Biography:
My current research is focused in the area of cognitive science and combines systematic literature analysis and experimental methods. I investigate the effects of various interventions on executive functions in healthy individuals, including cognitive training, implicit approaches, as well as their combination. In my work, I aim to improve methodological standards by estimating and correcting for sources of bias, along with striving for greater clarity in conceptual definitions.

Examination of computer-based programs and non-computerized techniques for improvement of cognitive functioning and verification of reliability of measurements targeting executive functions
Description:
One of the goals of this project is to summarize the existing literature on computerized and non-digital cognitive training programs through a comprehensive meta-analysis, evaluating their effectiveness in enhancing executive functions (EFs) in healthy individuals. The analysis focuses on both near- and far-transfer effects, examining impacts on task-based measures of lower-level EFs (e.g., working memory) as well as higher-level domains (e.g., problem-solving). The study will also investigate how various factors — such as training schedule, type of control group, participant age, and task characteristics — influence the intervention outcomes.
In a follow-up phase, findings from the meta-analysis will be further examined in a randomized controlled trial with a healthy adult sample. The project will also evaluate the test-retest reliability of several widely used EF tasks to ensure the robustness of outcome measures. Finally, we will also carefully explore a wide range of alternative and indirect approaches believed to enhance executive functioning — such as meditation, physical activity, martial arts, breathing exercises and others.
Key research topics:
- Meta-analysis on EF transfer effects after digital and non-digital cognitive training
- Test-retest reliability study of EF tasks
- Randomized controlled trial in healthy adults
- Systematic exploration of implicit methods of cognitive enhancement
