The Perceptual Ability Test (PAT) is designed to test your
spatial visualization skills, especially your ability to
interpret two-dimensional representations of
three-dimensional objects. These skills will be useful to
you as a dentist as you construct a mental image of teeth
from X-rays, deal with casts and fillings, etc.
The PAT contains a total of 90 questions divided into
six categories, each consisting of 15 questions.
Keyholes
With keyhole questions, you are presented with a 3-D object
and you must determine through which of five openings this
object can pass. It pass through the opening in any
orientation, but it cannot be rotated.
Top-Front-End
This question type presents you with two projections of an
object. You are expected to determine the third.
Angle Ranking
In angle ranking questions, you are presented with four
angles, labled 1-4. You are required to rank the angles in
increasing order.
Hole Punching
In this question type, a square piece of paper is folded
one, two, or three times. Then, one or more holes are
punched at specific locations. You are required to mentally
unfold the paper and determine the locations of the
holes.
Cube Counting
Cube counting questions present you with several stacks of
cubes. Each stack is constructed by cementing together
identical cubes. You are asked to imagine that the stack as
a whole is painted on all sides except for the bottom.
Then, you are asked to determine how many cubes have a
particular number of sides painted.
Pattern Folding
In pattern folding questions, a flat pattern is presented
and you are asked to select the 3-D figure into which it
folds.
