My initial research into GCP seems to originate within the context of SLP who specialize in GLP. One SLP referred to monotropism in relation to GCP.

I’ve saved some quotes here, but I don’t completely agree with everything presented as monotropism in this paper. I think this is based on somewhat outdated research and a narrow view of autism.

“To a person in an attention tunnel every unanticipated change is abrupt and is truly, if briefly, catastrophic: a complete disconnection from a previous safe state, a plunge into a meaningless blizzard of sensations, a frightening experience which may occur many times in a single day. Following such an episode it may take a long time for any other interest to emerge.”

“For a monotropic thinker, if something does not work out as anticipated there are no alternatives available as there would be for a polytropic thinker. Instead of the projected outcome there is total disaster (Lawson, 1998). Total disaster is strongly demotivating.”

“features of the environment which seem obvious to people with diffuse rather than tightly focused attention may be entirely missed.”
