3. 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 media’s 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 people’s 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 instantlyconvert 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 Lasswell’s 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 1950’s, new paradigm in communication began to take shape & remain strong in 1960’s & 1970’s . 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 Lazarsfeld’s 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 people’s use of the media content. • 3. Lazarsfeld procedures and methodologies are conservative in assessing media’s 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. Survey’s 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 can’t 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 Lazarsfeld’s 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 Lazarsfeld’s 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:
