New Research published on Neuropsychologia!

Congratulation to Giovanni, Marco and David who just published a new paper on Neuropsychologia!

Anobile, G., Cicchini, G. M., Gasperini, F. & Burr, D. (2018). Typical numerosity adaptation despite selectively impaired number acuity in dyscalculia, Neuropsychologia, PDF

It has been suggested that a core deficit of the “number sense” may underlie dyscalculia. We test this idea by measuring perceptual adaptation and discrimination thresholds for numerosity and object size in a group of dyscalculic and typical preadolescents (N=71, mean age 12). We confirmed that numerosity discrimination thresholds are higher in evelopmental dyscalculia, while size thresholds are not affected. However, dyscalculics adapted to numerosity in a similar way to typicals. This suggests that although numerosity thresholds are selectively higher in dyscalculia, the mechanisms for perceiving numerosity are otherwise similar, suggesting that that have a similar, but perhaps noisier, number sense.
