Impact of AI-generated characters on visual attention and prefrontal cognitive responses across age and image type conditions: using fNIRS and eye-tracking

= 0.006). Age conditions and image type conditions significantly affected visual attention and prefrontal cognitive responses. This suggests that visual stimuli influence not only simple preference but also users' emotional response and broader cognitive processing. Furthermore, this study's integrated approach, combining an eye-tracker and fNIRS, can provide practical evidence for user experience-based AI content and interface design.
