Hoofdstuk 12 Treadwell (samenvatting flow) Content analysis - understanding communication content in numbers. Flashcards
Content analysis
is a quantitative, systematic, and objective technique for describing the
manifest content of communications.
Three types of content analysis
- Quantitative
- Systematic
- Manifest
What is quantitative content analysis?
we must count occurrences of whatever we are interested in
What is systematic content analysis?
we must count all relevant aspects of the sample, not arbitrarily pick what
aspects get analysed
What is manifest content analysis?
we count what is tangible and observable.
For example: we cannot count patriotism in consumer advertising because patriotism
is ultimately an abstract or latent (hidden) notion. What we count is the frequency
with which the word patriotism occurs, the frequency with which a national flag
appears, or perhaps the number of minutes music defined as patriotic is played.
Manifest content:
apparent or observable. The variables that operationalize the content.
Latent content:
hidden, not apparent, underlying meaning of the manifest content. Trying to
measure a concept.
Difference between the perspectives of latent content and manifest content:
The difference between trying to measure a concept (such as patriotism) and measuring the
variables that operationalize that concept (such as number of occurrences of the national
flag).
What is the onlything content analysis can represent?
it addresses only questions of content, e.g. ‘have representations of the
military on television changed since 9/11?’. However, ‘are media representations of the
military causing more people to enlist?’ is not a question content analysis can answer, though
it may tribute to an answer.
Limitations of content analysis
- It really only has application if used for comparisons. A content analysis indicating that
a politician used the term patriotism 17 times in the course of a campaign is not useful
information unless it has some point of reference, like ‘how does the frequency of the
term patriotism in politician X’s speeches compare with the that in politician Y’s?’ - Interpretation. Traditional perspectives on content analysis insist on counting manifest
or observable content. If you count the frequency with which the word patriotism
appears in a politician’s speeches overtime, and you detect an increase, you cannot
automatically imply the politician has become more patriotic over time. Only the term
has become more frequent.
What do you have to take in account regarding validity and reliability when it comes to content analysis?
Validity can be a problem with content analysis, looking at the examples above, but reliability
can be 100% with computer analysis of text.
A basic content analysis study typically has seven parts:
- Develop a hypothesis or research question about communication content
- Define the content to be analysed.
- Sample the universe of the content. Universe has the same meaning for media content
as population does for people. You sample media from a universe. (Universe is ‘faculty
vehicle’ in the example study from the book.) - Select units for coding. Units are the aspects or components of content sampled for
study. (Units are candidate names in the example of the book, because these are the
most obvious component of the campaign.) - Develop a coding scheme. Coding scheme is a systematic way or classifying or
categorizing all units of analysis. (Vehicles can be categorized by colour or
manufacturer for example.) - Assign each occurrence of a unit in the sample to a code in the coding scheme. E.g. the
first name Is recoded to number 1, the second to 2, etc. - Count occurrences of the coded units and report their frequencies.
After selecting a universe and developing a sample frame, one can question what units are
going to be sampled. There are, according to Krippendorff (1980) five possible types of units:
- Physical units
- Syntactical units
- Referential units
- Propositional units
- Thematic units
Physical units:
occupy an observable space in print media or time in audiovisual media.
For example: an entire comic strip or the individual panels within each strip.
Syntactical units:
units of language, like words or sentences. For example: the names
of political candidates in Rafael’s study of vehicle campaign stickers.
