What is Communication? 
 The word communication has been oriented from a Latin word 
“Communes” which means something common. Therefore, 
when we communicate. We are indeed trying to establish 
commonness of thoughts or feelings with other individuals 
 Communication is a process in which the message moves from 
source to destination 
 Purpose of Communication 
a) Change in the behavior of receiver (cognitive thinking, feeling, acting) 
b) To inform, educate and entertainment
Elements of Communication 
 Source 
 Encoding (the process of giving physical shape to one’s idea) 
 Message (coded idea of the sender. Written script etc.) 
 Channel (medium) 
 Decoding (retranslation of the message) 
 Receiver 
 Feed back 
 Noise
Types of Communication 
 Intrapersonal communication 
(takes place with himself) 
 Interpersonal Communication 
(between two or a small group of 
persons) 
 Macro Group Communication 
(speech of a political leader with 
instant feedback) 
 Mass communication
Hurdles of Communication 
Physical Psychological 
 Physical problem in transmitting 
a message from its source to 
destination 
a) Signal problem in TV watching 
b) Knocking doors during lecture 
c) Noise during Telephone calls 
 How to overcome channel 
noise? 
By repetition of the main idea 
 Semantic Noise 
 Field of Experience 
 Cognitive dissonance 
 Frame of Reference 
 Poor understanding
Models of Mass Communication Research 
 Definition and Function 
 Model is considered as a consciously simplified description in graphic form of a 
piece of reality 
 A model seeks to show the main elements of any structure and the relationship 
between these elements 
 Deutsch (1966) notes the following main advantages of models in social 
sciences 
1. They have an organizing function of ordering and relating system to each other by 
providing us with images of wholes that we might not otherwise perceive 
2. They help in explaining the key points of a process of system 
3. Claim only to describe the structure of a phenomenon 
4. Theoretical and simplified representation of the real world 
5. A model is not an explanatory device by itself, but it helps to formulate theory 
 Aristotle (384 BC – 322 BC) said, The study of communication can be 
organized in three categories
Types 
 There are three main types of communication models 
1. Linear Model 
The linear model views communication as a one-way or linear process in which the speaker 
speaks and the listener listens 
a) Lasswell Model (1948) 
b) Shannon and Weaver’s Model (1949) 
c) Braddock’s Model (1958) 
2. Interactive Model 
 Wood (2009) Introduced more interactive model that saw the receiver or listener providing 
feedback to the sender or speaker. 
 This model also indicates that the speaker and listener communicate better if they have 
common fields of experience 
 This model fails to show that communication is a dynamic process which changes over 
time.
Cont… 
 Transition Model 
The transactional model shows that the elements in communication are interdependent. 
Each person in the communication act is both a speaker and a listener, and can be 
simultaneously sending and receiving messages 
There are three implications in the transactional model 
1. Communication is an ongoing and continuously changing process. You are 
changing, the people with whom you are communicating are changing and your 
environment is also continually changing as well 
2. In any transactional process, each element exists in relation to all the other 
elements. 
3. Each person in the communication process 
reacts depending on factors such as their background, 
prior experiences, attitudes, cultural beliefs and 
self-esteem
The Lasswell Formula 
 The American political scientist Harold D. Lasswell began an article in 1948 with 
perhaps the most famous single phrase in communication research. 
 A convenient way to describe an act of communication is to answer the following 
questions: 
 Barddock (1958) found that there are more considerations to work with than those 
five presented by Lasswell. 
1. The circumstances under which a message is sent 
2. For what purpose the communicator says something 
 Criticism 
 Lasswell’s Model has been criticized, not having the element of feedback
Shannon and Weaver Model of Communication 
 Worked for Bell Telephone Laboratory and his theories and models primarily 
applied to its particular field of communication involving questions such as: 
 Which kind of communication channel can bring through the maximum amount of 
signals? 
 How much of transmitted signals will be destroyed by noise underway from 
transmitter to receiver? 
