## Key findings

- Combining qualitative and quantitative methods can capture subtle dimensions of body perception.
- A three-stage integration model supports transparency and multidisciplinary collaboration.
- Qualitative tools can improve the reporting of exploratory practices in quantitative research.

## Abstract

Experimental psychology and cognitive neuroscience have attempted to understand the underlying functioning of one's body experience. This has resulted in standardized methods involving multisensory manipulations and physiological, behavioral, and subjective measures. These approaches contribute to the important goal of creating a cumulative and reproducible science. However, they may sometimes lead to some well‐known pitfalls; most notably, construct ambiguity, measure dissociations, and loss of nuance. In this argumentative work, we propose that combining qualitative methods employed in design research centred on body experiences, together with quantitative approaches from psychology and cognitive neuroscience, can yield a richer account without compromising quantitative rigor. This integration of quantitative and qualitative methods, we argue, may be particularly valuable when dealing with one's body perception. Without pretending to fundamentally solve methodological discrepancies between qualitative and quantitative approaches, we propose a conciliatory take. We propose a three‐staged integration model that may be mapped to three common steps of the research inquiry: the experimental design, data collection, and data analysis. We further provide a synthesis of qualitative tools and methods to support the explicit reporting of exploratory practices that often remain informal in quantitative research. Our suggested mixed methods approach aims to account for individual differences, produce more nuanced insights, increase transparency, foster multidisciplinarity, and potentially speed progress in some aspects of the research program.

This study contributes to advancing body perception research by complementing existing psychophysiological and behavioral quantitative approaches with qualitative methods from design research. Given the uniqueness of body perception compared to other aspects of sensory experience, a mixed‐methods framework is essential to capture subtle dimensions of experience that may be overlooked by conventional protocols. We offer a pragmatic three‐step approach and a set of tools set to enhance transparency, methodological rigor, and experimental efficiency while fostering multidisciplinarity.
