Perceiving Behavior -- Major Issues

1. The fundamental problem: perceive-respond-predict
2. The human dimension: intentional action
3. Folk concepts/theories vs. philosophical/scientific concepts and theories
4. Children vs. adults

The Folk Concept of Intentionality

1. Agreement in judgments
2. Components of the concept
3. Various tests (belief + desire Ë intention; intention vs. intentionality; intention + skill + awareness Ë intentionality)

The Philosophical Analysis of Intentionality

1. Subtle questions:
   • Is desire necessary?
   • Does intention require belief?
   • Can there be intentionality without intention?
   • How about probabilistic skill?
   • What exactly does awareness mean?
2. Implications for morality

The Child's Theory of Mind

1. Why "theory"?
2. Model: beliefs + desires -> action
3. Sequence: desire concept before belief concept
4. Precursors: emotion, gaze, 'agency'

Lacking a Theory of Mind

1. The wide range of uses (self and other)
2. Problems in schizophrenia
3. Problems in autism
