Article Abstract
This study investigates the interactions between musicianship and two auditory cognitive processes: auditory working memory (AWM) and stream segregation. The primary hypothesis is that AWM could mediate a relationship between musical training and enhanced stream segregation capabilities. Two groups of listeners were tested: the first aimed to establish the relationship between the three variables, and the second aimed to replicate the effect in an independent sample. Music experience history and behavioral data were collected from a total of 145 healthy young adults with normal binaural hearing. The AWM task involved the manipulation of tonal patterns in working memory, while the Music-in-Noise Task (MINT) measured stream segregation abilities in a tonal context. The MINT expands measurements beyond traditional Speech-in-Noise assessments by capturing auditory subskills (rhythm, visual, spatial attention, prediction) relevant to stream segregation. Our results showed that musical training is associated with enhanced AWM and MINT performance and that this effect is replicable across independent samples. Moreover, we found in both samples that the enhancement of stream segregation was largely mediated by AWM capacity. The results suggest that musical training and/or aptitude enhances stream segregation by way of improved AWM capacity.

: Speech perception typically takes place against a background of other speech or noise. The present study investigates the effectiveness of segregating speech streams within a competing speech signal, examining whether cues such as pitch, which typically denote a difference in talker, behave in the same way as cues such as speaking rate, which typically do not denote the presence of a new talker. : Native English speakers listened to English target speech within English two-talker babble of a similar or different pitch and/or a similar or different speaking rate to identify whether mismatched properties between target speech and masker babble improve speech segregation.

Some raptors could be considered proper monitors of environmental pollution. We measured heavy metals (Al, Sn, Cu, Cd, Hg, and Pb) and the metalloid (As) concentrations on the 4th primary feather of 49 adult American kestrels (Falco sparverius) to monitor the level of heavy metal pollution in an agriculture landscape of the southern Baja California peninsula. We found As (0.

Concurrent vowel perception experiments have revealed the importance of fundamental frequency (f0) differences in speech stream segregation. Understanding neural processes that support speech streaming using f0 differences remains an active area of perceptual and neurocomputational modeling research. This study simultaneously measured subcortical neural encoding [frequency following responses (FFRs)] and cued vowel identification accuracy of 12 concurrent vowel mixtures with large f0 differences (>8 semitones) to assess whether f0-based neural channel selection predicted perception.

Auditory stream segregation plays a crucial role in understanding the auditory scene. This study investigates the role of tactile stimulation in auditory stream segregation through psychophysics experiments and a computational model of audio-tactile interactions. We examine how tactile pulses, synchronized with one group of tones (high- or low-frequency tones) in a sequence of interleaved high- and low-frequency tones (ABA- triplets), influence the likelihood of perceiving integrated or segregated auditory streams.

Kwame Nkrumah University of Science and Technology (KNUST) established a waste segregation system that provided plastic waste to feed a plastic recycling facility to improve solid waste management in 2017. However, since the establishment of the segregation system, there has not been any assessment to ascertain its efficiency. Hence, this research seeks to assess the efficiency of KNUST's waste segregation system.
