In the study, older adults who recalled more robots portrayed in films had lower anxiety toward robots than seniors who remembered fewer robot portrayals, said S Shyam Sundar from Pennsylvania State University in the US.
Researchers conducted a survey of 379 older adults-ages 60 to 86. They were asked to list up to three films they remembered watching that featured a robot.
Of the 379 people surveyed, 160 remembered one robot film, 129 recalled two and 90 remembered three. The participants were then asked about their opinions on and feelings toward the robots that were recalled.
Finding ways to ease anxiety about robot adoption could help them accept robots as caregivers, they said.
"Increasingly, people are talking about smart homes and health care facilities and the roles robots could play to help the aging process. Robots could provide everything from simple reminders - when to take pills, for example - to fetching water and food for people with limited mobility," said Sundar.
The most recalled robots included robots from Bicentennial Man, Forbidden Planet, I, Robot, Lost In Space, Star Wars, The Terminator, Transformers and Wall-E.
"One of the most surprising results in general was the more robot portrayals they could recall, regardless of the robot's characteristics, actually led to more positive attitudes on robots and eventually more positive intentions to use a robot," said T Franklin Waddell from Pennsylvania State University.
"So, it seems like the more media portrayals they can recall, the more likely their attitudes would be positive toward robots, rather than negative," Waddell said.
An example of a portrayal of a friendly helper robot might include C3PO from Star Wars, while the robot from Terminator may be an example of a threatening one, researchers said.
"The more sympathetic the participants felt toward the robot - for example, the robot in Wall-E - the more positive they felt toward robots. So, Hollywood portrayal of sympathy makes a difference and Hollywood portrayal of humanness makes a difference. Both reduce anxiety toward robots," said Sundar.
Robot designers may want to incorporate features that remind older adults of robots in the media, researchers said.
The findings were presented at the Human-Robot Interaction conference.
