Three experiments examined the processes mediating rat serial pattern learning for rule-consistent versus rule-violating pattern elements ("violation elements"). In all three experiments, rats were trained to press retractable levers in a c...

Pigeons show a preference for an alternative that provides them with discriminative stimuli (sometimes a stimulus that predicts reinforcement and at other times a stimulus that predicts the absence of reinforcement) over an alternative that...
The Modulation of Operant Variation by the Probability, Magnitude, and Delay of Reinforcement [0.03%]
强化的概率、大小和延迟能够调节操作变异行为的水平

Recent studies have demonstrated that the expectation of reward delivery has an inverse relationship with operant behavioral variation (e.g., Stahlman, Roberts, & Blaisdell, 2010). Research thus far has largely focused on one aspect of rein...
Mechanisms of resurgence II: Response-contingent reinforcers can reinstate a second extinguished behavior [0.03%]
复发机制II：反应相伴的强化能恢复第二个已经消退的行为

Three experiments with rat subjects examined resurgence of an extinguished instrumental response using the procedure introduced by Epstein (1983) with pigeons. There were three phases: (1) initial acquisition of pressing on a lever (L1) for...

Reinforcing value and habituation are two processes that have been used to study eating behaviors, but no research has examined their relationship, how they relate to energy intake, and whether they respond in a similar manner to food depri...

Individual vocal recognition behaviors in songbirds provide an excellent framework for the investigation of comparative psychological and neurobiological mechanisms that support the perception and cognition of complex acoustic communication...
Explicit disassociation of a conditioned stimulus and unconditioned stimulus during extinction training reduces both time to asymptotic extinction and spontaneous recovery of a conditioned taste aversion [0.03%]
在消退训练期间明确分离条件刺激和非条件刺激可以减少味觉厌恶的建立时间及自发恢复现象

Conditioned taste aversions (CTAs) may be acquired when an animal consumes a novel taste (CS) and then experiences the symptoms of poisoning (US). This aversion may be extinguished by repeated exposure to the CS alone. However, following a ...
Effects of stimulus duration and choice delay on visual categorization in pigeons [0.03%]
反应时和刺激时间对鸽子视觉分类的影响研究

Olga F Lazareva
We (Lazareva, Freiburger, & Wasserman, 2004) previously trained four pigeons to classify color photographs into their basic-level categories (cars, chairs, flowers, or people) or into their superordinate-level categories (natural or artific...
Natural Choice in Chimpanzees (Pan troglodytes): Perceptual and Temporal Effects on Selective Value [0.03%]
自然选择中的黑猩猩（Pan troglodytes）：感知和时间对选择价值的影响

In three experiments, four chimpanzees made choices between two visible food options to assess the validity of the selective value effect (the assignment of value to only the most preferred type of food presented in a comparison). In Experi...
Constraints on Enhanced Extinction Resulting from Extinction Treatment in the Presence of an Added Excitor [0.03%]

Three Pavlovian fear conditioning experiments with rats as subjects explored the effect of extinction in the presence of a concurrent excitor. Our aim was to explore this particular treatment, documented in previous studies to deepen extinc...
