Abstract: BACKGROUND Down syndrome (DS) ranks as one of the most common birth defects in the United States. The relaxed filter hypothesis (RFH) asserts that mothers with no previous children but nearing reproductive senescence reduce fetal… read more here.

Abstract: Abstract The matched filter hypothesis proposes that the tuning of auditory sensitivity and the spectral character of calls will match in order to maximize auditory processing efficiency during courtship. In this study, we analyzed the… read more here.

DOI: 10.1080/09524622.2018.1482786
Abstract: ABSTRACT The matched filter hypothesis proposes that the auditory sensitivity of receivers should match the spectral energy distribution of the senders’ signals. If so, receivers should be able to distinguish between species-specific and hetero-specific signals.… read more here.
