The concept of interdisciplinarity is introduced within its larger int
ellectual context, that of the relation between science and the humani
ties, as well as related to psychology and, in particular, the psychol
ogy of art and creativity. Empirical research on the arts and creativi
ty is in a good position to further interdisciplinarity, but I argue t
hat such studies are insufficiently reciprocal. Psychology takes more
from the arts (e.g., its materials) than it gives back (i. e., illumin
ating scholarly and artistic concerns). I argue that, if the scientifi
c psychology of art is to become fully interdisciplinary, it has to ra
ke greater account of artistic sensibilities and expertise. Suggestion
s for achieving greater reciprocity are offered. Examples from my rese
arch on old age, art, and creativity (e.g., the ''old-age style'') are
used to illustrate an interdisciplinary model that, if followed, woul
d benefit other areas of psychology (e. g., cognitive psychology) as w
ell as advance interdisciplinarity in general (i.e., by showing that q
uantitative and discursive modes of inquiry can be combined). These as
pects of interdisciplinarity, among others, are discussed in the artic
les that follow mine in this Special Issue of Creativity Research Jour
nal, along with empirical and pedagogical illustrations, and conceptua
l extensions.
