Abstract :
  The present study examined laypersons' judgment of dose-response relationship. Two hundred and sixty-one college students participated in a 'before-after design' experiment. Results suggested that more than 70% subjects chose the sigmoidal curve model as the dose response relationship of pesticide; whereas after watching a five-minute TV program which reported using the pesticide in orange juice products, about a half of them changed their choice to the liner or the convex model. Implications of these results in risk communication were discussed.

KEY WORDS : Dose-response relationship, Risk communication, Laypersons' judgment,
