Timing with opportunity cost: concurrent schedules of reinforcement improve peak timing.
30 Jul 2009 
The temporal generalization gradient produced by the peak-interval (PI) procedure reflects behavior under the control of positive reinforcement for responding after the criterial time, but shows negligible discouragement for early responses. The ...

Explicit melioration by a neural diffusion model.
28 Jul 2009 When faced with choices between two sources of reward, animals can rapidly adjust their rates of responding to each so that overall reinforcement increases. Herrnstein's 'matching law' provides a simple description of the equilibrium state of this ...

Midbrain dopamine neurons signal preference for advance information about upcoming rewards.
14 Jul 2009 The desire to know what the future holds is a powerful motivator in everyday life, but it is unknown how this desire is created by neurons in the brain. Here we show that when macaque monkeys are offered a water reward of variable magnitude, they ...

Lack of cocaine self-administration in mice expressing a cocaine-insensitive dopamine transporter.
12 Jul 2009 Cocaine addiction is a worldwide public health problem for which there are no established treatments. The dopamine transporter (DAT) is suspected as the primary target mediating cocaine's abuse-related effects based on numerous pharmacological ...

8 Jul 2009 The matching law (Herrnstein 1961) states that response rates become proportional to reinforcement rates; this is related to the empirical phenomenon called probability matching (Vulkan 2000). Here, we show that a simple artificial neural network ...

7 Jul 2009 Children with attention-deficit/hyperactivity disorder (ADHD) show an impaired ability to use feedback in the context of learning. A stimulus-response learning task was used to investigate whether (1) children with ADHD displayed flatter learning ...

The behavioral economics of choice and interval timing.
29 Jun 2009 The authors propose a simple behavioral economic model (BEM) describing how reinforcement and interval timing interact. The model assumes a Weber-law-compliant logarithmic representation of time. Associated with each represented time value are the ...

29 Jun 2009 Persistent drug seeking is a defining property of substance abuse and is generally thought to depend, in part, on exposure to drug-associated contexts. Behavioral momentum theory provides a set of methods and a theoretical framework for ...

Learning about associations: evidence for a hierarchical account of occasion setting.
29 Jun 2009 In 2 experiments rats were trained on a switching discrimination, with 4 occasion setters, A, B, C, and D and 2 target stimuli, x and y. When signaled either by A or by B, x was reinforced with food and y was not, whereas when signaled either by C ...

Averaging of temporal memories by rats.
29 Jun 2009 Rats were trained on a mixed fixed-interval schedule in which stimulus A (tone or light) indicated food availability after 10 s and stimulus B (the other stimulus) indicated food availability after 20 s. Testing consisted of nonreinforced probe ...
