"I'm not keen on spiders and having a functioning brain I realise a holiday to Spider Island would certainly not help my fear."
Actually, it might - it's a technique called "flooding", basically the opposite of desensitisation. Rather than "Here's a piece of paper with the word spider on it, now here's a drawing of a spider, here's a photo of a spider, a small dead spider in a box, a live spider in a box, a live spider on my hand" it goes "Could you just take a seat in the next room? WHICH IS FULL OF SPIDERS!" See http://en.wikipedia.org/wiki/Flooding_(psychology)
