Verified step by step guidance

1. Identify the developmental stage of the child in question, which is the preschool age (approximately 3 to 5 years old).
2. Recall key cognitive characteristics of preschoolers based on developmental psychology theories, especially Piaget's stages of cognitive development.
3. Understand that preschoolers are typically in the Preoperational Stage, where they exhibit egocentric thinking—meaning they have difficulty seeing perspectives other than their own.
4. Recognize that abstract reasoning about hypothetical situations and understanding complex algebraic equations are abilities that develop much later, typically in adolescence or later childhood.
5. Conclude that the behavior most likely displayed by a preschooler is egocentric thinking, where they believe others see the world exactly as they do.
