- | A common criticism of Piaget's theory lies on the fact that nor him or coworkers didn't leave an instrument for diagnosing child's current stage of cognitive development. Still, as a border between preoperational period and operational period Piaget suggested **conservation experiments**. For example, two equal glasses filled with liquid are presented to a child, after which liquid out of one glass is poured into a third, more narrow glass. The child is then asked which glass holds more liquid. Only a child in the concrete- or formal-operational period should realize both glasses hold equal amount of liquid. According to Piaget's theory, these stage differences cannot be overcome using any kind of training. | + | A common criticism of Piaget's theory lies on the fact that nor him or coworkers didn't leave an instrument for diagnosing child's current stage of cognitive development. |
