“…Although this study did not investigate the effects of apologies due to metaphysical differences, we believe that a human clerk’s apology will be more effective than one from a robot clerk. A past study reported the importance of apology cost toward acceptance [ 31 ], and human clerks currently have higher social status than robot clerks.…”

“…Researchers argued that observations of conversational-style information-providing between robots are easier for people than direct interaction with a social robot. Other studies reported the effectiveness of using multiple robots in education contexts for children [ 31 , 34 ] and conversational services for the elderly [ 41 ]. These past studies described the effects of the behavior and the impression changes of the people involved by interaction with multiple robots.…”

“…To create a more acceptable apology for a robot, we focused on the number of robots that apologize. Past studies showed the effectiveness of using multiple robots in service contexts [ 31 , 32 , 34 , 40 , 41 ]. Moreover, using multiple robots simply increases the perceived cost of apologizing compared to a single robot.…”

“…Past studies reported the importance and effectiveness of apology behaviors of service robots [22][23][24][25][26][27][28][29]. However, these studies mainly focused on an apology from one robot, i.e., less focused on the effects of apologies from multiple robots, although using multiple robots could influence peoples' perceptions strongly more than using one robot [30][31][32][33][34].…”

“…In the field of human-robot interaction, several studies have investigated situations where multiple robots collaborate to provide services. Several studies reported the effectiveness of using multiple robots during interactions with people, such as rewarding [30,31] and information-providing services [32][33][34]. These studies reported that even though the amount of information is identical between multiple robots and a single robot, people prefer the former.…”

Although the capabilities of service robots are increasing, avoiding any mistakes is difficult. Therefore, strategies for mitigating mistakes, such as apology behavior designs, are essential for service robots. Past studies reported that costly apology is perceived as more sincere than non-costly ones and more acceptable. To increase the apology cost in robot service situations, we thought that using multiple robots would increase the perceived costs in the of financial, physical, and time costs. Therefore, we focused on the number of robots who apologize for their mistakes as well as their individual, specific roles and behaviors during such apologies. We investigated the differences in perceived impressions toward apologies from two robots (the main robot that makes a mistake and apologizes and a sub-robot that also apologizes) and an apology from just one robot (only the main robot) through a web survey with 168 valid participants. The experiment results showed that the participants significantly preferred and positively evaluated apologies from two robots more than one robot in the context of forgiveness, negative word-of-mouth, trust, and intention to use. We also conducted another web survey with 430 valid participants to investigate the effects of different roles for the sub-robot: apologize-only, cleaning-up-only, and both actions. The experimental results showed that the participants significantly preferred and positively evaluated both actions in the context of forgiveness and reliable/competent perspectives.

This study experimentally compared the effects of encouragement with polite/ impolite attitudes from a robot in a monotonous task from three viewpoints: performance, mood, and propagation. Experiment I investigated encouragement effects on performance and mood. The participants did a monotonous task during which a robot continuously provided polite, neutral, or impolite encouragement. Our experiment results showed that polite and impolite encouragement significantly improved performance more than neutral comments, although there was no significant difference between polite and impolite encouragement. In addition, impolite encouragement caused significantly more negative moods than polite encouragement. Experiment II determined whether the robot's encouragement influenced the participants' encouragement styles. The participants behaved similarly to the robot in Experiment I, i.e., they selected polite, neutral, and impolite encouragements by observing the progress of a monotonous task by a dummy participant. The experiment results, which showed that the robot's encouragement significantly influenced the participants' encouragement styles, suggest that polite encouragement is more advantageous than impolite encouragement.
