I don't know about psycho feeders as I havn't had many that would take food from my hands. Majority would only accept food (rather slowly at that) off the floor & reminded me alot of vens.

However from reading others experiences I would say they have a strong feeding response if they they think it's lunch time & may mistake handling for feeding if they they smell food on your hands. And once they latch on it takes awhile before they realise the mistake & let go. You should practice using soap or hand wash before any handling anyway to avoid this with any species of snake IMO.
