Table 4.

Correlations (with 99.5% confidence intervals) for thought-report ratings from subjects in the depth-probe condition, with thought reports treated either as continuous 1–5 ratings (first for subjects’ mean ratings and second for subjects’ standard deviation of ratings) or as dichotomized on-task versus off-task reports, in the SART and flanker task

Correlation	Depth rating continuous (1–5), rating M	Depth rating continuous (1–5), rating SD	Depth rating dichotomized TUT rate (rating ≥ 3 = TUT)
SART × Flanker Rating	r(267) = .65 [.54, .74]	r(267) = .52 [.38, .63]	r(267) = .65 [.54, .74]
SART Rating × SART DSSQ	r(222) = .36 [.19, .51]	r(222) = .23 [.05, .40]	r(222) = .36 [.19, .51]
Flanker Rating × Flanker DSSQ	r(222) = .33 [.15, .49]	r(222) = .31 [.13, .47]	r(222) = .36 [.19, .51]
SART Rating × Executive Control	r(267) = −.24 [−.39, −.07]	r(267) = −.24 [−.39, −.07]	r(267) = −.22 [−.38, −.05]
Flanker Rating × Executive Control	r(267) = −.10 [−.27, .07]	r(267) = −.15 [−.31, .02]	r(267) = −.10 [−.27, .07]
SART Rating × Distracted-Restless	r(203) = .09 [−.11, .28]	r(203) = .19 [−.01, .37]	r(203) = .08 [−.12, .27]
Flanker Rating × Distracted-Restless	r(203) = .13 [−.07, .32]	r(203) = .18 [−.02, .36]	r(203) = .11 [−.09, .30]
SART Rating × Pos. Daydreaming	r(203) = .02 [−.18, .21]	r(203) = .08 [−.12, .27]	r(203) = .03 [−.17, .22]
Flanker Rating × Pos. Daydreaming	r(203) = .18 [−.02, .36]	r(203) = .16 [−.04, .34]	r(203) = .17 [−.03, .35]
