Age Difference in Perceived Ease of Use, Curiosity, and Implicit Negative Attitude toward Robots

Understanding older adults’ attitudes toward robots has become increasingly important as robots have been introduced in various settings, such as retirement homes. We investigated whether there are age differences in both implicit and explicit attitudes toward robots after interacting with an assistive robot. Twenty-four younger and 24 older adults were recruited. Explicit attitudes were measured by self-reported questionnaires both before and after interacting with the robot. State curiosity toward robots was also measured as a momentary form of explicit attitude. Implicit attitude was measured via an implicit association test. Our results showed that (1) both older and younger adults had more positive explicit attitudes toward robots after interaction; (2) older adults had lower state curiosity than younger adults, however, their state curiosity would be up to the same level as younger adults when they perceived the robot with higher levels of personal association; and (3) the implicit association between robots and negative words was stronger for older adults than younger adults, suggesting that older adults had more implicit negative attitude toward robots. The results suggest that, despite older adults’ relatively more negative implicit attitude toward robots, personally relevant positive experiences could help improve their explicit attitudes toward robots.
