  • Number of classes: 2

  • Class labels: Target, NonTarget

  • Trial duration: 3.0 s

  • Study design: Participants drove a virtual racing car using steering wheel and gas/brake pedals, tightly following a computer-controlled lead vehicle at 100 km/h. The lead vehicle occasionally decelerated abruptly (20-40s inter-stimulus-interval) to 60-80 km/h, requiring immediate emergency braking. Three blocks of 45 min each with 10-15 min rest between blocks.

  • Feedback type: visual (colored circle indicating distance: green <20m, yellow otherwise; brakelight flashing)

  • Stimulus type: emergency_braking_scenario

  • Training/test split: True

  • Instructions: Drive a virtual racing car using steering wheel and gas/brake pedals, tightly follow the lead vehicle within 20m at 100 km/h. Perform immediate emergency braking when the lead vehicle decelerates abruptly to avoid a crash.

  • Stimulus presentation: isi_range=20-40 seconds, deceleration_range=60-80 km/h, brakelight=flashing, oncoming_traffic=present, sharp_curves=present
