Instrumental and Pavlovian incentive processes have dissociable effects on components of a heterogeneous instrumental chain [0.03%]

Two experiments compared the effects of Pavlovian stimuli and incentive learning on the performance of a heterogeneous chain of instrumental actions. Using a Pavlovian-instrumental transfer design, the authors found that only a stimulus pai...
Pigeons learn stimulus identity and stimulus relations when both serve as redundant, relevant cues during same-different discrimination training [0.03%]
pigeons在相同-不同辨别训练中同时作为服务冗余、相关线索时学习刺激身份和刺激关系

The authors taught pigeons to discriminate displays of 16 identical items from displays of 16 nonidentical items. Unlike most same-different discrimination studies--where only stimulus relations could serve a discriminative function--both t...
Differential effects of adding and removing components of a context on the generalization of conditional freezing [0.03%]

Rats were conditioned across 2 consecutive days where a single unsignaled footshock was presented in the presence of specific contextual cues. Rats were tested with contexts that had additional stimulus components either added or subtracted...
Importance of trials versus accumulating time across trials in partially reinforced appetitive conditioning [0.03%]

Four experiments with rats examined partial reinforcement in appetitive conditioning. In Experiment 1, adding nonreinforced trials to a continuous reinforcement schedule slowed acquisition, whereas deleting reinforcers did not. Trial massin...
Complex dynamic processes in sign tracking with an omission contingency (negative automaintenance) [0.03%]

Hungry pigeons received food periodically, signaled by the onset of a keylight. Key pecks aborted the feeding. Subjects responded for thousands of trials, despite the contingent nonreinforcement, with varying probability as the intertrial i...
Perceptual learning in flavor aversion: evidence for learned changes in stimulus effectiveness [0.03%]

Rats were exposed to the compound flavors AX and BX, presented in alternation, and to CX on a separate block of trials. Generalization to BX after aversion conditioning with AX was less than to CX. An equivalent effect was found when the na...

Four conditioned lick suppression experiments with rats examined the effect of trial spacing on cue interaction. Experiments 1 and 2 found overshadowing to be eliminated with massed compound stimulus-outcome pairings and the usual trial spa...
Interacting Cache memories: evidence for flexible memory use by Western Scrub-Jays (Aphelocoma californica) [0.03%]
关于加州鸦（Aphelocoma californica）利用灵活的记忆的证据：相互作用的缓存记忆

When Western Scrub-Jays (Aphelocoma californica) cached and recovered perishable crickets, N. S. Clayton, K. S. Yu, and A. Dickinson (2001) reported that the jays rapidly learned to search for fresh crickets after a 1-day retention interval...
An analysis of response, direction, and place learning in an open field and T maze [0.03%]

Rats were trained to locate food in a response, direction, or place problem on an open field located at 2 positions. In Experiment 1, both the response and direction groups solved the problem. The place group failed to solve the task in app...

Timing in pigeons: effects of the similarity between intertrial interval and gap in a timing signal [0.03%]
定时信号中间隔与间隙的相似性对鸽子时间判断的影响
Daren H Kaiser,Thomas R Zentall,Emily Neiman
Daren H Kaiser
Previous research suggests that when a fixed interval is interrupted (known as the gap procedure), pigeons tend to reset memory and start timing from 0 after the gap. However, because the ambient conditions of the gap typically have been th...
