It can be unnerving or frustrating to have a meal with someone who refuses to eat. Garcia proposed that the sweetened water became regarded negatively because of the nausea inducing effects of the radiation, and so began the study of conditioned taste aversion. [4] The diet of common vampire bats only consists of vertebrate blood and therefore it is hypothesized that the development of a taste aversion to their only food source would not be advantageous for these animals.[4]. Behavior modification has been proven useful in helping people with severe mental retardation A lack of reaction following the consumption of this food points to a psychological cause.
