."

In recent years there has been explosive growth in imaging studies in medical and public health research. It is of great interest to understand how subject-level characteristics, including clinic variables and genetic factors, influence imaging phenotypes. In this talk, the speaker will present a class of image-on-scalar regression models for imaging responses and scalar predictors. Through flexible multivariate splines over triangulations, the proposed method can handle the irregular domain of the objects of interest on the images and other characteristics of images. The proposed method can provide the pointwise confidence intervals and data-driven simultaneous confidence corridors to access the estimation uncertainty and automatically identify significant regions. The proposed method is applied to the spatially normalized Positron Emission Tomography data of Alzheimer's Disease Neuroimaging Initiative.

Social scientists have long been interested in the origin, content, and effects of group stereotypes. A vast literature has identified several different ways that stereotypes can influence social judgment and behavior. This talk will focus on a growing body of research into how stereotypes can play a distinct, metacognitive role in influencing perceptions. In particular, evidence from several studies supports that stereotypes can validate or increase how certain we are of our perceptions of others and ourselves. Furthermore, these findings suggest that this metacognitive validation phenomenon may carry important, downstream implications for people’s attitudes, beliefs, interests, and future behaviors.

This talk envisions some of the methodological possibilities that arise when traditional statistical practice is decoupled from its traditional scientific worldview and realigned with a qualitative mental model. The work described is motivated by perspectives, debates, and practices in socially inclusive research and mixed method research, within which the proposed methodology is expected to situate most well for use. The talk holds up Bayesian methodology for its potential consonance with a qualitative mental model, but in a form whose technical and foundational underpinnings are modified from traditional versions in order to emphasize conceptual flexibility and knowledge that is centered in community. Also discussed is a strategy for statistical reporting, derived from a concept called "pool-reduction," that is explicit in the tasks of decision-making.
