When do Groups Exert Influence?
The group influence on an individual's buying behaviour depends on three factors:
Attitude Towards the Group: According to William O. Bearden and
Richard Rose, individual's susceptibility to group influence varies widely.
The buying behaviour of a consumer is more likely to be influenced by the
group if the individual:
1. Views the reference group as a credible source of information about the
product or service.2. Values the views and reactions of group members with regard to buying
decisions.
3. Accepts the rewards and sanctions allotted out by the group for proper or
improper behaviour.

Nature of the Group: James H. Leigh and Terrance G. Gabel note that
reference groups are more likely to influence a group member's behaviour if they
are:
i. Cohesive, that is having similar values and norms.
ii. Frequently interacting and thus creating more opportunities to influence
members.
iii. Distinctive and exclusive, that is, the membership in the group is highly
regarded.
As is case with the Harley-Davidson group example, the group is closely knit and
for many members biking has become a full-time hobby. Membership is
exclusive and distinctive as they refer to each other as "brothers" and outsiders
as "citizens.Nature of the Product: The nature of the product also determines the degree of
influence a group has on an individual. Groups are more likely to be influential
for products, which are: (a) visible such as clothing and (b) exclusive that might
speak of status such as a Mercedes.

Types of Reference Groups
Reference groups furnish points of comparison by which one can evaluate
attitudes and behaviour. An individual can be a member of a reference group
such as the family and would be said to be part of a membership group. This
same individual may aspire to belong to a cricket club and would be said to be
apart of an aspiration group. A disclaimant group is one to which an individual
may belong to or join and then reject the group's values. An individual may also
regard the membership in a specific group as something undesirable and to be
avoided. Such a group is a dissociative group.

Aspiration Groups
Anticipatory Aspiration Groups:
These are groups that an individual
anticipates to join at some future
time. The individual, generally, has
some direct contact with such
group(s).For instance, the individual may
wish to join a group higher in the
organisational hierarchy.
The ad appeal focuses on
anticipation of ultimately reaching
at the top in the business
organisation.

Nature of Reference Groups
Reference groups establish certain norms, roles, status,socialisation and power. These characteristics exert theirinfluence on consumers.
Norms: - 'Norms' are generally defined rules and
standards of behaviours that the group establishes. 'Values' are shared beliefs among group members
regarding what behaviours are appropriate orinappropriate. Cultures and sub-cultures largely define
the values. 'Roles' refer to functions that an individual assumes or
that the group assigns to her/him to accomplish groupobjectives.

Nature of Reference Groups
'Status' is the achieved or ascribed position that theindividual occupies within the group's hierarchy. Asone may expect, greater power and influence goes withhigher status.
'Socialisation' refers to the process by which new
members learn the group's system of values, normsand expected behaviour patterns.
Power A groups influence on its members behaviour isclosely related to its power.

Relative Importance of Informational, Comparative
and Normative Influence
Product Characteristics: - Consumers tend to be susceptible toinformational influence when products are technologically complexsuch as computers and peripherals, autos, air conditioners andwashing machine etc.
Researchers have hypothesised that reference groups can influencetwo types of decisions: (1) whether we buy a product within a givenproduct category and (2) what brand we buy. The influence wouldalso depend on whether the product is typically consumed in privateor public and whether it is a necessity or luxury.
For example, the group will probably not influence whether amember buys Colgate toothpaste or Aquafresh. But the group mightinfluence the purchase of products such as a brand of latest mobilephone, or watch.

Relative Importance of Informational, Comparative
and Normative Influence
Consumer Characteristics: - Some consumer personalities aresuch that make them readily susceptible to influence by others.
Those susceptible to interpersonal influence seek to enhance theirself-image by possessing products that they believe others will
approve of.
A personality characteristic referred to as "attention to socialcomparison information" (ATSCI) is also related to normativeinfluence. Those individuals who are high on this personality trait are
likely to pay a great deal of attention to what others do and use thisinformation as a guide to their own behaviour.

