3Introduction
- Effects of World War II saw the rise of the other
mass communication theories, in particular the
effects on the mass communication. - The outcome of the theories of propaganda gives
rise to the other moderate view of the power of
mass media. - The media were no longer feared as instruments of
political oppression and manipulation but instead
view a force wich has potential social good.
4- The medias power over the public was seen
limited (defying the Magic Bullet Theory). So
limited that no government regulations were
deemed necessary to prevent media manipulation. - The public was viewed as independent and
intelligent could resistant persuasion
extremist manipulation.
5- There was a belief that most people were
influenced by other factors rather than by the
media and that the role of opinion leaders were
responsible for guiding and stabilizing politics. - It was also believe that a very small minority of
people psychologically were vulnerable to direct
manipulation be the media.
6- Media were conceptualized (viewed) as relatively
powerless in shaping public opinion as compare to
other influences like individuals or group
memberships. - How and why did such radical transformation of
thinking in media theory takes place in a very
short period of time?
7- This change of thinking apparently was the result
of continuous research by Paul Lazarsfeld
(Prinston University later moved to Colombia
University) who developed the use of
sophisticated surveys to measure media influence
on how peoples thought and act. - These surveys provided convincing evidence that
media rarely are powerful and has direct
influence on individuals.
8- The effects were limited in scope. Media can
only influence few people in their thoughts and
actions which was referred to as limited effects
perspective. - That is the idea that the media have limited
effects on individuals
9- Only a small minority of the people had
psychological traits that made them vulnerable
to direct manipulation by media. - In fact, media were thought relatively powerless
in shaping public opinion. - How is that, such radical transformation of media
theory takes place in a short period of time?
10Paradigm Shift
- There is a shift in paradigm (believing,
thinking) and this led by Paul Lazarsfeld,
Hovland others, who did a lot of research on
media influence how people thought and acted. - The result shows that media rarely had any
direct influence on individuals. The media lack
the power to instantly convert an average people
11- The effect s were limited, effecting few people
or on trivial (less important) influence.
12- These findings were was later referred to as the
limited effects perspectives. - In times of war national crisis we turn to
media as a means of making sense of what is going
on trying to anticipate what might happen in
the future.
13- The more we depend on the media to do this, the
more we effectively placed our faith in the
media to guide us the more likely the media
will influence our lives. For this the Lasswells
propaganda theory works. - In times the power lies in ourselves in the
way we choose to allow media to effect our lives. - This is the essence of the limited effect
perspectives.
14Paradigm Shift
- There is a paradigm shift from war times to peace
time. i.e. There is a transformation of thinking
from one perspectives to the other. - During the war years, Lazarsfeld (Colombia U.)
Hovland (Yale U.) were drawn into media studies
to understand the power of propaganda the
threat it posed. They hope that if the media is
so powerful it might be controlled use for the
good.
15- But they found out that the media were not as
powerful as what was initially thought to be.
Media influence over public opinion were less
important than other factors such as social
status education. - During the 1950s, new paradigm in communication
began to take shape remain strong in 1960s
1970s . New methods of research were employed
namely survey interview (as part of the
empirical evidence)
16The Two-Step Flow of Information Influence
- Lazarsfeld believed that theories must be
supported by empirical data i.e. he used
inductive approach to theory construction, that
is research should began with empirical
observations not based on speculations. - He did two major studies on election campaigns
(1940) Erie, Ohio (known as Ohio study) in
(1943) in Decatur, Illinois.
17- The Ohio study he used 3000/43,000 residents
with 600 follow up interviewed. - In, Illinois he used 700 interviewed.
- Observations were done within 6 months period.
- His observations, that voters were divided into
three categories as follows
18- Early deciders, Waverers, Converts
Crystallizes. - 1. Early Deciders i.e those who choose the
candidate in May never change during the entire
campaign.
19- 2. The Waverers i.e. choose one candidate
later were undecided or switch to another. - 3. The Converts i.e. choose one candidate but
then voted the opponent. - 4. The Crystallizes i.e. those who had not choose
a candidate in May but made a choice in November.
