Learned taste aversions in children receiving chemotherapy.

Taste aversions to mother's milk: the age-related role of nursing in acquisition and expression of a learned association.

The development of taste aversion learning to novel cues contained in mother's milk was examined in rat pups. Pups receiving distinctive mild by experimenter-delivered oral infusions followed by toxicosis formed an aversion to the dam's diet. Robust aversions were learned as early as Day 10 and were retained for at least 11 days. When the same distinctive milk was obtained directly from a foste...

Targets of learned food aversions in humans.

In order to determine whether some nutrients are more salient targets than others for the development of learned taste aversions a large group of normal human subjects were surveyed about their experiences with such aversions. The targets of these spontaneously occurring food aversions were identified and classified into general food categories. A prominent category for human aversions proved t...

"Learned safety" as a mechanism in long-delay taste-aversion learning in rats.

Rats learn taste aversions with unusually long CS-US delays. This has previously been explained as slow decay of a CS trace or as relative lack of interference. We propose, however, that the CS-US delay gradient is a learning curve: During the delay, a rat gradually learns that a taste is "safe." A solution which a rat drinks only once becomes safe and resistant to learned aversions for at leas...

Food aversions in children receiving chemotherapy for cancer.

Ontogeny of long-term memory for learned taste aversions.

Eighteen-day-old and adult rats were trained on a learned taste-aversion (illness reinforced) or a lick-suppression (shock reinforced) task and tested for retention after either 1, 28, or 56 days. Young rats showed a retention deficit relative to adults in the lick-suppression task but not for taste-aversion learning. Young rats did, however, show relatively less suppression to the saline solut...
