Context-US association as a determinant of long-term habituation in the crab chasmagnathus

An opaque screen moving overhead elicits an escape response in the crab Chasmagnathus that habituates for a long period after just a few presentations. A series of experiments was performed to determine whether the crab's long-term habituation (LTH) is mediated by an association between context...
