Abstract

The influence of trust on automation reliance has been examined during interaction with the automation, but little attention has been paid to individuals' initial expectation of automation reliability as it affects future reliance, especially when the cost of not relying on automation is known in advance. Additionally, whereas automation may help to improve the lives of older adults, their expectations of automation reliability have not been thoroughly considered. In this study, 16 older adults and 16 younger adults were asked about their expectation of the reliability of an automated counting aid and half were told that they would lose points for verifying the automation. Subsequent reliance on the decision aid was recorded. The results indicated that neither age nor the cost of verification appears to have an effect on reliability expectancy. Furthermore, predictions of reliability had a negative correlation to reliance. The findings suggest that individuals develop expectations of automation over the course of experience and interaction with automation.
