PDF This paper investigated whether an additive model of activation or a horse-race model would be a better fit for data showing that reaction times are facilitated to a greater degree than would be expected when a startling stimulus presented after the typical “go” signal. Abstract: When a startling acoustic…
PDF This study is a replication of a previous experiment that investigated how movement-related brain activation changes as a go-stimulus approaches in time. The previous experiment used a startle to show that activity increased in short time prior to the go-signal. However, startle activity was not reported, so this was only…
In this study subjects performed a bimanual coordination task, where spontaneous transitions between states is observed at higher oscillation frequencies. For example, when limbs are moved in a parallel fashion (like windshield wipers on a car) a transition is seen at faster speeds whereby subjects spontaneously change to performing mirror-symmetrical…
