OVERVIEW
- CogScreen-Aeromedical Edition (CogScreen-AE) is a computer-administered and scored
cognitive-screening instrument designed to rapidly assess deficits or changes in
attention, immediate- and short-term memory, visual perceptual functions, sequencing
functions, logical problem solving, calculation skills, reaction time, simultaneous
information processing abilities, and executive functions.
- CogScreen-AE was initially designed to meet the Federal Aviation Administration's
(FAA) need for an instrument that could detect subtle changes in cognitive functioning:
"changes which left unnoticed may result in poor pilot judgment or slow reaction
time in critical operational situations" (Engelberg, Gibbons, & Doege, 1986, p.
lS89).
- CogScreen-AE meets the FAA's requirement for a sensitive and specific neurocognitive
test battery for use in the medical recertification evaluation of pilots with known
or suspected neurological and/or psychiatric conditions CogScreen-AE is not a test
of aviation knowledge or flying skills, but rather a measure of the underlying perceptual
cognitive, and information processing abilities associated with flying (Imhoff &
Levine, 1986).
- CogScreen-AE consists of a series of computerized cognitive tasks, each self-contained
and presented with instructions and a practice segment. The subtests are listed
and described below.
DESCRIPTIONS OF COGSCREEN-AE SUBTESTS
| Subtest |
Description |
| Backward Digit Span (BDS) |
Recall of a sequence of visually presented digits in reverse order.
|
| Math |
Traditional math word problems with multiple choice answer format.
|
| Visual Sequence Comparison (VSC) |
Comparison of two simultaneously presented series of letters and numbers.
|
| Symbol Digit Coding (SDC) |
Substitution of digits for symbols using a key, followed by immediate and
delayed recall of symbol-digit pairs.
|
| Matching to Sample (MTS) |
Immediate recognition for a checkerboard pattern.
|
| Manikin (MAN) |
Mental rotation task requiring respondent to identify the hand in which a
rotated human figure is holding a flag.
|
| Divided Attention (DAT) |
Task employs a visual monitoring task, which is presented alone and in
combination with the Visual Sequence Comparison task.
|
| Auditory Sequence Comparison (ASC) |
Comparison of two series of tone patterns.
|
|
Pathfinder (PF)
|
Visual sequencing and scanning task that requires respondents to sequence
numbers, letters, and an alternating set of numbers and letters.
|
|
Shifting Attention (SAT)
|
Rule-acquisition and rule-application test requiring mental flexibility and
conceptual reasoning.
|
|
Dual Task (DTT)
|
Consists of two tasks, each of which is performed alone and then together as a
simultaneous test. One task is a visual-motor tracking test. The second task is
a continuous memory task involving serial digit recall.
