2. Background No standardized personnel selection procedure for Pioneer crews
Students are often junior enlisted who have attrited from other C schools
UAV training community has unnecessarily high attrition and poor performance
3. Mid-90s, NAMRL developed a psychomotor test (PMT) as a potential selection tool
Began data collection, but funding was subsequently discontinued
In 2002, contacted NAMTRAGRUDET Milton about UAV research Background
4. Discovered that PMT data collection had continued after NAMRL funding ran out
Obtained PMT and training data for 48 students
39 of these were part of the Internal Pilot (IP) curriculum
Analyzed validity of PMT for predicting
training performance
attrition
among IPs and GCSOs(who also receive IP training) Background
5. Pioneer Crew Requirements Minimum crew consists of an external pilot (EP), internal pilot (IP), and a mission commander/ payload specialist (MC)
EP responsible for take-offs, landings, and control of the vehicle when it is within visual range
IP responsible for control of the aircraft when it is beyond visual range
MC responsible for planning and execution of the mission, operation of the payload, and for information gathering during the mission
6. Psychomotor Test (PMT) Overview
7. Psychomotor Test Components Psychomotor Tasks
Stick, Rudder, & Throttle
Horizontal Tracking
Dichotic Listening
Digit Cancellation
Manikin
8. Psychomotor Tasks:Stick, Rudder, and Throttle Three tasks assessing eye-hand and foot coordination
All scored via accumulated pixel errors over test duration
Administered separately and in combination;Stick & Rudder alsoadministered withDLT
9. Horizontal Tracking Task Goal is to keep a square cursor centered in a rectangle
Cursor driven by a function which accelerates as distance from center increases
‘ball on a see-saw’
Requires constant inputs to ‘balance’ the cursor on the center point
10. Dichotic Listening Test Subjects presented a unique string of numbers and letters in each ear simultaneously
Asked to focus on the NUMBERS heard in a designated ear
Designated ear changes 4 times
Test preceded by practice sessions
Score depends solely on accuracy
11. Stick, Rudder, & Dichotic Listening Test
12. Digit Cancellation A different number between 1 and 4 is displayed on the screen
Using a numeric keypad, examinees enter the number displayed
A new value is displayed immediately upon keystroke
Score depends upon speed and accuracy
13. Manikin Test Test of mental rotation
48 drawings of a human figure holding a square in one hand
Depicted right-side up or upside-down, facing toward or away from the viewer
Objective is to determine which hand is holding the square
Score based on speed and accuracy
14. Score Components Combinations of these subtests used to generate four broad score components and one index score:
Psychomotor ability – hand-eye coordination
Multitasking calculation – calculation under multitasking requirement conditions
Multitasking psychomotor – psychomotor performance under under multitasking requirement conditions
Visuospatial ability – ability to perform mental rotations and reversals
Unit-weighted total
15. Results and Discussion
16. Results and Discussion Correlations with training performance
Psychomotor r: .43; p < .01
Multitasking-calculation r: .42; p < .01
Multitasking-psychomotor r: .51; p < .01
Manikin r: .54; p < .01
Index score r: .59; p < .01
17. ScatterplotTraining Performance by Index Score and Attrite Status
18. Results and Discussion Predicting Attrition
Sample attrition rate 15.8% or 6 of 39
Attrite-complete index scores differedt38 = 2.91, p < .01
Mean attrite index score: -.77
Mean complete index score : .13
Existing PMT and its components have demonstrated predictive validity
Implementation will increase trainee performance and reduce training attrition
19. Future Work
20. Options:
Update & implement existing PMT components at one or more sites
PMT almost 10 years old
PMT technology is outdated & needs revision
Field similar prototype, the Automated Spatial & Cognitive Abilities Test (ASCAT)
Developed by NAMRL
ASCAT uses more current technology than PMT
ASCAT needs some updating and transitioning to web-based administration
Web-based platform already in place; adapted test content is all that is needed
21. Automated Spatial & Cognitive Abilities Test (ASCAT) Subtests include
Dichotic listening test (identical to PMT)
Digit cancellation test (improved over PMT)
Block rotation test
Direction identifying test
Control reversal test
22. Task is to rotate the right figure on all 3 axes until its orientation matches the left figure Block Rotation Task
23. Direction Identifying Test
24. Direction Identifying Test
25. Direction Identifying Test
26. Goal: Negate pitch and roll as UAV rotates
Captures ability to manipulate a UAV in different orientations relative to the controller
Similar to Manikin test Control Reversal Test
