Sketch素描.Sketching is a monochrome drawing that uses lines to depict the light and shade of objects with materials such as charcoal, pencils, or pens. Monochrome watercolor and monochrome oil paintings can also be considered sketches;traditional Chinese fineline paintings and ink wash paintings can also be called sketches. Usually, sketching refers to pencil and charcoal drawings.展开更多

They have been used as adjunctive therapies for a range of mental health conditions. Significant numbers of returning military personnel experience post-traumatic stress disorder(PTSD), and discontinuation of care is a concern. Using drawing-based art therapy as an adjuvant to classical therapies may provide a benefit for such military patients.展开更多
