“…The type of error that increased under TP differed by task difficulty. In one study, it was reported that the type of error in the easy task was mainly a time‐up error and that the type of error in the hard task was mainly a processing error (Yamazaki, Karashima, & Saitoh, 2003). Our results show that the infusion pump operation in this experiment was a comparatively easy task for the experienced nurses, a slightly hard task for the inexperienced nurses, and a very hard task for the students.…”

Aim: According to a national report on incident analysis, the mental workload that exists during the i.v. medication administration process might affect nurses' visual behavior and, thus, influence the accuracy of the process. This study examined changes in the visual behavior of nurses who operated an infusion pump under the influence of time pressure and dual tasking. Methods: Ten nursing students, 13 experienced nurses, and nine inexperienced nurses, equipped with an eye tracker and instruments that measure the heart rate and breathing frequency, carried out an infusion pump operation in a simulated patient room under three mental workload conditions: without a mental workload, under time pressure, and while dual tasking. Results: Under the time pressure condition, the total visual fixation duration of the procedures was shortened. The experienced and inexperienced nurse groups could shorten the tasks in order of priority but the student group could reduce the tasks only inconsistently. Dual tasking had no influence on the total fixation duration of the procedures. However, the fixation location was influenced by the dual-tasking condition. This condition caused dispersed attention in the student and inexperienced-nurse groups, but not in the experienced-nurse group. Conclusion: Time pressure appears to cause nurses to shorten the duration of infusion pump operation and to reduce the quantity of checking. Dual tasking appears to have no influence on the total visual fixation duration but causes dispersed attention, reducing the quality of checking.

To become a physical therapist, one must attend a training school, attend various lectures, and memorize many terms, and this requires efficient memorization. Therefore, we studied the effects of two different methods, in which nonsense words were presented visually, on recall. [Participants and Methods] The participants were 15 university students. They were shown one set of 10 words for 5 minutes. In the control condition, all 10 words were constantly displayed for 5 minutes, and in the intervention condition, one word was erased every 30 seconds. After repeating this procedure with 7 sets, the number of participants who could recall all 10 words, the number of sets in which the participants could recall all 10 words, the number of words correctly answered, and the number of words recalled after 24 hours were compared between the two conditions. [Results] The number of sets in which all words were recalled was significantly lower for the intervention condition, but the number of words recalled was significantly higher. The number of words recalled at 24 hours was significantly higher for the intervention condition. [Conclusion] The results suggest that erasing words one by one is more effective for memorization of visual presentation than displaying all the words all the time.

In this study, the process of inducing mutual cooperation among workers in a remote work environment (telework) was experimentally examined. The gambling task developed by Payne was used, and subjects were not given information regarding their partners’ reputations. In addition, subjects and their partners completed the task in different rooms to avoid the effects of verbal and nonverbal communication. Subjects knew only which buttons their partners pushed, i.e., their behavior in the remote work environment. The number of experimental trials was 100. We found that cooperative behavior was induced by the 33rd trial. Although subjects did not know their partners’ reputations, cooperative behavior arose as subjects saw which buttons their partners pushed. In a control experiment, the subjects competed with a computer, and the results suggested that cooperative behavior was not induced when a human subject competed with a computer. Overall, the results suggest that an exchange of nonverbal behavioral information was necessary for inducing cooperative behavior.
