Four of the Neuropsychological Measures in the Two Groups

	GPT Dominant Hand T-Score	GPT Non-Dominant Hand T-Score	WCST64 Perseverative Errors T-Score	RBANS Visual Spatial Index Standard Score
Control	46.39	44.89	48.65	100.94
SD	11.83	9.81	7.10	12.31
TBI	34.94	36.00	44.94	85.50
SD	7.73	8.47	12.48	14.76
p values	0.0016	0.0063	0.2951	0.0017

Since four of the neuropsychological measures should significant correlations with LZC, we also did a t-test on these four measures between the two subject groups. The results showed that three of them were slightly different.
