In 4 instrumental learning experiments, the hierarchical organization among responses (R), outcomes (O), and stimuli (S) was examined. Each experiment explored the possibility that S becomes associated with the R-O relation by providing inf...

Although the Associative Learner (AL) theory advocated by Shimp, Childers, and Hightower (1990) can simulate several features of human and nonhuman performance in free-operant situations, it fails to account for many of the findings that ar...

Rats running in a runway emit discriminable odors when encountering reward (R) or nonreward (N) goal events, and subsequent rats use these odors as discriminative stimuli to alter their approach speeds. In the present studies, a third goal ...
Element and compound matching-to-sample performance in pigeons: the roles of information load and training history [0.03%]

Pigeons were trained to match color and line orientation element or compound samples in a symbolic matching-to-sample task. In subsequent test sessions with element and compound samples, there was an initial superiority of element matching ...

Three experiments used rats as subjects to investigate the generalization of conditioned responding between stimuli as a function of the subjects' exposure to these cues prior to conditioning. Experiment 1 used a between-subjects design, fo...
Anticipation of future food: suppression and facilitation of saccharin intake depending on the delay and type of future food [0.03%]
期待未来的食物：根据未来食物的类型和延迟时间对糖精摄入产生的抑制与促进作用

G A Lucas et al.
A series of studies examined the (Sprague-Dawley) rat's tendency to suppress intake of .15% saccharin when it was followed by a second food after 4-, 16-, or 32-min delays. The second foods examined were 32% sucrose, 64% sucrose, lab chow, ...

The relation between the shuttlebox escape deficit produced by prior inescapable shock (IS) and fear during shuttlebox testing as assessed by freezing was investigated in rats. IS rats learned to escape poorly and were more fearful than eit...
Modeling signal features of escape response: effects of cessation conditioning in "learned helplessness" paradigm [0.03%]
逃逸反应的信号特征及“习得性无助”中的终止训练效应模型研究

T R Minor et al.
Six experiments examined the effects of signaling the termination of inescapable shock (cessation conditioning) or shock-free periods (backward conditioning) on later escape deficits in the learned helplessness paradigm, using rats (Sprague...
