Table 1.

The pattern of performance observed for 12 neurologically healthy individuals, reporting the response time (RT, in ms derived from mean log RT), percent accuracy (% Correct) and logit accuracy.

	Left hemifield		Right hemifield		Global target
	Left	Right	Left	Right	Left	Right	Absent
RT	1082	1035	997	1046	1049	1065	1259
% Correct	93.3	96.7	97.1	97.9	91.6	86.4	98.5
Logit	2.63	3.38	3.53	3.82	2.38	1.85	4.21

Logit score is presented because multi-level logistic regression was used in analysis and the logit score better represents the effects to which the analysis was sensitive. Columns indicate each of the six possible target locations shown in Figure 2, as well as performance on trials where the target was absent.