According to this model, communication is described as a linear, one 
way process. ‘The model states five functions to be performed and notes one dis-functional 
factor, noise.
De Fluer Model of Communication(1966) 
 In Shannon and weaver’s model messages are transformed through 
transmitter by decoding 
 De fluer adds another set of components to the original Shannon and 
Weaver model to show, how the source gets its feedback which gives the 
source a possibility of adapting more effectively its way of communicating 
to destination. 
 Shanon and Weaver’s model having linearity but this model having the 
element of mass communication 
 The source get limited feedback from the audience in this model
The Osgood and Schramm Circular Model 
 Shannon’s model could be described as linear, we may say that the Osgood- 
Schramm model is highly circular 
 Shannon’s interest is primarily directed to the channels mediating between 
the sender and receiver but Schramm and Osgood devote their discussion to 
the behaviour of main actors in communication process 
 Shannon’s model having the element of linear communication but this 
model is very useful in describing interpersonal communication 
 Criticism 
 The model conveys a feeling of equality in communication
Newcomb’s Symmetry Model 
 Newcomb (1953) approach to communication is that of a social 
psychologist concerned with interaction between human beings. 
 His model is reminiscent of the diagrams of group networks made by social 
psychologists and is one of the early formulations of cognitive consistency 
 In its simplest form of the communication acts, a person, A, transmits 
information to another person, B, about something X 
 The model assumes that A’s attitude toward B and toward X are independent
Scientific Method 
 Science serves as a guard against untested assumption 
 The scientific method differs from other methods of obtaining knowledge in 
that it is based on observation and the testing of our assumptions 
 Methods of establishing truth were not commonly employed before the 
development of the scientific method include tenacity, authority and 
intuition (Cohen & Nagel, 1934) 
a) Method of Tenacity: true because it is always true (ex. I don’t believe 
advertising because my parents said so). 
b) Method of Intuition: true because it is self-evidence (ex. A Creative 
Director uses certain method and always work). 
c) Method of Authority: true because an authoritarian person said so. 
d) Method of Science: “an organized, objective, controlled, qualitative or 
quantitative empirical analysis of one or more variables”
Imagination in Science 
 A great 19th century scientist Huxley once defined science as “trained and 
organised common sense” and added that theory building is something you 
engage in “every day and every hour of your lives” 
 The father of the relativity theory, Albert Einstein, said, “The whole of 
science is nothing more than a refinement of every day thinking” 
 Scientific generalization about Reality 
• Scientists seek to make generalizations about the nature of reality 
• Reliability 
• Validity 
• Replicable until the confirmation of hypothetical approving 
 Safeguards against Bias and Fraud 
Findings can be replicated till reliability has been approved
What is Research? 
 Research is the systematic process of collecting and analysing information 
to increase our understanding the phenomenon under study 
 It is the process in which scientific and systematic methods are involved on 
social phenomena to develop and invent new ideas 
 Ker linger (1986) defines scientific research as a systematic, controlled, 
critical and hypothetical proportions
Research phases in Media 
 Phase 1: The Medium itself 
 There is an interest in the medium 
itself. 
 What is it? 
 How does it works? 
 What technology does it involve? 
 What functions and services does it 
provide? 
 Phase 2: Uses and users of the 
medium 
 How do the people use this medium in 
real life? 
 Do they use it for information only, to 
save time, for entertainment or for 
other reasons? 
 Do children use it? 
 Do adults use it and why? 
 Phase 3: Effects of the medium 
 Does it change peoples perspective 
about anything? 
 Are there any harmful effects 
related to using the medium? 
 Phase 4: How the medium can 
be improved? 
 How can the new technology be 
used to perfect or enhance the 
sight and sound of the medium?
