Imaging techniques enable decisive step toward development of novel hearing prostheses
What The Study Did: This review of 125 U.S.-based clinical trials that investigated the management of hearing loss assessed representation in the trials by race/ethnicity and sex.
Plenty of people struggle to make sense of a multitude of converging voices in a crowded room. Commonly known as the "cocktail party effect," people with hearing loss find it's especially difficult to understand speech in a noisy environment. New research suggests that, for some listeners, this may have less to do with actually discerning sounds. Instead, it may be a processing problem in which two ears blend different sounds together - a condition known as binaural pitch fusion.
What The Study Did: The association between hearing loss and level of physical activity among U.S. adults ages 60 to 69 was analyzed in this study.
The brain's auditory system tracks the speed and location of moving sounds in the same way the visual system tracks moving objects. The study recently published in eNeuro lays the groundwork for more detailed research on how humans hear in dynamic environments.
Researchers from the HSE Center for Language and Brain have, for the first time, described the language abilities of Russian children with Autism Spectrum Disorder (ASD) at all linguistic levels (e.g., phonology, lexicon, morphosyntax, and discourse), using a language test that takes into account the psycholinguistic variables most relevant for Russians. The study was published in Journal of Autism and Developmental Disorders.
According to a linguistic survey report, people often confuse the pronunciation of /hi/ with that of /si/ in the dialect of Tokyo and the Tohoku region of Japan. A team of researchers at Toyohashi University of Technology and the National Institute for Japanese Language and Linguistics (NINJAL) found that the confusion is resulted from the articulation of the tongue varying in the transverse direction while the tongue tip is positioned at the same place of articulation.
Researchers from Germany and Russia developed new method to understand how the brain builds associations between previously unrelated words. Method can help patients in disorders of consciousness.
Scientific understanding of the brain regions responsible for speech and communication is limited. Consequently, knowledge of how to improve challenges such as speech impediments or language acquisition is limited as well. Using an ultra-lightweight, wireless implant, a University of Arizona team is researching songbirds - one of the few species that share humans' ability to learn new vocalizations - to improve scientific understanding of human speech.
People are adept at discerning most of the different emotions that underlie screams, such as anger, frustration, pain, surprise or fear, finds a new study by psychologists at Emory University. Screams of happiness, however, are more often interpreted as fear when heard without any additional context, the results show.