Marketing Strategies Based on Reference Group Influence
Marketers employ informational, comparative and normative group
influences to develop marketing communication strategies. Advertising often makes use of informational influence through
expert spokespersons who communicate information about productfeatures and performance.
Using Persons like Amitabh Bachan to prove to audience thatNavrattan Oil is the best, Binani Cement is the best as peoplebelieve him to be a credible authority.
Advertising applies comparative influence by using either an actualreferent in the form of a typical consumer or use a celebrity as a
symbolic referent with whom consumers identify because she/he islikeable or attractive. The typical consumer (Lalitaji of Surf ad)persuades consumers that people like themselves have used theadvertised product.
The ad for Fiat Palio uses Sachin Tendulkar as a symbolic referent.

Marketing Strategies Based on Reference Group Influence
Marketers frequently use normative influence approach by showing
group approval in ads for a particular brand. Commercials of OrientPSPO, Coca Cola, Pepsi, Taj Mahal tea, brands of paints, clothingand personal care products etc. are examples of advertising ssimulation of social approval.
Celebrities are best used as experts when consumers view them as
knowledgeable about the product category and conveying legitimacyin their message.

Word-of-mouth Communications
Word-of-mouth is interpersonal communication that takes place between two or
individuals such as members of a family or reference group. All of these people
exert an influence on the consumers' purchase behaviour through such
communications. The saying "a satisfied customer is your best salesperson"
shows the importance of favourable word-of-mouth to the marketer, because
satisfied customers influence relatives and friends to buy the product.
Consumers learn about new products or service and retail outlets etc., from
family members, friends and other reference groups in two ways:
1. By observing or participating with them as they consume a product orservice.
2. By asking for information or advice about a product or service from them.

Conditions for Word-of-mouth Communication
Research study by Herr, Kardes and Kim has shown that word-of-mouth is not
the dominant influence in each situation. For example, they found that word-of-
mouth is not important in the evaluation of an automobile if (1) consumers
already have strong impression of the product and/or (2) negative information
about the product is available.
1. The product is visible and, thus, purchase behaviour becomes obvious.2. The product is distinctive and reflects a particular style, taste and other
personal norms.
3. The product is new and consumers have not established impressions and
attitudes about it.
4. The product conforms to important group norms and belief systems such asreactions to a new soft drink, or teenagers' reactions to pop and rock music.
5. Consumers perceive the purchase of the product as risky and, due to this
reason, are more likely to discuss about it and seek information and advice
from friends and relatives.

Word-of-mouth Communication Process
Two-step Communication Flow
Elihu Katz and Paul F. Lazarsfeld were among the first to identify and describe
word-of-mouth communication. According to them, it is two-step flow of
information : (1) from the mass media to opinion leaders and (2) from opinion
leaders to their followers. They believed that opinion leaders' exposure to mass
media is greater than that of followers.

24/66
Multi-step Communication Flow
1. Followers may not be active seekers of information; yet they are not totally
passive and may deliberately initiate requests for information. They may
also pay attention to unsolicited opinion of others.
2. Opinion leaders are also likely to receive information from followers and
may be influenced by their word-of-mouth. So, word-of-mouth frequently
turns out to be a two-directional flow of communication between leaders and
followers.
3. Mass media is not restricted only to opinion leaders. They are not the only
ones who receive all the communications. Followers too are exposed tomass media advertising and are influenced by it. Realisation of this fact led
Katz and Lazarsfeld to think that there may be others who function as
"information gatherers" or "gatekeepers," serving this function.

