As artificial intelligence increasingly serves as an active teammate in complex work environments, understanding how AI behavior influences trust and team performance is essential. This study examined the effects of AI transparency and cooperation in a three-agent (Human-Human-AI) Human–Automation Teaming task based on a cooperative disease treatment simulation. 146 participants (73 teams) were assigned to one of four conditions in a 2 (Cooperation: High vs. Low) × 2 (Transparency: High vs. Low) between-subjects design. Subjective trust, behavioral reliance, team efficiency, and win rate were assessed using surveys, gameplay behaviors, and system logs. Neither subjective trust, behavioral reliance, nor win rate differed across conditions. However, after controlling for agent processing time, teams interacting with a highly transparent agent completed turns significantly faster than teams with a low-transparency agent. These findings suggest transparency may improve coordination efficiency without affecting trust or team effectiveness in newly formed Human–AI teams.

The study investigated whether vigilance performance improves when tactile stimuli are dual-coded with visual or auditory signals, compared to unimodal conditions. Prior studies investigated visual-audio dual coding, whereas dual coding including tactile information has not been examined. One hundred participants completed a 40-min vigilance task under tactile-only, visual-only, audio-only, visual-tactile, or audio-tactile conditions. Participants pressed the spacebar when the critical stimulus (shorter duration) occurred and withheld responses when the neutral stimulus (longer duration) occurred. Results showed a vigilance decrement in all conditions, with decreases in proportion of correct detections and sensitivity, and increases in response bias, reaction time and false alarms, during the course of the vigil. Dual-coded conditions showed higher sensitivity and proportion of correct detections compared to unimodal conditions, and the audio-tactile condition yielded the best performance. These results suggest that dual coding with closely coupled (audio-tactile) modalities improves signal salience, especially in tasks requiring duration discrimination.
