Table 2.

The mean and standard deviation of absolute error, relative error, and displacement for the anterior–posterior dimension signal (X).

	Absolute error (mm)	Relative error (%)	Displacement (mm)
Variable	M (SD)	M (SD)	M (SD)
Participant	1.08 (0.37)	15.14 (1.57)	5.96 (1.93)
Pellet
MM vs. MI (1)	0.21 (0.11)	7.49 (3.58)	3.03 (1.61)
ChA vs. MI (2)	1.11 (0.50)	16.26 (5.70)	6.10 (2.46)
ChC vs. MI (3)	1.16 (0.48)	16.65 (5.65)	6.31 (2.34)
ChG vs. MI (4)	1.71 (0.70)	18.71 (6.18)	8.39 (3.11)
ChR vs. MI (5)	1.25 (0.63)	16.60 (5.62)	6.52 (2.76)
Post hoc		1 < all chin; 4 > 2, 3, 5
Task
Word (1)	1.06 (0.65)	15.88 (5.12)	6.45 (2.66)
Sentence (2)	0.79 (0.36)	9.37 (2.65)	8.05 (2.93)
Paragraph (3)	0.76 (0.38)	6.21 (1.83)	11.63 (1.91)
Post hoc		3 < 1, 2; 1 > 2

Note. Displacement values are the linear distance (maximum-minimum position) across the entire file for each pellet that is being compared to MI. Average error estimates for the task and participant variables do not include the results of MM versus MI. The number in parentheses after each row beneath “Pellet” and “Task” refers to the number used for illustrating significant differences in the subsequent row titled “Post hoc.”
