Subjective Measures of Cognition (Cognitive Failures) Versus Objective Measures of Performance. Scores are the Group Means with s.e.m in Parenthesis. Higher Stroop and RT Scores=Slower Reaction Times

	Stroop (sec.)	Free Recall	Simple Reaction Time (msec.)	Repeated Digits Task (Detected)
Low CFQ: CFS Controls High CFQ: CFS Controls	101.69 (3.14) 88.48 (3.16) 117.95 (2.40) 89.14 (8.12)	6.26 (0.20) 6.79 (0.23) 6.44 (0.19) 7.41 (0.45)	400.70 (21.73) 320.27 (22.26) 523.25 (16.91) 282.68 (55.02)	11.77 (0.40) 12.68 (0.43) 11.33 (0.32) 14.64 (1.00)
Group Effect:	F(3,409)=19.94, p<0.001	F(3,409)=2.93, p<0.033	F(3,406)=19.398, p<0.001	F(3,403)=4.15, p<0.006
