Rankanen, The Visible Spectrum - Participants' experiences of the process and impacts of art therapy

The Visible Spectrum explores participants' experiences of the art therapy process and its impacts in the contexts of adult education and psychotherapy. The spectrum of light is invisible, unless it meets facets of glass, which break it into observable colours. Similarly, internal experiences are largely invisible for others, until they become expressed and communicated. By utilising the metaphor of triangular glass pyramid this research illuminates the spectrum of art therapy participants' unique experiences and makes explicit the multiple theoretical angles through which the research subject is explored.
