Delegation of a task to a partner in cooperation with a human partner and with a system partner

AbstractThis study investigated the delegation of tasks to a partner in cooperation with a human partner and with an automation system as a system partner. In the experiment, a line-tracing task was used, in which the performance in the task of the participants and their partners was dynamically altered at multiple levels. The participants were informed that their task partners were human (human condition) or automation system (system condition). However, in reality, all participants performed their task with an automation system. The results showed that a relationship between subjective trust in the partner and the percentage of the task delegated to the partner was found only in the system condition but not in the human condition. Moreover, sensitivity to change in the task performance of the participants and their partners was higher, and the suitability of task delegation was greater in the system condition than in the human condition. These results were discussed based on the previous studies.