Objectives of Research 
 To find out some thing 
 To investigate something 
 To test something 
 To verify something 
 To draw a conclusion about some 
phenomenon 
 To develop better understanding of 
a particular phenomenon 
 To find solution of a particular 
problem 
 To check the hypothesis
Sectors of Research 
Academic Research Private Research 
 Scholars from colleges and 
universities conduct academic 
sector research. This type of 
research has theoretical approach 
and the result of this type of 
research help to explain the mass 
media and their effects on 
individuals 
 Exp: 
The effects of media in promoting 
violence etc. 
 Nongovernmental or private 
organizations or their research 
consultants conduct private sector 
research and the result of this type 
of research facilitate their decision 
making policy 
 Exp: 
PR campaigns
Process/Steps of Research 
 The scientific evaluation of any problem follow a sequence of steps to 
increase the chance that it will produce relevant data 
 Research process consists of series of steps necessary to carryout research 
 Steps in the process of research 
i. Selection of the topic 
ii. Literature review 
iii. Statement of hypothesis or research question 
iv. Determine of appropriate methodology and research design 
v. Data collection 
vi. Analyse and interpretation of data 
vii. Presentation of results 
viii. Replication
Types of Scientific Research Methods 
Quantitative Research 
Methods 
 Survey Research 
 Content analysis 
 Experimental Research 
 Qualitative Research 
Methods 
 Focus Group 
 In-depth Interviews
Cont… 
Qualitative Research Quantitative Research 
 Primarily inductive process 
 More subjective 
 Data is in the form of words 
 More in-depth information in few 
cases 
 No statistical tests 
 Specific to general 
 Researcher is the data gathering 
instrument 
 Primarily deductive process 
 More objective 
 Number-based 
 Less in-depth 
 Statistical tests are used for 
analysis 
 General to specific 
 Researcher uses tools, such as 
questionnaires, coding sheets
Survey Research 
 Hansen (1998), Survey Research seeks to provide empirical data, collected 
from a population of respondents on a whole number of topics or issues 
 Bertrand & Hughes (1999) explain survey research as a research method 
involving the use of questionnaires to gather data about people and their 
thoughts and behaviours 
 Types of Survey 
1. Descriptive Survey 
A descriptive survey attempts to describe or document current conditions 
or attitudes that is, to explain what exists at the moment. 
Exp: Survey during a meeting or in a live talk show 
1. Analytical Survey 
An analytical survey attempts to describe and explain why situation exists. 
In this approach, two or more variables are usually examined to investigate 
research questions or test hypothesis
Cont… 
Process of Survey 
 Research Question 
 Define population 
 Select sample 
 Questionnaire 
 Pre-test 
 Data collection 
 Data analysis 
 Research Report
Content Analysis 
 Content analysis is a research technique for the objective, systematic and 
quantitative description of the manifest content of communication (Wimmer & 
Dominick) 
Process of Content Analysis Research 
1. Formulate Research Question or Hypothesis 
2. Define the universe in question 
3. Select an appropriate sample from the population 
4. Select a unit of analysis 
5. Construct the categories of the content to be analysed 
6. Establish a quantification system 
7. Train coders and conduct pilot study 
8. Code the content according to the established definitions 
9. Analyse the collected data 
10. Draw conclusion
Experimental Research Technique 
 Oldest method in mass media with less usage 
 Examining the basic techniques with the discussion of the controlled 
laboratory experiments and field experiments 
 Laboratory studies involved both manipulation and observation. In the 
simplest form of an experiment, researchers manipulate independent 
variables and then observe the responses of subjects on the dependent 
variables
Focus Group 
 The focus group/group interviewing is a research strategy for understanding 
audience attitudes and behaviour 
 From 6 to 12 people are interviewed simutaneusly, with a moderator 
 The identifying charactaristics of the focus group is contrlled group 
discussion (Wimmer & Dominik, 2000)
Case Studies 
 The case studies method is a qualitative research technique. 
