Zorluk: Çok zorNecessary Assumption

Bilinguals consistently exhibit enhanced executive function compared to monolinguals. Many cognitive scientists attribute this to the continuous mental suppression of a secondary language. However, a recent study demonstrates that monolingual individuals who frequently engage in complex strategic board games exhibit a comparable degree of executive function enhancement to lifelong bilinguals. This clearly demonstrates that the constant suppression of a secondary language is not the primary mechanism responsible for the executive function advantage observed in bilingual individuals.

Which of the following is an assumption on which the argument depends?

  1. The enhanced executive function observed in bilingual individuals does not arise from a primary causal mechanism that is fundamentally distinct from the mechanism operating in monolingual board gamers.Cevap
  2. B
    All activities that lead to an equivalent enhancement of executive function do so by triggering the exact same primary cognitive mechanism.
  3. C
    Bilingual individuals do not participate in complex strategic board games at higher rates than monolingual individuals do.
  4. D
    The cognitive mechanisms utilized during complex strategic board games do not involve any form of mental suppression.
  5. E
    The continuous mental suppression of a secondary language is entirely incapable of producing enhanced executive function.

Cevap

The enhanced executive function observed in bilingual individuals does not arise from a primary causal mechanism that is fundamentally distinct from the mechanism operating in monolingual board gamers.
The argument concludes that language suppression is not the primary mechanism for bilinguals' enhanced executive function, based solely on the evidence that monolingual board gamers achieve a comparable enhancement through a different activity. This reasoning assumes that the two groups must be achieving their cognitive enhancements via the same underlying mechanism. If we apply the Negation Test and assume that the primary mechanisms for the two groups ARE fundamentally distinct, the fact that monolinguals get the advantage from board games tells us absolutely nothing about how bilinguals get the advantage. Under those conditions, the argument's conclusion loses all of its supporting evidence and collapses.

Adım Adım Çözüm

1
Identify the core argument structure.
Premise: Monolinguals who play strategic board games achieve the same executive function advantage as bilinguals. Conclusion: Therefore, secondary language suppression is not the primary mechanism for the bilinguals' advantage.
Understanding the premise-to-conclusion link is the essential first step in evaluating the argument's logic.
2
Identify the logical gap.
The author assumes that because a different activity produces the effect in Group B, the originally hypothesized cause must not be the operating mechanism in Group A.
Arguments that use causal evidence from one group to dismiss a cause in another group inherently assume structural similarities between the two groups.
3
Apply the Negation Test to the most likely answer choices.
Negating the correct option yields: 'The executive function advantage in bilinguals DOES arise from a fundamentally distinct mechanism than the one in board gamers.'
The Negation Test is the definitive logical tool for verifying Necessary Assumptions.
4
Evaluate the impact of the negated statement on the stimulus argument.
If the two groups utilize distinct causal mechanisms, the board gamer evidence is rendered completely irrelevant to the bilinguals, destroying the author's conclusion.
A necessary assumption, when logically negated, must cause the argument to collapse.
