Different technologies have been developed to help parents and caregivers address pediatric vehicular heatstroke (PVH), or scenarios where a child dies from overheating in an unattended motor vehicle. In a new study, researchers identified exemplar PVH scenarios that have occurred during recent years and studied the different technologies designed to prevent them from occurring. The study found that while certain technologies may be effective for different scenarios, no single technology is effective in preventing all the scenarios that lead to pediatric vehicular heatstroke, suggesting a combination of interventions is required to achieve the best prevention strategy.

Artificial intelligence chatbots are everywhere these days, from smartphone apps and customer service portals to online search engines. But what happens when these handy tools overestimate their own abilities? 

Researchers asked both human participants and four large language models (LLMs) how confident they felt in their ability to answer trivia questions, predict the outcomes of NFL games or Academy Award ceremonies, or play a Pictionary-like image identification game. Both the people and the LLMs tended to be overconfident about how they would hypothetically perform. Interestingly, they also answered questions or identified images with relatively similar success rates.
