The Effect Of Differing Degrees Of Automation And Reliability On Simulated Luggage Screening Performance, Molly M. Liechty
The Effect Of Differing Degrees Of Automation And Reliability On Simulated Luggage Screening Performance, Molly M. Liechty
Psychology Theses & Dissertations
The present work examined the effects of two types of decision support systems in a simulated luggage screening task: An input aid and an output aid. An input aid supports an operator’s information gathering. An output aid supports decision making and action selection. A Time-Accuracy Function (TAF) analysis was applied to isolate processing time from performance asymptote, which conventional performance measures such as sensitivity and response time do not distinguish one from the other. Sixty participants performed a luggage screening task unaided (manual condition), with the assistance of an input aid (spatial aid), and with the assistance of an output …

When receiving assistance from an automated aid, human operators do not necessarily perform better than without the automated aid. The current work explored the impact of integrating the automated aid with the task information in low prevalence conditions. Specifically, this work compares displays where the automated aid was integrated with task information in general or with more meaningful task information. Subjects performed a speeded judgment task with the assistance of an automated aid, varying in display type, difficulty, and prevalence. Results indicated that there was no effect of display type or prevalence on human temporal performance, and that the effect …
