This is one of my fav papers: How (not) to train your spider: successful and unsuccessful methods for studying learning http://www.tandfonline.com/doi/abs/10.1080/03014223.2015.1127263?journalCode=tnzz20 http://www.tandfonline.com/doi/abs/10.1080/03014223.2015.112... Because it has all the failed methods for training them that never got published. Some of them are unintentionally hilarious too. > In our laboratory, we also used sprays of water as an aversive stimulus—spiders that moved into one side of an arena received a spray of water. In pilot trials, there was no evidence of learning: spiders ran wildly when sprayed and then stopped to groom themselves. If accidentally sprayed too heavily, they became trapped by the water droplet. I think more papers like this should exist.
