A specialization of Event_Localized. Each instance of IntrinsicStateChangeEvent is an event characterized primarily by a change in some intrinsic property of at least one main actor involved in the event. Such intrinsic changes may include changes of a thing's color, temperature, device state, or size. Events where the main change is extrinsic (such as a change in location or ownership) are not instances of IntrinsicStateChangeEvent. In events which have more than one actor, the event may be an IntrinsicStateChangeEvent for one actor but not for another. For example, in a FasteningSafetyBelt event, the SafetySeatBelt (the device used) goes from unconnected to connected (to itself), which is an intrinsic change; however, the agent who does the fastening does not change intrinsically, but only in his configuration to the belt, an external object. Another example: in a HairCuttingEvent, the hair that is cut undergoes an IntrinsicStateChangeEvent due to its role in that kind of event, but the barber undergoes no intrinsic change due to the hair cutting. Note that some events, such as an ice cube melting into a small puddle of water, could be represented either as an IntrinsicStateChangeEvent or as a PhysicalTransformationEvent, but not (within a single micro-theory) as both.
