This study investigates crossmodal fear generalization, testing whether conditioned fear spreads between different sensory modalities. Participants in the unimodal group were presented with visual stimuli--images of a sparrow (CS+) and a laptop (CS-)--while the crossmodal group received auditory stimuli--sparrow calls (CS+) and keyboard typing…

Artificial intelligence (AI) driven chatbots provide instant feedback to support learning. Yet, the impacts of different feedback types on behavior and brain activation remain underexplored. We investigated how metacognitive, affective, and neutral feedback from an educational chatbot affected learning outcomes and brain activity using functional…

Virtual reality (VR) simulator has emerged as a laparoscopic surgical skill training tool that needs validation using brain--behavior analysis. Therefore, brain network and skilled behavior relationship were evaluated using functional near-infrared spectroscopy (fNIRS) from seven experienced right-handed surgeons and six right-handed medical…
