Demand for food and cocaine in Fischer and Lewis rats.
30 Jan 2009 
Fischer and Lewis rat strains often serve as animal vulnerability models for drug abuse and addiction. When these strains respond for drugs of abuse, several measures, including total drug intake, response rate and progressive-ratio breakpoints, ...

Modeling the dynamics of choice.
29 Jan 2009 A simple linear-operator model both describes and predicts the dynamics of choice that may underlie the matching relation. We measured inter-food choice within components of a schedule that presented seven different pairs of concurrent ...

29 Jan 2009 Four pigeons were exposed to a concurrent-chains procedure in which the initial link was constant (variable-interval 10s) while the terminal-link delays changed across sessions according to a pseudorandom binary series. In the short condition, the ...

[Neglected children: birth, life and survival]
22 Jan 2009 Child neglect leads to numerous and serious consequences. The physical and neurophysiological development can be altered by the lack of stimulation or via a chronic stress which increases the production of cortisol. Gradually, psychomotor and ...

21 Jan 2009 RATIONALE: Previous studies indicated that ethanol could be self-infused into the posterior ventral tegmental area (p-VTA) and that activation of local serotonin-3 (5-HT(3)) receptors was involved. 5-HT(1B) and 5-HT(2A) receptors are involved in the ...

An investigation of increases in metamemory confidence across multiple study trials.
21 Jan 2009 We employed a list-learning methodology to investigate whether discrepancies between mean judgements of learning (JOLs) and recall in a multiple study-recall context reflects a metacognitive failure in applying the knowledge that repeated study ...

Effects of d-amphetamine on behavior maintained by signaled and unsignaled delays to reinforcement.
20 Jan 2009 Four pigeons responded under a progressive-delay procedure. In a signaled-delay condition, a chained variable interval (VI) 30-s progressive time (PT) 4-s schedule was arranged; in an unsignaled-delay condition, a tandem VI 30-s PT 4-s schedule was ...

19 Jan 2009 The current study assessed the effects of developmental PCB and/or MeHg exposure on an operant task of timing and inhibitory control and determined if amphetamine (AMPH) drug challenges differentially affected performance. Long-Evans rats were ...

19 Jan 2009 Schizophrenia symptoms can be segregated into positive, negative and cognitive, which exhibit differential sensitivity to drug treatments. Accumulating evidence points to efficacy of alpha7 nicotinic receptor (nAChR) agonists for cognitive deficits ...

Effects of unpredictable changes in initial-link duration on choice and timing.
19 Jan 2009 Four pigeons responded in a concurrent-chains procedure in which terminal-link schedules were fixed-interval (FI) 10s and FI 20s. Across sessions, the location of the shorter terminal-link changed according to a pseudorandom binary sequence. Each ...
