Table 2.

Mean d′, hit rate, and false alarm rate per distractor condition and target position as calculated with the log-linear approach (Hautus, 1995).

	d′		Hit rate		False alarm rate
	M	SD	M	SD	M	SD
Distractor condition
No distractor	1.15	0.27	0.73	0.07	0.30	0.06
High-probability distractor	1.16	0.23	0.74	0.07	0.30	0.06
Low-probability distractor	1.06	0.25	0.73	0.08	0.33	0.08
Target position
High-probability location	0.98	0.54	0.70	0.11	0.34	0.10
Low-probability location	1.17	0.26	0.74	0.07	0.30	0.07
