Ethnic differences in the relative effectiveness of incentives

An experiment was performed to test the hypothesis that the
performance of B.C. Indian children for non-material incentives
would be inferior to their performance on the same task for material incentives. The reverse was expected to be true of middleclass
white Canadian children. Working-class white children were
expected to be intermediate.
Sixty-six male Ss from 6 to 13 years were given fifty trials
on a discrimination task. They were reinforced either by candy
or by a light flash. Middle-class Ss were significantly superior
to Indian and working-class Ss under non-material but not under
material conditions. There was, however, no significant difference
between Indians and working-class whites.
Other measures included TAT stories scored, for n Achievement
and an immediate-delayed reward choice. Each of these discriminated
middle-class white Ss from the other two groups, but did not
discriminate between Indian and working-class children. Middleclass
Ss were much more likely to show achievement imagery and to
choose a larger, delayed reward.
Reservations about making generalizations from the results
Of this sample were discussed; refinements in the procedures were
proposed; and behavioral contrasts between the three subcultural
groups were described with the view of presenting suggestions for
further research in this area. / Arts, Faculty of / Psychology, Department of / Graduate
