DEVELOPMENT OF CONCRETE OPERATIONS AMONG HAUSA

To assess the development of concrete operations among the Hausa, seven conservation tasks were individually administered to 449 children between the ages of 5 and 13 years. A 50% rate of conservation responses was achieved on most tests by age 12. Schooled children had significantly higher scores on only a few tasks; schooling did not seem to be a major factor in accelerating the attainment of concrete operations. There were also social class and urbanization effects on several tasks. As a combined test, the Piaget battery seems to be closely related to several intelligence test subtests, particularly those with reasoning components. In addition, the test results of three Piagetian tasks were analyzed to identify the underlying reasoning processes. © 1978, Sage Publications. All rights reserved.
