“…Additional research (see a review by Condry, 1977) has demonstrated this effect with nursery school children (Greene & Lepper, 1974;Lepper, Greene, & Nisbett, 1973;Ross, 1975), elementary school children (Maehr & Stallings, 1972), high school students (Kruglanski, Friedman, & Zeevi, 1971), and college students (Benware & Deci, 1975;Deci, 1972aDeci, , 1972bDeci, Benware, & Landry, 1974;Deci, Cascio, & Krusell, 1975). Calder and Staw (1975), Kruglanski et al (1975), and Pritchard, Campbell, and Campbell (1977) also demonstrated that attitudinal measures of intrinsic motivation (i.e., ratings of interest and liking for a task) could be used with similar results.…”
