FLAP Trial Design

4Treatment groups
Experimental Treatment
Group I: Condition 4: Combination trainingExperimental Treatment1 Intervention
In Condition 4, investigators combine the elements of Conditions 1-3. The investigators test the extent to which a combined training gives rise to the joint benefits of each training individually, or integrative benefits potentially surpass the benefits of the individual training alone. The visual sensitivity task from Condition 1 will alternate across blocks with the spatial integration task from Condition 2, using the timing of targets and location switches from Condition 3; Gabors or contours are used as targets instead of the red- circle in Condition 3 and a fixation point is presented instead of distractors to maintain a similar stimulus configuration as Conditions 1 and 2.
Group II: Condition 3: Training spatial attentionExperimental Treatment1 Intervention
A key attribute of most real-world visual tasks is that individuals alternate shifting and holding attention and eye movements to different objects in the visual field while searching for and discriminating possible sources of visual information. To train this, investigators will implement a task structure that requires participants to alternate between holding and switching attention and making targeted eye movements. The basic task is to press a key whenever a red circle appears in a series of other colored circles, with a target presented every 2 to 4s. Participants must maintain vigilance for relatively long periods, detect objects in the near periphery, switch attention based upon exogenous and endogenous cues, and make eye- movements to move areas of spared vision to those locations. These are aspects of attention and eye movements not incorporated in Conditions 1 and 2.
Group III: Condition 2: Training spatial integrationExperimental Treatment1 Intervention
Most visual tasks involve integrating features to discriminate objects, therefore requiring brain areas that can integrate features from multiple receptive fields from early visual areas. Thus spatial integration involves what investigators refer to as mid-level vision. Spatial integration is a particular concern in developing a PRL since an area of the visual periphery that is best suited to discriminate a simple visual feature may not be appropriate to integrate information across objects, such as in reading or recognizing facial identity or expression. Investigators address this issue with a targeted spatial integration training approach developed by MPI Seitz and based on contour integration tasks used in previous PL studies to train mid-level visual processes. Target stimuli consist of contours formed by spaced Gabors. Difficulty of detecting the target is manipulated by varying orientation jitter of Gabors making up the target.
Group IV: Condition 1: Training visual sensitivityExperimental Treatment1 Intervention
A standard Perceptual Learning approach to train early visual processes of discriminating the orientation of Gabor patches presented at threshold- level contrast. Preliminary data, using this method, in normally seeing and MD participants show both feasibility and preliminary evidence that this training gives rise to improvements in acuity.
