CONSTRAINTS ON GRIP-SELECTION - MINIMIZING AWKWARDNESS

In picking up and manipulating an object, the selection oi an initial grip (overhand versus underhand) often depends on how comfortable the hand and arm will be at the end of the movement. this effect has been called ''end-state comfort'' and seems to be an important constraint i n grip-selection. The present experiment further explored this effect by selecting a task that would ensure a comfortable ending position re gardless of the initial choice of grip. 206 undergraduates picked up a cardboard paper-towel roll from a horizontal position and placed one end down on a table. Analysis showed a clear preference for the overha nd grip, as 78% of the participants chose this grip. In addition, more women preferred the overhand grip than men. The findings indicate tha t people may br sensitive to minimizing awkwardness in both terminal a nd initial positions.
