The effects of person and machine characteristics on operator use and monitoring of an automated system.

摘要

Organizations are increasingly automating tasks that were once performed solely by humans. However, in many cases automation has failed to increase organizational productivity. This study posits that human operators of automated technology make errors at two decision points: the decision of whether to use the automated system and the decision of whether to monitor the automated system for errors. The present research investigates the factors influencing these two decisions. A sample of 253 undergraduates participated in a computer-based simulation of an airport security screening task. While visually searching for guns and knives in X-ray images of luggage, participants had the option of using an automatic screener. Results indicated positive and significant effects of trust and affect toward the automated system on use and monitoring of this automatic screener. The effects of self-efficacy, conscientiousness, extraversion, desire to decrease cognitive load, and the interaction between trust and self-efficacy were non-significant.
