Rates of change in pupil and skin conductance responses by task condition at three levels of trait anxiety and absorption

		Anxiety
		Low		Moderate		High
PDR		Intercept (S.E.)	Slope (S.E.)	Intercept (S.E.)	Slope (S.E.)	Intercept (S.E.)	Slope (S.E.)
Absorption	Low	34.52 (3.50)	−2.95 (1.54)	31.45 (2.20)	0.87 (0.67)	28.37 (4.05)	4.70 (1.88)
	Moderate	33.28 (2.20)	−0.60 (0.67)	34.31 (1.85)	−0.21 (0.29)	35.34 (2.22)	0.18 (0.71)
	High	32.05 (3.33)	1.75 (1.44)	37.18 (2.17)	−1.30 (0.65)	42.31 (3.20)	−4.34 (1.37)
SCR
Absorption	Low	87.73 (8.03)	2.18 (1.76)	80.54 (5.80)	7.36 (0.79)	73.34 (9.25)	12.54 (2.22)
	Moderate	83.93 (5.80)	5.38 (0.78)	82.30 (5.24)	5.85 (0.35)	80.66 (5.84)	6.33 (0.81)
	High	80.12 (7.90)	8.57 (1.70)	84.05 (5.79)	4.34 (0.78)	87.98 (7.68)	0.11 (1.63)

All values adjusted for habituation/sensitization; intercepts calculated at stimulus level = high. Anxiety values obtained at −2 (Low), 0 (Moderate), and +2 (High) standard deviations in Spielberger State-Trait Anxiety Inventory-Trait measures; Absorption values obtained at −2 (Low), 0 (Moderate), and +2 (High) standard deviations in Tellegen Absorption Scale measures.

Abbreviations: PDR= pupil dilation response; SCR= skin conductance response; S.E.= standard error
