Final answer:
Piaget's concept of centration is the tendency of preoperational children to focus on one aspect of a situation to the exclusion of other relevant details.
Step-by-step explanation:
The tendency of preoperational children to be captivated by a single aspect of a given situation to the exclusion of other relevant details exemplifies Piaget's concept of centration.
Centration is the tendency to focus on one particular piece of information when making decisions or problem-solving, and it is a characteristic of the preoperational stage of cognitive development according to Piaget. Children in this stage have not yet developed an understanding of conservation, which is the idea that even if you change the appearance of something, it is still equal in size as long as nothing has been removed or added.
For example, if you show a preoperational child two glasses filled with the same amount of water, and then pour one of them into a taller and narrower glass, the child will often say that the glass with more water in it has more liquid, because they are only focused on the height of the water and not the width of the glass.
