ATTITUDE FORMATION AND CHANGE 81
processing, but an evaluation based on simple, peripheral cues, such as background music,
humour, an attractive source or endorser, the number of arguments used, etc.^21 In other
words, a favourable brand attitude might be formed because the consumer liked the music
in a Levi’s commercial or the erotic setting in a Häagen-Dazs ad or because the consumer is
fond of the polar bears in the Coca-Cola commercial, or because he or she assumed that
the high price of the Miele washing machine is a sign of superior quality, or that French wine
is invariably good. However, such attitudes do not necessarily last long. If Pepsi launches
a campaign with a cute animal, a celebrity or a nice song, consumers may forget about
Coca-Cola’s nice polar bears and switch their attitude in favour of Pepsi. The reason why
consumers start paying more attention to peripheral cues is that in many ads peripheral cues
form the only processable information under circumstances of low motivation, limited ability
or limited opportunity. Ads without attractive peripheral cues, but with an easy-to-process,
product-related message, might also work under low MAO, simply because the cognitive
resources to form counter-arguments are lacking.
Probability markers are specific words or phrases in advertising used to signal to what degree it is likely that a given
claim or argument is true. Those markers that indicate the probable, rather than absolute, truth of a claim are known
as hedges, whereas the markers that indicate complete commitment to the truthfulness of the claim are known as
pledges. Hedges, which can be adverbs (‘possibly’, ‘probably’), verbs (‘can’, ‘may’, ‘help’), particles (‘about’, ‘sort
of ’), or other expressions (‘9 out of 10’, ‘85% of ’, etc.), weaken the impact of a claim by allowing for exceptions or
avoiding total commitment. Pledges, on the other hand, examples of which also include some adverbs (‘definitely’,
‘undoubtedly’), verbs (‘will’, ‘guarantee’), and other expressions (‘have been proven to’, ‘you can be sure’), are
absolute in nature and signal total confidence in the truthfulness of the claim.^22 Probability markers are frequently
used in advertising.^23 Some well-known examples include the Carlsberg campaign (‘Probably the best beer in the
world’), a similar slogan used by a Belgian brand of beer, Delirium Tremens (‘Voted as best beer in the world’),
numerous drug advertisements (such as a Nutra-Life ad stating ‘Nutra-Life Cold and Flu fighter may reduce the
severity and duration of colds’), as well as cosmetics ads (such as an Oil of Olay ad stating ‘Proven to help you look
revitalised’).
A study was conducted with 331 Belgian and 374 Croatian students;^24 55.7% of the participants were female.
The majority of them (45.9%) were between the ages of 22 and 26. The remainder fell into the following age
groups: 33.1% between the ages of 18 and 21; 6.7% between the ages of 27 and 30; 12.4% under 18; and 1.9%
over 30. The purpose of the study was to assess to what extent the type of service (hedonic vs utilitarian), the
involvement with the service (high vs low), the type of probability marker (hedge, pledge and none), and tolerance
for ambiguity affected consumer responses.
Language power, just like emotions, has been empirically proven to act as a peripheral cue.^25 It is, therefore, likely
that involvement would act as a moderator to the effectiveness of the usage of probability markers in advertising,
namely that the impact of probability markers on advertising effectiveness would be greater in low-involvement
situations than in those where involvement is high. This assumption finds support in a previous study.^26
Hedonic services, often also referred to as experiential services, are characterised by high levels of people
orientation, employee contact and customisation. The quality of and satisfaction with a hedonic service rely on the
sensations derived from the consumption of the service,^27 and are highly person-specific. As such, they are hard to
assess objectively, being dependent on personal, subjective tastes and experiences. Using pledges, markers of
researCh insight
Probability markers have a different effect depending on the type of service and the
tolerance for ambiguity of individual consumers
