theory-formation occur. Part of their investigative process, children often ask questions, frequently posing "Why?" to adults, not seeking a technical and scientific explanation but instead seeking to investigate the relation of the concept in question to themselves, as part of their egocentric view. In a study where Mexican-American mothers were interviewed over a two-week period about the types of questions their preschool children ask, researchers discovered that the children asked their parents more about biology and social behaviors rather than nonliving objects and artifacts. In their questions, the children were mostly ambiguous, unclear if they desired an explanation of purpose or cause. Although parents will usually answer with a causal explanation, some children found the answers and explanations inadequate for their understanding, and as a result, they begin to create their own theories, particularly evident in children's understanding of religion. This theory also plays a part in Vygotsky's social learning theory, also called modeling. Vygotsky claims that humans, as social beings, learn and develop by observing others' behavior and imitating them. In this process of social learning, prior to imitation, children will first post inquiries and investigate why adults act and behave in a particular way. Afterwards, if the adult succeeds at the task, the child will likely copy the adult, but if the adult fails, the child will choose not to follow the example. Comparison with other theories Theory of mind (ToM) Theory-theory is closely related to theory of mind (ToM), which concerns mental states of people, but differs from ToM in that the full scope of theory-theory also concerns mechanical devices or other objects, beyond just thinking about people and their viewpoints. Simulation theory In the scientific debate in mind reading, theory-theory is often contrasted with simulation theory, an alternative theory which suggests simulation or cognitive empathy is integral to our understanding of others.
