A motivational attitude toward an outcome. Attributing a desire is distinct from establishing what an agent believes about how the outcome can be achieved.
A state directed toward bringing about an action or outcome. Inferring an intended goal from behaviour need not imply representing every belief or reason of the agent.
A state with representational content taken to be true. Attributing another person’s belief requires distinguishing its content from one’s own knowledge of the actual situation.
A belief whose content differs from the actual state of affairs. A false belief is distinct from ignorance: an ignorant agent need not have any particular mistaken representation. False-belief understanding is the capacity to represent and reason about this difference.
