form-quality

from The Century Dictionary.

• noun In psychology, that which gives to a group of elementary mental processes a certain perceptual or ideational form, or indicates the specific group-arrangement: regarded by certain authors as a positive ideational content, appearing in consciousness together with such ideational complexes as are composed of separable elements, but referred by others to the laws of association and the selective activity of attention. The term was introduced by C. von Ehrenfels in 1890.