 A case study uses as many data sources as possible to systematically 
investigate individuals, groups, organizations or events 
 Case studies are conducted when a researcher need to understand or explain 
a phenomenon (Wimmer & Dominick, Communication Research, P.P 86, 9th 
edition)
Conclusion 
 Implication of predictions that can be verified by tests 
 Evaluation of information theory according to the criteria allowing to 
organize, order and relate data to show similarities that had previously not 
perceived 
 As a scientist, in any field of investigation develops and tests hypotheses 
about the nature f the world in a particular area of interest, the process of 
observation, testing and replication 
 Building of a theory that provides explanations and make possible 
predictions approving hypothesis 
 Answer to specific questions

Scientific Method and Models of Mass Communication Research: By Abid Zafar Ms. Mass Communication & Media Studies

  • 1.
  • 2. Scientific Method and Models of Mass Communication Research: By Abid Zafar Fall 2014 Communication Theory International Islamic University Islamabad
  • 3. What is Communication?  The word communication has been oriented from a Latin word “Communes” which means something common. Therefore, when we communicate. We are indeed trying to establish commonness of thoughts or feelings with other individuals  Communication is a process in which the message moves from source to destination  Purpose of Communication a) Change in the behavior of receiver (cognitive thinking, feeling, acting) b) To inform, educate and entertainment
  • 4. Elements of Communication  Source  Encoding (the process of giving physical shape to one’s idea)  Message (coded idea of the sender. Written script etc.)  Channel (medium)  Decoding (retranslation of the message)  Receiver  Feed back  Noise
  • 5. Types of Communication  Intrapersonal communication (takes place with himself)  Interpersonal Communication (between two or a small group of persons)  Macro Group Communication (speech of a political leader with instant feedback)  Mass communication
  • 6. Hurdles of Communication Physical Psychological  Physical problem in transmitting a message from its source to destination a) Signal problem in TV watching b) Knocking doors during lecture c) Noise during Telephone calls  How to overcome channel noise? By repetition of the main idea  Semantic Noise  Field of Experience  Cognitive dissonance  Frame of Reference  Poor understanding
  • 7. Models of Mass Communication Research  Definition and Function  Model is considered as a consciously simplified description in graphic form of a piece of reality  A model seeks to show the main elements of any structure and the relationship between these elements  Deutsch (1966) notes the following main advantages of models in social sciences 1. They have an organizing function of ordering and relating system to each other by providing us with images of wholes that we might not otherwise perceive 2. They help in explaining the key points of a process of system 3. Claim only to describe the structure of a phenomenon 4. Theoretical and simplified representation of the real world 5. A model is not an explanatory device by itself, but it helps to formulate theory  Aristotle (384 BC – 322 BC) said, The study of communication can be organized in three categories
  • 8. Types  There are three main types of communication models 1. Linear Model The linear model views communication as a one-way or linear process in which the speaker speaks and the listener listens a) Lasswell Model (1948) b) Shannon and Weaver’s Model (1949) c) Braddock’s Model (1958) 2. Interactive Model  Wood (2009) Introduced more interactive model that saw the receiver or listener providing feedback to the sender or speaker.  This model also indicates that the speaker and listener communicate better if they have common fields of experience  This model fails to show that communication is a dynamic process which changes over time.
  • 9. Cont…  Transition Model The transactional model shows that the elements in communication are interdependent. Each person in the communication act is both a speaker and a listener, and can be simultaneously sending and receiving messages There are three implications in the transactional model 1. Communication is an ongoing and continuously changing process. You are changing, the people with whom you are communicating are changing and your environment is also continually changing as well 2. In any transactional process, each element exists in relation to all the other elements. 3. Each person in the communication process reacts depending on factors such as their background, prior experiences, attitudes, cultural beliefs and self-esteem
  • 10. The Lasswell Formula  The American political scientist Harold D. Lasswell began an article in 1948 with perhaps the most famous single phrase in communication research.  A convenient way to describe an act of communication is to answer the following questions:  Barddock (1958) found that there are more considerations to work with than those five presented by Lasswell. 1. The circumstances under which a message is sent 2. For what purpose the communicator says something  Criticism  Lasswell’s Model has been criticized, not having the element of feedback
  • 11. Shannon and Weaver Model of Communication  Worked for Bell Telephone Laboratory and his theories and models primarily applied to its particular field of communication involving questions such as:  Which kind of communication channel can bring through the maximum amount of signals?  How much of transmitted signals will be destroyed by noise underway from transmitter to receiver? According to this model, communication is described as a linear, one way process. ‘The model states five functions to be performed and notes one dis-functional factor, noise.
