Sally hides her marble in a basket, then leaves the room. Anne moves the marble to a box while Sally is away. When Sally returns, where will she look for her marble, and why does the correct answer demonstrate theory of mind?
AIn the box — because the marble is actually there, and Sally will see it
BIn the basket — because Sally has a false belief about where the marble is, and theory of mind requires tracking beliefs that differ from reality
CRandomly — because Sally has no information about where the marble is
DIn the basket — because Sally remembers putting it there, and memory is the same as belief
Sally will look in the basket because that is where she believes the marble to be — she did not witness Anne moving it. The key is that her belief is false (the marble is actually in the box), and correctly predicting her behavior requires attributing to her a mental state (belief) that differs from reality. Children who fail this task answer 'in the box' — tracking the objective fact rather than Sally's perspective. Passing the task at around age four demonstrates the developmental achievement of attributing false beliefs, the hallmark of theory of mind.
Question 2 Multiple Choice
According to simulation theory, how do we primarily understand what another person is thinking or feeling?
AWe apply a body of folk-psychological generalizations about how beliefs and desires cause behavior, much as a scientist applies a model to data
BWe use our own cognitive machinery 'offline' — imaginatively placing ourselves in the other's situation to generate predictions about their mental states
CWe directly perceive others' emotions through empathic resonance, without any inference or simulation
DWe consult our prior knowledge of that specific individual's history and behavioral patterns
Simulation theory holds that we understand others by running a kind of mental simulation: we take the other's presumed inputs, feed them into our own cognitive systems (decision-making, emotional responses, reasoning), and read off the output as a prediction of what they will think or do. This is a first-person, imaginative process — using our own minds as the model. Option A describes theory-theory, which uses a third-person theoretical framework of folk-psychological generalizations. Option C describes a naïve empathy view that neither major account endorses as their primary mechanism.
Question 3 True / False
The false-belief task (Sally-Anne) is used to test whether children can attribute to another person a belief that differs from reality.
TTrue
FFalse
Answer: True
Correct. The false-belief task specifically probes whether a child understands that another agent can hold a belief that is false — that is, that differs from what the child knows to be true of the world. Children reliably pass this test around age four. The task is powerful because correctly predicting where Sally will look requires tracking Sally's mental state (her belief about the marble's location) rather than tracking the objective state of the world. This is what makes it a diagnostic for theory of mind as a developmental achievement.
Question 4 True / False
Theory-theory holds that we understand other minds primarily by imaginatively placing ourselves in others' situations and simulating what we would think or do.
TTrue
FFalse
Answer: False
This describes simulation theory, not theory-theory. Theory-theory holds that we understand others by applying a tacit folk-psychological theory — a body of generalizations like 'if someone wants X and believes Y will get X, they will try to do Y' — to observed behavior. This is a third-person, inferential process, analogous to how a scientist applies a model to data. Simulation theory is the account that invokes imaginative first-person perspective-taking. Confusing the two reverses their central distinction.
Question 5 Short Answer
What is the key difference between theory-theory and simulation theory in how they explain our ability to understand other minds?
Think about your answer, then reveal below.
Model answer: Theory-theory holds that we understand others by applying an implicit folk-psychological theory — a set of generalizations about how beliefs, desires, and intentions cause behavior — in a third-person, inferential way, analogous to a scientist applying a model to data. Simulation theory holds that we understand others by using our own cognitive machinery 'offline': we imaginatively take the other's perspective, feed their presumed inputs into our own decision-making and emotional systems, and read off the output as a prediction. Theory-theory is theoretical and third-person; simulation theory is imaginative and first-person.
The debate between theory-theory and simulation theory is about the fundamental mechanism of social cognition. Theory-theory says understanding others is a theoretical achievement — mastering folk-psychological generalizations and applying them inferentially. Simulation theory says understanding others is an imaginative achievement — using your own mind as a model for the other's. The distinction matters empirically: if simulation is right, understanding others depends on the capacity for perspective-taking; if theory-theory is right, it depends on mastering causal generalizations. Hybrid views and interaction theory (direct embodied engagement) complicate both accounts.
