Perception and ideology are two distinct concepts within the appraisal framework of Systemic Functional Linguistics (SFL). Perception refers to the way individuals interpret and understand the world around them, often influenced by their experiences, cultural background, and social context. It is a cognitive process that involves the interpretation of sensory information to form a mental representation of reality. Perception can be influenced by various factors, including language, which is why SFL views linguistic representation as a representation of utterances that uses to represent linguistic information about the phonetics, phonology, morphology, syntax, or semantics[1].
On the other hand, ideology is a social construct that represents the shared beliefs, values, and norms of a particular group or community. It functions as a guide to act and filter to react, and it can be analyzed on many levels of discourse, such as meaning, formal structure, sentence syntax, discourse form, argumentation, rhetoric, action and interaction, and through some analytical categories to display the ideological properties of discourse[2]. Ideology is not a fixed or objective reality but rather a social construct that can be contested and negotiated.
In the context of SFL, perception and ideology intersect in the analysis of language use. Language is a social semiotic system that is used to construct and negotiate meaning, and it is influenced by the ideologies of the speakers and the social context in which the language is used. SFL views language as a social semiotic system that is used to produce and exchange meaning between members of a culture through the use of language, signs, and images which stand for or represent things[1].
In summary, perception and ideology are related but distinct concepts within the appraisal framework of Systemic Functional Linguistics. Perception refers to the cognitive process of interpreting and understanding the world, while ideology refers to the shared beliefs, values, and norms of a particular group or community. Both concepts are important in understanding how language is used to construct and negotiate meaning in social contexts.
