Nicotine withdrawal and reward responsivity in a card-sorting task.
15 Jan 2009 
RATIONALE: Animal studies have demonstrated decreased reward responsivity during nicotine withdrawal (e.g., Epping-Jordan et al., Nature 393:76-79, 1998) and the Card Arranging Reward Responsivity Objective Test (CARROT) has recently been used to ...

15 Jan 2009 In the present study, effects of d-amphetamine on sensitivity to reinforcement amount under concurrent schedules were examined using a rapid-acquisition procedure. Four pigeons key pecked under single concurrent variable-interval 30-s schedules of ...

13 Jan 2009 BACKGROUND: Cocaine and methamphetamine (METH) are two commonly abused drugs that have behavioral-stimulant properties. These stimulant effects are partially mediated by the dopaminergic system. Recent evidence has suggested that the histamine H(3) ...

12 Jan 2009 RATIONALE: A differential-reinforcement-of-low-rate schedule (DRL) delivers reinforcement only when the interresponse time (IRT) exceeds a fixed time interval, thereby shaping rats to discriminate the timing of their responses. However, little is ...

Operant sensation seeking engages similar neural substrates to operant drug seeking in C57 mice.
12 Jan 2009 Novelty and sensation seeking have been associated with elevated drug intake in human and animal studies, suggesting overlap in the circuitry mediating these behaviors. In this study, we found that C57Bl/6J mice readily acquired operant responding ...

7 Jan 2009 RATIONALE: Mesolimbic dopamine (DA) is a critical component of the brain circuitry regulating behavioral activation and effort-related processes. Research involving choice tasks has shown that rats with impaired DA transmission reallocate their ...

Differential place and response learning in horses displaying an oral stereotypy.
6 Jan 2009 Significant similarities exist between the neural and behavioural features of environmentally and drug-induced stereotypy. For example, exposure to dopamine agonists, such as amphetamine, induces stereotypy and causes alterations in midbrain ...

A demonstration of individual preference for novel mands during functional communication training.
30 Dec 2008 Preference for mand topography was evaluated for 2 individuals with developmental disabilities who exhibited problem behavior. The results of a functional analysis showed that each participant's problem behavior was maintained by social ...

Using percentile schedules to increase eye contact in children with Fragile X syndrome.
30 Dec 2008 Aversion to eye contact is a common behavior of individuals diagnosed with Fragile X syndrome (FXS); however, no studies to date have attempted to increase eye-contact duration in these individuals. In this study, we employed a percentile ...

An evaluation of resurgence during treatment with functional communication training.
30 Dec 2008 Extinction-induced resurgence is the recurrence of previously reinforced behavior when another behavior is placed on extinction (Lieving, Hagopian, Long, & O'Connor, 2004). This phenomenon may account for some instances of treatment relapse when ...
