In 1919, while working at the Alfred Binet Laboratory School in Paris, Piaget "was intrigued by the fact that children of different ages made different kinds of mistakes while solving problems". [2] His experience and observations at the Alfred Binet Laboratory were the beginnings of his theory of cognitive development. [3]
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] The effects of training on one conservation task (such as conservation of liquid) often transfer to other conservation tasks. [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]
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.
Jean Piaget was a major force establishing this field, forming his "theory of cognitive development". Piaget proposed four stages of cognitive development: the sensorimotor, preoperational, concrete operational, and formal operational period. [2] Many of Piaget's theoretical claims have since fallen out of favor.
As an example, consider that for children in the sensorimotor stage, teachers should try to provide a rich and stimulating environment with ample objects to play with. Then with children in the concrete operational stage, learning activities should involve problems of classification, ordering, location, conservation using concrete objects. [ 1 ]
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 ...
Smith and Thelen [2] used a dynamic systems approach to the A-not-B task. They found that various components of the activity (strength of memory trace, salience of targets, waiting time, stance) combine in the "B"-trial (where the object is hidden in the "B" location rather than "A") so the child either correctly or incorrectly searches for the ...
