How Human Likeness, Gender and Ethnicity affect Elders’Acceptance of Assistive Robots

Abstract

The present study investigates the extent to which robots’ 1) degree of human likeness, 2) gender and 3) ethnicity affect elders’ attitude towards using robots as healthcare assistants. To this aim 2 groups of 45 seniors, aged 65 + years, were asked to watch video clips showing three speaking female and male robots, respectively. Each set of stimuli consisted in 2 androids, one with Caucasian and one with Asian aspect, and 1 humanoid robot. After each video clip elders were asked to assess, through the Robot Acceptance Questionnaire (RAQ) their willingness to interact with them, as well as robots’ Pragmatic, Hedonic and Attractive qualities. Through this investigation it was found that male seniors were more proactive than female ones in their attitude toward robots showing more willingness to interact with them and attributing more positive scores to robots’ qualities. It was also observed that androids were clearly more preferred than humanoid robots no matter their gender. Finally, seniors’ preferences were for female android robots with Asian traits and male android with Caucasian traits suggesting that both gender and ethnical features are intermingled in defining robot’s appearance that generate seniors’ acceptance.
