Table 1.

Mean values of high and low stimulus groups by contour (standard deviation of F0).

		Authentic (Hz)	Play-acted (Hz)	Statistics
Study 1	Low contour	7.03 ± 3.14	8.53 + 3.00	t = 2.07, p > 0.2
	High contour	48.44 ± 13.83	56.93 + 22.39	t = 2.04, p > 0.1
Study 2	Low contour	6.78 ± 3.00	8.27 + 2.99	t = 2.06, p > 0.2
	High contour	48.89 ± 15.24	56.36 + 20.75	t = 2.05, p > 0.1

Mean contour (measured as standard deviation of fundamental frequency) and standard deviation of the selected high and low value recordings for each authenticity category and study. Statistics represent t-tests of the differences between the contour values by authenticity as applied to BOLD contrasts.
