I have a p. pederseni sling 2 inches in an acrylic cube. When I pick the cube up, the spider doesn't move. If I tap on the acrylic once, the spider does nothing. But, if I tap twice it goes to its burrow. What's funny is I always tap twice and wait for it to go to its burrow before throwing in a dubia. I guess my question is have I conditioned it to go to it's burrow before feeding (aka pavlov and his dog)?
