Experiment Author: David Frank
A ball is launched from left to right bouncing once along the way. Use the mouse to move a paddle into position to intercept the ball and click the left mouse button to lock in that position before the ball reaches a deadline. In Phase 1 the participant must click the paddle into position before the ball reaches the red line. In Phase 2 the participant must click the paddle into position before the ball reaches the gray line.
In this version the participant receives repeated trajectories throughout Phase 1 and 2 before being given occasional new trajectories in Phase 3. This experiment presents a large number of trials.
This program is designed to run at 1920 X 1080 resolution. The stimuli move in pixels units, NOT percentages. It will run at other resolutions, but the stimuli will be different as they bounce off the edges of the screen. The task may become easier or more difficult. The stimuli may go off the screen or bounce multiple times.
