Differences in 5 Hz sAM detection thresholds are not attributable to measures of training or attention.

Abstract

<p>(A) Higher sAM detection thresholds in CHLs were not due to better training, as CHLs reached slightly better compentence during training than CTRs, and criterion performance for detection of a fully-modulated sAM did not correlate with sAM detection thresholds for either group. (B) Proficiency with the task during initial testing, measured by d′ levels for fully-modulated sAM, did not explain differences in sAM detection threshold. (C) False alarm rates, a measure of attention, were not different across groups. (D) The number of trials per session, a measure of motivation, also did not explain differences in sAM detection threshold. <i>Black</i>  =  CTR; <i>Orange</i>  =  CHL.</p
