hard · MCAT psych-soc

A researcher studies a sample of bilingual immigrants and finds that those who report frequently switching between their heritage language and the host-country language show smaller decrements in performance on the Stroop task than monolingual controls. The researcher concludes this reflects superior executive control. A reviewer counters that the finding may instead reflect a confound rooted in how the sample was assembled.

Which feature of the study design, if true, would most directly support the reviewer's alternative explanation rather than the researcher's?

  1. The bilingual participants were recruited from a competitive graduate program, whereas monolingual controls were recruited from the surrounding community
  2. The Stroop task was administered in the host-country language for both groups, equating the linguistic demands of the measure itself
  3. Bilingual participants self-reported their frequency of language switching using a validated daily-experience questionnaire
  4. The smaller Stroop decrement among frequent switchers held even after statistically controlling for age and years of education
