Investigating the Effect of Physiological Need States on Palatability and Motivation Using Microstructural Analysis of Licking
2020, NeuroscienceCitation Excerpt :The reason for the discrepancy between these two studies with respect to the effect of food deprivation on cluster size remains unclear but may reflect methodological differences including length of deprivation (17 h in Grill and Norgren, 1978; 23 h in Spector, et al., 1998), test duration (30 or 60 min) or choice of pause criterion. In a study of successive negative contrast, Grigson et al. (1993) performed microstructural analysis when food-deprived and free-feeding rats were given 5-min access to either 0.1 M or 1.0 M sucrose solution. Although they did not explicitly compare effects between deprivation conditions, visual inspection of their data strongly suggests that food deprivation increased cluster size for the high but not low concentration of sucrose without affecting number of clusters.
Consummatory successive negative contrast in rats: Assessment through orofacial taste reactivity responses
2018, Learning and MotivationCitation Excerpt :The latter is expressed in subsequent trials in which the animal experiences a conflict caused by the anticipation of the expected reinforcement and the frustration associated with the devalued reward. Overall, the results reported here and the background reported by Suárez et al. (2013) and Grigson et al. (1993) form a body of evidence consistent with Amsel's frustration theory. If the initial suppression of the response to reward devaluation was due only to the animals’ detection of change and searching behaviors, no variations in affective or hedonic parameters should be observed in the first trial.
Susceptibility to traumatic stress sensitizes the dopaminergic response to cocaine and increases motivation for cocaine
2017, NeuropharmacologyCitation Excerpt :Rats were acclimated to two drip resistant water bottles for a total of 3 days prior to segregation testing. Following segregation, the water in one of the bottles was replaced with a 0.25% sucrose solution for the first 48 h and then a 1% sucrose solution for the next 48 h in order to prevent a negative contrast effect (Grigson et al., 1993). Rats were allowed equal access to the sucrose and water bottles for the entirety of the testing period.
Memory-dependent effects on palatability in mice
2016, Physiology and BehaviorCitation Excerpt :Both groups were then allowed to consume 4% sucrose. In rats it has been demonstrated that the shift from a high concentration of sucrose to a low concentration results in a reduction in palatability of the low concentration of sucrose compared to a condition in which animals only experience the low concentration of sucrose [12]. In mice there are reports of negative contrast effects on levels of consumption (i.e., a shift from high to low concentration of sucrose results in reduced intake compared to controls, [19]), but there are few reports of an effect on palatability (see [1]).
