摘要
To explore the effects of different types of interference on nurses' working memory, and the role of attention control.A repeated measures design.A single-factor, four-level within-subjects design was adopted. Thirty-one nurses completed a delay-recognition task with four blocks in September 2020: Interrupting Stimulus (stimuli requiring attention), Distracting Stimulus (stimuli to-be-ignored), No Interference and Passively View. Behavioural responses of the participants and EEG data were recorded. MATLAB 21b and EEGLAB 21b were used for electroencephalogram data preprocessing and data extraction.Firstly, when nursing information system was used as task material, the accuracy rate and false alarm rate of primary tasks under interruption condition was statistically significantly different with that of distraction and no interference condition. There is a statistically significant difference in electroencephalogram measurement between correct and wrong response under interruption. Secondly, the role of attention control was different under interruption and distraction. There was a statistically significant positive correlation between the average amplitude distraction attention control index and task accuracy, and statistically significant negative correlation between the latency interruption attention control index and the accuracy of working memory task.There were different effects of interruptions and distractions on nurses' working memory and the role of attention control were also different. Measures can be designed according to these results to reduce the negative impact of interference on nurses, so as to improve work efficiency and reduce patient risk.This study has implications for clinical nursing during human-computer interaction. Resumption of the speed of the target information after an interruption affected task performance. Therefore, interventions should be designed to reduce the time needed for nurses to extract task information after an interruption, such as providing key clues in the information system interface.Registered nurses participated in the study as subjects.