20- He used a long detailed questionnaires on mass
media content (candidate speeches) - His argument is that if propaganda is so powerful
as mass society theory predicted this research
should allowed him to pinpoint media influence.
If the mass society theory was valid, he should
have found that most voters either Converts or
Waverers.
21- The results
- What he found was that
- 55 Early deciders. Choose one candidate in May
never change. - 28 Crystallizes made a predictable choice
stay with it. - 15 Waverers choose one candidate later switch
- 8 Converts choose one but later vote the
opponent.
22- He found little evidence that media played an
important role in influencing the crystallizes
the weavers or the converts. - Instead the voters are more likely to say they
are more likely influence from other people than
media. Often the decision was that they decide to
vote following the people closest to them. Not
because of media contents.
23- The influence of mass media was only to reinforce
a vote choice they had already made. - Media gives people more reasons for choosing a
candidate of their choice. - For crystallizes media helped party loyalties.
- Very little evidence to suggest media convert
voters. The converts were in fact those people
with divided loyalties.
24- They had group ties that pulled them to the
opposite direction. - Lazarsfeld found out that the early deciders were
the same people whose advice were being sought
after by other voters.
25- The early deciders were sophisticated who held
well-developed political views use the media
wisely critically. They are capable of
listening evaluating opposition speeches. They
gained information that help them advice others
so that others would be more resistant to
political campaign. - They are the gate-keepers. Screening information
passing on items that would help others share
their views.
26- These people were known as opinion leaders and
those who follow their advise were opinion
followers.
27- Lazarsfeld Katz (1955) based on their
experienced research conceptualized that how
people use the media to develop the of - Two-step flow theory
28- In this theory opinion leaders existed at all
level of society and that the flow of their
influence tended to be horizontal rather than
vertical. - Opinion leaders influenced people like themselves
rather than those above or below them in the
social order.
29- Opinion leaders differ from followers n term of
personal attributes, use the media more, were
socially active share social status.
30Limitations of Lazarsfelds Model
- 1. Survey cannot measure how people actually use
media on a day-to-day basis. E.g. the more
educated the person is the lesser they are
influence by the media. But the lesser the
educated person is, the more the stronger the
linked to various media.
31- 2. Surveys are expansive to study peoples use of
the media content. - 3. Lazarsfeld procedures and methodologies are
conservative in assessing medias power. It only
measuring voting decisions.
32- 4. Other research on Two-step flow produced
contradictory findings depending on (a) types of
information being transmitted and (b) social
conditions exist at that particular time. These
patterns are constantly changing.
33.
- 5. Survey can be useful for studying changes
over time but are considered crude techniques.
i.e. Lazarsfeld interview people once a month
problem of recalling. - 6. Surveys omit many other variables which could
further insights,
34- 7. The period is only true for the time
allocated. Result would definitely differ if
measurement taken at different timing.
35The Main points of Limited Effects Theory
- 1. Media rarely directly influence individuals.
- Most people are sheltered from direct
propaganda manipulation. People did not
believe everything what they hear or see in
the media. - They turn to others (family, friends,
coworkers social groups) for advice
interpretations. -
36- 2. There is a two-step flow of media influence.
- Media will be only be influential if the
opinion leaders who guide others are influenced
first. Because opinion leaders are
sophisticated , critical, not easily
manipulated by media content.
37- 3. By the time most people becomes adults, they
have developed strong held group commitments
such as political party, religious affiliations
that individual media messages are powerless
to overcome. -
38- These commitments cause people to reject certain
messages. E.g. Voters of certain parties will
only subscribe to the party magazines etc.
39- 4. When media effects do occur, it will be small
and isolated. - Small pocket will be influenced.
40What would be the Strength and weakness of the
Two-Step Flow Theory
- Strength
- 1. Focus on the environment in which effect can
and cant occur. - 2. Stress importance of opinion leaders in
formation of public opinion. - 3. This theory is based on inductive rather
than deductive reasoning.
