the Profiler Chart
AND GRAPH INTERPRETATION
provides a detailed graphic analysis of how well each student performed
during the tests. The following explanation will help you to interpret
this information so you can get the most from your experience with Profiler.
on an area of the chart to view information about that section.
Data and Norms Group
box in the upper left corner contains your Name, the Date you took the
test, the File name of your score file, and the name of the Norm Group
against which your performance was measured.
uses the Norm Group as the basis for your score. A norm group is a
collection of test data gathered from other drivers, which is used as a
yardstick to rate your test performance. If the norm group is "Your Company,"
your performance is rated against drivers who have taken the test in "Your
Company." If the Norm Group is "National Norms," your performance is measured
against a national cross-section of drivers who have tested on Profiler.
Overall Score and Percentiles
Overall Score on Profiler appears under the logo in the upper right corner.
Overall Score is calculated from all the skill areas that Profiler rates
during a test. Profiler presents your overall score as a percentile. This
percentile is your standing relative to other drivers in your Norm Group.
For example, if your Overall Score is 68, you rank in the 68th percentile
of drivers in your norm group, meaning that you performed better than 68
percent of the drivers in the group.
All scores for the individual skill-area
components are also percentile rankings.
provides a series of charts that identify each skill-area component of
your overall score. The skill ratings are color-coded. Green scores indicate
above-average performance for the norm group. Yellow ratings indicate average
performance. Orange or red ratings indicate below-average performance in
skill areas that may need work.
chart for each skill-area has four scores, labeled P, 1, 2, 3 and 4. These
scores correspond to your performance in the practice lap and on test levels
1 through 4. By displaying your skills over each of the five levels, Profiler
lets you observe how your performance changes as the test becomes more
understand how to improve your Overall Score, you will need to examine
specific skills in the following sections.
target identification scores on the left side of the page rate your ability
to spot visual cues in three general areas of your field of vision, from
far to near.
two-dimensional computer screen represents a three-dimensional driving
view. In this "flattened" perspective, objects toward the center of the
screen correspond to objects in the distance, whereas objects at the edge
of the screen correspond to closer objects that rapidly zip past in your
scores in the "far" area indicate that you are a driver who pays attention
to details "down the road" before they become critical. Looking ahead during
Profiler (and while on the road) is an important skill practiced by good
scores in the medium and near ranges indicate that you respond well and
quickly to sudden unexpected visual cues.
in mind that these scores are percentile rankings. Their significance
is wholly dependent on the norm group against which you are being ranked.
"Directional Scanning" circle in the center of the page rates your performance
in attending to all areas of your visual field (the computer screen).
four scanning directions represent the four directions where visual cues
appear: up, right, down, and left. Your score for each direction is presented
as a percentile: the number in each colored segment represents your score
relative to other individuals in your Norm Group.
your scores are low in a particular direction, you can consciously focus
on events in that direction when you drive Profiler again. Some individuals
have clear directional deficits that can be corrected by practice. If you've
had an accident in the last 3 years, was it from the direction in which
your Directional Scanning Scores were the lowest?
Decision Making scores on the right side of the page are a rating of
how well you attend to more than one thing at a time.
you recall, the P lap has relatively few things happening at the same time,
while level 4 is hectic! If your decision scores are high in the "far"
segment of the display (the center), you are able to see things in advance
and to respond to many things at once. If your decision scores are low
relative to the others in your group, you might be experiencing tunnel
vision. Tunnel vision often occurs when one is agitated or nervous about
driving or piloting. This will improve if you are calmer when you drive.
As any professional driver will tell you, one way to relax and to reduce
target fixation (tunneling) is through practice.
Progress Through Profiler Levels
can observe your progress through the practice lap and each of the 4 levels
in the "Progress" box in the lower left quadrant of the display.
Progress scores over all 5 levels reflect BOTH accuracy and speed of spotting
Target Reaction Speed
Target Reaction Speed box contains scores that rate the speed with which
you reacted to visual cues (other than the brake light), relative to others
in your norm group.
final box on the left shows your Target Accuracy scores.
bars on the left show how accurately you responded to visual cues in all
parts of the screen. The bars on the right show how many times you clicked
the paddles when events were not there. If the scores on the right are
high, you are pressing the paddles too often.
boxes in the center of the display show your steering scores.
Steering Accuracy scores rate your ability to keep your car centered on
the road or in your lane. If this score is low, you may be over-steering
or not steering enough.
Steering Smoothness scores rate how smoothly you steered. Low scores in
this area indicate your steering is too jerky. If your scores are high,
you have good eye-hand control.
Evasive Maneuvers and Radio Calls
Evasive Maneuvers score rates your skill in evading oncoming vehicles in
your lane. The bar on the left shows your Evasion Score, while the bar
on the right shows how often you crashed into oncoming vehicles.
Radio Calls score rates your accuracy at answering calls to your unit.
The bar on the left reflects the calls to your unit that you answered.
The bar on the right reflects responses to non-events, when you pushed
the radio button without being called.
score bars in three boxes on the right bottom of the page rate how well
you responded to the brake lights on the car in front of you. The first
scores represent BOTH the overall accuracy and speed of braking.
second box rates your reaction speed to the brake lights. These speeds
are generally slower than your Target Reaction Speeds because they involve
the large muscle groups in your leg.
Braking Accuracy scores rate how accurately you responded to the brake
lights. The bar chart on the left reflects your performance responding
to the brake lights. The bar chart on the right indicates how many times
you pressed the brake pedal when there was no brake light on the car in
front of you.
your braking scores are high, but your scanning and decision scores are
low, you are likely fixating on the brake light. The next time you drive
Profiler, try to make the brake the secondary task, and pay more attention
to events in all areas of the screen. Experienced and professional drivers
find that braking and lane control become almost automatic, so they can
reserve visual and thinking resources for avoiding trouble spots on the
