Final answer:
The stage in Piaget's theory related to logical thought about concrete events is the concrete operational stage, making Option 3 the correct answer. In this stage, children develop logical thinking abilities, understand the concept of conservation, and can perform operations like addition and subtraction.
Step-by-step explanation:
The concept in Piaget’s theory that relates to logical thought is the concrete operational stage. This is Piaget’s third stage of cognitive development, occurring from approximately 7 to 11 years of age. In this stage, children begin to think logically about concrete events. They develop a better understanding of the concept of conservation and are able to perform mathematical operations such as addition and subtraction, recognizing for instance that the former is the opposite of the latter. This stage is crucial for the development of logic in children as they make sense of the world through a more rational viewpoint.
While the concrete operational stage is associated with logical thinking about real events, the formal operational stage, which is Piaget's fourth and final stage, involves abstract and hypothetical thought. This latter stage emerges from around age 11 into adulthood and enables individuals to deal with abstract ideas and hypothetical situations, allowing for more sophisticated problem-solving and reasoning abilities. In summary, though the formal operational stage encompasses advanced abstract thinking, it is the concrete operational stage that is central to the development of logical thought about concrete, real-world scenarios. Therefore, the correct option in response to the question is Option 3: Concrete operational stage.
