Sesame Street<br />Mass Media‘s Role<br />Profile: educational TV programming<br />Target group: disadvantaged inner city kids<br />Goal: bring all kids up to a basic level to prepare them for school<br />Method: combining information and entertainment<br />Researcher: Thomas Cook – 1975<br />Findings: the gap still existed between kids with a higher level of education compared to kids with less<br />Exception: heavy viewers were able to narrow the gap<br />

  13. 13. In the Beginning...<br />Knowledge Gap Theory<br />Information and knowledge usually spread <br />unequally to all groups within social systems<br />
  14. 14. Reasons<br />Knowledge Gap Theory<br />Predicted Knowledge Gap<br />
  15. 15. Hypothesis<br />Knowledge Gap Theory<br /> As the infusion of mass media information into a social system increases, segments of the population with higher socioeconomic status tend to acquire this information at a faster rate than the lower status segments so that the gap in knowledgebetween these segments tends to increase rather than decrease<br />
  16. 16. Study Variables<br />Knowledge Gap Theory<br />IV<br />DV<br />variation in mass media publicity or media use<br />knowledge gap according to social economic status<br />Knowledge gap becomes the degree of relationship between education and knowledge<br />
  17. 17. Operational Hypothesis<br />Over time, acquisition of knowledge of a heavily publicized topic will proceed at a faster rate among better educated person than among those with less education<br />2. At a given point in time, there should be a higher correlation between acquisition of knowledge and education for topics highly publicized in the media than for topics less highly publicized.<br />Knowledge Gap Theory<br />A<br />B<br />C<br />
  18. 18. Assumptions<br />Education indicates socio-economic status<br />Information flow may be characterized by irreversible linear or curvelinear trends<br />No upper limit of information has been reached<br />PA and science news have less appeal and value to <br />Knowledge Gap Theory<br />
  19. 19. Methods - Tichenor<br />Types of research:<br />Time trends<br />Newspaper strike<br />Field experiment<br />Methods: <br /> - surveys of mass media<br /> - tests of knowledge<br />Knowledge Gap Theory<br />
  20. 20. 4 different polls: <br />Question: Do you believe men would reach the moon in the future?<br />Results:<br /> - Gap between college educated and those with lower education<br />- Significant increase of knowledge over years<br />1. Time trend<br />Knowledge Gap Theory<br />
  21. 21. 2. Newspaper Strike Study<br />Knowledge Gap<br />Studied the effects of withdrawing mass media influence<br />Findings:<br />Less of a knowledge difference between better and less educated people in the strike community<br />
  22. 22. 3. Minneapolis – St. Paul Experiment<br />Knowledge Gap Theory<br />Reader understanding: <br />22 medical and biological research articles<br />21 social science articles<br />Sample: 600 persons – metropolitan area<br />Objective: readership and reiteration of information<br />
  23. 23. Findings<br />Most of the data seems to be consistent with the increasing knowledge gap hypothesis<br />A difference in knowledge according to educational level<br />Regardless of educational background, knowledge increases over years<br />When deprived of information, the gap between more and less educated persons lessens<br />People may develop trained capacities to react to various stimuli<br />Knowledge Gap Theory<br />
  24. 24. Relevance<br /> The Knowledge Gap hypothesis seems to be a fundamental explanation for the apparent failure of mass publicity to inform the public at large<br />The people reached by campaigns tend to be the better educated, the younger and the men, while less educated and older people ignore the campaign<br />Knowledge Gap Theory<br />
  25. 25. Criticism<br />The psychological level of analysis should also be analyzed: motivation, relevance, cognitive schemata, threat and interest.<br />Gender and race were not taken into consideration<br />PA and news science are less valuable and appealing to the general public<br />Income, occupation may also be relevant differentiators<br />Knowledge Gap Theory<br />
  26. 26. Refinement of the Theory<br />
  27. 27. Closing the Gap<br />Tichenor<br />Shift from an abstract notion of social systems to a concrete geographically grounded idea of community<br />Kw gap decreases for local issues under conditions of high significance, high community conflict and homogenity of population<br />Refinement of the <br />Theory<br />?<br />
  28. 28. Individual Voluntarism<br />Ettema & Kline<br />Shift from societal naturalism to individual voluntarism<br />The individual is seen as an entity constructing meanings unique to their circumstances<br />Refinement of the <br />Theory<br />
  29. 29. Influence Gap?<br />Brantgarde<br />Expanded the knowledge gap to include more than knowledge, namely social relations (opinion leaders)<br />Knowledge gap becomes the influence gap<br />Refinement of the <br />Theory<br />
  30. 30. Further Questions<br /> Q: If media widens these knowledge gaps, under which circumstances can they be closed?<br /> Knowledge gaps are not intractable. <br />Contributory conditions that could reduce knowledge gaps: <br />content domains<br />channel influence <br />social conflict and community mobilization<br />the structure of communities<br />individual motivational factors.<br />
