Step 2 Persuasive Techniques

The persuasive strategies used by advertisers who want you to buy their product can be divided into three categories: pathos, logos, and ethos.

 Pathos: an appeal to emotion.

An advertisement using pathos will attempt to evoke an emotional response in the consumer.  Sometimes, it is a positive emotion such as happiness: an image of people enjoying themselves while drinking Pepsi. Other times, advertisers will use negative emotions such as pain: a person having back problems after buying the “wrong” mattress. Pathos can also include emotions such as fear and guilt: images of a starving child persuade you to send money.

 

Logos: an appeal to logic or reason.

An advertisement using logos will give you the evidence and statistics you need to fully understand what the product does. The logos of an advertisement will be the "straight facts" about the product: One glass of Florida orange juice contains 75% of your daily Vitamin C needs.

 

Ethos: an appeal to credibility or character.

An advertisement using ethos will try to convince you that the company is more reliable, honest, and credible; therefore, you should buy its product. Ethos often involves statistics from reliable experts, such as nine out of ten dentists agree that Crest is the better than any other brand or Americas dieters choose Lean Cuisine. Often, a celebrity endorses a product to lend it more credibility: Catherine Zeta-Jones makes us want to switch to T-Mobile.

The Language of Appeal

When it comes to using language, advertisers draw on a number of techniques. For example, they use language to appeal to our desire to obtain a bargain or to present a product as being a breakthrough in technology. Infomercials in particular make heavy use of the language of appeal or emotive language. You are familiar with the the ideas of ‘buy one, get one free’ or ‘order now and you will receive a bonus’. The use of words such as "new", "free", "fast", "introducing", "at last" and "easy" is the language of appeal or emotive language. 

In the 48-hour Rapid Detox commercial , the product advertised promises immediate results. Notice that modality is achieved through discriminating choices in modal verbs, adverbs, adjectives and nouns. To show a high degree of certainty about the likelihood of events, verbs of high modality are used.  As well as modal verbs, modality can be expressed through choices of nouns, adjectives, and adverbs. If we feel tentative about something, we use low modality. Refer to the following chart (adapted from Derewianka, 2005) when investigating the language of advertising and the modality used.

High modality : must   ought to   has to   definitely   certainly   always   never   requirement   obligation  obligatory  required  determined

Medium modality: will   should   can   need to    I think     probably    apparently    often    usually   necessity probable   necessary

Low modality:  may   might   could   would   possibly   perhaps   seems   appears   maybe    sometimes     possibility   probability   possible

A cosmetic ad, for example, is more likely to use language such as, ‘You will notice an immediate change’, rather than, ‘You might notice a change’; or ‘It’s a must have item’, as opposed to, ‘You might want one’. 


Think of  a product to sell. Your job is to sell it in three different ways, with three different slogans.  One slogan needs to communicate a hard sell of your product, another a medium sell and a third a soft sell. For each type of slogan choose words that communicate your attitude and opinions about your product from the corresponding list.
