In Figure 1 above, student 1 has is has no channels going to or coming from him, and therefore is disconnected from the rest of the system with respect to the affect relation "guides the learning of". One might see this in a classroom situation as a student who keeps to him/herself and does not interact with the other students in the classroom.
Another example of disconnectedness can be seen in most school systems. With respect to the affect relation "influencing school curriculum", the custodial staff is usually disconnected from the rest of the system.
