effectance

For example, Jerome Frank’s (1968; Frank & Frank, 1991) work on the concept of “mastery” and his discussion of the weakened morale characteristic of psychiatric patients, and Robert White’s (1963) postulation of “effectance” and “competance” as independent ego energies concerned with “adaptation and with the governing of behavior by reality”(p. 24) both identify a similar theme.
