 take the example of being angry, most people their anger would increase a little bit and they can notice that that anger is there. The threshold for noticing is maybe like 10 or 20 on the scale of 0 to 100 and so it's quite easy to notice those background emotions increasing and also knowing you know being able to know how you feel gives you a better idea of how you're presenting to other people whereas when you're autistic, when you have a lexaphime the threshold for noticing it is probably somewhere sitting between about 70 to 90 percent, 70 to 90 on that scale and so even if it gets up to about 65% and you know that's quite a significant amount of anger, we won't notice it.
