Non-representational theory is the study of a specific theory focused on human geography. It is the work of Nigel Thrift ( Warwick University).   The theory is based on using social theory, conducting geographical research, and the 'embodied experience.' 
Instead of studying and representing social relationships, non-representational theory focuses upon practices – how human and nonhuman formations are enacted or performed – not simply on what is produced.  "First, it valorizes those processes that operate before … conscious, reflective thought … [and] second, it insists on the necessity of not prioritizing representations as the primary epistemological vehicles through which knowledge is extracted from the world".  Recent studies have examined a wide range of activities including dance,   musical performance,  walking,  gardening,  rave,  listening to music  and children's play. 
This is a post-structuralist theory inspired in part by the ideas of the physicist- philosopher Niels Bohr,    and thinkers such as Michel Foucault, Gilles Deleuze, Félix Guattari, Bruno Latour, Michel Serres and Karen Barad, and by phenomenonologists such as Martin Heidegger and Maurice Merleau-Ponty.  More recently it considers views from political science (including ideas about radical democracy) and anthropological discussions of the material dimensions of human life.[ citation needed] It parallels the conception of "hybrid geographies" developed by Sarah Whatmore. 
Critics have suggested that Thrift's use of the term "non-representational theory" is problematic, and that other non-representational theories could be developed. Richard G. Smith said that Baudrillard's work could be considered a "non-representational theory", for example,  which has fostered some debate.[ citation needed] In 2005, Hayden Lorimer (Glasgow University) said that the term "more-than-representational" was preferable.
