|
Visual Evoked Potentials (VEPs) EEG
Time Frame: Baseline, 6 weeks and 24 weeks
|
Visual Evoked Potentials (VEPs) index low-level visual processing and reflect the functional integrity of the visual pathway.
VEPs reflect excitatory (glutamatergic) and inhibitory (GABAergic) activity and may index subgroups of ASD with low-level visual impairments.
VEPs also serve as a control for assessment of higher-order activity in social visual paradigms.
Subjects will be presented with black and white checkerboards that reverse phase at a defined interval.
The order of the VEP and Biomotion paradigms will be counterbalanced.

|
Eye-tracking (ET) Pupillary Light Reflex Task
Time Frame: Baseline, 6 weeks and 24 weeks
|
ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits. Both blocks will include all the tasks but in different orders. The length of individual paradigms ranges from 1 to 8.5 mins. Pupillary Light Reflex (PLR) Task is measured following a stimuli that consist of a central fixation point on a black background that flashes white for 133 milliseconds. The constriction of the pupil in response to a bright flash indexes function of the parasympathetic nervous system. |
Baseline, 6 weeks and 24 weeks
|
Eye-tracking (ET) Static Social Scenes Task
Time Frame: Baseline, 6 weeks and 24 weeks
|
ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits.
Both blocks will include all the tasks but in different orders.
The length of individual paradigms ranges from 1 to 8.5 mins.
Color images depicting 12 different female faces with direct gaze and the same faces with averted gaze will be presented.
Twelve different exemplars from each of five categories (alarm clocks, mobile phones, birds, cars, and shoes) will be used as distracters.
Twelve different slides will each contain six images (one face and five distracters, one from each category) placed at an equal distance from the center of the screen.
Each slide contains a different set of six images, each image being shown only once in the experiment.
This measure examines scanning patterns towards arrays of objects, synthetic stimuli, and faces as well as towards more complex naturalistic (static) scenes.
This task examines complex scene processing and attentional selection.
