Attention Deficits in Stroke Patients: The Role of Lesion Characteristics, Time from Stroke, and Concomitant Neuropsychological Deficits

Table 5

Mean RTs and errors for each attention measure as a function of laterality and presence of neglect (N⁺ = presence and N⁻ = absence) or aphasia (Aphasia⁺ = presence and Aphasia⁻ = absence); SDs are presented in brackets.

	RHL			LHL
	N^+ ()	N^- ()	N^+ vs. N^- comparison	Aphasia^+ ()	Aphasia^- ()	Aphasia^+ vs. aphasia^- comparison
Alertness without warning (RTs)	460 (154)	364 (114)		349 (177)	308 (70)
Alertness with warning (RTs)	451 (150)	349 (104)		334 (167)	302 (87)
Go-No Go (RTs)	772 (141)	674 (135)		722 (171)	646 (83)
Go-No Go (False responses)	5.5 (6.7)	4.1 (5.3)		3.6 (3.7)	2.4 (1.9)
Divided Attention (RTs)	904 (154)	852 (197)		829 (147)	780 (112)
Divided Attention (omissions)	13.5 (6.3)	9.1 (7.4)		5.2 (4.0)	4.1 (3.8)
