Observations : Advertising to Increase Effectiveness of Use
研究发现，精心设计的广告能让消费者更相信产品效果，从而在使用时更努力，最终提升产品的实际效果。
When a well-executed advertising message creates a believer in the effectiveness of the sponsor's product, that believer may be motivated to “try harder” in using the product to achieve desired results. If in fact the advertising precipitates extra effort and if that extra effort actually contributes to product effectiveness, the advertising that precipitated it has added significantly to how effective the product actually will be.
