75
Spatial Position
The ability to perceive an object's position in space relative to oneself and the direction in which it is turned
76
Neural Synchrony
If the neurons detecting a vertical line are firing in synchrony with those signaling movement, then these attributes are registered as belonging to the same object
77

78
Figure/Ground Orientation
The determination of what is the displayed against a background and what is the ground
79
Visual Features
What corners, angles or curves are in view
80
Perceptual Constancy
Refers to the fact that we perceive the constant properties of objects in the world (their sizes, shapes and so on)
81
Size Constancy
You correctly perceive the sizes of objects despite the changes in retinal-image size created by changes in viewing distances

117
Executive Control
Can only handle one task at a time and this point obviously puts limits on your ability to multitask
