v Visual discrimination. A child’s ability to match or determine exact characteristics of two forms when one of the forms is among similar forms. (i.e what is different, find the same).
v Visual memory.A child’s ability to remember for immediate recall (after four or five seconds) all of the characteristics of a given form, and being able to find this form from an array of similar forms.
v Visual-spatial relationships.A child’s ability to determine, from among five forms of identical configuration, the one single form or part of a single form that is going in a different direction from the other forms. (copying shapes from one item to another)
v Visual form constancy. A child’s ability to see a form, and being able to find that form, even though the form may be smaller, larger, rotated, reversed, and/or hidden.
v Visual sequential memory.A child’s ability to remember for immediate recall (after four or five seconds) a series of forms from among four separate series of forms. (remembering telphone numbers)
v Visual figure-ground.A child’s ability to perceive a form visually, and to find this form hidden in a conglomerated ground of matter.
v Visual closure.A child’s ability to determine, from among four incomplete forms, the one that is the same as the stimulus form (i.e., the completed form).
