mrazek et al. mindfulness training and GRE

Introduction to Standardized Testing

  • Millions of college and graduate school applicants take standardized tests (e.g., SAT, GRE) annually.

  • These tests are supposed to measure stability in cognitive capacity predictive of educational and professional success.

  • Test-prep industry is multibillion-dollar, due to the impact of these tests on school admissions.

Cognitive Training and Plasticity

  • Psychological measures like working memory capacity (WMC) are traditionally viewed as fixed abilities.

  • Recent research focused on improving cognitive function through training, emphasizing the need for mechanistic explanations of improvements.

  • Performance enhancements may arise from interventions targeting underlying cognitive processes rather than task-specific strategies.

The Role of Mind Wandering in Cognitive Performance

  • Mind wandering is defined as shifting attention from a task to unrelated thoughts, negatively impacting performance on various measures including WMC and GRE scores.

  • Despite its significance, strategies to mitigate mind wandering have yet to be established robustly.

Mindfulness Training and Cognitive Improvements

  • Study hypothesis: 2-week mindfulness training would reduce mind wandering and enhance cognitive performance (GRE scores and WMC).

  • Findings indicate mindfulness training led to improved GRE reading comprehension and increased WMC; it also reduced distracting thoughts.

  • Performance improvements were mediated by reductions in mind wandering, particularly in participants prone to distraction.

Method of the Study

  • Participants: 48 undergraduate students (26 mindfulness class, 22 nutrition class).

  • Mindfulness training involved focused-attention meditation practices integrated into daily life and included specific exercises.

  • Compared to a control group receiving basic nutrition education, the mindfulness group showed significant improvements in cognitive tests.

  • Assessments included GRE reading comprehension and operation span tasks for WMC.

Results of the Investigation

  • Improvement in GRE scores correlated with prior SAT reading comprehension, validating the ecological relevance of the study measures.

  • ANOVA results showed significant interactions between training conditions and testing sessions, demonstrating mindfulness training's effectiveness.

  • Statistical analysis confirmed significant reductions in mind wandering among those who received mindfulness training.

Implications of Findings

  • Mindfulness training appears to foster enhanced cognitive performance by improving attention focus and reducing mind wandering.

  • Results suggest that cognitive abilities are not as fixed as previously thought; they can be improved through training and practice.

  • Reduced activation of the brain's default network, associated with mind wandering, suggests a neural basis for the improvements seen with mindfulness training.

Conclusion

  • The findings indicate that a brief mindfulness training program can elicit significant enhancements in cognitive abilities and attentional control.

  • Mindfulness may present a viable approach for tackling issues of mind wandering and distraction in various cognitive contexts.

  • Further research is encouraged to explore the long-term effects and mechanisms of mindfulness on cognitive function.
