Social‐valence‐related increased attention in rett syndrome cynomolgus monkeys: An eye‐tracking study

The cognitive phenotypes of Rett syndrome (RTT) remain unclarified compared with the well‐defined genetic etiology. Recent clinical studies suggest the eye‐tracking method as a promising avenue to quantify the visual phenotypes of the syndrome. The present study explored various aspects of visual attention of the methyl‐CpG‐binding protein 2 gene mutant RTT monkeys with the eye‐tracking procedure. Comprehensive testing paradigms, including...
