The Bender Visual-Motor Gestalt Test (abbreviated as Bender-Gestalt test) is a psychological test used by mental health practitioners that assesses visual-motor functioning, developmental disorders, and neurological impairments in children ages 3 and older and adults. The test consists of nine index cards picturing different geometric designs.
The Benton Visual Retention Test is composed of 3 sets, or forms, of 10 designs (each 8.5 × 5.5 in.) that measure the examinee's visual and memory abilities as well as a set of alternate designs for repeated tests. [4] The examinee is given a booklet containing 10 blank pages on which they reproduce the designs.
The dot cancellation test or Bourdon–Wiersma test is a commonly used test of combined visual perception and vigilance. [1] [2]The test has been used in the evaluation of stroke where subjects were instructed to cross out all groups of four dots on an A4 paper.
The Gollin figures test is a psychological test used to assess someone's visual perception. Subjects are shown pictures of common objects: namely five consecutive incomplete line drawings for each picture, from least to most complete, that the subjects need to mentally complete to identify the object drawn.

The Trail Making Test is a neuropsychological test of visual attention and task switching. It has two parts, in which the subject is instructed to connect a set of 25 dots as quickly as possible while maintaining accuracy. [ 1 ]
A psychomotor vigilance task (PVT) is a sustained-attention, reaction-timed task that measures the consistency with which subjects respond to a visual stimulus.Research indicates increased sleep debt or sleep deficit correlates with deteriorated alertness, slower problem solving, declined psychomotor skills, and increased rate of false responses.
Models based on this idea have been used to describe various visual perceptual functions, such as the perception of motion, the perception of depth, and figure-ground perception. [16] [17] The "wholly empirical theory of perception" is a related and newer approach that rationalizes visual perception without explicitly invoking Bayesian formalisms.
An example of the Benton Visual Retention Test. The target stimulus is presented at the top, after a delay participants are asked to recall the correct target stimulus from the list of design cards. The Benton Visual Retention Test is an assessment of visual perception, and visual memory abilities. [8]
