Recent advances in technology for hyper-realistic visual and audio effects provoke the concern that deepfake videos of political speeches will soon be indistinguishable from authentic video. We conduct 5 pre-registered randomized experiments with N = 2215 participants to evaluate how accurately humans distinguish real political speeches from fabrications across base rates of misinformation, audio sources, question framings with and without priming, and media modalities. We do not find base rates of misinformation have statistically significant effects on discernment. We find deepfakes with audio produced by the state-of-the-art text-to-speech algorithms are harder to discern than the same deepfakes with voice actor audio. Moreover across all experiments and question framings, we find audio and visual information enables more accurate discernment than text alone: human discernment relies more on how something is said, the audio-visual cues, than what is said, the speech content.

This study presents a comprehensive investigation into the correlation between Rare Diseases and Syndromes (RDS) and the dysphagic disorders manifested during childhood and adulthood in affected patients. Dysphagia is characterized by difficulty or an inability to swallow food of any consistency, as well as saliva or medications, from the oral cavity to the stomach. RDS often present with complex and heterogeneous clinical manifestations, making it challenging to develop standardized diagnostic and therapeutic approaches.

A specific deletion on the short arm of chromosome 5 (5p) is the hallmark of the rare genetic syndrome called Cri du Chat Syndrome (CdCS). It causes severe difficulty with swallowing, speech, motor skills, and cognitive deficiencies. These arise from characteristic laryngeal abnormalities and oral-motor dysfunctions.

Introduction: Self-esteem and vocal perception are central aspects of identity and self-presentation, particularly within marginalized communities where voice and self-concept can be deeply intertwined with social acceptance and cultural dynamics. Among Brazilian gay men, generational differences in these areas may reflect broader social changes, shifts in stigma, and evolving notions of masculinity. This study aims to explore these differences, examining how self-esteem and self-assessed vocal descriptions vary across generations, thereby shedding light on specific needs and areas for potential support within these communities.

Recent advancements in computing power and machine learning techniques have facilitated the digitization of new corpora, as well as new methods for studying high-dimensional data. This has enabled empirical investigations of fundamental questions in the social sciences that were previously restricted by technical limitations or data availability. In this note, we introduce a new dataset covering debates in the Norwegian Parliament in the 1945-2024 period.

Inclusive and supportive classroom environments are essential, particularly during political and societal crises such as wars, disinformation, polarization, and rising populism and extremism. While existing research underscores the importance of such environments, few studies comprehensively examine the impact of anti-hate speech prevention programs on classroom dynamics and students' social development. This study addressed this gap by investigating the direct and indirect effects of the HateLess anti-hate speech prevention program on inclusive classroom climate, classroom cohesion, empathy, and self-efficacy among adolescents.
