Coherent dots will always move in the direction of coherent motion in all frames.298 -Different: Each dot can be either a coherent dot (signal) or incoherent dot (noise) and will be designated randomly (weighted based on the coherence level) at each frame. Only the dots that are designated to be coherent dots will move in the direction of coherent motion, but only in that frame. In the next frame, each dot will be designated randomly again on whether it is a coherent or incoherent dot.299300 Noise Type:301 -Random position: The incoherent dots appear in a random location in the aperture in each frame302 -Random walk: The incoherent dots will move in a random direction (designated randomly in each frame) in each frame.303 -Random direction: Each incoherent dot has its own alternative direction of motion (designated randomly at the beginning of the trial), and moves in that direction in each frame.304305 -------------------306307 1 - same && random position308 2 - same && random walk309 3 - same && random direction310 4 - different && random position311 5 - different && random walk312 6 - different && random direction */313314 var RDK = trial.RDK_type;315316317 /* 318 Shape of aperture319 1 - Circle320 2 - Ellipse321 3 - Square322 4 - Rectangle323 */324 var apertureType = trial.aperture_type;325326 /*327 Out of Bounds Decision328 How we reinsert a dot that has moved outside the edges of the aperture:329 1 - Randomly appear anywhere in the aperture330 2 - Appear on the opposite edge of the aperture (Random if square or rectangle, reflected about origin in circle and ellipse)331 */332 var reinsertType = trial.reinsert_type;333 334 //Fixation Cross Parameters335 var fixationCross = trial.fixation_cross;