  • 12. De Fluer Model of Communication(1966)  In Shannon and weaver’s model messages are transformed through transmitter by decoding  De fluer adds another set of components to the original Shannon and Weaver model to show, how the source gets its feedback which gives the source a possibility of adapting more effectively its way of communicating to destination.  Shanon and Weaver’s model having linearity but this model having the element of mass communication  The source get limited feedback from the audience in this model
  • 13. The Osgood and Schramm Circular Model  Shannon’s model could be described as linear, we may say that the Osgood- Schramm model is highly circular  Shannon’s interest is primarily directed to the channels mediating between the sender and receiver but Schramm and Osgood devote their discussion to the behaviour of main actors in communication process  Shannon’s model having the element of linear communication but this model is very useful in describing interpersonal communication  Criticism  The model conveys a feeling of equality in communication
  • 14. Newcomb’s Symmetry Model  Newcomb (1953) approach to communication is that of a social psychologist concerned with interaction between human beings.  His model is reminiscent of the diagrams of group networks made by social psychologists and is one of the early formulations of cognitive consistency  In its simplest form of the communication acts, a person, A, transmits information to another person, B, about something X  The model assumes that A’s attitude toward B and toward X are independent
  • 15. Scientific Method  Science serves as a guard against untested assumption  The scientific method differs from other methods of obtaining knowledge in that it is based on observation and the testing of our assumptions  Methods of establishing truth were not commonly employed before the development of the scientific method include tenacity, authority and intuition (Cohen & Nagel, 1934) a) Method of Tenacity: true because it is always true (ex. I don’t believe advertising because my parents said so). b) Method of Intuition: true because it is self-evidence (ex. A Creative Director uses certain method and always work). c) Method of Authority: true because an authoritarian person said so. d) Method of Science: “an organized, objective, controlled, qualitative or quantitative empirical analysis of one or more variables”
  • 16. Imagination in Science  A great 19th century scientist Huxley once defined science as “trained and organised common sense” and added that theory building is something you engage in “every day and every hour of your lives”  The father of the relativity theory, Albert Einstein, said, “The whole of science is nothing more than a refinement of every day thinking”  Scientific generalization about Reality • Scientists seek to make generalizations about the nature of reality • Reliability • Validity • Replicable until the confirmation of hypothetical approving  Safeguards against Bias and Fraud Findings can be replicated till reliability has been approved
  • 17. What is Research?  Research is the systematic process of collecting and analysing information to increase our understanding the phenomenon under study  It is the process in which scientific and systematic methods are involved on social phenomena to develop and invent new ideas  Ker linger (1986) defines scientific research as a systematic, controlled, critical and hypothetical proportions
  • 18. Research phases in Media  Phase 1: The Medium itself  There is an interest in the medium itself.  What is it?  How does it works?  What technology does it involve?  What functions and services does it provide?  Phase 2: Uses and users of the medium  How do the people use this medium in real life?  Do they use it for information only, to save time, for entertainment or for other reasons?  Do children use it?  Do adults use it and why?  Phase 3: Effects of the medium  Does it change peoples perspective about anything?  Are there any harmful effects related to using the medium?  Phase 4: How the medium can be improved?  How can the new technology be used to perfect or enhance the sight and sound of the medium?
