Open the original (DOI 10.3389/fpsyg.2015.00466)- What it measures
- Spanish spelling is transparent, meaning each letter or letter pair maps to a fairly consistent sound. English spelling is less regular, so the study's result cannot be carried over to English without further evidence.
- What it does not show
- The authors state the limit themselves. The study does not include English-speaking adults.
