Mother tongue affects what you see
from Language Magazine
In a recent study, published in Psychological Science, Martin Maier and Rasha Abdel Rahman at the Humboldt University of Berlin examined how native language influences what we consciously perceive. Groups of Greek, German, and Russian speakers (103 people) were shown a rapid series of shapes and were told to look out for a grey semi-circle. This semi-circle appeared alongside a triangle in different shades of blue and green, and participants later reported whether they saw a complete triangle, a slight or strong impression of the shape, or didn't see it at all.
