INTENTIONAL COMMUNICATION IN THE TREE DRAWING TEST
Konttinen, R. & Karila, A. Intentional communication in the tree drawing test. Scand. J. Psychol., 1969, 10, 129–136—One way in which relationships between drawing variables and personality traits may be conceived is by interpreting the drawing as intentional communication. Some implications of this proposition were tested. Five formal variables of tree drawings were studied: angularity, size, form level, shading, and pressure. Only angularity can unambiguously be given a communication interpretation; but the other variables, too, may perhaps be used for intentional communication.
