Doebel innovating developmental science with an online, scalable meta-science platform for investigating cognitive development during early childhood

George Mason University Assistant Professor Sabine Doebel is developing an online, scalable meta-science platform to investigate cognitive development during early childhood. The project, GARDEN, aims to gather data from a diverse sample of preschoolers and assess young children's executive functioning.

Simulating cold sensation without actual cooling

Researchers developed a non-contact technology that simulates a cold sensation by leveraging human sensitivity to rapid temperature changes. The system uses air flow and light to rapidly switch between cold and warm stimuli, inducing a cold sensation while maintaining skin temperature fluctuations near zero.
