Critical Discourse Analysis: Methods and Applications
What is Critical Discourse Analysis?
Critical Discourse Analysis (CDA) is a research approach dedicated to the analysis of language and communication from a critical viewpoint. It goes beyond merely describing linguistic features to investigate how language is actively used to shape and maintain power relations, ideologies, and social structures.
CDA systematically explores the often opaque relationships of causality and determination between discursive practices, events, texts, and wider social and cultural structures. It seeks to uncover how these practices arise from and are ideologically shaped by relations of power. CDA views a prevailing social order not as fixed or neutral, but as historically situated, socially constructed, and changeable.
Core Concepts in CDA
- Opacity: The discursive constructions or stories embedded within texts that are not always consciously apparent.
- Power: Viewed as an inevitable effect of discursive configurations that privilege certain positions over others.
- Subjectivity: Human identity is, at least in part, constructed or inscribed by discourse.
CDA is an interdisciplinary approach drawing on linguistics, sociology, anthropology, and critical theory. It involves analyzing linguistic features in real-life texts, situating them within their social, political, and historical context.
The Role of Language in Discourse
Language is the fundamental medium through which discourse is constructed. It is not merely a transparent vehicle for transmitting information but an active tool that performs the construction of reality.
Language as Social Practice
According to Norman Fairclough, language use is simultaneously constitutive of three key aspects of social life:
- Social identities: Constructing who we are.
- Social relations: Establishing and negotiating relationships.
- Systems of knowledge and belief: Contributing to shared understandings.
The relationship between language and its social context is dialectical; language is both shaped by society and actively shapes it.
Collocation Analysis in Discourse Research
Collocation analysis, used within Corpus-Assisted Discourse Studies (CADS), uncovers patterns in language use that are difficult to discern manually. Collocation refers to the phenomenon where certain words frequently appear near each other in a statistically significant way.
Methodology
Researchers use corpus linguistics software to identify collocates using statistical measures like logDice or log-likelihood. This process helps identify:
- Semantic preference: The tendency of a word to co-occur with semantically related terms.
- Discourse prosody: Evaluative meanings or associations that reveal ideological positions.
The Relevance of Frequency in Corpus Linguistics
Frequency analysis is the foundation of corpus-based research. By counting how often a word or phrase appears, researchers can identify salient linguistic features. However, frequency alone does not guarantee significance; context and distribution are equally vital.
Advanced techniques like keyness analysis compare word frequencies between a target corpus and a reference corpus to identify terms that are distinctively characteristic of a specific genre or discourse.
Concordance Lines and Discourse
A concordance list displays every occurrence of a search term within a corpus alongside its immediate context. Examining these lines is essential for:
- Identifying recurring patterns of language use.
- Revealing how social actors are represented.
- Fleshing out discourse prosody through close reading.
While interpreting large concordances can be challenging, strategies such as random sampling or sorting by adjacent words allow researchers to systematically reveal how language contributes to the construction and maintenance of discourses.
