Oral applause sign in progressive supranuclear palsy.

The applause sign (AS) is a recognized phenomenon observed in progressive supranuclear palsy (PSP) and other neurological conditions where individuals produce over three claps following a request to clap only thrice after a demonstration. In this study, we introduced a novel linguistic phenomenon termed the oral applause sign (OAS) associated with the AS. The OAS is characterized by increased repetition counts of Japanese repetitive onomatopoeic words, such as uttering "pata-pata-pata" instead of the expected "pata-pata.

Social media is marked by online firestorms where people pile-on and shame those who say things perceived to be offensive, especially about politically relevant topics. What explains why individuals engage in this sort of sanctioning behavior? We show that two key factors help to explain this pattern. First, on these topics, both offensive speech and subsequent sanctioning are seen as informative about partisanship: people assume that those who say offensive things are out-partisans, and those who criticize them are co-partisans.

This study introduces a novel method for predicting the Big Five personality traits through the analysis of speech samples, advancing the field of computational personality assessment. We collected data from 2045 participants who completed a self-reported Big Five personality questionnaire and provided free-form speech samples by introducing themselves without constraints on content. Using pre-trained convolutional neural networks and transformer-based models, we extracted embeddings representing both acoustic features (e.

Background: Incorporating patient and public involvement (PPI) in research is crucial for ensuring the relevance and success of studies, yet it remains significantly underutilised in surgical research.
Main Body: This commentary presents insights from our neurosurgical research team's experience with establishing and working with a PPI group called "Science for Tomorrow's Neurosurgery" on research regarding novel intra-operative optical imaging techniques. Through collaboration with patient-focused charities, we have successfully incorporated patient perspectives into our work at each stage of the research pipeline, whilst adhering to core PPI principles, such as reciprocal relationships, co-learning, partnerships, and transparency.
Purpose: The static and dynamic soft tissue changes resulting in hypopnea and/or apnea in the subjects with obstructive sleep apnea (OSA) occur in the upper airway, which also serves as the voice or speech tract. In this study, we looked for the Voice Handicap Index-10 (VHI-10) and Voice-Related Quality of Life (V-RQOL) scores in addition to perturbation and formant values of the vowels in those with snoring and OSA.
Methods: Epworth Sleepiness Scale (ESS), STOP-Bang scores, Body-Mass Index (BMI), neck circumference (NC), modified Mallampati Index, tonsil size, Apnea-Hypopnea Index, VHI-10 and V-RQOL scores, perturbation and formant values, and fundamental frequency of the voice samples were taken to evaluate.
