She used Piaget’s conservation tasks and two combinational tasks. [2] This study was conducted by giving 500 Chinese and European boys age ten to thirteen the Piagetian tasks of conservation of weight, volume, and space, along with Raven’s Progressive Matrices task and Piaget’s factorial problem. [ 2 ]
In many cases, training tasks are successful in teaching non-conserving children to correctly complete conservation tasks. [5] Children as young as four years of age can be trained to conserve using operant training; this involves repeating conservation tasks and reinforcing correct responses while correcting incorrect responses. [7]
He believed that children of different ages made different mistakes because of the "quality rather than quantity" of their intelligence. [4] Piaget proposed four stages to describe the development process of children: sensorimotor stage, pre-operational stage, concrete operational stage, and formal operational stage. [5]
The children were asked to hide another doll, a “boy” doll, away from both policemen's views. The results showed that among the sample of children ranging from ages 3.5-5, 90% gave correct answers. When the stakes were raised and additional walls and policeman dolls were added, 90% of four-year-olds were still able to pass the task. [7]
Other conservation tasks include conservation of number, substance, weight, volume, and length. Perhaps the most famous task indicative of centration is the conservation of liquids task. In one version, [3] the child is shown two glasses, A1 and A2, that are filled to the same height. The child is asked if the two glasses contain the same ...
Piaget's test for Conservation. One of the many experiments used for children. Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire ...
Jean Piaget identifies several mental operations of the concrete operational stage of cognitive development: [3] Mental operations according to Jean Piaget. Seriation—the ability to sort objects in an order according to size, shape, or any other characteristic. For example, if given different-shaded objects they may make a color gradient.
The results revealed that the "hidden length" seriation task and the weight seriation task were much more difficult for the children than were the normal seriation tasks, thereby supporting the notion of horizontal décalage. [3] While the children were able to successfully complete certain seriation tasks, they were unable to complete others.
