The ability to integrate and weight information across dimensions is central to perception
and is particularly important for speech categorization. The present experiments investigate …

Frequency selectivity, temporal fine-structure (TFS) processing, and speech reception were
assessed for six normal-hearing (NH) listeners, ten sensorineurally hearing-impaired (HI) …

Songbirds share a number of parallels with humans that make them an attractive model
system for studying the behavioral and neurobiological mechanisms that underlie the …

Manipulations of the sensory environment typically induce greater changes to the
developing nervous system than they do in adulthood. The relevance of these neural …

Natural sounds convey information via frequency and amplitude modulations (FM and AM).
Humans are acutely sensitive to the slow rates of FM that are crucial for speech and music …

Natural sounds can be characterized by their fluctuations in amplitude and frequency.
Ageing may affect sensitivity to some forms of fluctuations more than others. The present …

Objective Independent amplitude and frequency modulation (IAFM) of a carrier tone uses
two different modulating frequencies, one for amplitude modulation (AM) and one for …

Frequency modulation (FM) and amplitude modulation (AM) detection thresholds were
measured at 40 dB sensation level for young (22–28 yrs) and older (44–66 yrs) listeners …

Frequency modulation (FM) and amplitude modulation (AM) detection thresholds were
measured for a 500-Hz carrier frequency and a 5-Hz modulation rate. For AM detection, FM …

The question of how frequency is coded in the peripheral auditory system remains
unresolved. Previous research has suggested that slow rates of frequency modulation (FM) …
