dc.description.abstract |
Previous research shows that dyslexic readers are impaired in their recognition of faces and other
complex objects, and show hypoactivation in ventral visual stream regions that support word and
object recognition. Responses of these brain regions are shaped by visual statistical learning. If such
learning is compromised, people should be less sensitive to statistically likely feature combinations
in words and other objects, and impaired visual word and object recognition should be expected.
We therefore tested whether people with dyslexia showed diminished capability for visual statistical
learning. Matched dyslexic and typical readers participated in tests of visual statistical learning of pairs
of novel shapes that frequently appeared together. Dyslexic readers on average recognized fewer pairs
than typical readers, indicating some problems with visual statistical learning. These group differences
were not accounted for by differences in intelligence, ability to remember individual shapes, or spatial
attention paid to the stimuli, but other attentional problems could play a mediating role. Deficiencies in
visual statistical learning may in some cases prevent appropriate experience-driven shaping of neuronal
responses in the ventral visual stream, hampering visual word and object recognition. |
