Abstract

The purpose of this study was to examine the effects of GHB under a negative auto maintenance procedure. Four female White Carneaux pigeons were utilized as subjects. The pigeons were first subjected to an auto shaping procedure, in which brief key illuminations were followed by food delivery, regardless of a bird's' behavior. Pecking to the lighted key occurred at high rates after repeated pairings, a finding corroborated by prior research. A negative auto maintenance procedure was then implemented. During this procedure, responding to the lighted key prevented access to the grain. As expected from previous investigations, results indicated a decrease in responding. The subjects then began drug trials. Three doses of GHB (100, 200, and 400 mg/kg)were administered. Results indicated that GHB decreased or had no effect on responding.
