Data sets from three studies were examined to determine the effects of brand identification and package design on consumer responses during product evaluation. In these studies, consumers evaluated products with or without brand identification, compared products in standardized conditions, and compared products in different package designs with different or identical product contents. Measurement of consumer responses for all studies was based on 9-point hedonic scale. The results of the study showed that consumers were less critical in their evaluation when the samples being assessed were identified by brand names. Brand identification and package design, when not concealed in the comparison of product contents, resulted in consumer response bias. Also, the popularity of a brand influenced consumer's perception of products. 相似文献

The Dufour gland epithelium in Aenictus has a crenellate appearance, a condition previously found only in the primarily African genus Dorylus . This character, taken alone, strongly suggests that these two genera share a common ancestry, as is presently reflected in their placement in the subfamily Dorylinae, and that an independent, convergent origin for them, as has been proposed in the triphyletic hypothesis for army ant evolution, is incorrect. 相似文献

Iterative evolution of Middle Jurassic ammonite faunas 总被引:2,自引:0,他引:2

The phenomenon of iterative evolution of homeomorphs in identical temporal sequences is exhibited by Aalenian and Bajocian ammonite faunas in the south German depositional basin. Within each evolutionary cycle, inflated, evolute, and ornamented shells with complex suture lines are successively replaced with discoidal, involute, smooth shells with simpler sutures. Three distinct and identical cycles of morphological change occur, and involve ammonites belonging to four different familial/subfamilial groups: the Leioceratinae, Graphoceratinae, Hammatoceratidae, and Sonniniidae. Geometric and statistical analyses of morphological change within each of these higher taxa reveal remarkable iteration in both the pattern and proportion of change with time. The iterative morphological cycles were not driven by orthogenesis or anagenetic transformation within lineages, as has been previously suggested. A clear correlation exists between the successive ammonite faunas and repeated cyclical changes in the physical marine environment of the depositional basin.
