This study investigated how wait time influences trust in and reliance on a robot. Experiment 1 was conducted as an online experiment manipulating the wait time for the task partner's action from 1 to 20 seconds and the anthropomorphism of the partner. As a result, the anthropomorphism influenced trust in the partner and did not influence reliance on the partner. However, the wait time negatively influenced trust in and reliance on the partner. Moreover, a mediation effect of trust from the wait time on reliance on the partner was confirmed. Experiment 2 was conducted to confirm the effects of wait time on trust and reliance in a human-robot face-to-face situation. As a result, the same effects of wait time found in Experiment 1 were confirmed. This study revealed that wait time is a strong and controllable factor that influences trust in and reliance on a robot.
翻译：这项研究调查了等待时间如何影响对机器人的信任和依赖。实验1是一个在线实验,在1至20秒的时间里操纵任务伙伴行动的等待时间和伙伴的人类形态。结果,人类形态主义影响对伙伴的信任,而没有影响对伙伴的依赖。然而,等待时间对伙伴的信任和依赖产生了负面影响。此外,还证实了从等待时间开始对伙伴的依赖所产生的调解作用。实验2是为了确认等待时间对信任和对人机器人面对面依赖的影响。结果,证实了实验1中发现的等待时间的同样影响。这项研究表明,等待时间是影响对机器人信任和依赖的强大和可控制的因素。
