Abstract
Introduction: While robot-assisted technologies are increasingly used in clinical settings, little is known about how non-visual design elements shape perceived trustworthiness across user characteristics. This study investigated how features such as name and voice influence trust in a tangible neurofeedback companion, and whether these effects vary across individual differences in cognitive functioning, gender, and generation. Methods: Participants completed an online questionnaire (N = 743) in Qualtrics in which they rated the trust for four robot voices (female, robotic, childlike, male) and four names (Sunni, Tully, Nova, Juno). A repeated-measures design was employed for both name and voice ratings. Trust in names was compared across gender and generational cohorts, while ratings for voices were analyzed across self-reported executive and attentional functioning, gender, and generation. Results: Trust ratings differed significantly across names, F (2.71, 1672.96) = 10.23, p < .001, with competent sounding names (Nova, Juno) rated higher than the ones eliciting warmth (Sunni, Tully). Voice also significantly influenced trust, F (1.78, 1062.70) = 13.34, p < .001, and trust varied more across user profiles as shown by a significant interaction between voice, gender and attention complaints (p = .039). The male and the female voices were preferred over the robotic and childlike ones. Discussion: These findings highlight the importance of personalized design in a tangible neurofeedback companion as trust emerges from the interplay between design features and user characteristics. Future research should explore how these preferences evolve during face-to-face embodied interactions and long-time engagement.
