“…This anticipatory contrast effect is suggested to occur because the less preferred solution is devalued by the availability of the preferred 32% solution, therefore, intake of the less preferred 2% solution will decrease in anticipation of the preferred solution. Flaherty et al (1994) have demonstrated that this effect is dependent on the magnitude of relative hedonic difference between the two substances. .…”

“…In order to examine this idea further we used a reference memory task based on the anticipation of a reward labeled as an anticipatory contrast paradigm Flaherty, Turovsky, & Krauss (1994), . Flaherty et al (1994) demonstrated that intake of a less preferred substance such as a water solution containing 2% sucrose is suppressed when the substance is followed by a preferred substance such as a water solution containing 32% sucrose.…”

Sixteen male Long-Evans rats were tested on a modified version of Flaherty et al's (1994) anticipatory contrast paradigm to assess memory for the anticipation of reward. Prior to testing each rat received either a control or quinolinic acid induced lesion of the agranular insular cortex. In the home cage, each rat was allowed to drink a water solution containing 2% sucrose for 3 min followed by a water solution containing 32% sucrose for 3 min. Across 10 days of testing, the control rats showed significantly increased anticipatory discriminability as a function of days. In contrast, rats with agranular insular cortex lesions failed to show anticipatory discriminability. The results of a preference task revealed that both groups could perceptually discriminate between a 2% and a 32% sucrose solution. The data suggest that the agranular insular cortex may be involved in the anticipation of reward.

Repeated exposures to gustatory stimuli produce habituation or positive contrast effects in perinatal rats

Adult rats exhibit a decrease in consummatory responses following repeated presentations of a taste (habituation) and an increase in consummatory responses if they experience an upward shift in the magnitude or intensity of a gustatory stimulus (e.g., sucrose or saccharin). These responses do not represent a direct sensorimotor reaction to a gustatory cue, but rather reflect a change in responding based on the memory of a previous taste. Here, we sought to determine if fetal rats could (like adults) adjust their orofacial motor responses based on a memory of recent gustatory experience. Embryonic Day 18 (E18) or Day 19 (E19) rat fetuses received oral lavage with either 0.15 or 0.30% saccharin (SAC). Subsequently, observations of orofacial movements (mouthing and licking) following oral lavage with 0.30% SAC were made 50 min later, 24 hr later, or on postnatal Day 3 (P3). Thus, some animals were in a "shifted" condition in which they first experienced a relatively low concentration of SAC and then a higher one while control rats ("nonshifted") received 0.30% SAC during both taste exposures. Fetuses exhibited evidence of both habituation (with repeated presentation of the 0.30% SAC) and positive contrast effects (PCEs) (following an upward shift in SAC concentration) when retested 50 min after their first exposure to SAC on E19. However, these animals did not exhibit PCEs 24 hr later or 5 days later (on P3). Contrast effects were not observed when the initial SAC exposure was on E18, and habituation responses were variable depending on the time interval between the taste presentations to these animals. Rats with a 5- to 6-day latency between the two taste presentations showed neither PCEs nor habituation. Our data indicate that PCEs and habituation effects emerge at different ages, and their demonstration is dependent upon the latency between the taste presentations.
