A behavior control apparatus to control behavior of a device capable of sensing a state of an environment and selecting an action on the basis of a sensing result is provided. The behavior control apparatus includes a predicting unit configured to learn the action and change in the state of the environment and predict change in the state of the environment caused by a predetermined action on the basis of the learning; a planning unit configured to plan a behavior sequence to achieve a goal state from a present state on the basis of the prediction made by the predicting unit; and a control unit configured to control each action of the behavior sequence planned by the planning unit and learn an input/output relationship if the goal state is achieved through the action.
