Patterns of nonverbal behavior among adolescents responding to a formal reasoning task

This study investigated nonverbal behavior patterns of 11 adolescents who responded to the Inhelder-Piaget (1958) balance task, which provides an assessment of proportional reasoning and was the first study of how students behave while being assessed for formal reasoning ability. Interdependency among the precisely defined categories of behavior was found, even when the categories were collapsed on a conceptual basis. Consequences of this categorical interdependency were discussed.