Characteristics of Opinion Leaders
Much research has been conducted to identify traits of opinion leaders but so far
the research is inconclusive. Despite difficulties in identifying opinion leaders,
some general traits have been identified.
1. The most salient characteristic of opinion leaders is their greater long-term
involvement with the product category compared to non-opinion leaders in
the group. This trait is referred as enduring involvement and according to G.
M. Rose, L. R. Kahle and A. Shoham, it leads to enhanced knowledge about
the product and experience with the product category or activity. This
enhanced knowledge and experience makes opinion leadership possible.
2. Opinion leadership functions primarily through interpersonal
communications and observations. These activities occur most frequently
among individuals with roughly the same social-class position as non-
leaders but opinion leaders are likely to be viewed as having higher status in
their social-class. It is important to note the significant role family members
play in opinion leadership.
8/4/2019 Group+Influences+Consumer+Buyer+Behavior+and+Different+Buyer+Behaviors Session4 Dated+29!11!09 (1)
35/66
3. Opinion leaders tend to be more gregarious and are willing to act differently
even if it attracts the attention of peers. Their exposure to mass media,
relevant to their interest, is greater. For example, opinion leaders to ladies
fashions could be expected to have greater exposure to magazines such as
Femina, Vogue and Women's Era etc. Exposure to interest relevant mass
media helps enhance their potential as opinion leaders.

Marketing Implications
An obvious fact is that consumers talk to other consumers about their personal
experiences with products, services and retail stores. Therefore, it is extremely
important that marketers pay serious attention to product quality and service and
meet or exceed consumer expectations with regard to their products or services.
The firm must make arrangements to respond to customer complaints quickly
and fairly.
Stimulating opinion leadership involves having an acknowledged opinion leader.
For example, the print ad of Colgate Total toothpaste says, "Approved byindependent dental associations in 30 countries."

Emergency problems are possible but are unexpected
and necessarily need immediate solutions. For
example, say a consumer meets an accident while onhis/her way to office, gets injured and the vehicle is
badly damaged. In such an emergency, she/he needs
a quick solution to reach hospital's emergency room.
Subsequently, she/he may plan to get the vehicle
repaired or buy a new one.

Approaches to Activating Problem
Recognition
1. Generic problem recognition focuses on
helping consumers feel a discrepancy that a
number of brands within a product category can
reduce. Generally, a marketer will use this
approach when the problem is either latent or of
low importance and one of the following
conditions exists.
i. Product is in the early stage of its life cycle.
ii. The marketer has very high market share.iii. After problem recognition, consumers'
external search tends to be limited.
iv. It is a situation of industry-wide cooperative
effort.

2. Selective problem recognition

Nature of Information SearchExtended decision-making represents a significantly more involving purchase
situation. External information can refer to any of the following:
1. The opinions, beliefs, attitudes, behaviours and feelings of relatives, friends,
neighbours and strangers contacted on the Internet.2. Professional information contained in handouts, pamphlets, articles, magazines,
the Internet and provided by personal professional contacts.
3. Direct experiences with product through trial, or inspection.
4. Marketer-initiated info included in advertisements, and by sales personnel.
Consumer decision-making requires three types of information:
1. The Evaluative Criteria : An important objective of internal and external
search for information is the determination of appropriate evaluative criteria.

2. Appropriate Alternatives
Once the consumer has established the evaluative criteria, she/he probably
starts searching for the appropriate alternative which could be brands or perhaps
stores. As a result of internal search or inquiry, the consumer may recall or learn
that the available brands of computers include IBM, Compaq, Dell, Wipro,Zenith, Vintron and Apple.

3. Attributes of Alternative
Consumers compare brands in the evoked set to make their choice. This
process of evaluation requires consumers to collect information about each
brand on each relevant evaluative criterion. In case of computer purchase, the
consumer might collect information about the price, processor, memory, graphic
card, monitor, accompanying software and warranty etc., for each brand.

Capture Strategy
The marketer's objective should be to capture a large
share of consumers' purchases.
Intercept Strategy
Intercept strategy is also related to consumers' limited
decision-making approach. If the marketer's brand is
not part of the evoked set of target market, the
appropriate strategy is to intercept consumers during
their information search on the brands in evoked set.
Preference StrategyPreference strategy is appropriate when the brand ispart of the evoked set of consumers in the targetmarket and the approach to decision-making involvesextensive information search.
Acceptance Strategy
The basic objective of the marketer is to move the
brand in theevoked set of consumers, rather than try
to "sell" the brand.

