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 ...

Erythropoietin improves operant conditioning and stability of cognitive performance in mice.
6 Jul 2009 
BACKGROUND: Executive functions, learning and attention are imperative facets of cognitive performance, affected in many neuropsychiatric disorders. Recently, we have shown that recombinant human erythropoietin improves cognitive functions in ...

Jul 2009 In monkeys proficient in the performance of a computer-assisted delayed response task, administration of sub-sedative doses of ketamine significantly impaired task performance after the 2mg/kg dose, producing a decrease in accuracies across all four ...

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 ...

Behavioral studies of umami: tales told by mice and rats.
29 Jun 2009 Psychophysical research with rats and mice has been instrumental in understanding umami taste transduction and perception. Although early studies suggested that an NMDA-like receptor detected substances that elicit an umami taste, studies using ...

Individual differences in response to novelty and the conditioned locomotor effects of nicotine.
29 Jun 2009 Rats' locomotor reactivity to an inescapable novel environment has been shown to be correlated with the psychomotor response to many stimulant drugs. However, the effects of nicotine on rats categorized as high responder (HR) or low responder (LR) ...

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 ...

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 ...

Resolution of conflict between goal-directed actions: outcome encoding and neural control processes.
29 Jun 2009 According to O-R theory of instrumental learning, incongruent biconditional discriminations should be impossible to solve in a goal-directed manner because the event acting as the outcome of one response also acts as a discriminative stimulus for an ...

Resistance to change within heterogeneous response sequences.
29 Jun 2009 Three experiments investigated how instrumental and Pavlovian contingencies contribute to resistance to change (RTC) in different ordinal response positions within heterogeneous response sequences in pigeons. RTC in the initial and terminal response ...
