Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes. Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not exist.
ABA is an applied science devoted to developing procedures which will produce observable changes in behavior. [3] [9] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, [10] but it uses principles developed by such research, in particular operant conditioning and classical conditioning.
A random-dot stereogram (RDS) is stereo pair of images of random dots that, when viewed with the aid of a stereoscope, or with the eyes focused on a point in front of or behind the images, produces a sensation of depth due to stereopsis, with objects appearing to be in front of or behind the display level.
A test designed to identify biomarkers associated with autism just became available in most states. The test is meant to help physicians rule out autism in children who have higher likelihoods of it.
Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision . Recovering stereo vision as far as possible has long been established as an approach to the therapeutic treatment of stereoblind patients.
Functional behavior assessment (FBA) is a method developed by applied behavior analysis (ABA) to identify the variables that maintain a problem behavior. Behavior is lawful . Whether it is desirable or undesirable, behavior is controlled by environmental variables.
Example of a Snellen-like depth test Since the Howard-Dolman test described above is cumbersome, stereoacuity is usually measured using a stereogram in which separate panels are shown to each eye by superimposing them in a stereoscope using prisms or goggles with color or polarizing filters or alternating occlusion.

The training protocol is based on the principles of applied behavior analysis. [3] The goal of PECS is spontaneous and functional communication. [3] The PECS teaching protocol is based on B. F. Skinner's book, Verbal Behavior, such that functional verbal operants are systematically taught using prompting and reinforcement strategies that will lead to independent communication.
