A child is playing at the beach. She pours an equal amount of sand into both a short, fat container and a tall, thin container. When asked which container holds more sand, the child points to the tall, thin container. This response suggests that she is most likely in the stage of cognitive development.

Preoperational Stage of Cognitive Development

Explanation:

The preoperational stage of cognitive development is the stage when children start learning about the world by experiencing it, but they are not yet able to manipulate the information that they have learned. During this stage, children begin to engage in symbolic play and learn to manipulate symbols. However, they are yet to understand actual reasoning. During this stage children have difficulties thinking about more than one aspect of any situation at the same time; and they have trouble decentering in social situation just as they do in non-social contexts.

The answer is the preoperational stage of cognitive development.

Explanation:

The preoperational stage of cognitive development begins around age two and it lasts until age seven. In this stage, children think through symbols but they are not able to utilize cognitive operations.

The child's thinking in this stage is considered pre-operations. Thus, the child is not able to use logic or separate different ideas. It is said that a child's development is related to the different experiences that a child can construct about the world through the adaptation to the environment, as well as working to achieve the stage in which he or she can use logical thought.
