SNR50 =Signal-to-noise ratio for 50% correct; LP =Low predictability sentences; ZP =Zero-predictability sequences, PPVT =Peabody Picture Vocabulary Test; TROG-2 =Test of Reception of Grammar, Nonword =Automated Working Memory Assessment (AWMA) Nonword Recall Subtest; Dot =AWMA Dot Matrix Subtest; Counting =AWMA Counting Recall Subtest; Odd =AWMA Odd-one-out subtest. Correlations are based on raw scores.
