Fifty-four undergraduate and graduate students participated in the study
Fifty-four undergraduate and graduate students at Guangdong University of Technology participated in this experiment.
27 students were placed in the high-proficiency group
One group was labeled high-proficient English-Chinese bilinguals ( n = 27); all of the students in this group had passed the CET-6.
What they did
Fifty-four Chinese undergraduate and graduate students were divided into high-proficiency (27 students) and low-proficiency (27 students) bilingual groups. Over a 60-minute laboratory session, participants completed a self-report questionnaire and tasks measuring convergent thinking, divergent thinking, cognitive inhibition, and cognitive flexibility.
What they found
The highly proficient bilingual group scored significantly higher on convergent thinking and divergent thinking compared to the low-proficiency group. Furthermore, high bilingual proficiency was linked to faster reaction times in both the cognitive inhibition and cognitive flexibility tasks. Mediation analysis confirmed that cognitive inhibition explained the relationship between bilingualism and convergent thinking, while cognitive flexibility explained the link to divergent thinking.
The limits
What it doesn't show
The study used a cross-sectional design, meaning it cannot prove that learning a second language causes improved creativity or cognitive control, only that they are associated. It also relied on a relatively small sample of Fifty-four university students from a single Chinese institution, which limits how well these results generalize to other cultures or older adults. Additionally, language proficiency was measured via standardized test results and self-reports rather than objective, active language assessments.
Key terms
- Convergent thinking
- A type of cognitive processing focused on finding a single, correct solution to a structured problem.
- Divergent thinking
- The mental process of generating multiple unique ideas, solutions, or possibilities for an open-ended problem.
- Cognitive inhibition
- The ability to suppress irrelevant thoughts, actions, or distracting stimuli to focus on a goal.
- Cognitive flexibility
- The mental capacity to switch between different rules, tasks, or perspectives as situational demands change.
- Mediation analysis
- A statistical method used to determine if the relationship between an independent and a dependent variable is explained by an intermediate variable.
- Stroop effect
- The delay in reaction time that occurs when a person is asked to name the physical color of a word that spells out a different color.

Common questions
Why does bilingualism specifically improve cognitive inhibition?
Constantly speaking multiple languages forces a bilingual person to actively suppress their native language while using their second language, which naturally trains and strengthens their general inhibitory control over time.
What is the difference between convergent and divergent thinking in this study?
Convergent thinking involves logic and focus to find a single correct answer, which was measured using a word association test. Divergent thinking is about broad, creative brainstorming, which was measured by asking participants to draw original pictures from simple lines.
Did the bilingual advantage extend to all aspects of divergent thinking?
No, the highly proficient bilinguals performed better on total creativity, flexibility, and elaboration, but there was no significant difference in fluency or originality between the high- and low-proficiency groups.
How did the researchers measure the participants' language abilities?
They grouped participants based on whether they passed or failed standardized college English exams and had them complete a self-assessment language history questionnaire.
