The relationship between susceptibility to nausea and vomiting and the possession of conditioned food aversions.

Because nausea and vomiting play an important role in the formation of conditioned food aversions, individual differences in susceptibility to nausea and vomiting may contribute to interindividual variation in conditioned food aversion acquisition. Two surveys reveal that, among female participants, self-reported motion sickness susceptibility is positively correlated with the number of conditioned food aversions possessed, but no such correlation appears among male participants.
