Consumer Behavior– you are
what you buy…

• Consumer behavior (ppt)
• Innovation diffusion (ppt)
• Next week: Market research
• Think of a recent important purchase– briefly draw a
flowchart of the steps you recall moving through from
the awareness of need to post purchase
• What influenced you at each step?

• How do you know when to shop? What are the
triggers that initiate an awareness & search?
• What are the internal & external sources of these
(or create) an imbalance
between present status
and preferred state
• When a current product isn’t
• When the consumer is running
out of an product
• When another product seems
superior to the one currently used
The information search stage
An internal search involves the
scanning of one's memory to recall previous
experiences or knowledge concerning
solutions to the problem-- often sufficient for
frequently purchased products.
An external search may be necessary
when past experience or knowledge is
insufficient, the risk of making a wrong
purchase decision is high, and/or the cost of
gathering information is low.

Public sources (rating
services like Consumer
or sales people)

brands from which the buyer can
• go back to your past purchase– what were the
specific internal and external sources of
information that influenced your decision?

• what specific information influenced you?
• Initiator: the person who first suggests or thinks of the idea of buying a
particular product or service.
• Influencer: a person whose views or advice carry weight in making the
final buying decision
• Decider: the person who ultimately makes the final buying decision or
any part of it
• Buyer: the person who makes the actual purchase
• User: the person who consumes the product or service
Other people often influence a consumers purchase decision.
The marketer needs to know which people are involved in the
buying decision and what role each person plays, so that
marketing strategies can also be aimed at these people.
(Kotler et al, 1994).

Consumer decision making
varies with the level of involvement in
the purchasing decision
• Extensive: problem solving occurs when
buyers purchase more expensive, less
frequently purchased products in an
unfamiliar product category requiring
information search & evaluation; may
experience cognitive dissonance.
• Limited: problem solving occurs when buyers are
confronted with an unfamiliar brand in a familiar product
• Routine: response behavior occurs
when buyers purchase low cost, low risk, brand loyal,
frequently purchased, low personal identification or
relevance, items with which they are familiar.
• quickly list 10 items you have purchased in the past
• reexamine how long it took you to make a decision
• why did such a difference in decision occur?
• Previous experience: low level involvement
• Interest: high involvement
• Perceived risk of negative consequences: high involvement
• Situation: low to high due to risk
• Social visibility: involvement increases with product visibility
• Offer extensive information on high involvement products
• In-store promotion & placement is important for low involvement products
• Linking low-involvement product to high-involvement issue can increase sales

Compensatory Decision: Using product characteristics to guide decision
• Select the best overall brand-- evaluates brand options in terms of each
relevant attribute and computes a weighted or summated score for each brand. The
consumer chooses the brand with the highest score.
• Compensatory model because a positive score on one attribute can outweigh a
negative score on another attribute.
• Conjunctive Decision Rule (cutoff criteria)-- Consumer sets a minimum
standard for each attribute and if a brand fails to pass any standard, it is dropped from
• Reduces a large consideration set to a manageable size.
• Often used in conjunction with another decision rule.
• Disjunctive Decision Rule (rank by importance)-- sets a minimum
acceptable standard as the cutoff point for each attribute--any brand that exceeds the
cutoff point is accepted.
• Reduces large consideration set to a more manageable number of
• Consumer may settle for the first satisfactory brand as final choice or may
use another decision rule.
• Synthesized decision rule-- Consumers maintain overall evaluations of
brands in their long term memories. Brands on not evaluated on individual attributes
but on the highest perceived overall rating.
• think of an important purchasing decision
you have made
• what are some of the thoughts you have had
following your purchase? Any regrets?
• what has influenced those thoughts?
• how have you dealt with the discomfort?
• how has the company anticipated or dealt with
Can minimize through:
?Did I make a good decision?
Did I buy the right product?
Did I get a good value?

• psychological discomfort caused by inconsistencies
among a person’s beliefs, attitudes, and actions
• varies in intensity based on importance of issue and
degree of inconsistency
• induces a “drive state” to avoid or reduce dissonance
by changing beliefs, attitudes, or behaviors and
thereby restore consistency
Tendency to avoid information can be countered by eliciting interest,
norm of fairness, or perceive usefulness of information
Post-decision “buyer’s remorse” may be increased by importance or
difficulty or irreversibility of decision
Counter-attitudinal action, freely chosen with little incentive or
justification, leads to attitude change (e.g., new product at special low
• think of an innovation in your field
• describe different groups of employees in your
organization who would respond early and
favorably, as well as later and unfavorably
• what are the differences between these groups?
• how could you use this information to market the
innovation to them more effectively?
• Identify an innovation in your organization or an
organization you are familiar with
• Identify the subgroups who responded to the
innovation using the Rogers & Shoemaker
• What could have been done to facilitate
acceptance by each of these groups?
Nature of Active Cognitive Processing: (initial
attitude, argument quality, etc.)
Cognitive Structure Change: Are new cognitions
adopted and stored in memory? Are different
responses made salient than previously?
• personal relevance
• personal importance
• personal responsibility
Motivated to Process?
• dissonance arousal
• need for cognition
• cognitive complexity
• critical thinking
• distraction free
• low arousal
Ability to Process?
• appropriate schema
• message pace
• issue familiarity
• greater persistence
• resistant to counterattacks & fading
• predictive of behavior
• > brand memory
• > elaboration
• >usage intention
• > attitude accessibility
• > attitude confidence
• > attitude-behavior consistency
Peripheral Cues Present?
• reciprocity (obligated, did a favor)
• consistency (way it’s done, similar to before)
• social proof (peer pressure, conformity)
• liking (attractiveness, friendliness)
• celebrity (identification, prestige)
• authority (expertise, experience, credibility)
• rapid speech, forceful presentation, charismatic style
• scarcity (limited time offer)
• tangible rewards
• appealing visuals & music (emotional arousal)
• fear appeal
• weak counter-arguments
• susceptible to influence
