Derryberry and Reed conducted an experiment to examine the relationship between self-reported . attentional control survey score and actual attentional control. They found that participants with a high survey score could better resist interference in a Stroop-like spatial conflict task. In one of our previous studies Chen and Joyner 2009 we observed a positive although somewhat weak relationship between attentional control survey score and some multitasking performance measures. Participants workload was evaluated using the computer-based version of NASA-TLX Hart Staveland 1988 . Finally a usability questionnaire was used to assess participants reliance on tactile and or visual cueing for the gunnery task when both types of alerts were available. Participants rated their preference on a 5-point scale from 1 to 5 entirely visual-predominately visual- both visual tactile- predominately tactile- entirely tactile . Experimental design The overall design of the experiment is a 2 x 2 x 3 mixed design. The between-subject variable is participants SpA low vs. high . The within-subject variables are Robotics Task type Auto vs. Teleop and AiTR type Baseline- no alerts vs. Tactile alerts only vs. Tactile Visual alerts see Procedure . There were six within-subject conditions Auto-BL baseline No alerts control of a semi-autonomous UGV Teleop-BL No alerts Teleoperating a UGV Auto-Tac Tactile alerts control of a semi-autonomous UGV Teleop-Tac Tactile alerts Teleoperating a UGV Auto-TacVis Tactile alerts Visual alerts control of a semi-autonomous UGV Teleop-TacVis Tactile alerts Visual alerts Teleoperating a UGV The reliability level of the alerts was 100 . However only hostile targets were cued not the neutral targets. The participants had to detect the neutral targets on their own. It .
