Research Abstract

We use the phrases of “finger extension” and “finger extension” with considering that they are on the same level of description. However, our brain may not handle those movements equally. The results of the present study showed that finger flexion and forearm pronation were considered to be more salient. In addition, when moving two joints cyclically, the salient phase in joint movements tend to occur coincidentally.
