(Gregg, et al, 1978). These results provide more evidence to support taste aversion.To further test the validity of conditioned taste aversion, a study was done in the generalization of conditioned taste aversion in rats (Richardson, Williams & Riccio, 1984). This study further investigates the effects of delayed testing (2, 7, 21 days), the rats were given varying concentrations of sucrose (2.5%, 10%, 32%) and immediately received lithium chloride. Subjects were then tested either 2, 7, or 21 days after conditioning. Findings show that the rats show avoidance in all categories, this further reveals that CTA shares many similarities with the process of classical conditioning, except for the three principles mentioned earlier (Richardson, et al, 1984).A more recent experiment done on taste aversion is a study on the interval between the CS and UCS as a determiner of generalization performance (Land, Harrod & Riccio, 1998). In this experiment rats were trained in a conditioned taste aversion paradigm in order to determine whether a trace interval between the CS and the UCS would result in the forgetting of stimulus attributes. Subjects were conditioned with milk and where given either and immediate or a delayed injection of lithium chloride. They were then tested 48 hours later with either milk of chocolate milk, a generalized flavor. The rats conditioned immediately following the presentation of the milk avoided the milk more than the chocolate milk, pointing out discrimination between the two flavors. Those conditioned after a trace interval avoided both flavors equally, this may suggest that there was a loss of stimulus attributes of the original CS (milk). The delay rats however, still exhibited considerable learning when compared with the control group, which did not receive the UCS. These results once again shows the strength of effects that taste aversion can have on a subject.Although there have been many studies done in support ...
