Perceptual Ability Test
The Perceptual Ability Test includes various types of nonverbal visual acuity items. There are six sections to the Perceptual Ability Test. One section covers two-dimensional perception, while the other sections cover three-dimensional perception. It is important that you read and understand the instructions at the beginning of each section. You must pace yourself so that you complete all six sections of the Perceptual Ability Test within the given time frame. You are not permitted to use measuring devices (i.e., pencils and fingers) while taking the Perceptual Ability Test.

Keyhole (apertures) Rules
Prior to passing through the aperture, the irregular solid object may be turned in any direction. It may be started through the aperture on a side not shown.
Once the object is started through the aperture, it may not be twisted or turned. It must pass completely through the opening. The opening is always the exact shape of the appropriate external outline of the object.
Both objects and apertures are drawn to the same scale. Thus it is possible for an opening to be the correct shape but too small for the object. In all cases, however, differences are large enough to judge by eye.
There are no irregularities in any hidden portion of the object. However, if the figure has symmetric indentations, the hidden portion is symmetric with the part shown.
For each object there is only one correct aperture.
Keyhole Method
Top/Front/End Method
3 answers and their mirror reflections
Process of Elimination
Focus on a section to compare size, direction, slope, etc.
Guided Keyhole Examples
Top Front End (view recognition) Rules
The pictures that follow are top, front, and end views of various solid objects.
The views are without perspective. That is, the points in the viewed surface are viewed along parallel lines of vision.
The projection looking DOWN on it is shown in the upper left-hand corner (TOP VIEW). The projection looking at the object from the FRONT is shown in the lower-left corner (FRONT VIEW). The projection looking at the object from the END is shown in the lower-right-hand-corner (END VIEW).
These views are ALWAYS in the same position and are labeled accordingly.
Top Front End Methods
DO NOT USE Line Counting Method
Visualize the object and use process of elimination
Parallel Viewing Projections

Angle Ranking (angle discrimination) Rules
You are to example the four INTERIOR angles and rank each in terms of degrees from SMAL TO LARGE. Choose the alternative that has the correct ranking.
Angle Ranking Method
MacBook
Pacman
Hill
From a distance
Etc…. There are a LOT
If you have problems, try another
HILL Steeper/More Dangerous
Less Steep/Safer
Acute Angle Bigger Smaller
Obtuse Angle Smaller Bigger
Angle Ranking Process of Elimination
Go directly to answer choices
Determine largest and smallest angles
This results in two answers remaining (50/50)
Angle Ranking Examples
Hole Punching (paper folding) Rules
A flat square of paper is folded one or more times.
The broken lines indicate the original position of the paper. The solid lines indicate the position of the folded paper.
The paper is never turned or twisted. The folded paper always remains within the edges of the original square.
There may be from one to three folds in each item. After the last fold a hole is punched in the paper.
Your task is to mentally unfold the paper and determine the position of the holes on the original square. Chose the pattern of black circles that indicates the position of the holes on the original square. There is only one correct pattern for each item.
Hole Punching (paper folding) Method
Modified Grid Method aka Tick-Tak-To Method (Line of Symmetry) Fast, simple, accurate
Solves half holes & invisible holes
4 Rules1. Place X from last diagram onto grid2. Locate axis of symmetry & reflect
shapes over axis3. X’s already on axis are unchanged4. Any X’s present on other side of axis
of symmetry are invisible. Cross out or circle invisible X’s
Hole Punch Examples
Hole Punching: Invisible Hole(s)
Cube Counting Rules
Each figure has been made by cementing together cubes of the same size.
After being cemented each group was painted on all sides EXCEPT FOR THE BOTTOM ON WHICH IT IS RESTING.
The only hidden cubes are those required to support other cubes.
Cube Counting Method
Multiple questions per diagram
Number 0,1,2,3,4,5 on an upside down T chart
Learn all options for each shape for quick tallying
Total tallies = Total cubes. If not, REDO
Create a counting direction rule and ALWAYS FOLLOW IT

Cube Counting Confusion
1 miscount results in:• 3 Cube Changes• 2 Questions Wrong*
Cube Counting Guided Example
In this figure, how many cubes have two of their exposed sides painted?
A. 1 cube
B. 2 cubes
C. 3 cubes
D. 4 cubes
E. 5 cubes
In this figure, how many cubes have four of their exposed sides painted?
A. 1 cube
B. 2 cubes
C. 3 cubes
D. 4 cubes
E. 5 cubes
Pattern Folding (3D form development) Rules
A flat pattern will be presented. This patter is to be folded into a three dimensional figure.
The correct figure is one of the four given at the right of the pattern. There is only one correct figure in each set.
The outside of the pattern is what is seen at the left.
