PDF This study investigated whether movements that were “imaged” or “imagined” to be executed involved a build up of preparatory activation in brain structures in a similar way as movements that were actually executed. By using a loud startling acoustic stimulus, we are able to elicit pre-planned movements if they…
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…
PDF This study looked at whether giving learners control over if (and when) they received feedback affected learning of a new task. The main finding is that learners who were able to choose to receive feedback after a trial performed better in retention and transfer. This suggests that the decision to…
PDF This study investigated the entirety of the timecourse of cortico-spinal excitability changes during a reaction time task – from the time in between trials, and throughout the foreperiod and response interval. The results show a pattern of increase in excitability that occurs just after the “get ready” signal which…
