| Abstract |
|
Speed with which 9 turtles (Chrysemys picta marginata) traversed a 36 in. runway following 2-hr. and 6-hr. periods of dry confinement in small cells was more than double the speed immediately following withdrawal from S's home tank. Using antecedent confinement and contingent natation or disorientation for correct and incorrect choices, respectively, this species demonstrated intermediate brightness discrimination. 4 or 5 Ss learned a black-gray discrimination in 8-66 trials. In a discrimination involving the same gray and a white cue, S's failure to give clear evidence of responding either to relational or absolute stimulus properties is probably the consequence of sensory deficiencies, a finding supported by failure of 4 other Ss to learn a gray-white discrimination.
