Post-humanist participatory arts-based research (PABR) ethics of care raise critical concerns for how researchers orient themselves toward their projects and participants and seek to enact research with care, reciprocity, and respect. From a literature review and five case studies of PABR, I characterize the methodologies that embody critical participatory arts-based research based in values of care, reciprocity, and respect. Further, I critique my participatory visual inquiry project from a post-humanist PABR lens and further envision the co-production of knowledge with human and non-human, emergent participants as acts of care, reciprocity, and respect. In doing so, I open my research to rhizomatic and relational understandings of inquiry that foster alternative knowledges and ontologies about doing research in a community of emergent participants while questioning the ethical limitations of their unknowing and non-consenting participation.
