A TextDisplay object is presented and the subject is asked to
estimate the location of a previous stimulus. The TextDisplay is
configured with a 0 Duration so that InLine script will execute during
The InLine script is a loop that will run until a response is received.
Inside the loop, the current time is constantly monitored. Every
25ms, the mouse coordinates are logged as attributes, along with

Afterwards, the attributes created are used to present a replay
of the subject's path. A Canvas object is used to draw a circle
representing each set of coordinates logged. An outlined circle
is drawn at the end of the replay to indicate the response
coordinates. The subject can skip this replay by pressing the left