  • 19. Objectives of Research  To find out some thing  To investigate something  To test something  To verify something  To draw a conclusion about some phenomenon  To develop better understanding of a particular phenomenon  To find solution of a particular problem  To check the hypothesis
  • 20. Sectors of Research Academic Research Private Research  Scholars from colleges and universities conduct academic sector research. This type of research has theoretical approach and the result of this type of research help to explain the mass media and their effects on individuals  Exp: The effects of media in promoting violence etc.  Nongovernmental or private organizations or their research consultants conduct private sector research and the result of this type of research facilitate their decision making policy  Exp: PR campaigns
  • 21. Process/Steps of Research  The scientific evaluation of any problem follow a sequence of steps to increase the chance that it will produce relevant data  Research process consists of series of steps necessary to carryout research  Steps in the process of research i. Selection of the topic ii. Literature review iii. Statement of hypothesis or research question iv. Determine of appropriate methodology and research design v. Data collection vi. Analyse and interpretation of data vii. Presentation of results viii. Replication
  • 22. Types of Scientific Research Methods Quantitative Research Methods  Survey Research  Content analysis  Experimental Research  Qualitative Research Methods  Focus Group  In-depth Interviews
  • 23. Cont… Qualitative Research Quantitative Research  Primarily inductive process  More subjective  Data is in the form of words  More in-depth information in few cases  No statistical tests  Specific to general  Researcher is the data gathering instrument  Primarily deductive process  More objective  Number-based  Less in-depth  Statistical tests are used for analysis  General to specific  Researcher uses tools, such as questionnaires, coding sheets
  • 24. Survey Research  Hansen (1998), Survey Research seeks to provide empirical data, collected from a population of respondents on a whole number of topics or issues  Bertrand & Hughes (1999) explain survey research as a research method involving the use of questionnaires to gather data about people and their thoughts and behaviours  Types of Survey 1. Descriptive Survey A descriptive survey attempts to describe or document current conditions or attitudes that is, to explain what exists at the moment. Exp: Survey during a meeting or in a live talk show 1. Analytical Survey An analytical survey attempts to describe and explain why situation exists. In this approach, two or more variables are usually examined to investigate research questions or test hypothesis
  • 25. Cont… Process of Survey  Research Question  Define population  Select sample  Questionnaire  Pre-test  Data collection  Data analysis  Research Report
  • 26. Content Analysis  Content analysis is a research technique for the objective, systematic and quantitative description of the manifest content of communication (Wimmer & Dominick) Process of Content Analysis Research 1. Formulate Research Question or Hypothesis 2. Define the universe in question 3. Select an appropriate sample from the population 4. Select a unit of analysis 5. Construct the categories of the content to be analysed 6. Establish a quantification system 7. Train coders and conduct pilot study 8. Code the content according to the established definitions 9. Analyse the collected data 10. Draw conclusion
  • 27. Experimental Research Technique  Oldest method in mass media with less usage  Examining the basic techniques with the discussion of the controlled laboratory experiments and field experiments  Laboratory studies involved both manipulation and observation. In the simplest form of an experiment, researchers manipulate independent variables and then observe the responses of subjects on the dependent variables
  • 28. Focus Group  The focus group/group interviewing is a research strategy for understanding audience attitudes and behaviour  From 6 to 12 people are interviewed simutaneusly, with a moderator  The identifying charactaristics of the focus group is contrlled group discussion (Wimmer & Dominik, 2000)
  • 29. Case Studies  The case studies method is a qualitative research technique.  A case study uses as many data sources as possible to systematically investigate individuals, groups, organizations or events  Case studies are conducted when a researcher need to understand or explain a phenomenon (Wimmer & Dominick, Communication Research, P.P 86, 9th edition)
  • 30. Conclusion  Implication of predictions that can be verified by tests  Evaluation of information theory according to the criteria allowing to organize, order and relate data to show similarities that had previously not perceived  As a scientist, in any field of investigation develops and tests hypotheses about the nature f the world in a particular area of interest, the process of observation, testing and replication  Building of a theory that provides explanations and make possible predictions approving hypothesis  Answer to specific questions
