Document Summary
Attainments of the concrete operational stage: concrete operational stage: extends from ~7-11 years; thought is more logical, flexible, and organized, conservation. Operations: mental actions that obey logical rules; evidence is found in passing conservation tasks. Decentration: focusing on several aspects of a problem and relating them, rather than centering on just one. Reversibility: the capacity to think through a series of steps and then mentally reverse direction, returning to the starting point: classification. They are more aware of classification hierarchies and can focus on relations between a general category and two specific categories at the same time (3 cat. total) Children are better able to inhibit their habitual strategy of perceptually comparing the two specific categories. Enhanced classification skills evident in collections: seriation. Seriation: the ability to order items along a quantitative dimension, such as length or weight. 6-7 year olds create a series efficiently. 7-8 years can complete transitive inference easily: spatial reasoning.
