Cue properties vs palatability of flavors in avoidance learning
TLDR
When a flavor is immediately followed by peripheral electric shock, rats learn to use the flavor cue to avoid shock, but ingestion of that flavor is not reduced outside the shock apparatus as discussed by the authors.Abstract:
When a flavor is immediately followed by peripheral electric shock, rats learn to use the flavor cue to avoid shock, but ingestion of that flavor is not reduced outside the shock apparatus. In contrast, when a flavor is followed by internal illness, rats will reject that fluid in or out of the situation where illness occurred. However, motor approach to visual cues previously associated with that flavor is not immediately affected. Thus flavor, used as a cue, acquires generalization properties depending upon the subsequent reinforcer and reflecting differential specialization in mechanisms controlling palatability and locomotor responses.read more

On the generality of the laws of learning
TL;DR: A review of data from the traditional learning paradigms shows that the assumption of equivalent associability is false: in classical conditioning, rats are prepared to associate tastes with illness even over very long delays of reinforcement, but are contraprepared to associated tastes with footshock.

Phobias and preparedness
TL;DR: An analysis of phobias using a more contemporary model of fear conditioning is proposed, and a reconstruction of the notion of symbolism is suggested.

TL;DR: The chapter discusses the multiple determinants of food selection in man that are divided into biological factors and effects of individual experience, on one hand, and cultural influences, on the other.

Learned taste aversions in rats as a function of dosage, concentration, and route of administration of LiCl.

TL;DR: It was concluded that the rat is highly sensitive to learning a taste aversion with LiCl and that the threshold dose for producing an aversion is approximately 0.15 mEq/kg.

Relation of cue to consequence in avoidance learning
John Garcia,Robert A. Koelling +1 more
TL;DR: An audiovisual stimulus was made contingent upon the rat’s licking at the water spout, thus making it analogous with a gustatory stimulus, which apparently stimuli are selected as cues dependent upon the nature of the subsequent reinforcer.

Learning with prolonged delay of reinforcement
TL;DR: Gustatory aversions, induced in rats by conditionally pairing a distinctive flavor with a noxious drug, were readily established even when injections were delayed an hour or more, suggesting a function of the specific effects of the reinforcer on the organism.

Cues: their relative effectiveness as a function of the reinforcer.
TL;DR: Two cues, either size or flavor of food pellet, were conditionally paired with either malaise induced by x-ray or pain induced by shock in four groups of rats and the combination of flavor and illness produced as conditioned decrement in consumption, but that of size and illness did not.

TL;DR: An aversion to saccharin flavored water (.1%) was conditioned in male albino rats using X-rays as the noxious stimulus and it was noted that an aversion could be formed when these stimuli were separated by as much as 12 h.
