One factor that can influence consumers is their mood(情绪) state. Mood may be described 21 a temporary and mild positive or negative feeling that is generalized and not tied to any particular circumstance. Moods should be 22 from feelings which are usually much more stronger 23 to specific circumstances, and often conscious. In one sense, the effect of a consumer’s mood can be thought of in 24 the same way as our reactions to the 25 of our friends — when our friends are happy and “up”, that tends to influence us positively, but when they are “down”, that can have a negative impact on us. 26 , consumers operating under a given mood state tend to react to stimuli(刺激因素) in a direction consistent with that mood state. Thus, for example, we should expect to see consumers in a positive mood state evaluate products in more of a 27 manner than they would when not in such a state. Moreover, mood states appear able to enhance(增强) a consumer’s memory.
Moods appear to be readily influenced by marketing 28 . For example, the rhythm(节奏), pitch, and volume of music has been shown to influence behavior such as 29 of time spent in supermarkets or intention to purchase products. In addition, advertising can influence consumer’s moods which, in 30 , are more likely to influence consumers’ reactions to products.
