Western scrub-jays (Aphelocoma californica) did not show extinction when caching behavior was never rewarded and they had no choice of where to cache the food. However, when the jays had the choice of caching items in 2 different locations ...

Four experiments assessed the effects of trial (T) and intertrial (I) durations on magazine approach behavior in rats. In Experiments 1 and 2, different groups of animals were conditioned with various combinations of I and T durations. The ...

Preexposure of a cue without an outcome (X-) prior to compound pairings with the outcome (XZ-->O) can reduce overshadowing of a target cue (Z). Moreover, pairing a cue with an outcome (X-->O) before compound training can enhance its ability...

Rats were trained on a temporal switching discrimination, with 2 features, A and B, signaling 2 target conditioned stimuli, x and y; feature offset and target onset were separated by a 5-s feature-target interval, and all target stimulus pr...
Expression of flavor preference depends on type of test and on recent drinking history [0.03%]

The persistence of a conditioned flavor preference was examined in 3 experiments. All contained an initial acquisition phase in which half the rats were given almond odor mixed with sucrose (AS) in some sessions and water (W) only in other ...
The role of interference produced by conflicting associations in contextual control [0.03%]

In 2 experiments, participants completed a computer task in which they judged the probability of outcomes occurring (e.g., flowers growing, a bug infestation) given cues (e.g., treatment of soil with a fictitious garden product). In each 2-...
Rapid reacquisition of fear to a completely extinguished context is replaced by transient impairment with additional extinction training [0.03%]
对完全消退的背景快速重新获得恐惧被额外的消退训练所替代引起暂时的功能损害

Hiu Tin Leung et al.
A series of experiments studied reacquisition of fear reactions to a completely extinguished context. Reacquisition was rapid when reconditioning occurred as soon as the fear reactions were completely extinguished, showing that the original...
The role of video coherence on object-based motion discriminations by pigeons [0.03%]
视频连贯性在鸽子基于对象的运动辨别中的作用

Robert G Cook
Two experiments examined the effects of video coherence on the discrimination of relative motion by pigeons using a go/no-go procedure. Pigeons were trained to discriminate video stimuli in which the camera's perspective went either "around...

Three experiments examined various facets of the perception of continuous and discontinuous line segments in pigeons. Pigeons were presented with 2 straight lines that were interrupted by a gap. In some instances, the lines were the same an...

Using a radial maze analog task, T. R. Zentall, J. N. Steirn, and P. Jackson-Smith (1990) found evidence that when a delay was interpolated early in a trial, pigeons coded locations retrospectively, but when the delay was interpolated late ...
