    • Development of a One Week Delay Discounting Procedure For Use in the Nonhuman Laboratory 

      Salzer, Allyson R.; Markham, Eric N.; Balsavich, Janel E.; Lagorio, Carla H. (2018-01-24)
      The current study tested and compared results from three variations of delay discounting procedures – one that is widely reported in the literature, and two novel variations. The novel procedures were designed to assess ...
    • Discriminative Stimulus Effects of Naltrexone and Haloperidol in Rats With Chronic, Intermittent Access to Sucrose 

      Jewett, David C.; Marek, Morgan A.; Moline, Adam D.; Hadorn-Papke, Damin J.; Vogelsang, Jenna D.; Wallner, Michelle A.; Cyra, Matthew D.; Todd, Justin A.; Moe, Simon M.; Eichstadt, Rachel M.; Altendorf, Luke R.; James, Kimberly F. (2017-12-05)
      Our previous research has shown that naltrexone can be established as a discriminative stimulus for rats given daily sucrose solutions and trained under a 3.2 mg/kg training dose (TD). Our current study attempts ...
    • Discriminative stimulus effects of naltrexone in rats with limited access to sucrose 

      Marek, Morgan A.; Moe, Simon M.; De Roach, Elliott; Warner, Jamie; James, Kimberly F.; Altendorf, Luke R.; Paukner, Dawn; Thai, Calvin; Herrmann, Jody; Jewett, David C.; Rolefson, Kelsey; Moline, Adam D.; Eichstadt, Rachel M.; Wachholz, Blake; Edwards, Paige A.; Virnig, Austin (2017-03-14)
      Naltrexone, an opioid antagonist, is not discriminable at typical doses in operant paradigms. We attempted to establish naltrexone as a discriminative stimulus in rats given 12-hour dark cycle access to sucrose solutions. ...
    • Effects of the Environment and Deprivation Condition in Aged Rats Trained to Discriminate Between 22- and 2-hr Food Deprivation 

      Todd, Justin A.; Moe, Simon M.; Eichstadt, Rachel M.; Wallner, Michelle A.; Cyra, Matthew D.; Vogelsang, Jenna D.; Jewett, David C. (2018-02-14)
      Jewett and collegues (2005) have previously trained rats to discriminate between food deprivation of 2 hours and 22 hours, and found 20 minute access to food reduced the stimulus effects of food consumption. In our ...
