Individual differences in cognitive processing for roughness rating of fine and coarse textures.

Published: November 2019

Previous studies have demonstrated that skin vibration is an important factor affecting the roughness perception of fine textures. For coarse textures, the determining physical factor is much less clear and there are indications that this might be participant-dependent. In this paper, we focused on roughness perception of both coarse and fine textures of different materials (glass particle surfaces and sandpapers). We investigated the relationship between subjective roughness ratings and three physical parameters (skin vibration, friction coefficient, and particle size) within a group of 30 participants. Results of the glass particle surfaces showed both spatial information (particle size) and temporal information (skin vibration) had a high correlation with subjective roughness ratings. The former correlation was slightly but significantly higher than the latter. The results also indicated different weights of temporal information and spatial information for roughness ratings among participants. Roughness ratings of a different material (sandpaper versus glass particles) could be either larger, similar or smaller, indicating differences among individuals. The best way to describe our results is that in their perceptual evaluation of roughness, different individuals weight temporal information, spatial information, and other mechanical properties differently.

Feeling a texture typically involves sliding the fingers of a hand across that surface or rubbing the surface between the thumb and another digit. Texture signals appear to be integrated across the digits of a hand with perceived roughness at one finger swayed in the direction of texture touched by another finger of the same hand. To date, one study has reported similar integrative effects when the pairs of digits belong to different hands.

Background: Speech production is a possible way to monitor bulbar and respiratory functions in patients with amyotrophic lateral sclerosis (ALS). Moreover, the emergence of smartphone-based data collection offers a promising approach to reduce frequent hospital visits and enhance patient outcomes. Here, we studied the relationship between bulbar and respiratory functions with voice characteristics of ALS patients, alongside a speech therapist's evaluation, at the convenience of using a simple smartphone.

MINARO DRS: usability study of a robotic-assisted laminectomy.

Purpose: Although the literature shows that robotic assistance can support the surgeon, robotic systems are not widely spread in clinics. They often incorporate large robotic arms adopted from the manufacturing industry, imposing safety hazards when in contact with the patient or surgical staff. We approached this limitation with a modular dual robot consisting of an ultra-lightweight carrier robot for rough prepositioning and small, highly dynamic, application-specific, interchangeable tooling robots.

Objective: This study aimed to validate the French adaptation of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) for assessing voice disorders in France. The CAPE-V addresses limitations of the GRBAS by providing a more sensitive, standardized approach to evaluating six vocal parameters (overall severity, roughness, breathiness, strain, pitch, and loudness) on three tasks (sustained vowels, sentence reading, and spontaneous speech). The study focused on investigating the intra- and inter-rater reliability, as well as the convergent and discriminant validity of the CAPE-V.

Article Synopsis
  • - This study aimed to classify voice signals in children aged 4 to 16 using narrowband spectrograms and assess their quality through auditory evaluation, focusing on distinguishing between different types of voice signals.
  • - Researchers recorded voice samples from 457 boys and girls, generating spectrograms, having two raters classify the signals, and calculating acoustic measures with PRAAT software, achieving a high level of agreement in classifications.
  • - Results showed that 79% of samples were classified as type 1 voices, with significant differences in certain acoustic measures based on age and sex, providing valuable normative data for understanding and comparing pediatric dysphonia.
