All About Theories for Communication.
Knowledge Gap Theory
This theory was first proposed in 1970 by Philip J Tichenor, then Associate Professor of Journalism and mass Communication, George A. Donohue, Professor of Sociology and Clarice. N Olien, Instructor in Sociology, all three researchers in the University of Minnesota. They defined the Knowledge Gap theory, as the infusion of mass media information into a social system increases higher socioeconomic status segments tend to acquire this information faster than lower socioeconomic status population segments so that gap in knowledge between the two tends to increase rather than decrease.” In simple words it means, as the access to mass media increases those particular segments of population inevitable gain information faster and hence the wide gap increases with the lower economic status of the population. The world is yet to see the complete effect of the new technologies but as the globe turns out more technological and the expense rises, it more goes out of the league of the poor. As a result the knowledge gap also widens and the people of the higher economic class gain the benefits more. If the Information services are not made equal for the entire society, this gap of information will increase over the years.
In this theory knowledge is treated as any other commodity which is not distributed equally throughout the society and the people at the top of the ladder has more easy access to it. This theory was used in the presidential election and it is was seen that when a new idea invades in the society, the people of the higher strata understand it better and hence the gap expands. But, events such as debates, free talks may help to reduce this gap.
Few reasons have been stated of why this pattern of gap exist
1. Communication Skills As a person receives more education, his communication skill increases and hence gathering information becomes easier for him. Along with this reading, understanding mad memory skills also become better and thus he understands the issues of various spheres better.
2. Stored information Via classrooms, textbooks, discussions, educated person is exposed to much more topics than a less educated person and hence his awareness is more.
3. Relevant Social Contact A person with more education has more social integration. This helps him to counter various perspectives, diverse stories etc which makes his understanding of public issues better.
4. Selective Exposure An educated person knows well of how to use optimum use of a medium while on the other hand a person with no knowledge is unlikely to know it. Hence he will be less aware of the issues around the world and less interested and may not also know of how it may affect him.
5. Media Target Markets For every product, news or any commodity a certain segment is targeted and it is usually the higher strata of the society who is targeted and hence the lower strata remains unaware.
Ways of Reducing the Gap
George A. Donohue and his other colleagues by the end of 1975 came up with three variables after a survey on local and national issues, which will help to reduce the gap and that failed this theory upto a certain extent.
- Impact of local issues It was seen that local issues that directly impacted the people had aroused more of social concern than national issues that did not have such a great impact and hence in these issues widened gap could be reduced.
- Level of social conflict surrounding the issue Until a communication breakdown, issues with more perceived conflict tends to grab more attention and weakening the knowledge gap hypothesis.
- Homogeneity of the community If it is a homogeneous community, the gap tends to be lesser than a wider heterogeneous community.
my name is Richard Paler, I am a Technology Communication student from Mindanao University Of Science and Technology (MUST) here in the Philippines. I have a question about the Knowledge Gap Theory. Can you explain or simplify assumption of your theory? And also what is the significance of the knowledge Gap theory?
I am looking forward for your reply. Thank you and God bless!
Hullo, i like your article, i am a student of communication in University of Jos, Nigeria. Can you relate the knowledge gap assumption with diffusion theory . Thanks
let me add more details :
Core Assumptions and Statements:
The knowledge gap can result in an increased gap between people of lower and higher socioeconomic status. The attempt to improve people’s life with information via the mass media might not always work the way this is planned. Mass media might have the effect of increasing the difference gap between members of social classes.
Tichenor, Donohue and Olien presented five reasons for justifying the knowledge gap:
1) People of high socioeconomic status have better communication skills, education, reading, comprehending and remembering information.
2) People of higher socioeconomic status can store information more easily or remember the topic form background knowledge.
3) People of higher socioeconomic status might have a more relevant social context.
4) People of higher socioeconomic status are better in selective exposure, acceptance and retention.
5) The nature of the mass media itself is that it is geared toward persons of higher socioeconomic status.
Media presenting information should realize that people of higher socioeconomic status get their information in a different way than lower educated people. Furthermore, this hypothesis of the knowledge gap might help in understanding the increased gap between people of higher socioeconomic status and people of lower socioeconomic status. It can be used in various circumstances.
The methods used in media researches concerned with knowledge gap are surveys of mass media and tests of knowledge.
i really apperciate you for this beneficial work, this theory was given to us as group assignment and through what i gained here it is of high recognition to me, Thanks and God bless
