Ellis and Young (1990) consider these findings to provide some support for their thesis that there are two dissociable pathways involved in face recognition; a perceptual pathway, and an affective one.
Related to my post for the prevoius thread, is there any evidence that it is the affective pathway that is messed up in these delusional subjects?
Ellis and Young, (1990) do not explicitly consider the function of the affective pathway, except to postulate that its malfunction is responsible for the production of the anomalous experience that features in the Capgras delusion.
OK, so they speculate that it is the AFFECTIVE pathway that is messed up. why do they postulate this? is it possible that extreme emotion caused the pathway to misfunction and cause the delusion? i am still considering the notion that extreme emotion is the start for some to a delusion. when i say for some, i mean that not everyone in severe emotional distress becomes delusional, but for those who are delusional, it started with extreme emotion.
this is all very interesting for me. i did a literature review a while back on whether being manic or depressed and having OCD would lower the "delusional threshold" and result in mere obsessions becoming delusions. i didn't find much, actually. i am somewhat familiar with research in face recognition b/c my cognitive psychology prof was doing research on it at the time and included a lot of it in the class lectures.
