Based on the passage, the "poverty of the stimulus" argument relies on which of the following logical premises?

The cultural transmission of language is so intensive that children learn it without needing biological predispositions.

The superficial variations among the world's languages prevent children from accessing a universal grammatical architecture.

The environmental linguistic input a child receives is mathematically insufficient to account for the speed and accuracy of their grammatical mastery.

Children who receive explicit grammatical corrections acquire language slower than those who rely on innate faculties.

According to the passage, modern Neo-Whorfianism differs from early twentieth-century Whorfianism in that the modern approach:

views language as a rigid boundary that dictates what concepts a human is capable of understanding.

aligns perfectly with the Universal Grammar framework regarding the superficiality of vocabulary.

rejects the notion that the human brain possesses any biologically determined structural blueprint.

conceptualizes language as a system that cultivates habitual cognitive focus rather than imposing absolute limits on thought.

Based on the "thinking for speaking" framework described in the final paragraph, how would a language that requires speakers to grammatically distinguish between "older sibling" and "younger sibling" most likely affect its speakers' cognition?

The speakers would lack the universal cognitive faculty necessary to comprehend the generalized concept of a "sibling."

The speakers' cognitive apparatus would become chronically attuned to monitoring and encoding age hierarchies within their social environment.

The speakers would acquire the grammatical rules of their language far more slowly due to the increased complexity of the vocabulary.

The speakers would experience a decrease in their spatial navigational skills, as their attention is diverted to social categorizations.

The author’s attitude toward the "thinking for speaking" model can best be described as:

highly critical of its failure to fully embrace biological determinism.

generally supportive of its ability to reconcile innate cognitive faculties with language-specific psychological conditioning.

cautiously skeptical regarding its lack of empirical evidence in cross-cultural psychology.

dismissive of its reliance on superficial variations in phonetic expression.

Reading Passage

For much of the latter half of the twentieth century, the paradigm of Universal Grammar (UG), championed primarily by Noam Chomsky, dominated the field of theoretical linguistics. UG posits that the human brain is hardwired with an innate, biologically determined structural blueprint for language processing, meaning all human languages share a fundamental, underlying syntactic architecture. The principal justification for this theory was the "poverty of the stimulus" argument, which asserted that children acquire grammatical proficiency too rapidly—and with too few explicit corrections—for language to be merely a learned artifact of cultural transmission. Under the UG framework, the vast structural differences observed among the world's languages were relegated to superficial variations in vocabulary and phonetic expression, while the core cognitive mechanisms underlying human thought were considered universal, insulated from the specific tongue an individual happened to speak. However, in recent decades, the advent of cross-cultural cognitive psychology has catalyzed a resurgence of "linguistic relativity," often termed Neo-Whorfianism, which challenges the UG assumption of cognitive uniformity. Unlike the strict deterministic view of early twentieth-century Whorfianism—which argued that language absolutely constrains the limits of thought—the modern Neo-Whorfian approach posits that structural differences in languages systematically cultivate distinct cognitive habits. Empirical studies on spatial cognition have proven particularly illustrative of this phenomenon. For instance, speakers of aboriginal languages that rely exclusively on absolute cardinal directions (e.g., north, south) rather than ego-centric relative terms (e.g., left, right) demonstrate demonstrably superior dead-reckoning navigational skills during non-linguistic tasks. These findings suggest that the structural demands of a specific language force its speakers to habitually monitor specific environmental variables, thereby subtly sculpting their broader cognitive architecture in ways that UG’s biological determinism fails to predict. Consequently, contemporary psycholinguists are increasingly moving toward a synthetic theoretical framework often referred to as "thinking for speaking." This model concedes the UG premise that foundational cognitive faculties are innate and universally human, but it emphasizes that the neurological act of organizing thought into communicative speech requires individuals to selectively attend to the specific conceptual categories their language mandates. If a language obligates a speaker to explicitly mark the evidential source of information (e.g., whether an event was witnessed directly or heard via hearsay), the speaker’s cognitive apparatus becomes chronically attuned to source-monitoring. Thus, while language may not strictly dictate the absolute parameters of human thought, it acts as a pervasive cognitive filter, systematically directing attention and shaping how different linguistic populations encode, retrieve, and interpret reality.
