Same example is given below for explicit cursor but with For Loop, the For Loop cursors are more smart as there is no need to declare variables to fetch values in them and no need to open or close or to check whether the pointer is at end of the cursor. Here is the example: DECLARE...

In a cursor-control task in which the motion of the cursor is rotated randomly relative to the movement of the hand, the sensed directions of hand and cursor are mutually biased. In our previous study, we used implicit and explicit measures of the bias of sensed hand direction toward the ...