Post-Purchase Evaluation
Cognitive dissonance occurs as a result of some discrepancybetween a consumer's prior evaluation and the purchase decision.The dissonance theory was derived from two basic principles:(1) dissonance is unpleasant and will motivate the person toreduce it and (2) individuals experiencing dissonance will avoid
situations that produce more dissonance.
The probability that a consumer will experience dissonance and themagnitude of such dissonance, is a function of the following factors:
The degree of irrevocability of the decision
The importance of decision to the consumer
The difficulty of choosing among the alternatives
The individual's tendency to experience anxiety

The consumers may use one or more of
the following approaches to minimising
the dissonance:
1. Increase the desirability of the brand
purchased
2. Decrease the desirability of alternatives
not selected
3. Decrease the importance of the purchase
decision
4. Return the product before using it.
After purchase, customers are more
receptive to reinforcing advertisements

Extensive Problem Solving A lot of information needed
Must establish a set of criteria for evaluation
Limited Problem Solving
Criteria for evaluation established Fine tuning with additional information
Routinized Response Behavior
Usually review what they already know. There are
some products which are used on a daily basislike food items, soap, shampoo etc. For theseproducts purchase is routinised. Command LowInvolvement

Levels of Consumer Decision Making
Purchase Involvement is the level of concern for, or interest
in, the purchase process stimulated by the need to consider acertain purchase.
Product involvementrefers to a consumers level of interestin a certain product. Marketers communicate many sales
promotions to increase consumer involvement in a product. Advertising involvementrefers to the consumers interest in
processing the ad messages. Television is said to be a lowinvolvement medium and consumers process information in apassive manner. In contrast, print is a high-involvement
medium as the readers actively process information. Purchase situation involvementmay occur while buying the
same item in different contexts.

Nominal Decision-making
At one end of choice continuum is nominal decision-making, also
referred to as nominal problem solving, habitual decision making, orroutine problem solving. Nominal decision-making is generally theoutcome of continued satisfaction with a brand which was initiallychosen after an extended decision-making process, or the consumerdoes not attach much importance to the product category orpurchase.

Limited Decision-Making
Limited decision-making is usually more straightforward and simple. It involves
internal (long-term memory) and limited external search, consideration of just a few
alternatives, simple decision rules on a few attributes and little post-purchase
evaluation. As pointed out earlier, it covers the middle ground between nominal and
extended decision-making. Buyers are not as motivated to search for information, or
evaluate each attribute enthusiastically, but actually use cognitive shortcuts. According
to Wayne D. Hoyer, when the level of consumer involvement is lowest, limited
decision-making may not be much different than nominal decision-making. For
example, while in a store, the consumer notices a point-of-purchase display of
Nescafe and picks up one pack based on her/his memory that its aroma and taste is
good. If the consumer's decision rule is to buy the cheapest brand of instant coffee
available, she/he looks at different brands of coffee for prices and buys the least
priced brand. Sometimes, emotional factors may influence limited decision-making.

Extended Decision-Making
Consumer purchases involving extended decision-making correspond most closely to
the traditional decision-making perspective. Such decisions involve extensive internal
(long-term memory) and external (outside sources) information search followed by a
rigorous evaluation of several alternatives because consumers do not possess any
meaningful information about the product or service and need much of it. The
evaluation often involves careful consideration of attributes of one brand at a time
and taking stock of how the attributes of each brand measure up to a set of desiredcharacteristics. All this happens in response to a high level of consumer's
involvement in making a purchase decision. Such complex decisions are relatively
few and may relate to buying a computer, stereo system, washing machine, laser
printer, or a new house etc. Post purchase evaluation is more likely to be complex
and dissonance causing.
