Is there a dissociation between emotional feelings and emotional signs in autism?

There is evidence that autistic persons are deficient both in the expression and recognition of emotion. Emotions are viewed here as in part genetically determined, inborn behaviours with great importance for social regulations. Both in phylogenetic and in ontogenetic development there is a transgression from emotion-bound or signal-reflex-like behaviour chains towards an experience-based coupling of emotional signals with events lying outside emotional exchanges. We conjecture that in childhood autism there is a deficit in linking biologically based emotional signals to emotional experiences and/or a deficit in linking these signals to a third element. Mesocortical areas with close connections to the limbic systems appear to be involved.