41- 4. Effectively challenges the simplistic
notions of direct effects.
42- Weaknesses
- 1.It is limited to its time (time frame)
- 2. Report only the voting behavior.
- 3. Downplay reinforcement as an important media
effect. - 4. Uses survey method.
- 5. Later research demonstrate a multi flow
effects.
43Part II
44Two-Step Flow Theory
- SUMMARY (recapture)
- TWO-STEP FLOW THEORY
- The idea that messages pass from the media
through (inter-mediaries) such as opinion leaders
to opinion followers. - GATE-KEEPERS
- In two-step flow, people who screen media
messages pass on those messages that help
others share their views.
45- OPINION LEADERS
- In two-step flow, those who pass on information
to opinion followers. - OPINION FOLLOWERS
- In two-step flow, those who receive information
from opinion leaders.
46- MIDLE-RANGE THEORY
- A theory composed of empirical generalizations
based on empirical fact. - INDUCTIVE
- An approach to theory composed of empirical
generalizations based on empirical facts.
47Limitations in the Lazarsfelds Model
- 1. Survey cannot measure how people use media on
day-to day basis. - e.g. more educated people tend to
underestimate media influence on their
decisions whereas less educated people might
overestimate it. -
- 2. Surveys are very expansive way to study
specific media contents.
48- 3. The research design data analysis
procedures Lazarsfelds developed are very
conservative. - 4. Further research on two-step flow has
produced highly contradictory findings. - These flow has been found to differ greatly
according to the type of information being
transmitted the social conditions that exist.
49- 5. Surveys can be useful for studying changes
over time, but are relatively crude techniques. - 6. Surveys omit many other potentially
important variables.
50- INDIRECT EFFECTS THEORY
- When media seemed to have an effect, that effect
is filtered through other parts of the society
e.g. through friends or other social groups. - The following are the most important findings on
limited effect research between 1945-1960
51- 1. The media rarely directly influence They
turn to others (family, friends, coworkers,
social groups etc) for advice interpretations. - 2. There is two-step flow of media influence.
- Media will only be influential if he opinion
leaders who guide others are influence first.
52- 3. By the time most people become adults , they
have developed strong held values media are
powerless to overcome. - When media effects do occur they will be small
and isolated.
53Part III
54Attitude Change Theory
- Initiated in the 20th Century.
- Second World War provided the laboratory
development of the attitude change theory. - US went to war and needed to be able to mount an
effective counter offensive against the Nazi. - The war provided important motivation for
researchers interested in attitude change
research.
55Attitude Change Theory
- It was a simple convenience , were the military
saw soldiers in training, physiologists saw
subjects available.
56The Work of Hovland
- He was to undertake experimental evaluations of
the effectiveness of various military programs. - Testing on the military propaganda film Why we
fight and to measure its effectiveness
(indoctrination goals) using the experimental
design method. - The researcher hope that as the result of viewing
the films there might find shifts in peoples
attitudes.
57- Hovlands found that although the movies were
successful in increasing knowledge, they are not
as effective in influencing attitudes
motivations. - Film produced little change that what change
did occur was influence by peoples individual
differences. This contradict with mass society
theory.
58- The second finding was that as an outcome of the
theory they were able to direct the trends of
future attitude change theory. i.e. while films
were good in parting factual information but
certainly not effective in changing attitudes. - Thus using control experimental groups is good
method in changing peoples attitudes.
59- In particular the nature and the organizational
of the appeal. - They also found out that the more highly people
value their membership in a group, the more
closely their attitudes will conform to choose
the group.
60- They also found out that individuals status
(personality factors) has very little to do to be
persuaded. E.g. more intelligent people are more
likely to be persuaded if the message they
receive is based on solid and logical arguments.
61- The reasons that why mass media is rarely direct
because it is always mediated By - (a) Individual differences
- (b) Group membership or relationships.
- The two factors serve as effective barriers to
media influence.
