Table 1.

Effects of different training type by test type, presented in gain in percentage points (and SD).

	MOST OVERLAP
Test	ST group	MT group	Control group
Single-Talker 4AFC test	17.8 * (10.2) +++	11.6* (10.9)	2.8 (7.3)
Multi-Talker 4AFC test	11.4 * (12.5) ++	14.7 * (10.5) ++	5.7 (13.1)
Novel-Talker 4AFC test	10.7* (10.5)+	8.0* (12.0)+	7.2* (10.4)+
Iowa Sentences test	1.4 (10.5)	−0.9 (8.3)	−2.5 (7.5)
			LEAST OVERLAP

Note. Bolded results indicate the findings for which a significant difference between the groups could be found. Plus signs (+, ++, +++) highlight the increased degree of overlap: more plus signs reflect greater overlap. ST = Single-Talker; MT = Multi-Talker; 4AFC = four-choice discrimination task.
