Gabapentin Discriminative Stimulus Effects
… drug effects of gabapentin when established as a discriminative stimulus as well as GABA<sub>A</sub> and NMDA ligands. Ten female Sprague-Dawley rats were trained on a drug discrimination paradigm using a 300.0 mg/kg gabapentin training dose as a discriminative stimulus. Gabapentin was …

Discriminative Stimulus Effects of Gabapentin
<p>The present study sought to evaluate the discriminative stimulus effects of the anticonvulsant gabapentin in rats trained to discriminate 30.0 mg/kg gabapentin from vehicle in a two-lever drug discrimination task. All of the ten rats tested were able to establish gabapentin as an interoceptive …

Discriminative Stimulus Effects of Putative Antipsychotic Drugs
<p>This study attempted to further explore the discriminative stimulus properties of antipsychotic drugs, by establishing the typical antipsychotic drug chlorpromazine, and the atypical antipsychotic drug clozapine as discriminative stimulus in two different groups of rats. The rats trained to …

Discriminative stimulus properties of 3-substituent rimonabant analogs
… These analogs also failed to elicit THC-like discriminative stimulus effects, nor did they antagonize THC’s discriminative stimulus in mice discriminating 5.6 mg/kg THC from vehicle. Finally, mice were trained to discriminate 5.6 mg/kg O-6629 from vehicle. O-6658 produced full substitution for …

Negative Discriminative Stimulus as Punishing Consequence: A new approach to behavioural change
… The first study investigated whether a negative discriminative stimulus will function as a punishing consequence. Pigeons were trained on a multiple schedule to discriminate between a positive discriminative stimulus (S+) signalling the presence of food in one component, and a negative …

The Discriminative Stimulus Properties of the Atypical Antipsychotic Clozapine in C57BL/6 Mice
Serotonin and α1 adrenergic receptor antagonism may contribute to atypical antipsychotic drug effects. Clozapine (2.5 mg/kg) drug discrimination in C57BL/6 mice may selectively screen atypical antipsychotic drugs. Previous data show that the atypical antipsychotics olanzapine, risperidone, …

CONDITIONED REINFORCEMENT FROM SHOCK TERMINATION.
… study addressed the question of whether or not a stimulus paired with the termination of shock would acquire a positive conditioned reinforcing function. Previous investigators have suggested that a stimulus paired with shock termination must increase the frequency of a response upon which it is …

Effects of Click + Continuous Food Vs. Click + Intermittent Food on the Maintenance of Dog Behavior.
… the conditioned reinforcer and also disrupt its discriminative stimulus function. A within subjects reversal design was used with 2 dogs to compare the behavioral effects of continuous pairings (C+F condition) vs. intermittent pairings (C+C+F condition) of the clicker with food. Results show that …

The Effect of a Lag Schedule of Reinforcement on Variability in Toy Play in Children with Autism
… diagnosed with autism, both studies used the discriminative stimulus (SD) “build differently,” during intervention phases. The current study used a lag schedule of reinforcement along with the SD “build something,” throughout each phase. The results of this study showed that a lag schedule of …

Effects of Environmental Enrichment on Learning a Discrimination Task by Captive White-spotted Bamboo Sharks (Chiloscyllium plagiosum)
… enrichment, the sharks appeared to associate a discriminative stimulus (black vs. white tile) with food, but they did not discriminate between the tiles without a food reward. After a 68-d non-testing period followed by 10 d of exposure to enrichment objects (two plastic hula hoops) in the …

An experimental analysis of a coding response theory of discrimination learning
… the presence of experimental stimuli and produce discriminative stimulus consequences, and 2) code items are values or a particular stimulus dimension, were assumed by the experimental conditions. The other two rules, 1) coding responses might be any artibrary response topography, and 2) coding is …

Instrumental conditioning and learning in Poroderma Pantherinum
… with black and white stripes was used as the discriminative stimulus, while an auditory cue acted as a bridging stimulus for the food-reward task. Sharks were collected by hand whilst diving and shore-angling in Hermanus from August 2015 to November 2015 and acclimatised before the onset of …

EFFECTS OF STIMULUS COMPLEXITY, SUBJECT AGE, AND STIMULUS CODING ON SELECTIVE STIMULUS CONTROL
<p>Selective stimulus control refers to the functional relationships that are developed between the various stimulus elements of a discriminative stimulus and the subject's response. A multi-element conditional discrimination problem is an effective means of studying these relationships. In the …

Mind reading as behaviour reading: Behavour analysis and perspective taking
… of another person, and how the acquired stimulus functions are generalised to novel contexts. First, I examined the integrity of the concept of “deictic framing,” which proposes that deictic expressions (I-You, Here-There, Now-Then) are the core components of perspective-taking behaviour, …

The Effects of Combining Positive and Negative Reinforcement During Training.
… alone. A behavior was trained under two stimulus conditions and procedures. One method involved presenting the cue ven and reinforcing successive approximations to the target behavior. The other method involved presenting the cue punir, physically prompting the target behavior by pulling …
