“…Lavin et al (1980) originally suggested this possibility, although they called the PPE a "transferred" flavor aversion. However, Coombes et al (1980) and the present Experiment 1 showed that the PPE was not affected by whether the PP had a flavor aversion to transfer. An important similarity between the PP as a US and sickness itself as a US is that both can produce flavor aversions if presented as much as 6 h after consumption of a flavored solution ; the only other USs known to be effective over such long delays are toxins.…”

“…In Experiment I, Group UP/Sac-nPP exhibited a saccharin preference ratio of .14 on the first test while the 6O-mg LiCl PP group in Experiment 2 exhibited a corresponding saccharin preference ratio of .29; in both cases, the control level was .38. The effects obtained by Coombes et al (1980) in their experiment with .60/0 saccharin were even larger than those in Experiment 1. Nevertheless, the PPE was replicated in the present Experiment 2.…”

“…This was whether the PP was allowed to develop an aversion to saccharin solution on the day of conditioning by being administered saccharin solution prior to being placed with the subject rat. Coombes et al (1980) found that this factor did not affect the magnitude of the PPE. If so, the PPE does not depend on the development of a saccharin aversion in the PP, and hence the PPE cannot be considered transfer of a learned aversion from the PP to the subject rat.…”

“…An unpoisoned rat that drinks saccharin solution and is subjected to the presence of a poisoned rat in its home cage as much as 6 h later will develop a saccharin aversion (Coombes, Revusky, & Lett, 1980;Lavin, Freise, & Coombes, 1980). The poisoned rat is called a poisoned partner (PP) and the aversion exhibited by the unpoisoned subject rat is called the PP effect (PPE).…”

If an unpoisoned rat drinks a flavored solution and then is exposed to another rat suffering from lithium poisoning, the unpoisoned rat will later exhibit a flavor aversion. This is called the poisoned partner effect (PPE). The present experiments showed that (1) the US preexposure effect applies to the PPE since, if the unpoisoned rat is preexposed to poisoned partners, the PPE is attenuated, (2) the magnitude of the PPE increases with the dose of poison, and (3) a poisoned partner accustomed to poisoning produces a slightly weaker PPE than a partner naive to poisoning, Two earlier findings were confirmed: (1) The PPE occurs because the poisoned partner is an aversive US, not because a learned aversion is transferred from one rat to another; and (2) the PPE is weaker than an aversion produced by poisoning itself.

Two experiments investigated the ability of preweanling rats, 4 or 8 days of age, to form an odor-LiCl association across various CS-US delays. The results of the odor preference test indicated that 8-day-old subjects acquired an aversion to the CS+ odor when trained with either a 0 or 15 min CS-US delay, while 4-day-old subjects did not exhibit a reduction in preference for the CS+ at any of the CS-US delays tested. The absence of a reduction in preference for the CS+ by 4-day-old rats could not be attributed to their failure to acquire the odor aversion, however; they avoided a texture with which the CS+ odor was paired in a second order conditioning paradigm. The results suggest that outcomes appearing to represent age-related differences in associative learning may in some instances be more appropriately viewed as representing ontogenetic differences in the way in which acquired associations are manifested in behavior.

Acute prenatal experience with alcohol in the amniotic fluid: Interactions with aversive and appetitive alcohol orosensory learning in the rat pup

Prenatal alcohol acute contamination of the amniotic fluid and different postnatal manipulations with this drug alter subsequent responsiveness to EtOH's chemosensory cues. In this study, the interaction between prenatal and postnatal alcohol-related experiences was examined. Alcohol administered in the amniotic fluid during gestational Day 21 potentiated subsequent alcohol-odor conditioned preferences resulting from postnatal pairings between the odor and sucrose intraoral infusions. No interaction was attained when examining the impact of the in utero experience with postnatal aversive conditioning defined by alcohol odor-citric acid pairings (Exps. 1a & 1b). In Exp. 2, infantile alcohol aversions derived from a state of acute ethanol intoxication were inhibited by prior alcohol experience in utero. Examination of alcohol levels in fetal trunk blood and the amniotic fluid suggests that the antenatal experience is related to the chemosensory perception of the drug rather than its intoxicating properties (Exp. 3). These results strongly suggest that the alcohol-related memory generated proximal to birth can modulate subsequent learning with the drug.
