A comparison among three measures of cross-spectral processing of amplitude modulation with tonal signals.
Results were obtained from three paradigms used to study cross-spectral processing of envelope modulation [comodulation masking release (CMR), comodulation detection difference (CDD), and modulation detection interference (MDI)]. When tonal carriers separated by two octaves (flanking tone at 1000 Hz and target tone at 4000 Hz) were amplitude modulated at 20 Hz, there was no evidence of a cMR or CDD effect, but there was substantial MDI.
