The individual undergoing it is male, healthy, in his very early thirties, does not thrive on isolation or lack of activity, and is forced into the experiment against his will. He's highly intelligent and like a lot of HSPs, is used to processing vast amounts of information regarding his surroundings, but I haven't been able to turn up anything in my research on what the impact of sensory deprivation on him would be as a result. Most of what I've found has been regarding consensual experiences for non-HSPs.
I'm looking for anything which can help me understand what his mindset would be after he's rescued, including immediately after rescue and possibly a few months down the road. I'd like to know what, if any, impact this could have on him. I've read that short term sensory deprivation can lead to heightened suggestibility and that the experiments done for BBC's Total Isolation documentary (48 hours of complete sensory deprivation) recovered fully within a relatively short time frame. Their experience was both shorter and consensual, with the knowledge that they could end the experiment at anytime though, so I'm not sure how well my character's experience would match up to them.
I've tried Googling a number of things without being able to drill down into what I'm looking for, including "mkultra", "effects of sensory deprivation on hyperaware individuals", "ganzfeld experiments" and so on as well as checked the last hundred entries in this comm to see if anyone else had made a post regarding sensory deprivation recently. Wikipedia has some good basic info, as did Wired Science, but I'm really curious what the group might be able to turn up.
Any help at all would be really appreciated! (As well as any advice on how to tag this - I'm not really sure where it would fit best.)
