In the pedagogical framework of teaching language skills, the oral medium relies heavily on the complementary dynamics of listening and speaking. Consider the following four advanced theoretical propositions regarding the functions of language, listening comprehension, and oral production: I. Jakobson’s model of language functions identifies the conative function as being primarily speaker-oriented (expressing subjective emotions and attitudes), whereas the emotive or expressive function is strictly addressee-oriented (designed to influence behavior or command actions). II. In transactional spoken discourse (such as buying a ticket or negotiating a business contract), the primary linguistic focus is on the efficient transfer of propositional information and transactional outcomes, whereas interactional spoken discourse (such as casual chatting or social pleasantries) prioritizes interpersonal rapport, social solidarity, and maintenance of social relationships. III. Bottom-up listening processes involve listeners relying on their background knowledge, contextual schema, and global situational expectations to anticipate discourse content, whereas top-down listening processes focus strictly on decoding acoustic signals, phonemic contrasts, and morphemic boundaries sequentially. IV. Speaking tasks designed around communicative language teaching (CLT) frequently utilize information-gap activities and role-plays to encourage pragmatic fluency, sociolinguistic appropriacy, and negotiation of meaning, moving beyond mere mechanical mimicry and rote recitation of dialogs. Identify the option that correctly evaluates the pedagogical, linguistic, and theoretical validity of propositions I, II, III, and IV according to modern second language acquisition theory and Functions of language principles.
