Abstract:

Due to both optical distortion and water turbidity, divers are usually inaccurate when they estimate distances under water. Previous studies have demonstrated that training with feedback improves judgment accuracy. The present study showed that the effect of training diminishes considerably during the nine weeks following training. A more extensive training program is recommended for diving tasks in which distance estimation is important.
