But however pain becomes connected to the main cluster, it will certainly provide those established visual, auditory, and tactual images with another powerful anchor, giving them further legitimacy in the psycho-physical parallelism. Since, according to the above hypothesis, only anchors can directly affect an interaction between mind and matter, it follows that our subjective life can only be a valid psycho-physical parallelism to the extent that it is tied to instincts and emotions. That is probably true. It is also suggested that anchors are in no way dependent on images. That may not always be true.
Anger is another possible anchor experience that enhances aggressive behavior.
It s a different kind of aggression than that associated with hunger, because it has to do with defending turf or fighting for dominance within a herd. It can therefore appear as a separate emotion, emerging from a separate evolutionary step, giving us a total of seven independent anchors. However, there is a curious interdependence between anger and fear that is reflected in the body s fight or flight mechanism. Physiologically, it is very difficult to tell the difference between fight arousal and flight arousal. The difference seems to lie in what we might call cortical processes.
