at birth[13], at six months their acuity increases to 1:2, and to 2:3 at approximately 9 to 12 months of age[20,24,25]. Between the third and fourth year, children can discriminate reliably between sets with a 3:4 ratio, and can become sensitive to an adult-like 7:8 ratio at ...
Sixteen undergraduate students (nine males and seven females; mean age 20 y; range: 18–23) were recruited from freshman, sophomore, and junior years at the South China Normal University. All subjects were right-handed, and had normal or corrected-to-normal eyesight and had no history of neu...
To search for candidate neural substrates of Bayesian integration, we modeled the fMRI signal during the decision period starting at the onset of the slider and ending at the participant’s response (Fig. 1a), and consistent with the behavioral analysis, we searched for BOLD responses to the ...
We observed a progressive delay in the age of onset of physical and cognitive function impairment, age-related diseases, and overall morbidity with increasing age. As the limit of human life span was effectively approached with supercentenarians, compression of morbidity was generally observed. [ ...
Here we show that ANS precision measured at preschool, prior to formal instruction in mathematics, selectively predicts performance on school mathematics at 6 years of age. In contrast, ANS precision does not predict non-numerical cognitive abilities. To our knowledge, these results provide the ...
These drought events are potentially associated with the onset of the Little Ice Age or changes in the El Niño Southern Oscillation, with a shift toward more positive Southern Oscillation Index (SOI) values beginning in the fifteenth century74. Several studies have attempted large-scale analyses ...
Sixteen male adult Wistar Kyoto rats were equally divided into two groups: streptozotocin-induced diabetes and age-matched controls. RRIs and SBP were acquired in control rats and the diabetic rats at the onset of hyperglycemia and insulin-treated euglycemia to determine HRV by the ratio of low...
We then jointly estimated the number of selective sweeps, their mean intensity and age in several 1000G African, European and Asian populations. Our estimations of X, found weakly sensitive to demographic misspecifications, revealed very limited numbers of sweeps regardless the frequency of the ...
Here we show that ANS precision measured at preschool, prior to formal instruction in mathematics, selectively predicts performance on school mathematics at 6 years of age. In contrast, ANS precision does not predict non-numerical cognitive abilities. To our knowledge, these results provide the ...
particularly given the growing incidence of age-related macular degeneration. General ophthalmologists and optometrists refer only patients with needs in both eyes, because the pool of patients with a single, central scotoma is much larger than the pool of low vision care specialists can accommodate....
