Does feedback targeting text comprehension trigger the use of reading strategies or changes in readers' attitudes? A meta-analysis
Our previous meta-analysis (Swart et al., 2019) had shown that feedback targeting text comprehension given when students perform a reading task positively influences learning from text. So far, differences in the effects of feedback were explained by design features, such as the timing and richness…

Learning-based Representations of High-dimensional CAE Models for Automotive Design Optimization
In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Roy de Kleijn: ‘Fetching a glass of water is extremely difficult for a robot’
Training a robot in a real-life environment is more or less impossible. Computer scientist and psychologist Roy de Kleijn switched to training in a simulated, virtual one instead. ‘You do have a reality gap, but the more precisely you train the robot, the better it is in practice.’ His inspiration:…

Individual choice repetition biases arise from persistent dynamics in parietal cortex
Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…
