Journal ArticleDOI
Multiple-choice procedure: an efficient approach for investigating drug reinforcement in humans.
TL;DR: Two experiments demonstrated the efficiency of assessing drug reinforcement in humans by using a novel multiple-choice procedure evaluated in twelve male drug abusers and demonstrated dose-related choice of pentobarbital over money as well as choice of a higher dose of pent BARBital over a lower dose or placebo.
Journal ArticleDOI
Extinction of cue-evoked drug-seeking relies on degrading hierarchical instrumental expectancies
Lee Hogarth,Lee Hogarth,Chris Retzler,Marcus R. Munafò,Dominic M. D. Tran,Joseph R. Troisi,Abigail K. Rose,Andrew Jones,Matt Field +8 more
TL;DR: The results showed that the ability of a drug stimulus to transfer control over a separately trained drug-seeking response was not affected by the stimulus undergoing Pavlovian extinction training, and methods which degraded this hierarchical expectancy were effective in the laboratory, and so may have therapeutic potential.
Journal Article
Tandospirone and alprazolam: comparison of behavioral effects and abuse liability in humans.
TL;DR: The overall profile indicates that tandospirone has a significantly lower abuse liability than does alprazolam and can be clearly differentiated on the basis of subjective effects and performance measures.
Journal ArticleDOI
Signals for shock-free periods during chronic exposure to delayed-escapable and inescapable shocks: Effects on later escape acquisition
TL;DR: The authors investigated the acquisition of shock-escape responses in an illuminated shuttlebox following chronic exposure to shock that was escapable after a 2-s delay (ES) and to yoked inescapable shock (IS) under conditions in which 5-s house-light presentations signaled shock-free periods (CS−) of variable duration.
Journal ArticleDOI
Negative mood reverses devaluation of goal-directed drug-seeking favouring an incentive learning account of drug dependence.
Lee Hogarth,Zhimin He,Henry W. Chase,Andy J. Wills,Joseph R. Troisi,Adam M. Leventhal,Amanda R. Mathew,Brian Hitsman +7 more
TL;DR: It is suggested that negative mood augments drug-seeking by raising the expected value of the drug through incentive learning, rather than through automatic S-R control.
