Computerized cognitive measures for the PD and control groups.

	PD (𝑛=10)	Control (𝑛=7)	𝑃 value
SRT (s)	0.287 (0.033)	0.283 (0.031)	.816
CRT (s)	0.743 (0.150)	0.674 (0.083)	.293
CRT-C (s)	0.882 (0.167)	0.731 (0.063)	.023
CRT-L (s)	0.850 (0.178)	0.697 (0.062)	.028
CRT-DT (s)	0.877 (0.198)	0.774 (0.128)	.254
CRT-DS (s)	2.109 (0.403)	1.912 (0.127)	.232
DSM (s)	2.362 (0.450)	2.213 (0.229)	.435
SOPT (scores)	2.400 (0.843)	2.000 (0.577)	.295

Note: SRT: Simple Reaction Time; CRT: Choice Reaction Time; CRT-L: Choice Reaction Time Location; CRT-C: Choice Reaction Time Colour; CRT-DT: Choice Reaction Time Distracter; CRT-DS: Choice Reaction Time Distracter with stop signs; DSM: Digit-Symbol Match; SOPT: Self-Ordered Pointing Test. All data are normally distributed and values reported are mean (SD) and 𝑡-test. Significant 𝑃 values are marked in bold.
