Introduction
  • 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?

10
Paradigm 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.

14
Paradigm 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)

16
The 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.

30
Limitations 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.

35
The 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.

40
What 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.

43
Part II
44
Two-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.

47
Limitations 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.

53
Part III
54
Attitude 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.

55
Attitude Change Theory
  • It was a simple convenience , were the military
    saw soldiers in training, physiologists saw
    subjects available.

56
The 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.

62
Persuasion 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.

64
Selective 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.

66
Cognitive 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.

71
Persuasion influenced on the study of media.
  • Attitude Change Researchers identify three forms
    of Selectivity
  • 1. Selective Exposure
  • 2. Selective Retention
  • 3. Selective Perception

72
Selective 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.

73
Selective Retention
  • People end to remember best and longest those
    messages that are meaningful to them.

74
Selective 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?

76
Applications 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.

78
Limitations 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

80
At 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.