62Persuasion research influencing media
- In persuasion and attitude change theory two
factors are important - 1. Reorganization of the individual
differences. (psychological make up) (DeFleur
1970). - 2. Social categories
- That is the broad assumptions that urban
societies are collectively and whose behavior
can be aggregated (or more or less uniform).
63- People with similar backgrounds (age, gender,
income level, religious affiliations etc) will
have similar patterns of media exposure and
similar reactions to that exposure. - This generalizations derived partly from
Lazarfelds work.
64Selective Processes
- The change theory was adopted by influential
scholars like Lazarfeld, to Klaper to De Fleur
and was later developed into the idea of
cognitive consistency.
65(No Transcript)
66Cognitive Dissonance Theory
- COGNITIVE CONSISTENCY
- The idea that people consciously and
unconsciously work to preserve their existing
views and avoiding messages that challenged them. - Leon Festinger took up this idea and developed in
his theory of Cognitive Dissonance.
67- COGNITIVE DISSONANCE
- The idea that information that is inconsistent
with a persons already held attitude created
psychological discomfort or dissonance. - People generally work to keep their knowledge of
themselves and their knowledge of the world
somewhat consistence.
68- If for some reasons a person knows several things
that are not psychologically consistent with
another, he will, in variety of ways, try to make
them more consistence. - This process is known as selective process.
69- SELECTIVE PROCESS
- Exposure (attention), retention, and perception,
physiological process design to reduce
dissonance. - This defense mechanisms that we use to protect
ourselves (our egos) from information that would
threaten us.
70- Klapper (1960) wrote by and large people tend to
expose themselves to those mass communications
that are in accord with their existing attitudes
and interest. Consciously or unconsciously they
avoid communications of the opposite. In the
event that they are exposed to unsympathetic
materials, they often seem not to perceive it, OR
interpret to fit their existing views OR to
forget about it.
71Persuasion influenced on the study of media.
- Attitude Change Researchers identify three forms
of Selectivity - 1. Selective Exposure
- 2. Selective Retention
- 3. Selective Perception
72Selective exposure
- People tendency to expose themselves to messages
that are consistent with their preexisting
attitudes and belief. - E.g. In Lazarsfelds study of the voters, 2/3 of
the voters managed to see and hear more of their
own sides propaganda than the opposites.
73Selective Retention
- People end to remember best and longest those
messages that are meaningful to them.
74Selective Perception
- People will alter the meaning the messages so
they become consistent wit preexisting attitudes
and beliefs. - It is a mental or psychological image of the
message so that the meaning is in line the
persons belief and attitudes.
75- E.g. Allport Poseman (1945) study of the rumors
proved this point (the fight between a white
black American. Originally the knife was in the
hand of the white man, and because of rumors
spreads, it quickly changes to the black man). - 60 yrs. had passed by can the same scenario
happened in 2005? What do you think?
76Applications of Attitude Change Theory
- STRENGTHS
- 1. It pays a deep attention to the process in
which messages can cant have effects. - 2. Provides insight into influence of
individual differences group affiliation in
shaping media influence. - 3. Attention to selective processes helps
clarify how individuals processes information
77- WEAKNESSES
- 1. Manipulation of the variables (e.g.
messages) overestimate the power and
underestimate the medias influence. - 2. Focuses only on effects of media messages
- 3. Uses attitude change as only measure of
effects ignoring other subtle forms of medias
influence.
78Limitations of Persuasion Research
- 1. The experiments conducted in laboratory the
results cannot be generalized because the time
conducted too short. - 2. Experiments suited only to measure
immediate effects of specific media content on
small homogeneous groups of people. - 3. Limitation of standardized instruments
(statistics).
79- 4. Experiments are crude techniques for
examining the influence of media over time. - 5. Limitation of experimentation design
80At the end of this lesson you should have
acquired the following concepts
- 1. Attitude Change Theory
- 2. Festingers Cognitive Dissonance.
- 3. Selective processes Selective Exposure,
Selective Retention Selective Perception. - 4. Strength weaknesses of the Attitude Change
Theory.
