In Prosthetic Memories, Hyaesin Yoon examines the entanglements of humans, animals, and technologies across South Korea and the United States at the turn of the twenty-first century. Interrogating a variety of body-technology interfaces, Yoon outlines an emergent mode of prosthetic memory in which human memory is extended into both machines and animals. Prosthetic memory overflows and provides an alternative to familiar human perception, Western scientific reason, and other senses of knowledge in ways that can foster networks of solidarity, care, and empathy between human and nonhuman subjects. Among other sites and subjects, Yoon examines tongue surgery to correct English pronunciation in Korea, Asian American poetry that engages the human-machine divide, transnational dog cloning, and stem cell research, each of which activates potent postcolonial feminist mnemonics and alliances. In so doing, Yoon narrates the countermemories of racialized, gendered, diasporic, queer, and marginalized human and nonhuman others that work against the violent and isolating biopolitical and neoliberal forces in contemporary society.
