Psychophysical assessment of color vision with the Cambridge Color Vision Test in unilateral functional amblyopia.

Arq Bras Oftalmol

January 2025

Research Nucleus in Neuroscience and Behavior and Applied Neuroscience, Universidade de São Paulo, São Paulo, SP, Brazil.

Purpose: Amblyopia is a cortical neurological disorder caused by abnormal visual experiences during the critical period for visual development. Recent works have shown that, in addition to the well-known visual alterations, such as changes in visual acuity, several perceptual aspects of vision are affected. This study aims to analyze and compare the effects of different types of amblyopia on visual color processing and determine whether these effects are correlated with visual acuity.

The near-miss to cross-modal commutativity.

Atten Percept Psychophys

January 2025

Department of Psychology, University of Tübingen, Schleichstr. 4, 72076, Tübingen, Germany.

This paper is a follow-up to Ellermeier, Kattner, and Raum (2021, Attention, Perception, & Psychophysics, 83, 2955-2967), and provides a reanalysis of their data on cross-modal commutativity from a Bayesian perspective, and a theory-based analysis grounded on a recently suggested extension of a global psychophysical approach to cross-modal judgments (Heller, 2021, Psychological Review, 128, 509-524). This theory assumes that stimuli are judged against respondent-generated internal references that are modality-specific and potentially role-dependent (i.e.

[Analysis of factors influencing quality of life in patients with olfaction disorders].

Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi

January 2025

Department of Otolaryngology, Eye & ENT Hospital, Fudan University, Shanghai200031, China.

To explore the differences in quality of life among patients with olfaction disorders (OD) due to various etiologies and to identify factors influencing olfactory-related quality of life. This cross-sectional study enrolled patients with OD who visited the Department of Otolaryngology at Fudan University Eye, Ear, Nose, and Throat Hospital between February and June 2024. Psychophysical olfactory test was performed using the Chinese Smell Identification Test (CSIT), which was based on the Chinese population, with the TDI score used as the total score for threshold (T), discrimination (D), and identification (I) tests.

Audiovisual information reaches the brain via both sustained and transient input channels, representing signals' intensity over time or changes thereof, respectively. To date, it is unclear to what extent transient and sustained input channels contribute to the combined percept obtained through multisensory integration. Based on the results of two novel psychophysical experiments, here we demonstrate the importance of the transient (instead of the sustained) channel for the integration of audiovisual signals.

Olfactory Dysfunction in Children and Adolescents-A Diagnostic Pathway.

Neuropediatrics

January 2025

Department of Pediatrics, Pediatric Neurology, Neurometabolics and Prevention, Goethe University Frankfurt, Frankfurt, Germany.

Olfactory disorders have so far played a subordinate role in pediatric care, although children can also be affected. Due to a lack of awareness, the diagnosis can often only be made after numerous visits to the doctor, although it can significantly impact the quality of life. Olfactory disorders in adults are usually acquired, while congenital causes dominate in children.
