| RSpan (# correct) | 19.7 (4–34) | 6.1 | 16.8 (5–33) | 7.6 | 1.80 | .076 |
| TRT (% unmasked text) | 59.7 (49–75) | 5.4 | 59.8 (53–74) | 5.2 | 0.08 | .939 |
Note. Data of normal-hearing (NH) listeners from previous studies are also given. Independent t tests were done to compare the groups. LDT = lexical-decision test; WN = word-naming test; VS = vocabulary size test; RSpan = Reading Span test; TRT = text reception threshold test; CI = cochlear implant. NH data were obtained from Kaandorp et al. (2016) for LDT, WN, and VS (n = 72); and from Besser et al. (2012) for TRT and RSpan (n = 55).
