There are some very cool projects going on in spider science these days.
In one study, jumping spiders are induced to climb small viewing towers to contemplate experimentally manipulated images of prey. In another, wolf spiders are invited to assess visual and vibratory signals, digitally altered in various ways, that represent qualities of their potential mating partners.
Innovative methods are being used to ask the question, "What goes on in the mind of spiders?" The results suggest that the answer is "quite a lot."
