A child who cannot conserve will assume the taller glass has more liquid than the shorter glass. Piaget’s other famous task to test for the conservation of liquid involves showing a child two beakers, A1 and A2, which are identical and which, the child agrees, contain the same amount of colored liquid.
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 ...
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 ...
Piagetian tests are well known and practiced to test for concrete operations. The most prevalent tests are those for conservation. There are some important aspects that the experimenter must take into account when performing experiments with these children. One example of an experiment for testing conservation is the water level task.
Special methods are used in the psychological study of infants. 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.
This is an example of horizontal décalage because children were able to solve certain conservation tasks but not others despite their similarities. According to the neural network approach, as a child's prefrontal cortex develops, he or she is better able to maintain their knowledge "rules" and apply problem solving techniques across different ...
These results have since been replicated in a number of studies, and most subsequent interest in the water-level task has been concerned not with the study of child development but rather with accounting for the adults and adolescents that fail the test, and the apparent difference in success rates between the sexes.

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.
