Assessment Of Dopaminergic And Serotonergic Receptor Antagonists In Male Rats Trained To Discriminate 4-Methylmethcathinone (Mephedrone), Rachel L. Burroughs

Preclinical drug discrimination studies of the synthetic cathinone, 4-methylmethcathinone (mephedrone) have demonstrated its effects are comparable to those of other popular psychostimulant drugs. Few studies have directly examined the contribution of specific neurotransmitter receptors to mephedrone’s discriminative stimulus effects. The present study investigated the role of dopamine and serotonin receptors in these effects. Eight adult male Sprague-Dawley rats were trained to discriminate 3.0 mg/kg mephedrone from saline. After dose-response curves were determined with mephedrone (0.375-3.0 mg/kg), a series of stimulus antagonism tests were conducted with dopamine antagonists (Sch 23390, haloperidol) and serotonin antagonists (WAY 100,635, MDL 100,907, pirenperone) administered as …
Can’T Stop: The Effects Of High-P Sequencing On Fluency And Retention, Andrew R. Smith
Can’T Stop: The Effects Of High-P Sequencing On Fluency And Retention, Andrew R. Smith
Masters Theses
Precision teaching has led to successful outcomes in both training and education. Past research has shown that by using flashcard techniques such as SAFMEDS in ratebuilding exercises, one can expect expert levels of performance and retention of learned material by practicing for a minute a day. Fluency training using SAFMEDS could prove invaluable in businesses that wish to train their employees using cost and time efficient methods. However, recent research has shown that the SAFMEDS sequence may not quickly build accurate rates of responding in earlier sessions, or reliably lead to high levels of retention. High probability (high-p) sequences can …
Examination Of The Impact Of Contingent Praise And Monetary Rewards On Intrinsic Motivation And Creative Performance, Merrilyn Akpapuna
Examination Of The Impact Of Contingent Praise And Monetary Rewards On Intrinsic Motivation And Creative Performance, Merrilyn Akpapuna
Masters Theses
Despite many decades of debate, the question of whether or not extrinsic motivation is detrimental to intrinsic motivation and creativity continues to spark discussion among professionals (Cameron & Pierce, 1994). This is an important issue for business owners who do not want to stifle creativity and intrinsic motivation in an effort to increase productivity. Even though many authors have labelled extrinsic motivation as archaic and harmful (Deci, 1971; Kohn, 1993; Pink, 2009), the available empirical evidence does not match such levels of condemnation. The purpose of the present study was to compare the effectiveness of several interventions (performance-contingent money, performance-contingent …
