The developmental pattern of concurrent synaptogenesis in rhesus monkeys is consistent with a straightforward model of relations between brain and cognitive development. Concurrent synaptogenesis is hypothesized to lay the primary cortical foundation for a series of developmental levels in middle infancy that have been empirically documented in…

This study compared the batting swing of two skilled congenitally blind beep baseball players to a perfect kinetic-link model for the batting skill. It found that the subjects used a modified batting technique and that there was an inverse relationship between the subjects' performances and the kinetic-link model. (Author)
