Two experiments observed an effect consistent with a latent-inhibition (LI) effect in humans that (a) did not depend on masking or instruction-generated expectations and (b) suggested that the effect results from a change in processing of t...
Increasing previous but not concurrent extinction attenuates the "extinction makes acquisition context specific" effect in human predictive learning [0.03%]
增加先前的但不是同时的消退会减弱人类预测学习中“消退使习得在特定情境下进行”的效应

Four experiments in human predictive learning evaluated whether the extinction makes the acquisition context specific (EMACS) effect is attenuated when the increase in prediction error that extinction produces disappears. Participants had t...
Stimulus-outcome associations are required for the expression of specific Pavlovian-instrumental transfer [0.03%]
刺激结果联系是表达特定 pavlovian 行为的必要条件

A series of experiments employed a specific Pavlovian-instrumental transfer (PIT) task in rats to determine the capacity of various treatments to undermine two outcome-specific stimulus-outcome (S-O) associations. Experiment 1 tested a rand...
Learning about trial sequences disrupts the partial reinforcement extinction effect in classical conditioning [0.03%]
了解试验序列破坏了经典条件反射中的部分强化灭绝效应

The partial reinforcement extinction effect (PREE) refers to the phenomenon that conditioned responding extinguishes more slowly if subjects had been inconsistently ("partially") reinforced than if they had been reinforced on every trial ("...
The sequencing of trials during partial reinforcement affects subsequent extinction [0.03%]
分批强化期间试验的排序会影响随后的消退过程

If a conditioned stimulus or response has been inconsistently ("partially") reinforced, conditioned responding will take longer to extinguish than if responding had been established by consistent ("continuous") reinforcement. This partial r...
Switching from sucrose to saccharin: Extended successive negative contrast is not maintained by hedonic changes [0.03%]
从蔗糖转换到甜味素：连续的负强化效应不会因享乐变化而保持

Previous experiments found that acceptance of saccharin by rats was reduced if they had prior experience of sucrose or some other highly palatable solution. This reduction in saccharin consumption was particularly extended after a switch fr...
The effects of feature extinction in dual-response feature-positive discriminations [0.03%]
二元反应特征阳性判别中的特征消亡效应

Sara R Bond et al.
In a typical feature-positive discrimination, responding is reinforced (+) during the target stimulus (A) on trials with the feature stimulus (X), but not during target-alone trials (A-). When X and A are presented simultaneously, direct co...
The role of numerical and nonnumerical magnitudes in pigeons' conditional discrimination behavior [0.03%]
数值和非数值大小在鸽子条件化辨别行为中的作用

Research on approximate numerical estimation suggests that numerical representations can be influenced by nonnumerical magnitudes. Current theories of numerical cognition differ on the nature of this interaction. The present project evaluat...

Telling that one object or moment is different from another one is fundamental to cognition and intelligent behavior. Most investigations examining same/different (S/D) concepts in animals have relied on testing static visual stimuli. To mo...

Pavlovian conditioning has been proven to be useful for the study of associative learning and animal cognition. This procedure can be used to observe certain memory phenomena. The appetitive conditioning of several neutral stimuli can resul...
