title: Relationships among different stages of Piagetian tasks and spatial relations in adolescents.
abstract: High school students aged 15 through 19 years (N = 116) were administered three Piagetian type tasks (conservation of weight, paper and pencil tests of concrete-operational reasoning and formal-operational reasoning) and a measure of spatial relations (the Revised Minnesota Paper Form Board Test). While a path analysis showed there were logically expected relationships among the tasks, neither sex differences nor age differences were found on any of the measures.
