Kinesthetic Properties of Response Scales Yield Different Judgments.

This article investigates how the kinesthetic properties—the physical movements required by an interface—affect consumer responses on digital scales, specifically comparing slider scales and radio-button scales. Across six studies involving over 22,000 participants, the research finds that dragging a slider leads respondents to provide answers closer to the scale's starting point because the dragging motion directs sequential attention to earlier options, influencing choice. This effect reverses when the slider starts on the right side, and it persists even with nominal (non-ordered) response options, indicating that the physical interaction, rather than perceived magnitude or visual differences, drives the effect. Eye-tracking data confirm that slider users focus more on earlier options, and response-time analyses show they engage with the scale earlier in the judgment process than radio-button users. These findings highlight the importance of considering response kinesthetics in survey design, as they can subtly bias judgments and have implications for marketing, research methodology, and digital interface design.
