peggys parents are amazed at how much their daughter has changed. for one thing, over the past year she became interested in doing chemistry experiments. peggy predicts what will happen when she combines two chemicals together and then observes the results to see whether her hypothesis was correct. peggy is most likely in the ______ stage of cognitive development.
formal operational
sensorimotor
preoperational
concrete operational

Explanation:

1. For the first question:

• Carla engages in mental - stimulating activities which can be beneficial for cognitive health.
• Charles walks regularly, which is good for physical health.
• Cindy has a long - term regular exercise routine, promoting overall health.
• Carson's habits of squinting (which may strain eyes) and listening to loud music (which can damage hearing) are negative for physical health.

1. For the second question:

• In the formal operational stage of Piaget's cognitive development theory, children can think abstractly, form hypotheses, and conduct experiments to test them. Peggy's behavior of predicting and testing hypotheses in chemistry experiments indicates she is in the formal operational stage. The sensorimotor stage is mainly about learning through senses and actions in infancy, the pre - operational stage is characterized by egocentrism and lack of logical thinking in early childhood, and the concrete operational stage involves logical thinking about concrete events.

Answer:

1. Carson
2. formal operational
