Administered Heimberg's Future Time Perspective Inventory, a life satisfaction scale, an events test, and an incomplete sentences test to a total of 168 females in 2 age groups (9-11 and 12-15 yr.). As predicted, (a) individual cognitive perspective (time over which future images are projected) was negatively correlated with life satisfaction for children but positively correlated for adolescents, and (b) cognitive-motivational future time perspective increased with age and was positively correlated with life satisfaction for both groups. Contrary to expectations, length of cognitive perspective decreased over age levels. (33 ref.) (PsycINFO Database Record (c) 2016 APA, all rights reserved)
