Hypothesis
Do dyslexic teenagers experience postural instability when performing a Stroop dual task?
Conclusion
The study found no evidence of primary posture deficits in dyslexic teenagers during the Stroop test.
Supporting Evidence
- Dyslexics displayed shorter cancellation time for the medium frequency band for all tasks.
- No group effect was found for any of the parameters of posture.
- Postural control in quiet stance requires cognitive resources.
- Complex tasks like the flexibility Stroop task require more energy to maintain postural stability.
- Wavelet analysis revealed differences in spectral power related to cerebellar control.
Takeaway
This study looked at how well teenagers with dyslexia can stand still while doing a tricky word game, and it turns out they can do just as well as their friends without dyslexia.
Methodology
The study involved 27 teenagers (15 dyslexics and 12 non-dyslexics) performing three tasks while their postural control was measured using a force platform.
Potential Biases
Potential bias in participant selection as all subjects were recruited from a single school.
Limitations
The study's sample size was small and limited to one school, which may not represent the broader population of dyslexic teenagers.
Participant Demographics
27 teenagers aged 14-17 years, including 15 dyslexics (3 females, 12 males) and 12 non-dyslexics (3 females, 9 males).
