The authors used person-environment fit theory and
polynomial regression analyses to investigate data taken
from 833 respondents of different occupations. Intrinsic
and extrinsic rewards, and the value individuals placed
on those rewards, predicted three dependent variables
positively, but not necessarily via similar (linear,
curvilinear, interactive) forms. Most important,
addressing the historic controversy over whether
extrinsic rewards undermine intrinsic motivation,
extrinsic rewards showed no negative relationships (from
among an array of relevant direct and interactive tests)
with attributions of intrinsic motivation, perceived
personal control, or job satisfaction. pdf
