The spontaneous emergence of Nicaraguan Sign Language (ISN) in the late twentieth century provides an unprecedented window into the mechanics of human language acquisition, particularly regarding the debate over innate grammatical structures. When a national school for the deaf was established in 1977, it brought together dozens of deaf children who had previously communicated only via idiosyncratic 'home-signs' within their hearing families. This initial group, known as the first cohort, rapidly developed a rudimentary pidgin to communicate. However, linguistic analysis reveals that this early system lacked discrete morphology; the first cohort utilized holistic, unsegmented gestures to convey complex events, a practice they maintained even after decades of continuous linguistic interaction.

The transformative leap in ISN's structural complexity occurred solely with the arrival of the second cohort—younger children who entered the school in the 1980s and were exposed to the first cohort's pidgin. Unlike their predecessors, these younger students intuitively decomposed the holistic gestures into discrete, sequentially recombinable elements, spontaneously inventing a spatial grammar with specific verb agreements. Neurological imaging corroborates this behavioral divide: when signing, second-cohort individuals exhibit neural activation strictly localized to the classic left-hemisphere language centers. In contrast, first-cohort signers show robust activation in regions primarily associated with broad narrative memory and visual-spatial processing.

Crucially, psycholinguistic studies of ISN suggest that this structural bifurcation is not merely a product of chronological arrival time, but rather of developmental timing. Researchers have established that the neurological window for natively acquiring discrete morphological structures—the hallmark of a fully formed grammar—closes abruptly around age twelve. Consequently, individuals who were exposed to the school's linguistic environment after this developmental threshold universally defaulted to the unsegmented, holistic strategies of the initial pidgin, irrespective of the structural complexity of the signing environment they entered.

Based on the passage, which of the following can be most reasonably inferred regarding a deaf student who first enrolled in the national school for the deaf at age fourteen during the late 1980s?

  1. A
    They successfully acquired discrete morphological structures due to their direct immersion in the structurally complex environment created by their younger peers.
  2. Their neural activation during signing would most likely involve brain regions associated with broad narrative memory rather than being strictly localized to left-hemisphere language centers.Cevap
  3. C
    Their neural activation would be strictly localized to classic left-hemisphere language centers, reflecting their continuous exposure to a fully formed spatial grammar.
  4. D
    They eventually transitioned to using discrete morphology after several decades of continuous linguistic interaction with native signers.
  5. E
    Their developmental timing caused them to abandon both the school's pidgin and spatial grammar in favor of their original idiosyncratic home-signs.

Cevap

Their neural activation during signing would most likely involve brain regions associated with broad narrative memory rather than being strictly localized to left-hemisphere language centers.
The correct answer accurately synthesizes three distinct details from the passage. First, the neurological window for acquiring discrete morphology closes at age twelve. Second, anyone exposed after this age defaults to holistic, unsegmented gestures (the initial pidgin) regardless of their environment. Third, individuals using these holistic gestures exhibit neural activation in areas associated with broad narrative memory, contrasting with the strictly left-hemisphere activation of those using discrete morphology. Since the student was fourteen, they would use holistic gestures and thus display the corresponding narrative memory brain activation.

Adım Adım Çözüm

1
Analyze the specific conditions of the student described in the question stem.
The student arrived in the late 1980s (the era of the second cohort) but was fourteen years old upon enrollment.
Identifying the student's arrival era and age is necessary to apply the conditional rules established in the text.
2
Apply the passage's developmental rule regarding age to the student.
Because the student was fourteen, they were past the developmental threshold (age twelve). Therefore, they 'universally defaulted to the unsegmented, holistic strategies of the initial pidgin,' despite arriving during the 1980s.
The passage emphasizes that developmental timing overrides chronological arrival time.
3
Link the resulting linguistic behavior to its neurological correlate described earlier in the passage.
The text states that first-cohort signers, who also use holistic, unsegmented gestures, 'show robust activation in regions primarily associated with broad narrative memory' rather than being strictly localized to the left hemisphere.
Answering the inference question requires synthesizing the student's predicted behavior with the corresponding neurological profile provided by the author.
