Answer 1

Tammy lacks the concept of conservation, which is the understanding that certain properties of objects remain the same despite changes in form.

Step-by-step explanation:

Five-year-old Tammy mistakenly believes that her short, wide glass contains less soda than her brother's tall, narrow glass, despite both containing the same amount. This illustrates that Tammy lacks the concept of conservation. Conservation refers to the understanding that certain properties of objects, such as volume, mass, and number, remain the same despite changes in the form or arrangement of the objects. Tammy's difficulty in realizing that the soda in the glasses is equal indicates that she has not yet developed this concept, a cognitive milestone that children typically reach in the concrete operational stage of cognitive development, according to theorist Jean Piaget.
