| Abstract: | Consumers unfamiliar with passion-fruit juice were presented with 24 computer generated package images on which six packaging factors (background color, picture, information, brand, language and shape) had been manipulated and asked to give scores for six expected sensory attributes (sweetness, pureness, sharpness, refreshing, freshness, naturalness) and liking. Significant effects were obtained for each attribute, with background color and information being the most important. Consumers varying in Need For Cognition (NFC) were affected differently by the investigated features of the package. High NFC individuals used less of the packaging factors than low NFC subjects did. |
