AI Article Synopsis

  • Researchers demonstrate that acoustic features, like pitch and pauses, can effectively identify schizophrenia symptoms from a single spoken response.
  • They compare the effectiveness of acoustic features to previously used text-based features in their detection algorithms.
  • Results indicate that acoustic features are more informative for classification, and while adding text features helps a bit, the improvement is minimal.

Article Abstract

We show how acoustic prosodic features, such as pitch and gaps, can be used computationally for detecting symptoms of schizophrenia from a single spoken response. We compare the individual contributions of acoustic and previously-employed text modalities to the algorithmic determination whether the speaker has schizophrenia. Our classification results clearly show that we can extract relevant acoustic features better than those textual ones. We find that, when combined with those acoustic features, textual features improve classification only slightly.

Wild chimpanzees drum on tree buttresses during dominance displays and travel, generating low-frequency sounds that are audible over distances of more than 1 km. Western chimpanzees (Pan troglodytes verus) in the Nimba Mountains of Guinea selectively choose trees and buttresses when drumming, potentially based on their resonant properties, suggesting that these chimpanzees are optimizing their drumming signals. We investigated whether male eastern chimpanzees (Pan troglodytes schweinfurthii) from the Waibira community in the Budongo Forest, Uganda, also show preferences in tree and buttress choice, exploring whether selectivity is a species-wide feature.

Purpose: Parkinson disease (PD) is a progressive neurodegenerative disease. The aim of this study is to investigate the association between acoustic and cortical brain features in Parkinson's disease patients.

Methods: We recruited 19 (eight females, 11 males) Parkinson's disease patients and 19 (eight females, 11 males) healthy subjects to participate in the experiment.

Background: Subclinical leaflet thrombosis (SLT) is a common complication after transcatheter aortic valve replacement (TAVR). Multidimensional CT (MDCT) is the main imaging mortality for the diagnosis of SLT but it enhances the risk of contrast-induced nephropathy. Our study aimed to use an innovative wearable acoustic cardiography (ACG) device to diagnose SLT as an alternative option.

The major-minor mode dichotomy in music perception.

In Western tonal music, major and minor modes are recognized as the primary musical features in eliciting emotional responses. The underlying correlates of this dichotomy in music perception have been extensively investigated through decades of psychological and neuroscientific research, yielding plentiful yet often discordant results that highlight the complexity and individual differences in how these modes are perceived. This variability suggests that a deeper understanding of major-minor mode perception in music is still needed.

Background: The order Rodentia is the largest group of mammals. Diversification of vocal communication has contributed to rodent radiation and allowed them to occupy diverse habitats and adopt different social systems. The mechanism by which efficient vocal sounds, which carry over surprisingly large distances, are generated is incompletely understood.
