In cognitive psychology, the 'cognitive reserve' hypothesis suggests that intellectually stimulating activities help maintain brain function as people age. Researcher Elena Rostova and her team compared executive function—specifically cognitive flexibility—in older bilingual individuals and older monolingual individuals. The researchers observed that among participants who rarely engaged in mentally challenging hobbies, bilinguals significantly outperformed monolinguals. However, among participants who regularly played musical instruments or solved complex puzzles, monolinguals performed just as well as bilinguals. Given that playing music and solving puzzles stimulate the same neural networks responsible for managing multiple languages, Rostova's team concluded that ______

Which choice most logically completes the text?

  1. A
    older bilinguals who do not engage in challenging hobbies exhibit lower cognitive flexibility than older monolinguals who also do not engage in such hobbies.
  2. B
    older monolinguals who regularly play musical instruments are more likely to successfully learn a second language than those who do not.
  3. for older monolinguals, regularly participating in mentally challenging hobbies can produce cognitive flexibility benefits similar to those associated with bilingualism.Cevap
  4. D
    intellectually stimulating hobbies are the primary factor in preventing all forms of age-related cognitive decline.

Cevap

for older monolinguals, regularly participating in mentally challenging hobbies can produce cognitive flexibility benefits similar to those associated with bilingualism.
The correct option is supported because the passage notes that the performance difference in cognitive flexibility between older bilinguals and older monolinguals disappears when monolinguals engage in hobbies that stimulate the same neural networks as bilingual language management. This directly supports the conclusion that these hobbies offer older monolinguals cognitive flexibility benefits comparable to those of bilingualism.

Adım Adım Çözüm

1
Identify the key premises presented in the text.
The text establishes that bilinguals outperform monolinguals in cognitive flexibility when neither group engages in mentally challenging hobbies, but this performance difference disappears among individuals who regularly engage in activities like playing music or solving puzzles. Additionally, these hobbies stimulate the same neural networks as bilingualism.
Understanding the established facts and their relationships is the first step in drawing a logical conclusion.
2
Analyze the connection between the neural pathways of bilingualism and the hobbies.
Since both managing multiple languages and engaging in these hobbies stimulate the same neural pathways, they should produce similar effects on cognitive flexibility.
Connecting the shared mechanism (neural pathways) explains why the performance difference between the two groups disappears.
3
Determine which choice is directly supported by these premises without requiring external assumptions.
The option stating that mentally challenging hobbies can yield cognitive flexibility benefits for monolinguals similar to those of bilingualism is directly supported.
A valid logical inference on the SAT must flow directly from the premises without introducing speculative or overly broad claims.
