Sensorimotor Variability and Early Cognition

A recent study by Denisova and Wolpert (2024) investigates how early sensorimotor features relate to cognitive differences in toddlers diagnosed with autism spectrum disorder (ASD). By examining over 1,000 children with varying IQ levels, the researchers reveal how sensorimotor variability impacts behaviors linked to autism, providing valuable insights for individualized …

Theoretical Framework for Bayesian Hierarchical 2PLM with ADVI

This article discusses a Bayesian hierarchical framework for the Two-Parameter Logistic (2PL) Item Response Theory (IRT) model. By introducing hierarchical priors for both respondent abilities and item parameters, this method offers a detailed perspective on latent traits. Additionally, the use of Automatic Differentiation Variational Inference (ADVI) makes the approach scalable …
