Stuart Marshall discusses the more theoretical interpretations of video art and varying levels of accessibility in light of self-referential or explorative techniques by the artists.. Because video art has a brief history, it has not been allowed an in-depth investigation in to the theoretical implications of video. Marshall discusses Lacan and Freud in this light, focussing in particular on the "imaginary", postulating that video art is in a state of imaginary regression. "It has been suggested by both artists and psychotherapists that the use of video can lead to an "authentic" awareness of the self, but its potential lies in its narrative core" (pg. 247).
