Exhibit 5-10 This ad contains peripheral cues, most notably a celebrity endorser

and the ad's ability to persuade the receiver depends primarily on the receiver's evaluation of the quality of the arguments presented. Predominantly favorable cognitive responses (support arguments and source bolsters) lead to favorable changes in cognitive structure, which lead to positive attitude change, or persuasion.

Conversely, if the cognitive processing is predominantly unfavorable and results in counterarguments and/or source derogations, the changes in cognitive structure are unfavorable and boomerang, or result in negative attitude change. Attitude change that occurs through central processing is relatively enduring and should resist subsequent efforts to change it.

Under the peripheral route to persuasion, shown on the right side of Figure 5-9, the receiver is viewed as lacking the motivation or ability to process information and is not likely to engage in detailed cognitive processing. Rather than evaluating the information presented in the message, the receiver relies on peripheral cues that may be incidental to the main arguments. The receiver's reaction to the message depends on how he or she evaluates these peripheral cues.

The consumer may use several types of peripheral cues or cognitive shortcuts rather than carefully evaluating the message arguments presented in an advertisement.33 Favorable attitudes may be formed if the endorser in the ad is viewed as an expert or is attractive and/or likable or if the consumer likes certain executional aspects of the ad such as the way it is made, the music, or the imagery. Notice how the ad in Exhibit 5-10 for Maxfli golf balls contains several positive peripheral cues, including a popular celebrity endorser (golfer Fred Couples) and excellent visual imagery. These cues might help consumers form a positive attitude toward the brand even if they do not process the message portion of the ad.

Peripheral cues can also lead to rejection of a message. For example, ads that advocate extreme positions, use endorsers who are not well liked or have credibility problems, or are not executed well (such as low-budget ads for local retailers) may be rejected without any consideration of their information or message arguments. As shown in Figure 5-9, the ELM views attitudes resulting from peripheral processing as temporary. So favorable attitudes must be maintained by continual exposure to the peripheral cues, such as through repetitive advertising.

Implications of the ELM The elaboration likelihood model has important implications for marketing communications, particularly with respect to involvement. For example, if the involvement level of consumers in the target audience is high, an ad or sales presentation should contain strong arguments that are difficult for the message recipient to refute or counterargue. If the involvement level of the target audience is low, peripheral cues may be more important than detailed message arguments.

An interesting test of the ELM showed that the effectiveness of a celebrity endorser in an ad depends on the receiver's involvement level.34 When involvement was low, a celebrity endorser had a significant effect on attitudes. When the receiver's involvement was high, however, the use of a celebrity had no effect on brand attitudes; the quality of the arguments used in the ad was more important.

The explanation given for these findings was that a celebrity may serve as a peripheral cue in the low-involvement situation, allowing the receiver to develop favorable attitudes based on feelings toward the source rather than engaging in extensive processing of the message. A highly involved consumer, however, engages in more detailed central processing of the message content. The quality of the message claims becomes more important than the identity of the endorser.

The ELM suggests that the most effective type of message depends on the route to persuasion the consumer follows. Many marketers recognize that involvement levels are low for their product categories and consumers are not motivated to process advertising messages in any detail. That's why marketers of low-involvement products often rely on creative tactics that emphasize peripheral cues and use repetitive advertising to create and maintain favorable attitudes toward their brand.

Summarizing the Response Process and the Effects of Advertising

As you have seen from our analysis of the receiver, the process consumers go through in responding to marketing communications can be viewed from a number of perspectives. Vakratsas and

Ambler recently reviewed more than 250 journal articles and books in an effort to better understand how advertising works and affects the consumer.35 On the basis of their review of these studies, they concluded that although effects hierarchies have been actively employed for nearly 100 years, there is little support for the concept of a hierarchy of effects in the sense of temporal sequence. They note that in trying to understand the response process and the manner in which advertising works, there are three critical intermediate effects between advertising and purchase (Figure 5-10). These include cognition, the "thinking" dimension of a person's response; affect, the "feeling" dimension; and experience, which is a feedback dimension based on the outcomes of product purchasing and usage. They conclude that individual responses to advertising are mediated or filtered by factors such as motivation and ability to process information, which can radically alter or change the individual's response to advertising. They suggest that the effects of advertising should be evaluated using these three dimensions, with some intermediate variables being more important than others, depending on factors such as the product category, stage of the product life cycle, target audience, competition, and impact of other marketing-mix components.

Other researchers have been critical of the hierarchy models as well. For example, Hall argues that advertisers need to move away from explicit and implicit reliance on hierarchical models of advertising effects and develop models that place affect and experience at the center of the advertising process.36 The implication of these criticisms is that marketers should focus on cognition, affect, and experience as critical variables that advertising may affect. However, they should not assume a particular sequence of responses but, rather, engage in research and analysis to better understand how advertising and other forms of promotion may affect these intermediate variables in various product/market situations.

Those responsible for planning the IMC program need to learn as much as possible about their target audience and how it may respond to advertising, along with other forms of marketing communication. For example, William Weilbacher has noted that
