Four rhesus monkeys (Macaca mulatta) were tested on joystick-based computer tasks in which they could choose to be reinforced either with pellets-only or with pellets + video. A variety of videotapes were used to reinforce task performance....

Rats were trained on a delayed successive matching-to-stimulus modality task consisting of onset of chamber lights or a tone for the sample stimulus, S1, and a comparison stimulus, S2. Lever pressing to S1 was reinforced as was lever pressi...
Pairings of a Circular Alley with Apomorphine Produce Conditioned Hyperactivity [0.03%]
圆巷与阿朴吗啡配对产生条件性多动行为

BT Lett
During training trials, some rats were injected with apomorphine as the unconditioned stimulus immediately before (Group Forward) or 15 min before (Group Backward) exposure to the conditioned stimulus, a circular alley where locomotor activ...

Three experiments examined the effect of reinforcement magnitude on free-operant response rates. In Experiment 1, rats that received four food pellets responded faster than rats that received one pellet on a variable ratio 30 schedule. Howe...
Signaled Delay of Reinforcement: Effects of Postconditioning Manipulation of Context Associative Strength on Instrumental Performance [0.03%]
延迟强化的信号：后条件化操纵情境联结强度对仪器绩效的影响

Two experiments examined the influence of postconditioning treatments of contextual cues on instrumental responding acquired with a signaled delay of reinforcement schedule. In Experiment 1, mere exposure to the conditioning context after i...
The Effect of a Discrete Signal on Context Conditioning: Assessment by Preference and Freezing Tests [0.03%]
离散信号对条件作用的影响：偏爱和冻结试验评估结果

JHR Maes
Four experiments with rats assessed conditioning to contextual cues after the delivery of footshocks that were either signaled by a discrete stimulus or unsignaled. Two different tests were used. The first was a context preference test in w...

Rats pressed levers for food delivered by several fixed interval schedules. A drinking spout or running wheel was also available during some conditions, but not during others. The rate of lever pressing, drinking and running often changed w...
Manipulation of Components of Context: The Context Shift Effect and Forgetting of Stimulus Attributes [0.03%]
操纵情境的组成部分：情境转换效应和刺激特征遗忘现象

Seventy-two Sprague-Dawley rats were used to investigate the multidimensional features of the context shift effect and the forgetting of stimulus attributes in a Pavlovian differential fear conditioning paradigm. One day after training, a c...

Rats' learning about visual patterns was studied in a computerized Y-maze where wide-angle stimuli were viewed from a distance. Many patterns were available; some were spatially complex and others were more homogeneous figures. Experiment 1...
