The concept of an internal forward model that internally simulates the sensory consequences of an action is a central idea in speech motor control. Consistent with this hypothesis, silent articulation has been shown to modulate activity of the auditory cortex and to improve the auditory identification of concordant speech sounds, when embedded in white noise. In the present study, we replicated and extended this behavioral finding by showing that silently articulating a syllable in synchrony with the presentation of a concordant auditory and/or visually ambiguous speech stimulus improves its identification. Our results further demonstrate that, even in the case of perfect perceptual identification, concurrent mouthing of a syllable speeds up the perceptual processing of a concordant speech stimulus. These results reflect multisensory-motor interactions during speech perception and provide new behavioral arguments for internally generated sensory predictions during silent speech production.

The classical view is that perceptual attunement to the native language, which emerges by 6-10 months, developmentally precedes phonological feature abstraction abilities. That assumption is challenged by findings from adults adopted into a new language environment at 3-5 months that imply they had already formed phonological feature abstractions about their birth language prior to 6 months. As phonological feature abstraction had not been directly tested in infants, we examined 4-6-month-olds' amodal abstraction of the labial versus coronal place of articulation distinction between consonants.

Background: Overuse-related intersegmental abnormalities in the spine of competitive alpine skiers are common findings. However, longitudinal changes in intersegmental abnormalities and symptoms throughout adolescence have not been assessed.
Purpose: To longitudinally assess and compare overuse-related spinal intersegmental abnormalities in adolescent competitive alpine skiers over 48 months and to compare magnetic resonance imaging (MRI) findings in asymptomatic and symptomatic skiers.

Swelling, stiffness, and pain in synovial joints are primary hallmarks of osteoarthritis and rheumatoid arthritis. Hyperactivity of nociceptors and excessive release of inflammatory factors and pain mediators play a crucial role, with emerging data suggesting extensive remodelling and plasticity of joint innervations. Herein, we review structural, functional, and molecular alterations in sensory and autonomic axons wiring arthritic joints and revisit mechanisms implicated in the sensitization of nociceptors, leading to chronic pain.

Learning information may benefit from movement: Items that are spoken aloud are more accurately remembered than items that are silently read (the ). Candidate mechanisms for this phenomenon suggest that speaking may enrich or improve the feature content of memory traces, yet research suggests that prior language skill also plays a role. Recent work showed a larger production effect in bilinguals for words in their language (L2) compared to their first language (L1), potentially suggesting that bilinguals engage different or additional linguistic features when speaking L2 compared to L1 words.
