Human drug seeking may be goal directed in the sense that it is mediated by a mental representation of the drug or habitual in the sense that it is elicited by drug-paired cues directly. To test these 2 accounts, the authors assessed whethe...

Four experiments explored signal timing in human conditioned avoidance. Participants received discrimination training with different duration signals that announced the outcome (S+) or not (S-). Temporal discrimination and superposition of ...

In 3 experiments, the authors investigated the effect of stimulus duration on overshadowing. Experiments 1 and 2 examined responding to a target conditioned stimulus (CS1) when it was conditioned in compound with a coterminating overshadowi...
Escape from fear: a detailed behavioral analysis of two atypical responses reinforced by CS termination [0.03%]
由CS终止诱发的两种非典型逃避行为的强化机制及行为分析

Escape from fear (EFF) is a controversial paradigm according to which animals learn to actively escape a fear-eliciting conditioned stimulus (CS) if the escape response (R-sub(e)) is paired with CS termination. Some theories posit that EFF ...
Degraded contingency revisited: posttraining extinction of a cover stimulus attenuates a target cue's behavioral control [0.03%]
降级的备择方案再探：训练后的消退削弱了目标线索的行为控制作用

In a Pavlovian conditioning situation, unsignaled outcome presentations interspersed among cue-outcome pairings attenuate conditioned responding to the cue (i.e., the degraded contingency effect). However, if a nontarget cue signals these a...
Response rate and sensitivity to the molar feedback function relating response and reinforcement rate on VI+ schedules of reinforcement [0.03%]

In 5 experiments, the author examined rats' sensitivity to the molar feedback function relating response rate to reinforcement rate on schedules of reinforcement. These studies demonstrated that, at lower rates of responding, rats' performa...

Pigeons were trained to match the number of responses made during a production phase to the number of keylight flashes (2, 4, or 6) in a previous sample phase. In Experiment 1, there were 2 conditions in which the flashes were programmed to...

Pigeons were trained on a concurrent-chains procedure in which the initial link associated with the shorter terminal-link delay to food changed unpredictably across sessions. In the minimal-variation condition, delays were always 10 s and 2...
Processing of biological motion point-light displays by baboons (Papio papio) [0.03%]

Humans apply complex conceptual judgments to point-light displays (PLDs) representing biological motion (BM), but how animals process this kind of display remains uncertain. Four baboons (Papio papio) were trained to discriminate BM from no...
The discrimination of natural movement by budgerigars (Melopsittacus undulates) and pigeons (Columba livia) [0.03%]

Three experiments examined the ability of birds to discriminate between the actions of walking forwards and backwards as demonstrated by video clips of a human walking a dog. Experiment 1 revealed that budgerigars (Melopsittacus undulates) ...
